Zitat von Mikkel Bang <facebookman...@gmail.com>:
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?
There is no "ulimate email server" because it all depends...
Dropped: - postscreen: Looked into http://www.postfix.org/POSTSCREEN_README.html but couldn't really find anything concrete to add to my setup
If you are suspecting Spam-Bots hammering your server you really should use Postscreen. If your traffic is really low you can exclude it.
- 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
The delay is adjustable and there is a useful feature called automatic whitelist.
- opendkim+spf+dmarc: Advised against by the dudes in Freenode ##freebsd, saying its role in anti-spam protection is minimal
It might be useful when sending to Hotmail/Yahoo, but you can easily live without.
- 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)
Content Filter are heavy processing but used with tagging/folders can cut a lot more spam.
- spamdb+greytrapping: Not necessary if I'm already running dspam
Don't know at all
- mailscanner: Not necessary if I'm already running dspam
Mailscanner is not supported with Postfix (http://www.postfix.org/addon.html) Regards Andreas
