I want to redirect messages with postfix if they are sent from a specific sender. The redirect should be visible in the To: field. For the redirect I tried to use this header_checks rule:
/^From:.*sender@example.com.*$/ REDIRECT new-target@example.com
This works and the message is redirected to new-target@example.com. But the To: header still points to target@example.com. How can I change the To: header as well?
To be more specific: The system is sending mails from different senders to different targets and I only want to redirect one of them.
Here are some typical combinations of from/to pairs that happen on this server:
From: sender@exmaple.com -> To: target@example.com
From: sender2@exmaple.com -> To: target@example.com
From: sender3@exmaple.com -> To: other@example.com
I only want to redirect sender@exmaple.com -> To: target@example.com to another target and change the To: field as well. The others should remain the same. How can I do this?
If I add another header_checks rule to match To: target@example.com then it will also change the To: field for sender2.
