DKIM, next fighting tool?

SPF visibly no longer hoping to reach the envied status of standard to authentify email (or, more precisely, its sender) in order to attack SPAM at its source, the next credible candidate seems to be DKIM (Domain Keys + Identified Internet Mail) grouping the energy of two industrial giants: Yahoo! and Cisco. Future will tell.

No web spiders anymore?

This is the question I have been starting to ask since I noticed that my most recent SPAM honey pots (addresses automoatically generated to feed email address spider collectors) seem not to attract SPAM anymore.

It would tell that this technique is being abandonned by the spammers. Thanks for leaving me a message if you have some parallel observation on your own web site.

Reduce SPAM afterwards

A few tests I did show some possibilities to reduce received SPAM (not only filter it out), but with its limits.

On of the most common reasons to receive SPAM is to have you email address published on a web site. It is quickly collected by one of the spammers robots and becomes target for unwanted email.

Typically, the number of SPAM received will quickly climb up to 1 to 5 SPAMs per day.

What I find interesting is that if the address is then removed from the publishing web site (when it is actually possible), the SPAM will plumet down and after a few years this address will no longer receive more than a SPAM per week. Sometimes even less.

As a matter of fact, adress databases are not infinitely re-used. But notice that once the address is known it takes a very long time to change the trend.
