wow, the spammers have found me on Skype

I had no idea I had a long lost missing relative with millions in the UAE.


Hello Tobias,

Compliments of the day to you. I have tried to reach you on Skype phone, but your line was busy, so I decided to write you this message. I have been in search of someone with this last name "TOBIAS", so when I saw you online, I was pushed to contact you and see how best we can assist each other. I am Nadeem Ahmed Busheri, a Bank Officer here in U. A. E. I believe it is the wish of God for me to come across you now. I am having an important business discussion I wish to share with you which I believe will interest you, because it is in connection with your last name and you are going to benefit from it.

One Late Peter TOBIAS, a citizen of your country had a fixed deposit with my bank in 2004 for 36 calendar months, valued at US$18,400,000.00 (Eighteen Million, Four Hundred Thousand US Dollars) the due date for this deposit contract was last 16 of October 2007. Sadly Peter was among the death victims in the May 26 2006 Earthquake disaster in Jawa, Indonesia that killed over 5,000 people. He was in Indonesia on a business trip and that was how he met his end. My bank management is yet to know about his death, I knew about it because he was my friend and I am his account officer. Peter did not mention any Next of Kin/ Heir when the account was opened, and he was not married and no children. Last week my Bank Management requested that Peter should give instructions on what to do about his funds, if to renew the contract. I know this will happen and that is why I have been looking for a means to handle the situation, because if my Bank Directors happens to know that Peter is dead and do not have any Heir, they will take the funds for their personal use, so I don't want such to happen. That was why when I saw your last name I was happy and I am now seeking your co-operation to present you as Next of Kin/ Heir to the account, since you have the same last name with him and my bank head quarters will release the account to you. There is no risk involved; the transaction will be executed under a legitimate arrangement that will protect you from any breach of law.

It is better that we claim the money, than allowing the Bank Directors to take it, they are rich already. I am not a greedy person, so I am suggesting we share the funds equal, 50/50% to both parties, my share will assist me to start my own company which has been my dream. Let me know your mind on this and please do treat this information as TOP SECRET. We shall go over the details once I receive your urgent response strictly through my personal email address,

We can as well discuss this on phone; let me know when you will be available to speak with me on Skype. Have a nice day and God bless. Anticipating your communication.

Nadeem Ahmed Busheri.

thanks Robert, importing Thunderbird to Outlook 2007 under Vista

for the easiest guide to converting thunderbird to Outlook mail. Back on Outlook. Thunderbird doesn't make the change back easy. The only change I have to the process is that under Vista no more Outlook Express. You have to use Windows Live Mail. In Windows Live Mail, drag and drop all the .EML files converted from thunderbird then do "Export to Exchange". Then open Outlook and open the .pst that is created, copy messages in. Pretty stupid that you have to pull the mail through windows live mail to get to outlook, but that is MS fo you.

Bill still hasn't solved spam

Frequent readers know I am on the board of directors of Cloudmark, the leading anti-spam company. Today this story: You've got spam -- more of it than ever reminded me that the problem hasn't gone away. In fact as the article points out in the last couple of weeks it has gotten much worse. Thankfully Cloudmark has kept up and only a couple sneak through. I run both the Exchange Edition and the Desktop to filter both my Exchange and POP3 mail. If you have seen your filter falter under the most recent crush, upgrade to Cloudmark!

Verizon anti-spam a mess

Ok, I am an investor in Cloudmark, so I am biased, but I have always believed that white and black lists simply don't work at scale and Verizon's new system is showingn that in spades: Slashdot | Verizon's Aggressive New Spam Filter Causing Problems. The real problem is that as spam filtering goes deeper into the network and in fact sucks, users will start missing mails and not even know it. I see a huge user back-lash coming.

new pew study shows some numbness to spam

A new Pew study: komo news | Have We Surrendered To Spam? shows a certain numbness to spam. The number of people who trust mail less or are "bothered" by spam has flattened out . That doesn't mean it is any less of a problem, just that we are used to it. I am glad to see the number of people "trusting" mail flatten out. It would be a serious blow to the whole internet economy if a material number of people stopped trusting mail.

Phishing up to 33 million per week

Ouch...Linux News: Business : Phishing Attacks Number 33 Million Each Week. Have you been sucked in? This is the #1 threat to e-mail today. If you can't trust it, why? I posted earlier that Gartner predicted a meaningful fall off in on-line e-commerce due to spam. This is before phishing. I will be quite interested in the e-commerce numbers this summer after we have had a substantial flood of phishing. I expect them to still be up, but I also expect to see a meaningful haircut on the growth numbers and a meaningful number of people more nervous about e-mail based transactions.

Installing MTBlacklist again

Installing Jay Allen's excellent plugin: MT-Blacklist - A Movable Type Anti-spam Plugin again. When I upgraded to MT 3.1, I turned on comment authentication with typekey and that pretty much stopped comment spam. But now the spammers have moved over to Trackback Spam and I am getting hit with 30-50 a day. Time for a solution. Too bad Blacklist is just a blacklist. Would be nice if there were some logic like is available in Cloudmark for e-mail. You could do the same spam DNA on trackback spam. The standard stuff in MT of IP blocking doesn't work because they change the IP address every time. But logic around the offer and the URL should catch most of them. Most of them are about poker. Die trackback spam, Die!

