I'm trying to configure "the ultimate email server" for this webapp that needs to send and receive / forward emails to and from thousands of users.
But with so many people recommending so many different tools, it gets hard to come to a conclusion. Looks like I'm finally arriving at this though: postfix (postfix-anti-UCE.txt) + dspam - what do you guys think? Dropped: - postscreen: Looked into http://www.postfix.org/POSTSCREEN_README.html but couldn't really find anything concrete to add to my setup - postgrey: Advised against by the dudes in Freenode #postfix - I've tried it before and it was really effective, but I don't think my users will like that 5 minute delay - opendkim+spf+dmarc: Advised against by the dudes in Freenode ##freebsd, saying its role in anti-spam protection is minimal - spamassassin: Too old, too huge and too hard to set up (but maybe those who advised against it had more against Perl than anything else) - spamdb+greytrapping: Not necessary if I'm already running dspam - mailscanner: Not necessary if I'm already running dspam Mikkel
