Need help with mailbox error.

Hi everybody.

I am hoping someone can help me with a problem I have with Postfix (v2.3.3) and Cyrus (v2.3.7-Invoca-RPM-2.3.7-1.1.el5) running on RHEL5.1. We are trying to migrate from a Debian Sarge system to the RHEL5.1 server.

There seems to be a problem when cyrus/lmtpunix gets a mail and tries to save it to a mailbox. I get the following error in maillog: 
May 15 10:49:05 mail1 lmtpunix[25257]: verify_user(user.username) failed: Mailbox does not exist.
I will include a longer paste further down. 

I have created the mailbox with cyradm.
[root at mail1]# cyradm localhost
IMAP Password:
localhost.localdomain> lm
username (\HasNoChildren)
root (\HasNoChildren)
user^username (\HasNoChildren)
user^root (\HasNoChildren)
userusername (\HasNoChildren)
userroot (\HasNoChildren)
localhost.localdomain>


I am probably missing something obvious but I can't for the life of me understand what.
We are using multiple domains in postfix which seems to work fine as the correct username is forwarded to the lmtpunix daemon.