80% of mobile users have received SPAM

Mobile Pipeline | 80% Have Received Mobile Spam, Survey Finds. The article doesn't say if it is SMS spam or e-mail Spam. I wouldn't doubt it if it was e-mail accessed on a mobile since all e-mail recieves alot of spam. But SPIM (SMS) is much smaller today. you need to pay for an SMS message and go through one of a few regulated gateways to the wireless networks, so I doubt this was SMS.

New Microsoft Anti-Spyware conflicts with Dantz backup

I have been running Webroot SpySweeper, the best anti-spyware program out there. But when Microsoft launched Microsoft Windows AntiSpyware (Beta) Home I had to give free a try. This is just the rebranded version of the software Microsft bought earlier this year. It seems that they didn't bother to do much compatibility testing.

I installed it on both my laptop and my desktop at home. On the desktop computer I run Dantz backup. The laptop and other computers on my LAN have the client software on them. I did not install msSpyware on my wife's Dell laptop. I have a back-up script that runs every night around 2:00am and backs up all the computers on the network to a spare harddrive. After two days I checked the back-up status and noticed that my laptop wasn't being backed up. There were "not sufficient permission" errors and "Can't find back-up client" errors. In windows the two computers can see each other and share common drives. The only thing I changed was adding MS Spyware. Of course the behavior of Dantz could look like spyware. But I didn't even get a message like "program Dantz is trying to access the harddrive". I removed the Ms Spyware from the laptop thinking that it was preventing the back-up program from attaching. The script still failed. So I turned off spyware on the main desktop computer. The script ran just fine. So MS Spyware was not allowing the main back-up machine to reach out and attach to the back-up client and copy down files. Again no message. You would think it would be smart enough to tell the difference between a back-up program and spyware. Bye Bye Msft anti-spyware until you figure this out!

FTC issues final definitions and guidelines of SPAM under Can-Spam

Nothing like an effecient government. Nearly a year after the law went into "effect", the FTC has finally gotten around to issuing guidelines and operational details with which some kind of real regulation may be implemented. I don't think this work will effectively reduce the flood of spam either. But here it is:

FTC Issues Final Rule Defining What Constitutes a “Commercial Electronic Mail Message”

Notice Includes Criteria For Determining the “Primary Purpose” of an E-Mail Message

The Federal Trade Commission today issued final regulations to facilitate the determination of whether an e-mail message has a commercial primary purpose and is subject to the provisions of the CAN-SPAM Act. The CAN-SPAM Act, which took effect January 1, 2004, requires the Commission to issue regulations “defining the relevant criteria to facilitate the determination of the primary purpose of an electronic mail message.” The FTC published a Federal Register notice of proposed rulemaking (NPRM) on August 13, 2004, seeking public comment on its proposed primary purpose criteria. The NPRM followed an Advance Notice of Proposed Rulemaking, issued on March 11, 2004, on this and other related issues raised by the CAN-SPAM Act.

As detailed in the Federal Register notice, which will be published shortly and can be found on the Commission’s Web site as a link to this press release, the final Rule is substantially similar to the proposal contained in the NPRM, but adds a criterion for determining the primary purpose of an e-mail message containing only “transactional or relationship” content, among other minor changes. The CAN-SPAM Act regulates both commercial messages and transactional or relationship messages. The notice makes clear that the Commission does not intend to regulate non-commercial speech through the Rule. The notice also addresses public comments received about the constitutionality of the CAN-SPAM Act, as well as of the FTC’s “primary purpose” criteria.

The final Rule sets forth criteria for determining the primary purpose of various kinds of e-mail messages. These include:

Finally, the final Rule incorporates the “Sexually Explicit Labeling Rule” as promulgated in April 2004. The Commission vote approving publication of the Federal Register notice was 4-0-1, with Commissioner Jon Leibowitz not participating.

Copies of the Federal Register notice are available from the FTC’s Web site at and also from the FTC’s Consumer Response Center, Room 130, 600 Pennsylvania Avenue, N.W., Washington, D.C. 20580. The FTC works for the consumer to prevent fraudulent, deceptive, and unfair business practices in the marketplace and to provide information to help consumers spot, stop, and avoid them. To file a complaint in English or Spanish (bilingual counselors are available to take complaints), or to get free information on any of 150 consumer topics, call toll-free, 1-877-FTC-HELP (1-877-382-4357), or use the complaint form at The FTC enters Internet, telemarketing, identity theft, and other fraud-related complaints into Consumer Sentinel, a secure, online database available to hundreds of civil and criminal law enforcement agencies in the U.S. and abroad.

ouch $1B has gotta hurt

Well it seems that the courts may be making progress against spammers Judge Awards $1 Billion in Spam Lawsuit. Of course there is no way that the plaintif will ever recover $1B from the spammers, but it is a good start. Yet the courts are a one step forward, one step back story. In the same week, a judge in MD declares that state's spam law unconstitutional on the rounds that it tries to regulate interstate commerce (which is solely a federal job).

