Mail fixed. Woot.

Ok, so the mail issue was actually a firewall issue, but in the troubleshooting, I did a clean reinstall of exim4.

Mail seems to be really happy after fully reconfiguring it. Virus scanning seems to mostly be working, though there were 6 failures lastnight. I think maybe a rate limit issue. Will look into it..

Procmail has been disabled since exim has good filtering in .forward files and procmail seemed to be not happy on my server.

Spam scanning seems to be working, but I don't have bayesian filtering enabled. It's too heavy for my little ole mail server. Everyone who doesn't have an external forward set up has it set to automatically send spam as tagged by spamassassin to go to their junk mail folder automatically.


This means that spammers who do not retry temporary rejection will never be received. Since the premise of spamming is to use as little time on their end as possible, this should remove a good chunk of their traffic without having to spend much CPU time on it. This should not affect messages sent by normal, valid, full-time mail servers, which some spammers use. It's not perfect, but it's a cheap way to cut spam counts.
