[Dovecot] Shared mailbox not showing in list
by Tom Clark 08 Jul '11

08 Jul '11

I've setup a shared folder on my server which isn't showing in the list command for the user it's shared with. Can someone help? I have done everything correctly I believe. The user sharing their mailbox is support@, while I'm the user being shared with, tom@ namespace { type = shared separator = . prefix = 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 } plugin { acl = vfile } # Support for multiple domains plugin { acl_shared_dict = file:/var/vpopmail/domains/%d/shared-mailboxes } This what is in the dict file says: shared/shared-boxes/user/tom@mailbox.com/support@mailbox.com When running a GETACL as support(a)mailbox.com I get: 3 getacl Support * ACL "Support" "tom(a)mailbox.com" lr "support(a)mailbox.com" lrwstipekxacd 3 OK Getacl completed. However when I do a LIST "" * as tom(a)mailbox.com It doesn't have any mention of the Shared maildir. * LIST (\HasChildren) "." "Sent" * LIST (\HasNoChildren) "."

[Dovecot] Trash handling?
by Mason Loring Bliss 07 Jul '11

07 Jul '11

Hello, all. I've recently switched over to Dovecot from a long stretch of using Courier IMAP, and there's one thing I don't have working that I'd quite like. With Courier I had a magic trash folder in which things I deleted would live for a specified amount of time, after which they'd be deleted. I see how to get the expiry behaviour I want, but not the magic saving-to-mailbox functionality. lazy_expunge looks similar but not precisely what I want. Is there a default way to get expunged messages moved to a different mailbox but not a different namespace? Thanks in advance for clues. -- Mason Loring Bliss mason(a)blisses.org Ewige Blumenkraft!

[Dovecot] passdb/userdb via UNIX socket?
by Peter Mogensen 07 Jul '11

07 Jul '11

Hi, I've been running some performance tests - especially delivery (LDA and LMTP) and it seems there's room for improvement. At least it would be nice to get rid of the fork() and pipe to deliver LDA and the fork of the checkpasswd script for userdb lookup. I've tried LMTP to not fork deliver (*), but checkpasswd still takes time (ok, maybe because it's written on perl as of now). But I was wondering, why there's no passdb/userdb plugin for talking to a local authentication daemon over a UNIX socket? Have I missed something? Is there a thirdparty patch for this? /Peter *: Using Postfix "virtual" LDA seems much faster than asking Postfix to pipe data to "deliver". ... but then of course, I get no dovecot indexing by the LDA.

[Dovecot] Sieve scripts not run

Hi Matt, I try on my setup the patch you made last month and the /home/vpopmail/etc/open-smtp leaves empty. If I go back with the vpopmail mode, it is working. I don't understand what's happened really.

[Dovecot] Logging a special message into Dovecot source code
by Meisam Navaki 06 Jul '11

06 Jul '11

Hi, I wanna modify Dovecot source code.For that,I need to know how can we log a special message into Dovecot source code? I tried to write a function to write a message in a file and added it to Dovecot source code,but it didn't work. I'm wondering if we can use Dovecote logging functions,but I don't know what are those functions and how can we use them. Thanks in advance. -- *Regards Meisam Navaki Arefi, * *System Programmer, * ** *Bayan Co. * * *

