This appears to be the same problem I had last week, and which was 
solved. As far as I understood, authentication with sasl is completely 
seperate from mailaccounts, you can have users authenticate yet have no 
mail account.

So you may be able to authenticate but there is not mailbox for that 
user. How can that happen? Well, if you have virtual domains enabled, it 
is posible to authenticate and end up in the wrong namespace.

The clue is actually there in the documentation (I found after being 
clueless a week): Cyrus does reverse lookup on the ip that recieves the 
connection and uses that domain as the domain part to create a fully 
qualified user id. If reverse hostlookup gives something else than it 
should, you end up the wrong place.

There are two ways of solving this: use fully qualified userid, eg. 
user at example.tld (you can force this as required by setting
virtdomains: userid) or make reverse lookup return the domain correctly 
(eg add entries in the hosts file).

See the install-virtdomains file for the details.

Cheers, Erik
