I’m not shure about the wording. Maybe bouncing is the right word.
Problem is, that a local user did send a message to a non-existing domain. Now I expected that postfix will send the message back to the sender. Isn’t this default behavior? And if not, what have I to do to get this working?
If someone’s interesseted in my postfix configuration: Pastebin (because it’s to large to post here).
The problem in simple steps:
- email@example.com sends a message via mail.mydomain.org to firstname.lastname@example.org
- Mail stays in postfix’ mailqueue now for over 5 days.
- Notify the sender (email@example.com) that message couldn’t get delivered.
The parameter you want to look at is
It seems that in your configuration it’s set to 2 days, which is kind of low. Perhaps you changed it after this issue occurred? Or did you remember to reload Postfix after changing it?
