Tech Reporter Pursues Spammer 183
girish writes "Technology reporter extrordinaire, Mike Wendland, is at it again tracking down spammers. Wendland conducted the infamous interview with Alan Ralsky, the alleged mega-spammer, a few years ago. That article spawned a lively discussion on Slashdot and eventually resulted in hundreds of pieces of junk postal mail flooding Ralsky's million-dollar home. Now Wendland is using a new tool from a service called Project Honey Pot to track email address harvesters. He posted on his technology blog this morning about catching a company that is holding itself out as a legitimate bulk mailer, but appears in fact to be sending to harvested addresses and conducting on the side some other seemingly seedy businesses. Interesting stuff."

I get massively less spam than you - around 300 a day, though most of it gets stopped dead at the mail gateway by ordb.org and dsbl.org checks. I get about 100 or so spam actually delivered, and SA (set to be pretty forgiving) filters out all but 10 or so per day. I don't envy being in your position.
Viruses, however, are another story. I haven't seen one in six months - it's fantastic. A combination of some postfix rules and ClamAV on the internal (sendmail) mail server did the trick. If you run postfix at your mail gateway, you can get it to check incoming mail for suspicious filenames before it even accepts the mail: (note: the regexp and message are all on one line, though I should move to an extended regex and split it up).
*blam*. There goes 99% of your incoming virus mail. ClamAV gets the rest, so I just don't get viruses anymore. Best of all, you're not generating bounces for virues, you're rejecting them instantly - so unless they're using some dumb bastard to relay, there won't be any mess of bounces to falsified addreses to worry about.
What about the new waves of self-zipping viruses, you ask? Yeah, that's an issue. I cheat and quarantine all zip files. I rarely have to retrieve one, and it's well worth the saved fuss.
As for mail programs, I'm happily using Evolution with IMAP over a 512k/256k effective link to work's Cyrus IMAPd server (all this stuff is set up for work). It works great, and I'm able to use 20,000 message mailboxes without noticable stress. Sieve (the cyrus IMAPd filter language) filters everything into the right mailboxes server-side, so if I'm in a hurry I just read my (always small and managable) INBOX without worrying about my lists.* folders, the (server-side filtered) Junk folder, or anything else.
