I have setup Postfix as part of my ISPConfig implementation. It should just forward all mail. Clients should be able to define a new alias and receive mail on a different e-mail address, using ISPConfig.

Example: A mail sent to user1@domain1.com on my ISPConfig server should be forwarded to external mailbox user2@domain2.com This works fine but one important thing.

When opening the mailbox for user2@domain2.com I see the mail with the original sender name, and the original recipient name, i.e. user1@domain1.com

I have tried the forward function and the send copy function on a mailbox in ISPConfig. Both cases show the original recipient user1@domain.com instead of the final recipient user2@domain2.com, as it would when I manually forward an e-mail.

Can this be achieved without having to maintain a list for each entry?

You are new to email and apparently don't know the difference between the MAIL TO: envelope recipient and any To: headers in the message itself.

These are not the same; see RFC5321 for details.


Simply set enable_original_recipient = no in your /etc/postfix/main.cf file. This disables the Original-Recipient headers being added to your outgoing email.
