It's designed for POP3/IMAP for non-shell users, i.e. a closed-box system. the authentication _can_ be /etc/passwd-based, but typically you use a separate DB file to store the login info. -- Justin R.

I think that the easiest thing (not necesarily the best one) will be to write simple bashawk script to add users directly to passwd. The shell should be /bin/false - message that you can't get in (without invoking any real shells). Advantages: easy to perform, easy to manage Disadvantages: possible mess in passwd if you have pop3-only and normal users.
