Quickly skimming over it, the answer there seemed correct to me. Therefore, what's lacking is your description of the problem, "But it did not worked for me." That does not show us any logs, nor does it tell us what you did. Perhaps you're missing the idea of complete separation of submission from inbound MX mail. The way this is done is to require your users to use submission (port 587) and SASL AUTH, and do not offer nor accept AUTH on port 25's smtpd. Then their mail, "outgoing", gets the receive_override_options or the alternate cleanup_service_name. The person answering the serverfault question understood this, but the one who asked it probably did not. To proceed, we'll need the information as provided in the list welcome message, which can be seen also here: http://www.postfix.org/DEBUG_README.html#mail -- http://rob0.nodns4.us/ Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:
