Hi all,

Firstly, thanks for all your effort with this software. Much appreciated.

I am having a slight issues trying to enable reading of other users
mailboxes. The docs are a little sparse for those that aren't
mailadmin heros, I wonder if anyone could please help me see where I
am going wrong.

I would like to allow some users to list and read the mailboxes of
others. E.g: When User1 logs in, they are presented with a list of their own
folders, and those of User2, User3, etc to which they have (e.g.
read/list) access

I followed the instructions on the wiki (for Version 1.X)- there are
two concepts here: the form of a BDB file:

1. Grant some [e.g. list/read] access on a mailbox folder to a particular user
2. Enable the acl_shared_dict to allow dovecot to track (and display
   to IMAP clients) the folders to which they have access. This will take

/var/lib/dovecot/shared-mailboxes.db This file can only be updated by using the SETACL command. *This is
where I have the problem*. The SETACL command does nothing.

No matter how hard I try, I cannot get dovecot to update this file.
The only indication I have that the file exists and is readable by
dovecot is the disappearance from the logs of the line: No acl_shared_dict setting - shared mailbox listing is disabled So I can see that dovecot knows the file is there because it does not
complain any more.

The file is there (because I created it myself, although it is empty:
size = 0), and in a moment of weakness I made sure it could be updated
(this will be changed back!): ls -l /var/lib/dovecot/shared-mailboxes.db -rwxrwxrwx 1 dovecot dovecot 0 2012-10-30 12:27
/var/lib/dovecot/shared-mailboxes.db

But if I try to update the ACL, absolutely nothing happens: [ > command ] [ < reply ]

telnet localhost 143 < * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID
ENABLE STARTTLS AUTH=CRAM-MD5] Email server a login [User2] [pass]

CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH ACL

a SETACL Inbox [User 1] rl < a OK Setacl complete.

At this time, in the dovecot log (with debug enabled): 2012-10-30 13:55:24 IMAP([User2]): Info: Namespace : Using permissions
from /home/mailboxes/[domain]/[User1]: mode=0770 gid=-1 2012-10-30 13:55:24 IMAP([User2]): Info: acl vfile: reading file

/home/mailboxes/[domain]/[USer1]/dovecot-acl

Can anyone please help me track down what I'm doing wrong here?! It's
driving me mad! Thanks for your time if you've read this far!!
