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... http://roundcube.net/
