Hello to all, This is my first post, so bare with me I have a postfix relay server in front of a Windows Exchange Cluster. I have a problem with incoming mails that the sender belongs to a subdomain of the one postfix serves. To be more precise, lets say that my domain is "domain.com" and postfix works ok with all incoming and outgoing emails. I have a sender named "[email protected]" that is not located inside my lan but somewhere at the internet. When this user sends emails to "[email protected]", the emails pass through, but with MAIL FROM changed to "[email protected]". On MS Exchange logs, all emails are from [email protected], no reference to the subdomain. Also, the /var/log/maillog says: I can't seem to find something in the configuration that rewrites the mail from addresses based on some policy to [email protected]. Transport table has entries: domain.com smtp:[1.2.3.4] *.domain.com smtp:[1.2.3.4] Any help is greatly appreciated, Nick
Can you post your main.cf? Are you sure that it is Postfix that rewrites the sender address and not Exchange?