Yahoo launches DomainKeys with Earthlink

InformationWeek > Security > Yahoo Aims Crypto App At Spam > November 22, 2004. I am incredibly skeptical of these efforts. When you have to change the fundamental transport layer and get everyone sending mail to abide by your standard in order to receive protection, it is a non-starter. And does Yahoo have the chops to drive an e-mail standard? Well they do run more mailboxes than anyone on the planet, but they are not a software company and have not been big standards drivers in the past. It will be interesting. But I predict failure of DomainKeys.

The universal spam solution critique...

Saw this on on SlashDot again today applied to the FTC idea to put out a bounty on Spammers. Use the checklist for each new idea you hear. Fun AND useful.

Your company advocates a

( ) technical ( ) legislative ( ) market-based (x) vigilante

approach to fighting spam. Your idea will not work. Here is why it won’t work. (One or more of the following may apply to your particular idea, and it may have other flaws which used to vary from state to state before a bad federal law was passed.)

( ) Spammers can easily use it to harvest email addresses
(x) Mailing lists and other legitimate email uses would be affected
(x) No one will be able to find the guy or collect the money
( ) It is defenseless against brute force attacks
( ) It will stop spam for two weeks and then we’ll be stuck with it
( ) Users of email will not put up with it
( ) Microsoft will not put up with it
( ) The police will not put up with it
( ) Requires too much cooperation from spammers
( ) Requires immediate total cooperation from everybody at once
( ) Many email users cannot afford to lose business or alienate potential employers
( ) Spammers don’t care about invalid addresses in their lists
(x) Anyone could anonymously destroy anyone else’s career or business

Specifically, your plan fails to account for

( ) Laws expressly prohibiting it
( ) Lack of centrally controlling authority for email
(x) Open relays in foreign countries
( ) Ease of searching tiny alphanumeric address space of all email addresses
(x) Asshats
(x) Jurisdictional problems
(x) Unpopularity of weird new taxes
(x) Public reluctance to accept weird new forms of money
( ) Huge existing software investment in SMTP
( ) Susceptibility of protocols other than SMTP to attack
( ) Willingness of users to install OS patches received by email
( ) Armies of worm riddled broadband-connected Windows boxes
( ) Eternal arms race involved in all filtering approaches
( ) Extreme profitability of spam
(x) Joe jobs and/or identity theft
( ) Technically illiterate politicians
( ) Extreme stupidity on the part of people who do business with spammers
( ) Extreme stupidity on the part of people who do business with Microsoft
( ) Extreme stupidity on the part of people who do business with Yahoo
( ) Dishonesty on the part of spammers themselves
( ) Bandwidth costs that are unaffected by client filtering
( ) Outlook

and the following philosophical objections may also apply:

(x) Ideas similar to yours are easy to come up with, yet none have ever been shown practical
( ) Any scheme based on opt-out is unacceptable
( ) SMTP headers should not be the subject of legislation
( ) Blacklists suck
( ) Whitelists suck
( ) We should be able to talk about Viagra without being censored
( ) Countermeasures should not involve wire fraud or credit card fraud
( ) Countermeasures should not involve sabotage of public networks
( ) Countermeasures must work if phased in gradually
( ) Sending email should be free
( ) Why should we have to trust you and your servers?
( ) Incompatiblity with open source or open source licenses
(x) Feel-good measures do nothing to solve the problem
( ) Temporary/one-time email addresses are cumbersome
( ) I don’t want the government reading my email
(x) Killing them that way is not slow and painful enough

Furthermore, this is what I think about you:

( ) Sorry dude, but I don’t think it would work.
(x) This is a stupid idea, and you’re a stupid company for suggesting it.
( ) Nice try, assh0le! I’m going to find out where you live and burn your house down!

MSft Sender ID rejected by IETF

The Register reports that IETF has bounced Msft's Sender ID proposal. The reason is intermingling of Msft patents. The industry standards board is loathe to endorse anything that requires licensing from Microsoft. Msft again shoots itself in the foot.

Lone programmer introduces private e-mail service

PRESS RELEASE: David Did What Goliath Didn't -- He Stopped Spam. Well the self released press release is a little mis-leading and self serving, but this guy has put up a very simple version of what many people are looking for. A post office monitored e-mail system. Basically you have client software which checks for and applies a "stamp" from the central server. The system only hands out stamps at a certain rate, so if you are a spammer and trying to send lots, the server won't give them to you. You can set your e-mail client to only accept "stamped" mail. There are of course ways to game this system, and while he talks about it as an "open" system, in the end it is another walled garden. But some version of this "1st class mail" will get traction. The key is how to deal with exceptions and people outside your walled garden who you want to get in. Exactly the same problem as white lists.

FCC tries its hand regulating SPAM on phones

The FCC has tried a new rule to combat mobile spam. I would guess that they have more leverage over that (relatively) closed network than the internet in general. In mobile, there are fewer entry points into the network and therefor more control. There are always ways in and around though. And I also see that legitimate players like SOHU can still run afoul of the laws.

