Hi List...I successfully run a QMT mailserver since 2 years ago. 1
month ago I had a problem. For some reason my delivery was very slow
(approx 30 sec). I found that the problem was Spamhaus checking. Due
to my stupidity I deleted /var/qmail/control/simcontrol and
/var/qmail/control/blacklists and /var/qmail/control/badmailfrom.
Since that moment I am receiving tons of spam mail
Is there someone can help me hardening the sistem fighting spam ?
Replace those files.
Run sa-update to update your spamassassin rules, and add more rules.
You could also look at Spamdyke and implement the greylisting feature.
