Ok, I thought I tested accessing the mailbox afterwards, too - but I probably had not. I have a more general problem now: shared mailboxes from any "non-INBOX" namespace are not available to other users. That's not only with virtual or imapc namespaces, but also tested with two Maildir ones: namespace personal { inbox = yes location = maildir:~/Maildir prefix = INBOX. type = private } namespace second { inbox = no location = maildir:~/Maildir2 prefix = INBOX.second. type = private } namespace others { type = shared separator = . prefix = INBOX.shared.%%u. location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u #location = maildir:/home/%%n/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = children } [...] I can as user1 SETACL INBOX.second.box ~user1/Maildir2/dovecot-acl-list contains "1316082286 box" ~user1/Maildir2/.box/dovecot-acl contains "user=testuser lrs" (as does ~user1/Maildir/.in2007/dovecot-acl) The shared mailboxes dict contains shared/shared-boxes/user/testuser/user1 1 But - as testuser - 0 list "" "*" * LIST (\HasChildren) "."

[Dovecot] Dsync Permissions Issue

Greetings, I recently upgraded Dovecot from 1.2 to 2.0.14, for purposes of using Dsync to migrate emails from one server to another. I'm using MySQL for authentication.

[Dovecot] Shared folder not listing
by Tom Clark 16 Sep '11

16 Sep '11

Hi Timo, I've got a weird problem on our dovecot. We're trying to setup private shared folder access. I have 2 users. tom(a)mailbox.com and system(a)mailbox.com. I have set the ACL's on all the folders (and subfolders) on system(a)mailbox.com. However, I'm not getting any of them listed when I check tom(a)mailbox.com <mailto:tom@mailbox.com's> 's IMAP folders. Our configuration is below (we're migrating from Courier hence the INBOX.): In 10-mail.conf: namespace { type = private prefix = INBOX. separator = . inbox = yes list = yes hidden = yes } namespace { type = shared separator = . prefix = INBOX.Shared.%%u location = maildir:%%h/Maildir:INDEX=~/Maildir/Shared/%%u subscriptions = no list = children } mail_plugins = acl protocol imap { mail_plugins = $mail_plugins imap_acl } In 90-acl.conf: plugin { #acl = vfile:/etc/dovecot/acls:cache_secs=300 acl = vfile } # To let users LIST mailboxes shared by other users, Dovecot needs a # shared mailbox dictionary. For example: plugin { acl_shared_dict = file:/var/vpopmail/domains/%d/shared-mailboxes } Have I missed anthing!?!? Thanks in advance! Tom