New Consumer Reports article on how ineffective CanSpam is

Bradenton Herald | 08/15/2004 | Consumers: CAN-SPAM act no help. When do consumers hold politicians accountable? I know everyone in DC voted for the thing because they wanted to pass something that they thought their constituents wanted (and they did), but what happens when their solution doesn't work? Will the electorate hold them accountable? Spam legislation isn't typically a voting issue in an election, but maybe it should be. If they can't pass effective laws around something like Spam, what makes you think they are doing a good job in other areas?

Make sure you keep that Cloudmark software active.

Cloudmark saves me from getting hooked!

Opening my mail this morning, for a moment I saw a very official looking mail from US Bank with the title "U.S. Bank regular verification! [Fri, 02 Jul 2004 22:12:31 +0600]". Sounds official huh? But just as quickly as I saw it in my inbox, it disappeared. Huh I sayz, that looked official, I bet Cloudmark made a mistake. So I go to the Spam folder and look at it. Now I used to have an account there but haven't used it in a couple of years, so that should have been my first clue. No, this mail wanted me to click on a link to "verify my information". The exact wording is: "As the Technical service of bank have been currently updating the software, we kindly ask you to follow the reference given below and confirm your data, otherwise your access to the system may be blocked." The poor grammer was a clue. Total Phishing! Cloudmark caught it and put it where it belongs. Thanks Cloudmark! Did your Spam filter catch it?

The UK is ground Zero for phishing scams. Now they are seeing the Russian and Chinese Mafia enter since so much money is at stake. I recently read a study showing over 2M Americans have actually fallen victims to these frauds and handed over personal financial information. The success rate of these mails is greater than any other direct marketing. Because they look real! This is a true threat to e-commerce as we know it. A recent PEW study already shows that 30% of their respondents are using e-mail less due to these fraudulent e-mails. It is time for anyone with any business on the net to take notice.

SPF embracing Microsoft Sender

On mengwong's site He announces his integration of Microsoft Sender Policy thingy into "new SPF". Trying to stay relevant. There is still a VERY long way to go for anyone to change the e-mail standard in a generally accepted way. Don't look for agreement any time soon.

Spam Phisher Fries!

A 20-year-old Texas man has been convited of “phishing”, and sentenced to 4 years.

Zachary Hill was found guilty of sending email which appeared to be from PayPal and AOL, telling his targets that they needed to provide credit card and bank account numbers or their accounts “would be cancelled”. 

Did it work?    Apparently to the tune of at least $50,000!

Was it worth it?  Well, at $12,500 per year, before attorneys fees, if it was worth it to him, he’s probably going to be experiencing a better standard of living for the next four years than he’s used to.

FTC settles two anti-spam suits for $122,500

Humm, is reporting that the FTC has wettled cases against two spammers who allegedly used spam to trick recipients into accessing sexcually explicit materials. These messages didn't conform to the CAN-SPAM criteria. There was no sign-off ability. This looks to me like one of the first settlements.

Gartner Zinger on impact of Phishing schemes

From the above mentioned report out this week:

Gartner believes that the double-digit expansion of U.S. e-commerce will slow down unless service providers adequately address consumer security concerns. A future Gartner note will outline emerging antiphishing solutions, ranging from digitally signed e-mail to managed antiphishing services. Without the implementation of phishing antidotes, consumer trust will further erode and annual U.S. e-commerce growth will slow to 10 percent or less by 2007 (0.6 probability).

Wow. I think that is a bit agressive, but it certainly gets your attention doesn't it? Consumer confidence erroded by Phishing scams and other problems results in a material drop in overall on-line commerce growth. Certainly a good way to scare your clients into calling you.

Ironport and Msft not a big deal

This announcemen today: Microsoft taps IronPort in spam fight | CNET at first blush sounds like a big deal. Of course it does because the start-up Ironport wrote the press release. But dig deeper...

According to my Microsoft contacts, Microsoft has been testing Bonded Sender for “quite awhile” and just now are getting around to endorsing it. Bonded sender is basically a white list with a lot of “trusted” third parties and policies behind it. They will add the “bonded sender” rating into their decision tree at MSN and Hotmail when determining “spammieness” of a mail. It is just one more data point that Microsoft is saying they will trust. Good PR for Ironport. No money for them. No guarantee their “bonded” mail will get through (it still may fail other tests).

At first blush, this may seem to conflict with Microsoft’s Caller ID proposal. It takes alot of brain cycles to parse the difference, but essentially Caller ID is a small technology fix to prevent forged headers. Bonded Sender is an independent third party validating senders. I am sure Microsoft believes there are benefits to not being in the bonding of senders business, while Yahoo and AOL believe they want to be in that business. It is clear that Microsoft is taking the partner with third party approach for sender authentication as opposition to Yahoo/AOL approach.

In the end, good PR for Ironport. Probably no money. Don't know if they will sell any more mail pumps to send stuff to Hotmail users.

