Someone I think Adarsh was asking for a lightweight
anti spam solution. Maybe the attached is relevant.
Looks like you could use postfix.

I am looking for the best possible solution in order to setup a High
availability mail cluster using FreeBSD (smtp/imap/pop server with 1000
accounts).
Selected software are as followed :
-----------------------------------
- Postfix
- Amavisd-new
- SpamAssassin
- Courier Imap
- DCC-DCCD
- Clamav
- a web mail (not yet selected but probably horde)
The idea is to offer a simple and very efficient solution in order for the
server to have a 100% uptime under any circumstances.
I would like (if possible) to stick to software available in the ports (for
ease of maintenance).
I was first thinking about using Linux-HA aka. "heartbeat" and syncing the
two boxes using rsync ?
What other solution would you think of ?
Can't really help with the HA aspect, but I'd take a look at:
http://www.freebsd.org/cgi/url.cgi?ports/mail/postfix-policyd-weight/pkg-descr
"Policyd-weight is (as the name says) a weighted policyd for Postfix.
It uses HELO, MAIL FROM and the MTA IP address for scoring their
correctness. It also uses definable DNSBLs and RHSBLs in a scored
fashion."
I've been using that instead of spamassassin (which can be a memory hog)
and very little spam makes it through. It's nice in that it doesn't even
have to accept the message body to do it's thing.
Also, consider, clamsmtp
http://www.freebsd.org/cgi/url.cgi?ports/security/clamsmtp/pkg-descr
for tying clamav into postfix without having ot use amavisd...
And lastly, you might take a look at roundcube for webmail...
