Thanks for the responses!

Sorry if I reply to every single one in this email however, I am using
Gmail's awful Web UI so I don't really have much control over what I'm

To start with the reason I'm not using LDAP is because I couldn't find
enough information on how to set it up! I did post here a couple of
times but got no responses...... so I figured it was something that
people either didn't know or found trivial.

I'll take a look at the above config for Maildir format as briefly
playing around with mbox it seems that folders on the / root (parent)
IMAP directory are stored separately. It may be better if everything
got stored under the Maildir heading.... I've previously **only** ever
worked with Maildir but I was told that there are some benefits to
mbox which is why I decided to try to use it here!
