I started blocking connections to my mail server from servers who don't
have DNS and my vpopmail and qmailadmin list traffic stopped.
How much actual SPAM did your "now-misconfigured mailserver" actually block
with this tactic during that time? Before anyone flames me, consider that
this is a serious question and I am very interested in the answer.
Thanks. Rick Up
