DNS blacklist filters overview
DNS blacklist filters are a new and powerful feature in Domino 6 and one of the more effective weapons against spam. With the DNS blacklist filters enabled, Domino will check inbound mail to see whether it originates from a mail server that is listed in one or more DNS blacklists (DNSBLs).
