Hi,
thanks for reply. We thought that we have to copy existing
"aliases" file from imap server to incoming MX. If we reject an
emailduring smtp communication, we won't "relay" spam to victim. Am I
right ?
Best regards

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)
You can have "reject_unverified_recipient" on the MX to check the IMAP
server if the email address exists before accepting it.
HTH,
Mikael
