Hi all, I'm having trouble getting a new Postfix/Dovecot server up and running.

I'm trying to run v1.0.3, using MySQL tables setup list postfix admin.
This is a RHEL5 server.
Getting this error
tail /var/log/dovecot/dovecot-deliver.log
deliver(none at example.com): Sep 04 19:44:15 Fatal: setgid(12) failed:
Operation not permitted
That 12 being my vmail user.

I'm not exactly sure what's trying to setgid, nor how to fix it, any
ideas would be appreciated.
