[Dovecot] What is your dovecot setup?

[Timothy Murphy]

I'd be really grateful if someone running a dovecot IMAP (or IMAPS) server
could tell me exactly how their email folders are arranged.

What is the mail_location setting in /etc/dovecot.conf ?

What are the directories (or some of them) containing mail messages?

Does the client see an inbox folder?
If so, what directory on the server contains these email messages?
