[Dovecot] How to lock a user out?

[Kai Wang]

Hi,

We are considering to migrate to Dovecot. We can running uw-imap and 
have a local path which allow us to lock a user by creating a .lockdir 
directory in the user home directory and put our warning message to 
.lockdir/mbox. The locked user can still receive messages in ~/mbox. But 
can not access any messages except ~/.lockdir/mbox. I wonder if Dovecot 
has any similar feature which we can use to lock a user out without 
affecting the mail delivery?
