General instructions for using a policy service with postfix can be found here: http://www.postfix.org/SMTPD_POLICY_README.html A (likely incomplete) list of third-party policy servers can be found here: http://www.postfix.org/addon.html#policy I don't have a specific recommendation, but you'll probably want one with SQL support if you have a large number of aliases to protect. -- Noel Jones
