Hi Paul,

The soulution may be - as Rudy already wrote - the recipient delimiter 
setting (in case you use deliver) or wrong permissions in your Cyrus 
setup - if the posting user (Postfix is just a user to Cyrus, too) has 
no permission to post messages to user.paul.postbank at, it 
will fall back to user.paul@ in order not to fail delivery completely. 
So make sure, the user you use for delivery has post permissions (I 
think lmtpd writes the username in the logs, so have a look there).
