I received an email from new reader Sylvain asking about Alaksandr, the Russian sendmail spambot that was plaguing me for months. It seems that Sylvain is having to deal with Alaksandr and asked me for some help, having read one of my posts detailing the problem (and if you are having déjà vu, it's not a glitch in the Matrix [1]).
I told Sylvain about my solution—removing the email accounts Aleksandr was spamming. I also decided to update each of the posts to point to my solution [2] as it seems others are having similar issues and not finding answers.
