[Dovecot] restricted dovecot conf

[Goran]

Hi all,

I have a simple but well running dovecot configuration attached below.

Now I want to change some things. What I need is an IMAP-Server which
restricts the user to the following:

- no folder createable
- no messages deleteable

How to get what I want?

My Version: Debian x86 Squeeze, Dovecot 1:1.2.15-7.

Many thanks in advance!

Goran