Radicati Group Releases New Study "Cloudmark: Spam Reduction Analysis"
Research Study Shows Impressive TCO and Productivity Savings, Plus a High 94% Spam Reduction Rate for Cloudmark's Authority Enterprise Solution
PALO ALTO, CA -- (MARKET WIRE) -- 04/20/2004 -- The Radicati Group, Inc., a leading market research firm, released today a new study analyzing the Total Cost of Ownership (TCO), Productivity Savings, and Spam Reduction Effectiveness (SRE) for leading Anti-Spam vendor Cloudmark.
With the volume of junk messages escalating every day, spam is quickly turning from an annoyance issue for users, to a major productivity loss problem for corporations. Cloudmark's large enterprise gateway solution, Cloudmark Authority™, demonstrated a productivity savings per user per day of $2.21. This figure means an annual savings in excess of $5 million for a 10,000 person company.
"We felt it important to conduct this study to report a real-world scenario where an anti-spam solution is actually deployed and running over time at an Enterprise gateway," said Sara Radicati, President and CEO for The Radicati Group. "It is encouraging to see the results of Cloudmark's performance at actual customer sites."

Google: the ultimate spam machine

GMail is running into more trouble. Not only are their privacy concerns with their plan to read everyone's e-mail, the plan to append "targeted" ads apparently may fly in the face of many of the anti-spam laws passed recently. Australia certainly thinks so. California is also complaining. I understand how it would be a violation when a third party appends ads without your expressed consent to the product or content. I wonder if the users had more control over the ads if it would be less legally offensive?

More evidence of collaterol bad SPAM filter damage

A bunch of articles recently have pointed to e-mail publishers not being able to get their wares through increasingly strick spam filters. Email lists struggle under spam avalanche - ZDNet UK Insight. This is a real problem. In the early days of e-mail, one of the most useful things was being able to receive e-mail news letters on different topics. Now many poorly written filters are doing a bad job with these kinds of mail. That is why it is important to pick a good filter. Like Cloudmark. It is possible to make good decisions on what is and what is not spam. Part of the problem is that there are alot of ineffective spam companies out there actually selling customers. Some customers conclude "all spam solutions suck". They should be concluding, "my spam solutions sucks and I need a new one." Start looking for spam solution replacement sales.

Cloudmark has a rating program that is an additional step to help valid e-mail publishers get through their client.

Spammer looses lawsuit, but not for what you think

There has been much debate as to the effectiveness of laws against spammers. So when you read that Spam Fighter Habeas Wins One you might be inclined to believe the laws are working. But look closer. Habeas is using old school trademark and copyright law. In their system, e-mailers need to have their copyright Haiku in the e-mail to get through the filter. A spammer who forges the Haiku is guilty of copyright infringement. Not of breaking a SPAM law. Very intriguing. And apparently working.

The slippery slope of content analysis of messages

The police need a warrant to tap your phones. You can have a very high degree of confidence under normal circumstances that your phone calls are not being overheard. But what about your e-mail? Or instant messages? Content scanning really started with Viruses. No-one wants viruses, so we all install software to scan messages and identify offensive viruses. And then comes SPAM where we want the offense to disappear as well. Then some corporations have certain "content" policies or IP protection policies that alert them when certain key words are in messages. Now Google's GMail wants to scan messages and determine what ads to attach to them.

Colin Fahley writes very insightfully:

Google's new "G-Mail" service (run by "G-Men"?!) is a paranoiac's
nightmare come to life: an e-mail system that analyzes each piece of
mail not simply for spam detection and virus detection, but for
targeted advertising! Want to embarrass a friend using G-Mail?
Send an e-mail mentioning only "farm sex" or "kiddie porn", and
who knows what "targeted advertising" he or she will get. Perhaps
there will be a knock on the door from the FBI.

Despite promises that content analysis will be isolated from any
record-keeping, and totally performed anonymously by computer
algorithms, the fact is that one's mail is being analyzed, and
even requests for banner ads represents an information leak --
connecting your interest with your IP (since your browser fetches
the banner ad from whatever source). With a modest amount of
extra data mining, an "anonymously targeted" banner ad betrays
your identity.

So where are the limits? You think what you write to your girlfriend is your own? Maybe you encrypt it? But then the Virus, Spam, content filtering, and advertising bots will have to break into it to do their work. If they can't your message will not be let through. It is a totally slippery slope. Where are the edges???

My friend Eric on encryption in e-mail and some good pointers

In response to an e-mail from me, my friend Eric sent these useful thoughts and pointers on encryption.


don't know if you've found these, but they're somewhat helpful different points of view:

i assume you know about these guys:

if you're ready for some heavy reading, this hase some interesting ideas:

this is a general interesting list of whitepapers:

what are people going to use encryption for?

is it ever going to come to a point that the email that goes between my mother and i is encrypted? even if it were just clicking a button on and off, would it even be worth doing?

it's just my general impression that people don't seem to feel they have much to hide in general, and i would have to think part of that is because they don't.

would the world be a safer place if everything was encrypted? likely, but i don't think that it'll really happen until it's just an automatic feature in hotmail (where it detects that you're talking with someone who accepts encrypted email and automatically turns it on).

the only problem with that, is that if you don't have the user conciously aware that they are using encrypted data (if you don't require extra or more stringent passwords to get at your private key, etc) it basically defeats the purpose of most of the encryption: if you can just type in the name of their dog as their password and get into their email, which automatically shows you the decrypted versions of their emails, what good did it do that it was encrypted?

so.. things are marginally improved -- people can't sniff email in transit and see everyone's messages. so that's good.. but.. i don't know who will pay for that incremental improvement.

