Spammers are learning, but so are we
Email customers of Montague WebWorks may have noticed a slight increase in the amount of spam they are receiving from out there. Mik Muller, owner of Montague WebWorks, contacted his anti-spam vendor, Linda Pagillo of Mail's Best Friend, for some advice. This is what Linda said...
Hi Mik. The last few weeks or so have seen a significant uptick in pre-tested spam with very high volumes. We have been getting quite a lot of complaints about it, but essentially, by definition, the spammer pre-tests their campaign against all available tests by sending samples to themselves on protected systems... when they have a version that gets past all of the tests they fire it off in huge volumes with their bot-net [a network of infected computers that send the email for them so it's not all coming from one server]. As much as possible we stay ahead of them by predicting what their next rounds are likely to be -- and often that works, but if they manage to pre-test against us then they beat that also.
As you have may have seen, these messages are bypassing all spam defenses including Declude, Commtouch and Message Sniffer. [BTW, Montague WebWorks uses Declude and Message Sniffer.]
We are working on adding additional tests in Declude to try combat this. Also getting samples to Message Sniffer will help Message Sniffer create rules as soon as there is a new wave to prevent some of these outbreaks. Send spam samples that slip through to firstname.lastname@example.org. I would like to see the traffic your Message Sniffer is currently dealing with.
