New Spam Filters

       We will be implementing some new spam filtering capabilities from Spamhaus that I hope will increase the effectiveness of our spam filters.

     These consist of a domain reputation black list and an IP based system that will prevent our mail server from being used by spam botnets when credentials are compromised which should reduce the incentive for same.

     The existing blacklists incorporated in SpamAssassin are all IP based, but spamassassin 3.3.1 made available domain based black lists and SpamHaus has incorporated these.  We will be doing so shortly.  As before these won’t outright reject but rather divert mail identified as spam into your spam folder.
