I recieved an email from new reader Emily asking about Alaksandr, the Russian sendmail spambot that was plaguing me for months. It seems that Emily is having to deal with Alaksandr and asked me for some help, having read my posts detailing the problem.
There wasn't much I could say. “Aleksandr” only went away once I removed the email accounts he was spamming, and a check of my logs showed it's no longer showing up here. But it appears to still be an issue for others. Emily and I still have no idea why someone would spend the time and effort to send such spams. I wish I had answers.
