I've setup 2 different IMAP accounts in my new ZD installation.
One is a RHEL-5 Dovecot and the other is RHEL-6 Dovecot, both
using Maildir message storage. AFAIK, both setup identically.
The RHEL-5 account shows up fine -- no problems.
The RHEL-6 account shows ALL email in the "inbox".
Any idea why that might be? The config files for Dovecot were
moved around in RHEL-6, but I don't think the variables that can
be setup changed.