Secure e-mail now

A couple of readers have asked if there are any easy to implement mail encryption schemes available to an individual today. Unfortunately the catch here are the words "easy to use". Of course most mail clients support public/private key pairs (most based on PGP), but the set-up is a hassel. If you like pulling fingernails, read how to configure Outlook here. You have to pay for the keys and provide a high level of authentication (your first borne) to get the highest level certificates. And then of course everyone you send mail to needs to do the same thing. Key pairs are a very heavy weight solution to the problem and I do not believe will ever be widely adopted.

There is hope on the horizon though for a lighter weight keyed encryption. It is called Identity based encryption. The major proponent is Voltage Security. The promises are good, but this one fails another test: "today". It is not yet available. And it looks like they will first sell to government and enterprises with no option for a single end user product. Of course there are other secure messaging providers to the enterprise like Tumbleweed, PostX and a long list of others. But again, those sell to the enterprise or into verticals.

There are "secure e-mail providers" that will sell you a new acocunt that is "secure" to various degrees. A Quick search of Google for "secure email" results is a long list. But you need another e-mail address. And different services offer different levels of "Security".

Another approach is to basically not send the e-mail to another client, but rather to a secure server, and forward the receipient a mail with a HTTPS link in it to the message in a browser which requires authentication, passwords and all that. This approach is lighter weight than key pairs, but takes you out of your traditional mail client. And again, most solutions are for enterprise. One Portland company doing this is Kryptiq. They started out as a generic secure e-mail company, then focused on health care as a vertical to get deeper into the workflow. Again, not for consumers.

Now wouldn't it be nice if there were a client plug-in that just worked without alot of central set-up and was seamless to others? In other words if someone outside the system sent you a mail, you would get it. If you sent a mail "securely" to someone without the system, they could sign-up or get it very easilly. Or request a non-encrypted copy if they didn't want to sign up?

Ok, I am working on it.

All designated sender schemes blow chunks...

Props to Technology Review for getting my synapse's connecting on this one. All the designated sender schemes out there basically attack the problem of forging domain headers. That way you can't say you are from Yahoo and not really be. But spammers are free to buy as many domains as they want and keep sending mails from there. I still believe that a combination of client and server techniques are required.

Here is the meat of their arguemnt:

"Yahoo!, Microsoft, and the SPF working group are all backing competing proposals that have been characterized as “designated sender." (America Online has endorsed and is experimenting with the SPF version.) They all attempt to give a receiving e-mail server a way to determine whether the "From" address on an incoming message has been forged.

These anti-spam methods, if widely adopted, would certainly devalue one important tool in the spammers’ current repertoire. We should keep in mind, however, that spammers have many tools. The best these techniques can do is to keep a spammer from using your domain (or AOL’s, or Yahoo!’s) as a "From" address. Spammers could legally acquire thousands of valid domains at little cost, provide valid SPF and Caller ID records for them, and discard them when they drew the attention of spam-fighting organizations.

Such designated sender techniques have other drawbacks as well. One problem is that legitimate mailing lists would become difficult to operate. Another is that e-mail forwarding services, such as those supplied by MIT alumni and other affinity groups, would be broken. "

.TM domain registar implements SPF

The Register reports that the domain registar of .TM domains has implemented SPF. They are trying to maintain the "exclusiveness" of their domains. Here is how they explain it works.

SPF (Sender Policy Framework) itself is a very simple yet effective method of cutting down spam. Internet domains already have MX records tied in with their basic DNS information that say which mail servers receive email for that machine. All SPF does is provide MX records for the domain’s mail servers that send email.

As such, when an ISP receives an email, it looks at the domain, looks up the DNS record and if the mail server it came from is not one mentioned in the MX records, it either deletes it or pushes it to one side for review. Since a large number of spam messages are “spoofed” in order to make it look as though the email is coming from elsewhere, such a system would reduce the number of spam as well as make tracking down spammers easier.

Spam tactics roundup

ZD Net just did a fairly good roundup article on the major ISPs (Msft, AOL, Yahoo) guys efforts to fight SPAM. Technology solution to slicing spam lags - News - ZDNet. The upshot is that we have a balkanized set of proposals all incompatible and coming at the problem from slightly different angles. All three of the majors are focusing on the piece that I have pointed out though, which is authentication. SPF is a server authentication technique. Yahoo DomainKeys is sender/message header authentication. Microsoft's Caller ID from microsoft also uses DNS for authentication but targets the author or header and is better (they say) at authenticating forwarded mails than SPF.

A good article to get a roundup of current proposals. But you won't find any magic potion here.

Spam Spin

I was intrigued by the Corvigo acquisition by Tumbleweed, so I read the press release and came across this little tidbit.

