My How-to doesn't cover Courier because it has it's own special mailbox
format and does not use normal Linux users.  Dovecot does use normal
Linux users and the standard maildir format.

My solution specifically is not a mysql / courier solution.  It is a
Dovecot / IMAP / SquirrelMail w/o virtual domains.
