[Dovecot] Inherited ACLs for mailboxes created by not-owner
by Michael Stilkerich 12 Feb '12

12 Feb '12

Hi, I have shared one of my mailboxes to another user providing him full rights to that mailbox. $ doveadm acl get -u user1 doc ID Global Rights user=user2 admin create delete expunge insert lookup post read write write-deleted write-seen When that user creates a new mailbox within the shared mailbox, the mailbox is successfully created but with an empty ACL. $ doveadm acl get -u user1 doc/hallo ID Global Rights According to the wiki, it should inherit the ACL from its parent, i.e. have full permissions for user2. Dovecot logs the following errors when I access the parent folder the first time after the other user created the child mailbox: dovecot: imap(user1): Error: Mailbox doc/hallo: Corrupted index, uidvalidity=0 dovecot: imap(user1): Error: Recent flags state corrupted for mailbox INBOX dovecot: imap(user1): Error: /home/dovecot/user1/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent dovecot: imap(user1): Error: Recent flags state corrupted for mailbox Sent dovecot: imap(user1): Error: /home/dovecot/user1/mailboxes/Sent/dbox-Mails/dovecot.index reset, view is now inconsistent dovecot: imap(user1): Error: /home/dovecot/user1/mailboxes/INBOX/dbox-Mails/dovecot.index reset, view is now inconsistent This is on dovecot 2.1rc5. -Michael

[Dovecot] Some Dovecot LDA version sends MDN rather than DSN for overquota.
by Mark Sapiro 12 Feb '12

12 Feb '12

It appears that there is some version of the Dovecot LDA that is sending an RFC 3798 MDN rather than an RFC 3464 DSN to report non-delivery to a user who is over quota. See <https://bugs.launchpad.net/mailman/+bug/693134> for a discussion of this and <https://bugs.launchpad.net/mailman/+bug/693134/+attachment/1773018/+files/A…> for the actual MDN message. The issue is that apparently a user was over quota and Dovecot returned an MDN with a disposition of deleted. This is intended to mean the the mail was delivered to the user but the user deleted it without reading it. If the message was actually not delivered, this should be reported to the MTA so it can return an appropriate SMTP status, or the LDA should send an RFC 3464 DSN with an action of failed. Note that I do not actually use the Dovecot LDA nor do I have any access to the system where the notice in the bug report was received, so I may have incomplete information and this may not be relevant to current versions of Dovecot, but I think it is wrong for Dovecot to report over quota non-delivery via an MDN. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

[Dovecot] Passdb disconnected unexpectedly when trying to do Director with LMTP
by Mark Zealey 12 Feb '12

12 Feb '12

Hi there, I'm running Dovecot 2.0.16 just set up the director with cut&paste from the wiki. It's working & running fine for pop/imap connections (as verified by doveadm director status user), however when I specify 'RCPT TO' for a (tcp) lmtp connection straight away I get: 451 4.3.0 <xxx(a)yyy.com> Temporary user lookup failure and in the logs: 2012-02-11T14:22:54+00:00 xxx dovecot: lmtp(27997): Error: passdb lookup(xxx(a)yyy.com): Disconnected unexpectedly I'm sure this is an obvious issue for someone who's come across it before. The /var/run/dovecot/director-userdb socket is on the system; exactly the same permissions as the standard auth-userdb Here are the relevant bits of my config (I'm setting lmtp to listen on a different port than normal). Backend password database is mysql if that makes any difference. lmtp_proxy = yes service lmtp { inet_listener lmtp_test { port = 2450 } } protocol lmtp { auth_socket_path = director-userdb } Thanks, Mark

[Dovecot] Lost in configuration
by forumer＠smartmobili.com 12 Feb '12

12 Feb '12

Hi, I am trying to configure dovecot/postfix with virtual users and sasl auth but there are so many tutorials with mistakes and subtle differences that at the end I am lost. So I am running Ubuntu server 11.04 (natty) and when I installed my server I had followed the following guide http://workaround.org/ispmail/etch Then I have migrated to dovecot 2.1 and now I am trying to allow authenticated user to use my smtp server because for the moment I get : Relay access denied Here is my configuration (first is file hierarchy followed by file contents) and I would like to know what I need to do to allow authenticated user send email. In this tutorial http://library.linode.com/email/postfix/dovecot-mysql-ubuntu-10.04-lucid#sp… it seems I have to add some configuration lines inside /etc/pam.d/smtp and add database configuration inside /etc/postfix/sasl/smtpd.conf. But what I find weird is the fact I have to configure some sql queries from smtpd.conf while normally dovecot has already all the information to do this kind of query. So before to keep on modifying my config I would like to be sure I am following the right way.

[Dovecot] Quota Calculation seems to be wrong when using dsync
by Thomas Leuxner 12 Feb '12

12 Feb '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Recently I encountered odd quota increases when using 'dsync' with the latest and greatest: 2.0.8 (89936539e3b8). Say you got something in place like this: plugin { quota = dict:user::file:%h/mdbox/dovecot-quota quota_rule = *:storage=1GB quota_rule2 = Trash:storage=+10%% } Kick off a manual backup: $ dsync -u user(a)domain.tld backup mdbox:/<path to backup>/mdbox This results in doubling the quota for the backed up user. It doesn't seem to matter whether 'mirror' or 'backup' mode is used, both increase the "source" quota. Doesn't sound right to me. You can only get to the "real" usage by running a recalc manually: $ doveadm quota recalc -u user(a)domain.tld Anyone else seen this? Regards Thomas P.S.

[Dovecot] Migration to mdbox from Maildir, missing folders!
by Giles Coochey 12 Feb '12

12 Feb '12

So I went and migrated a mailbox from mdbox from maildir format. All seemed ok, but I've found that I now have some missing folders. The mailbox in maildir format had some folders which contained an '&' sign, these appear to have been omitted... What can be done? (I have a backup of the maildir box). Note though that mdbox is now a live mailbox and has sent and received mails since the migration... -- Message sent via my webmail account.

[Dovecot] folder hierarchies with migration from cyrus to dovecot2
by Wolfgang Rosenauer 12 Feb '12

12 Feb '12

Hi, I finally migrated my IMAP server from cyrus to dovecot2. I have been using cyrus since many years and have not much experience with dovecot yet though. I've converted my imap server using cyrus2dovecot (several times until I thought it was correct) but there is one thing left which confuses me and I'm not sure what I can or need to do to change it. With Cyrus I used unixhierarchysep: yes and subfolders within Cyrus are always below INBOX. I'm used to that in my IMAP clients and wanted to preserve it with Dovecot. So during migration I finally made sure to create the subfolder again below INBOX wich looks fine in Thunderbird for example. But my mobile devices (Android based with K9) were displaying the folders with Cyrus just with their name w/o the INBOX prefix. (Mobile clients are bad in displaying folder hierarchies so it was convenient to have them looking like they were in parallel to the Inbox.) Now I get the folders displayed as INBOX.whatever and my Android mail clients fail to map them to the special (and localized) folders like Trash. While that seems consistent to my current hierarchy it's not what I wanted. So basically my two questions are: - Can I configure Dovecot in a way that it looks like Cyrus? Having subfolders below Inbox but let clients like those on Android display them besides Inbox? - If that's not possible, can I move the subfolders up one level so they are next to the Inbox? How would I do that? Sorry for the beginner questions. I played around with Dovecot before but using it in production environment disclosed some fine differences. Thanks, Wolfgang
