Hello List

I am running a Cyrus IMAP that needs to be replaced.

Geting a Dovecot IMAP up and running was surprisingly simple. My configuration is close to Johnny Chaddas Howto at http://johnny.chadda.se/2007/04/15/mail-server-howto-postfix-and-dovecot-wit...

Its a Dovecot 1.1.10 on FreeBSD 6.4

Anyway, while basic setup was easy, i stuck in a couple of details like quota, managesieve, etc. Actual major problem and showstoper is understanding the ACLs the confuses me. So i need a hint to be guided in the right direction.

What i need is a scenario, where user1 can get (for example) full access to the folders of user2, read-only access to user3 etc. A real world example: Secretary has full access to the mailfolders of her boss, boss has read-only acces to the sales-department folder.

My questions:

1. is the possible?
2. can it be done with dovecot-acl files?
3. Namespaces: is it enough to have the private namespace for the job or do i need another namespace?
4. if yes, how should this namespace look like?

Thanks for the help Achim
