It would be great to have a HOWTO in the wiki, on how to restrict
services by username in dovecot, so some users are allowed IMAP
and others not allowed.
As concerns restricting users by IP, I believe that is a bad idea.
It's almost a useless idea, imnsho, because they can connect from
another IP.
It's easy to restrict services by IP using a firewall or by using
inetd.