[Dovecot] Public Mailbox & ACLs
by Tom Clark 06 Jul '11

06 Jul '11

Hi, I'm having a problem I can't get my head around. I'm trying to setup a public mailbox that is hidden from all users unless granted access through an ACL. My folder structure is (migrated from a Courier IMAP/Qmail server): /var/spool/maildir - main public folder (contains a few .qmail files to redirect mail to the correct subfolder) /var/spool/maildir/Support - support public folder (a public folder rather than a maildir) /var/spool/maildir/Support/.SubFolder1 - support sub folder 1 (a maildir) /var/spool/maildir/Support/.SubFolder2 - support sub folder 2 (another maildir) /var/spool/maildir/System /var/spool/maildir/System/.SubFolder1 /var/spool/maildir/System/.SubFolder2 I couldn't get the namespace working correctly to just have 1 folder called "Shared" (you just got an empty folder when trying to subscribe). I ended up making 2 namespaces below: namespace { type = public separator = . prefix = Shared.Support. location = maildir:/var/spool/maildir/Support:INDEX=~/Maildir/Support subscriptions = no } namespace { type = public separator = . prefix = Shared.System. location = maildir:/var/spool/maildir/System:INDEX=~/Maildir/System subscriptions = no } This allowed me to get the result I was looking for. Using an ACL I get a Shared->Support/System->Subfolders view. However the problem is when a user is not in the ACL they can still see the Shared->Support/System folders (just none of the subfolders) and obviously can't subscribe. Could someone let me know what I am doing wrong and if there is a better way of doing this? Many thanks, Tom

[Dovecot] Problems with acl and shared namespace
by Udo Lembke 06 Jul '11

06 Jul '11

Hi, i'm a dovecot-newbie and also new at this mailinglist. I'm try to configure an mailserver with dovecot2, postfix and postfixadmin. At this time i struggle with acl and shared namespace. My goal is, that every user get an archive-area on an separate storage without quota (quota isn't running yet). With: namespace { type = private separator = / prefix = "archiv/%u/" location = maildir:/var/data/archiv/%d/%n:INDEX=/var/data/indexes/archiv/%u:LAYOUT=fs inbox = no subscriptions = yes list = yes } I see the folder, but i can't subscribe them (with thunderbird, or roundcube). With roundcube i can add a new folder below - so i use the trick autocreate5 = archiv/%u/archiv autosubscribe5 = archiv/%u/archiv This is as workaround ok - or is this a "must be"?. But the user should also be able to share parts of the archiv-mailbox with other users (partly on different domains). If i change the type of namespace to shared, i can't access the archiv-folder. The logfile shows problems with the acl (but also with private namespace): Jun 30 11:15:11 imap(test(a)example.com): Debug: Namespace : type=shared, prefix=archiv/test(a)example.com/, sep=/, inbox=no, hidden=no, list=yes, subscriptions=yes location=maildir:/var/data/archiv/example.com/test:INDEX=/var/data/indexes/… Jun 30 11:15:11 imap(test(a)example.com): Debug: fs: root=/var/data/archiv/example.com/test, index=/var/data/indexes/archiv/test(a)example.com, control=, inbox= Jun 30 11:15:11 imap(test(a)example.com): Debug: acl: initializing backend with data: vfile Jun 30 11:15:11 imap(test(a)example.com): Debug: acl: acl username = test(a)example.com Jun 30 11:15:11 imap(test(a)example.com): Debug: acl: owner = 0 Jun 30 11:15:11 imap(test(a)example.com): Debug: acl vfile: Global ACL directory: (none) Jun 30 11:15:11 imap(test(a)example.com): Debug: Namespace : Using permissions from /var/data/mail/example.com/test: mode=0700 gid=-1 Jun 30 11:15:11 imap(test(a)example.com): Debug: acl vfile: file /var/data/archiv/example.com/test/dovecot-acl not found Jun 30 11:15:11 imap(test(a)example.com): Debug: autocreate: Failed to create mailbox archiv: Permission denied Jun 30 11:15:11 imap(test(a)example.com): Debug: Namespace archiv/test(a)example.com/: Using permissions from /var/data/archiv/example.com/test: mode=0700 gid=-1 Jun 30 11:15:11 imap(test(a)example.com): Debug: acl vfile: file /var/data/mail/example.com/test/dovecot-acl not found I'm wondering about "...dovecot-acl not found" because dovecot create an file "dovecot-acl-list" : # ls -l /var/data/archiv/example.com/test/ drwx------ 5 dovecot dovecot 4096 30.
