[Dovecot] Deliver - Virtual users

[Tobias Balle-Petersen]

Hello...

I have dovecot 1.0.10 running with users in an LDAP database. Things are 
working as they should with IMAP.

However, I can't seem to make deliver w. postfix work they way I want.

My problems are:
Mail to users who do not exist in LDAP or locally are accepted and 
mailfolders are created. I want mail to users that do not exist in LDAP 
or locally to be rejected.

Mail is delivered to users even though they are over quota.



Below I have included a bit of my log. This is what I see when
sending a mail to an existing user. I don't understand the part that says:
dovecot: auth(default): passwd(tbp at kontrapunkt.dk): lookup

In my database users are stored as usernames without domains. Deliver 
seems to lookup the name with domain?
The lookup ends with "unknown user". Then I wonder, why is the mail 
delivered if the user is unknown?

I have included the "protocol lda" part from my dovecot.conf and the 
result of "dovecot -n".


Can someone help me get this sorted out?


Thanks,
Tobias
