[Dovecot] Newbie question: configuration for virtual users

Hi!

I'm looking forward to deploying dovecot as an IMAP server. I did some research into the various options and it looks like dovecot is the right daemon for me. I'll be using it with Exim.

I am running a few tens of users on my server, most of them small numbers of people part of a small company, e.g. example.com.

At present I have exim delivering to mbox in each virtual user's mail folder. So, for chris, john and mandy @ example.com, I have

/home/example/Mail/
    chris
    john
    mandy

All of the users in example.com run under the same uid and gid (example). I like to separate these 'virtual' users from the real system users for security reasons. I presently serve up these mboxes via teapop, which allows for per-domain configuration. I couldn't find a similar setup after a cursory read of the config file examples on the dovecot website.

I'd like some advice on how to support different non-system users under dovecot, ideally storing mail in a similar configuration to above, except (presumably?) that the user files will be under each user name? Thus:

/home/example/Mail/
    chris/
    john/
    mandy/

I may use postgresql to store user configuration data if appropriate.

Advice gratefully received. Rory
