I can't manage to implement a new request for mail routing.
Our mail domain is listed in "virtual_alias_domains". All mail addresses and the respective target mail addresses are listed in the file defined in "virtual_alias_maps". An address rewriting is therefore carried out, whereby the domain used in the target mail addresses is not listed in "virtual_alias_domains". A transport rule in "transport_maps" defines the server (e.g. Exchange) to which the final mail delivery should be made. In simple terms, the configuration looks like this: /etc/postfix/main.cf: virtual_alias_domains = example.com virtual_alias_maps = hash:/etc/postfix/virtual transport_maps = hash:/etc/postfix/transport /etc/postfix/virtual: us...@example.com user1@exchange /etc/postfix/transport: exchange smtp:[excha...@example.com] This setup has been used in this form for many years. The new requirement is to route some mail addresses of the mail domain without address rewriting. I am aware that this could in principle be realized via a rule in "transport_maps", e.g: /etc/postfix/transport: us...@example.com smtp:[some_other_destination] But then the mail is rejected in the SMTP handshake as soon as it is sent: Recipient address rejected: User unknown in virtual alias table I have tried to list the mail address in virtual_alias_maps with a dummy entry so that no address rewriting takes place. The destination is therefore identical to the original mail address: /etc/postfix/virtual: us...@example.com us...@example.com Fortunately, this does not create a loop. The mail is now also accepted via SMTP, but I receive a bounce mail with the following content <us...@example.com> : User unknown in virtual alias table Dispensing with virtual_alias_maps and only routing via transport_maps (and possibly relay_domains) would certainly be a sensible option. However, this cannot be changed in a hurry because a number of scripts are still attached to it that process these maps. How could this be solved in the existing configuration with virtual_alias_maps?