Corvigo's Linux-based anti-spam appliance, MailGate, was rated #1 against major competitors in real-world testing by InfoWorld in February, 2004. ( Tumbleweed can now offer customers the broadest, most flexible options for stopping spam with either the MailGate hardened Linux-based appliance, or Tumbleweed's Email Firewall, a globally scalable Windows-based enterprise software solution. In addition to award winning anti-spam capabilities, Tumbleweed's Email Firewall offers an integrated set of anti-virus, intrusion detection, content filtering, email relay, encryption and authentication capabilities.

So I go read the article:InfoWorld: Exclusive: CipherTrust, Corvigo, and MessageLabs lighten the spam load: February 13, 2004: By Logan G. Harbaugh: Security. It is a round-up article. Not a shootout. They don't pick a winner. But Corvigo says they won and leveraged that claim into an acquisition. Wow.

Another blow against Blog Spam

TypeKey is Six Apart's identity system for blog commenting. Basically they are trying to get a the root of Spam before it kills blogs. SPAM is an authentication problem. If you check authentication of a person before they write something against a central database and that database is kept clean of offenders, then you can stay pretty clean. That is the problem with SMTP today, no authentication. I will try this one out on my blog.

SPAM is an identy problem

There is a bevy of proposals to solve SPAM at the authentication level. Read a good overview of them here. At the end of the day, the openness of SMTP is its greatest weakness. The thinking goes that if you set up some user/server authentication system then e-mail clients can do a better job on deciding which e-mail they want to receive. A problem today with spam filtering techniques is that there are many different rules applied to e-mail at the receiving end to determine if it can come it. And those rules are applied to to data (the e-mail) that cannot be validated as to it's authenticity, origin, or sender. So you guess. Spam filters vary on their ability to guess well. With more trusted data in the message, these systems could make more informed decisions. But that still doesn't solve the issue that everyone has different tolerances for what gets through and what doesn't. People who favor white lists today (not reading mail from anyone they don't already know), are also probably the people with Telezappers and signs on their front door saying "no soliciting". User's tolerance varies, therefore the systems must vary, be configurable. A key to any system is improving the ability to verify content, origin and sender of any messages. Most current proposals are proprietary in some way. This is too important a piece of the new economy to entrust to one vendor. Why can't we all just get along...

I am betting that a market based solution from a small, unthreatening company will be what gets traction.

More lawsuits by big ISPs and Microsoft on SPAM

Today lawsuits were filed by Microsoft, AOL, Yahoo and Earthlink under the new Can-Spam law. It is the first time these four (who make up the vast majority of non-enterprise mailboxes) sued under the new law. They have sued before under various local laws. It will be interesting to see how the stick part of the strategy actually works. The SPAMMERS will try the first ammendment trick and many others to stay in business. I did my own little test of SPAM around the new year and saw a slight drop off, but that apparently was seasonal. Talking with the guys at Cloudmark, they have seen a steady up and to the right trend in spam. No slowing down or leveling off in sight.

Symantec ups the anti in Spam wars

Techweb > News > Symantec, spam, virus, Microsoft Exchange, > Symantec Updates Anti-virus, Anti-Spam Support for Exchange 2003 > March 8, 2004. Symantec has always been the best positioned to extend their anti-virus stuff to the spam space. They just rolled out some of that today. While I haven't tested their product (and neither have the reviewers) they say they are using a number of next generation techniques that are closing the gap with some of the early leaders like Cloudmark. In the past Symantec has had scaling problems with their SPAM engine. And this time they are utilizing many of the new features in Exchange 2003 which is yet to be broadly deployed. But the hoards are a 'comin.

Will Throttling save us from spam?

Techweb > News > New Products Try To Spurn Spam > New Products Try To Spurn Spam > February 18, 2004. A couple of products have come out recently trying to change the economics of spam. These are in the mode of "slow 'em down". The idea is if you find a mail server which seems to be spitting out "too many mails", then just throttle down it's bandwidth to a trickle. You can do this on the entry points of the network, or you can try to do on your own edge just before your SMTP server. These tactics are more of the same heavy handed, sledgehammer variety that create lots of false positives. The ultimate form of this is to just unplug yourself from the net. And I am not sure these throttling techniques actually cost the spammer any more resources. If I am doing it on the edge of my network, chances are that the mails are all cached in the network between the spammer and my IP address. So the real cost is in the transit points. If you put the chokepoint closer to the spam source, they just move them. If spam sources were easy to find, this would be an easy problem. It is not.

Another tactic for SPAM, a "caller ID"

Internet Magazine - Microsoft/Sendmail deal. Spam is fundamentally an authentication problem. Who is sending the mail? Is it someone I want to receive stuff from? Are they who they say they are? Do I have a prior relationship with them? Today many spammers forge header details to hide their true origin. Today at RSA Microsoft introduced a plug-in to Sendmail's MTA that is basically an authentication signature. It lets the MTA verify the message source. There will be free and commercial versions of this. Something only Microsoft could push. Little steps. I wonder what has to happen on the publisher side? That hasn't been explained yet. Something too expensive on the sender side is not going to work.

