for postgrey implementation I would recommend policyd (we use v1). it has such features as whitelisting (by ip, by sender). so you can whitelist big mail players (gmail, facebook and etc). blacklisting (by ip, by sender). automatic blacklisting and etc. but this system also requires monitoring. I have written script which checks blacklisted hosts and parses maillog to check what senders to which recipients this host was trying to send mail. only some hosts got false blacklisted. and after few months it did not got any false blacklisted hosts. even after few years we got complains about that we block some hosts, and after check of logs it was clear that those hosts sends "newsletters" from lot of companies. for antispam I also can recommend dspam, but it requires that every user would learn system which mail is spam and which not. _______________________________________________ DBmail mailing list [email protected] http://mailman.fastxs.nl/cgi-bin/mailman/listinfo/dbmail
