Everytime when I run update.php (with "Reconfigure Services" set to "yes") I get errors with my email server.
postfix/local: AF94416A0E2: to=<firstname.lastname@example.org>, orig_to=<email@example.com>, relay=local, delay=1.2, delays=0.01/0.06/0/1.2, dsn=5.1.1, status=bounced (unknown user: "ich")
In mail.log I found:
postfix/trivial-rewrite: warning: do not list domain xxx.net in BOTH mydestination and virtual_mailbox_domains
I don't know the reason but my domain appear into mydestination
(in /etc/postfix/main.cf) after the update process, then I get this error.
The solution is easy but how can I update without this issue in the future?
