Can I get a show of hands for how people are running qpsmtpd? Specifically:
1) tcpserver running a) ./qpsmtpd directly
qpsmtpd directly. tcpserver uses a perm-blocklist I've built with a mysql backend of repeat offenders and those who have hit spamtraps.
6) What is your load (messages per day)?
I have around 1400 mailboxes. Over the past 24 hours (or so) qpsmtpd queued 7825 messages, while tcpserver denied 5315 permanently listed connections, and I had 24384 550 errors. Of the 550's, 24289 were blocklists, early_talkers, invalid users, invalid domains, joe-job bounces, and other RFC violations.
I hate to think that over 65% of our email would be spam if it were all allowed through.
Machine: Compaq ProLiant DL-380 (G2?) Dual PIII 1.2Ghz with 1GB RAM 70GB allocated to mail users
Load average varies from 1.x to 4.x (it's also doing lots of office stuff on the side). I've now set a iptables connection limit for hosts outside of our network to around 3 or 4. This should help against runaway servers that like to open 20 connections (happened this morning).
