Hi! I host a number of domains on a box and I recently added one which has resulted in that domain literally being HAMMERED by some spammer sending spam to every kind of bogus e-mail address for this new domain you can think of.
The server is a Linux box running RedHat 9 with Qmail (netqmail-1.05)/Vpopmail 5.4.9/Courier-IMAP 4.1.0 w/ SpamAssassin 3.1.1 (perl 5.8.8)/ClamAV 0.88.1. The incoming messages are being sent to addresses like: [EMAIL PROTECTED] and sometimes there will be other addresses CC'd on the message. The CC'd addresses are in other domains and mainly in the ".ru" domain. For a while, Qmail was bouncing the messages and since then I've changed it to have the messages delivered to the postmaster account. So, the postmaster for mydomain.com is geting flooded with spam addressed to bogus messages in the mydomain.com domain. What can I do to stop this? The performance of the server doesn't seem to be impacted (load avg is well below 1 and hangs out below 0.5) so I'm not worried about that as much as getting miffed at the constant influx of spam. SpamAssassin is flagging most of the messages as spam, with scores well over the default threshold of 5.0. I'm seeing scores in the 6+ range on the low end and in the 20+ range on the high end. Help?!?!?!?!?!!? :) I'm using the SpamAssassin defaults and I upgraded from 3.1.0 to 3.1.1 via CPAN a week and a half ago. Thanks in advance for your time and assistance! Peace... Tom
