Après avoir modifié main.cf, vous devez utiliser la commande:
postfix reload
I used systemctl reload postfix and even systemctl restart postfix.
I just tried postfix reload for comprehensiveness, but nope, same issue.
I can’t help you out directly, but I had similar errors in this case:
- My user is member of a group
- The group has mail aliases
- Emails sent to the group mail alias are forwarded (also) to my mailbox
- Replying to those emails gave the error
Sender address rejected: not owned by user
No user is part of any group in my case (well, except “all_users”).
