[Dovecot] LDA postfix + deliver, problem lookup, accepting email for everyone

[Sylvain Viart]

Hi,

I'm setting up dovecot pop3 deamon for a small set of mailbox.

I want to be able to set a small set of mailbox simply, so I've used 
"passdb passwd-file" + virtual mailboxes with "userdb static".
My problem is that it seems that postfix accept and create mailbox for 
every address I post. It is configured to use local delivery through 
dovecot's deliver.

How do I force deliver to retrun an error if the destination is not 
defined in the passwd-file?
The doc said that "userdb static" should do a lookup automatically. But 
no luke for me.
Is it really a deliver problem, or a postfix configuration problem?

Any, hint?

Regards,
Sylvain.
