Rewriting all emails sent by mailcow with sender_canonical_maps

[ro78]

Hi,

Just FYI, I'm using this docker container with mailcow.

In the docs, it's required to add this line:
sender_canonical_maps = socketmap:inet:172.22.1.42:10003:forward

I had to disable it, because any email sent by my accounts was rewritten on Return-Path part to my SRS redirect domain. Not sure why it was added to the documentation.

Disabling this line allows me to send emails normally, and still receive redirected emails through SRS for real SRS aliases.

Best regards,
Romain
