I’m really annoyed as I’ve now had over 600(!) spams from the same idiot. Well, I say ‘had’, they’ve got as far as my mail filters but have then been automatically tagged as spam: but it’s still annoying they got that far. I tried to change my server settings so that they couldn’t even that that far (IP blocking etc), but unfortunately they relayed them through my secondary MX (ie my ‘backup mailserver’) which is now passing them to their proper destination (ie my primary mailserver). Obviously, I can’t block that IP as then all mail that does end up on by secondary MX won’t reach me – so grr. (Ok, a few were directed at my primary MX, but by looks of things it’s mainly my secondary one that’s had the brunt of the spam)
I have installed SpamAssassin on the server, but I’ve still got to correctly configure Qmail to use it (currently I’m relying on MailWasher to do all my spam filtering – mainly because I’ve got a domain which cannot, for historical reasons, that cannot support server-side filtering).
