Good morning,
our outgoing smtp server gets into a backscatter blacklist. When I
checked my logs, there were only one mailer daemon email to some
server in the time that is mentioned on the backscatter web.
In all servers in the way of the email (incoming MX->antispam
server-> our imap server) has unknown_local_recipient_reject_code = 550.
What else could I do ? There could be one thing - incoming MX
accept all emails for our domain, he doesn't know our aliases. The
mail is send to antispam and when antispam wanna sent the email to
imap server and the target email address doesn't exists, it has 550
error and it is send away by our antispam server (it is our outgoing
server).
So, is this all wrong ? We decided to have more servers because of
loading reasons (we've daily up to 15 000 emails, but there were a 60
000 peak)
Thanks and best regards
J.Karliak.
