Bounce Mail for _known_ recipient

[nikro]

Hi,

I have a mailuser "web13_callback" with the e-mail address "callback@domain.tld" and the alias "test@domain.tld". The servers fqdn is "server1.domain.tld".

I have no problems to receive mails on the "normal" way from outside. It's also no problem to write an e-mail as root with "mailx callback@domain.tld".
But when I redirect root's mails to callback@domain.tld in the /etc/aliases then Postfix bounces it:

Jan 13 10:52:05 srv002 postfix/local[20613]: 356AA51836E: to=<callback@domain.tld>, orig_to=<root>, relay=local, delay=0.1, delays=0.09/0/0/0.01, dsn=5.1.1, status=bounced (unknown user: "callback")

I don't know why it cuts off the domain part, but I tried to forward root's mails to "test@domains.tld" what works:

Jan 13 11:23:35 srv002 postfix/local[24320]: EBAD351836E: to=<test@domain.tld>, orig_to=<root>, relay=local, delay=0.09, delays=0.08/0.01/0/0, dsn=2.0.0, status=sent (delivered to maildir)

I know I can use "web13_callback" in the /etc/aliases and I do. But I propose to fix this buggy behavior.


Greetings!