One interesting tidbit is that France thinks only 0.2 percent of their e-mail is SPAM. This is from people who eat duck liver. And to the French, those ads offering body part enlargement and beastiality pictures are valid commercial products. Oh, and probably "art" too.

more Microsoft FUD on the SPAM front

The reason SPAM works today is that the economics work. Many people have solutions that propose to change the economics. The real thing you want to do is raise the cost of sending an e-mail. But not so much that normal people sending a normal amount of mail will notice or have to pay extra. One way is to charge micropayments for each e-mail sent out. And get a credit for each received. The probelm with clearing all those micro-payments will make that one not fly.

Then there is the idea of making senders pay with something else. Like CPU and memory power. Apparently Microsoft has figured this out BBC NEWS | Technology | Microsoft aims to make spammers pay (the technique has been around for more than a decade) and is thinking of adding it to Exchange. I don't think even Microsoft has enough MTA's out there to make a change like this. And it has the potential for back-firing in many ways just like challenge response does (causing the recipient to be a spammer).

The thinking is along the right path. Change the equation. Microsoft won't be the one that fixes it though.

More ramblings on SPAM

It is funny read comments from people new to the SPAM debate. Especially those who think there is a simple solution. Like a "do not spam" list. These people don't understand the technology or the history of the SPAM fight. There has been grassroots efforts for years. The reverse of a do not spam list is a blacklist of senders. These have been around for years and don't work. Wired did a good job summarizing the reasons the do not spam list will not work.

In case you too are missing some of the research material on the true costs of SPAM, I am re-posting here an excerpt from NW Fusions with pointers to the recent studies:

In a recent report by Nucleus Research, spam was estimated to
cost U.S. companies over $800 per employee per year in lost

Ferris Research estimated that U.S. corporations in 2003 will
spend $10 billion to cope with spam:

Some projections from the trends are alarming (others might say
"alarmist"). If the growth in spam continues, according to
Jupiter Research, "the average e-mail user should expect to
receive nearly 3,900 junk e-mail messages per day in 2007":

Public rage against spam is rising. According to a November 2002
poll by Harris Interactive, an overwhelming majority (80% of a
sample of 2,221 adults) of the U.S. Internet-using public found
spam "very annoying" and 74% of the sample wanted spamming made

"spamhole is an open project. Hopefully, through user's and developer's contributions, we will amass a collection of spamhole implementations spanning all commonly used platforms, programming languages, etc. Ease of configuration and use are the primary objectives, for the easier to use by the non-techical layperson the implementations are, the more widely adopted and used spamhole will become.""

DDos attacks cause two anti-spammers to throw in the towel

For quite some time, the anti-spam fight has been waged by volunteers. People who hate spam so much, they take their own personal time and maintian Black Lists or gather stats that "out" the spammer's ISP locations and tricks. I found an article on two of them that were recently forced to pull down their lists because the spammers sent targeted DDos attacks that shut down their servers. They used the same servers for their regular business and had to pull back from their volunteer anti-spam work. Ed Foster's Gripelog || Attacks on Anti-spam Sites Show Unresponsiveness of Legal System This is yet another failure of the volunteer system of anti-spam control.

One way for companies to gain credibility with the masses is to provide some kind of free service to the industry. Ironport is offering SenderBase. Basically a list of which ISPs and IP addresses are creating the most e-mail on the internet. I guess it is one piece of information that a mail administrator could use to verify senders.

The problem with so many of these one trick pony techniques to SPAM is that they are just that. And typically you need more than one approach. Or layers. For example, just because a domain is sending alot of e-mail doesn't mean it is spam. It could be a listserver. It could be any number of valid senders. The problem is multi-faceted, the solution needs to be too.

Network World just did a comprehensive review of SPAM solutions. <a title="Anti-spam buyer's guide" href="">Anti-spam buyer's guide</a> The result? We are on V 1.0 products that still need work on features. Not so much in accuracy (Cloudmark did VERY well there), but in usability, configuration, and other enterprise and end user features/controls. Unfortunately the products in this review are those of about 4 months ago and products have changed. Many of the things the reviewer ding'ed Cloudmark on they now have. But that is how reviews go.

One interesting issue this review brings up is that there are a set of "legacy" criteria for spam filters that many reviewers are using. They are actually features or techniques to fight spam, not necessarilly things that drive to the ultimate goal: accuracy and reliability. One example is White lists and Black lists. This is a feature on many reviewer's checklist. If you don't have it, you get dinged. But what if White and Black lists actually create more problems than they solve (which they do)? What if there is a better way to get higher accuracy and lower false positives (there is). In the end, the product that works the best and has the lowest total cost of ownership should be the one that wins. But that isn't how reviewers are reviewing just yet.

The problem with all these approaches, is that there are many legitimate patterns that can look like this. Like someone forwarding their e-mail from a domain host to an ISP. That is typically a batch process, so they spurt all the e-mail over at once every couple of hours or so. Could look like a spammer. Or newsletter publishers. Or valid commercial senders like Amazon. They all do mail drops during down-times in the network that all go out at the same time. These approaches are all too "dumb" to be a real solution.
