Hi Henrik,

You evidently have postmaster aliased to root in /etc/mail/aliases (a
common; nay default alias in sendmail), so sendmail will never try to
deliver to postmaster, but only to root (as evidenced by the "(expanded
from: <postmaster at htc.troeng.com>)" line).

Either change the alias to send it to the correct user (don't forget to
re-build the aliases database!), or delete it (ditto on the "don't
forget") and let it go to the postmaster mailbox you have created.

Mike.

I'm sorry to say, but this has nothing to do with my problem. I have the
same problem with other usernames also.. So this is not just a postmaster
problem. 
To be sure, I did test what you wrote, it made no difference...

What can be wrong? 

I did check the imapd.log file and got some output:

about to exec /usr/cyrus/bin/lmtpd
executed
accepted  connection
lmtp connection preauth'd as postman
append_check() of 'user.postmaster' failed (Mailbox does not exist)
