postfix redirecting incoming messages to local root user?

stefan_o

I've got a really weird problem:
If I send an email to for example mail@mydomain.de (that address is a user in my grommunio). But postfix decides it needs to redirect that mail to root:
Feb 03 14:32:54 GrommunioContainer postfix/local[137375]: EA4B9318ACE: to=<root@mydomain.de>, orig_to=<mail@mydomain.de>, relay=local, delay=0.08, delays=0.07/0/0/0, dsn=2.0.0, status=sent (delivered to mailbox)
And sure enough, the mail is now in the /var/spool/mail/root file. What is going on here? Why is the mail not processed by grommunio?

I found why it is redirected to root: There is /etc/aliases that redirects mailto postmaster and postmaster to root. I removed that line and now... the mails end up in /var/spool/mail/mail. This is postfix as it came with the appliance, why is it configured to not use grommunio?

I solved it:
There was a warning:
warning: do not list domain mydomain.de in BOTH mydestination and virtual_mailbox_domains
I removed it from mydestination and now it seems to work. It seems the setup process created a broken postfix configuration.
