Dovecot Namespace with system and virtual users

[Jim Seymour <s93763@bellsouth.net>]

Hi,

Been wrestling with this for a couple of weekends now to no avail.
Google searches have provided incomplete information for me to solve
this. I want to be able to receive and retrieve mail from system users
using mbox format with pam for authentication and virtual users using
maildir format with mysql authentication. This system was working
correctly for system users prior to the addition of virtual users. I
followed the http://workaround.org/articles/ispmail-etch/#abstract
to set up the postfix, dovecot with mysql authentication. It does not
really cover using two different authentication methods though. Pop or
imap access does not matter to me if I can only get it to work with one
method.

The error the way it is currently set up is that the users mailbox will
not update (new mail will not display-the old mail in that mailbox is
readable). Logging in and out makes no difference either. The folders in
~/Mail/ that contain the subscribed folders work perfectly. Output of
dovecot -n:

Thanks for any and all help,
