Summary: Only
mails are accepted over
incomming SMTP sessions so far in this week.
Almost all of mails are from SPAMmers.
They come from all over the world as the map bellow shows, maybe via bot nets.
Their SMTP sessions are blocked effectively by DeleGate as a
SMTP server
(with SMTPCONF=reject),
and then filtered based on their message contents (as To, From,
Subject, Content-Type, text in body or so) by
SMTPGATE.
