I have an smtp server that I use as smtp relay for some internal mail
server and as smtp authenticate for some users.
I have the enabled sender IPs in network_table
I have the enabled users as system users in passwd/shadow
Inserting my local domains (hosted in another internal server), in the
transport files with the syntax:
domain1.it smtp:1.2.3.4:2525
domain2.it smtp:1.2.3.4:2525
....
I have mail sent using this server routed directly to the final
destination server.
All working without problems.
I want configure the MX record for some domains to point directly to this
server instead of the standard mail filtering server and then mail
forwarded directly to the final destination server.
Tried some settings from the docs without success.
I always have the "Relay Denied" result:
Jan 23 00:11:34 auth postfix/smtpd[188544]: NOQUEUE: reject: RCPT from
wp-host1.xyz.com[4.3.2.1]: 554 5.7.1 <f...@dom-redir.it>: Relay
access denied; from=<r...@wp-host1.xyz.com> to=<f...@dom-redir.it>
proto=ESMTP helo=<wp-host1.xyz.com>
Tried to insert it in relay_domains without result
Played with some settings without result.
I suppose I am missing something trivial, but I can't see what.
Any hints appreciated.
Thanks, B.
