[Dovecot] Status

So, just some quick notes: - dovecot.org server was down a couple of days again, need to find time to move it to a VM.. - my tss(a)iki.fi emails were also broken for some hours at least and it was bouncing back all mails to it during the time - I fixed some bugs reported by people, but I did it in airplane so couldn't reply back with links to the fixes in hg repo. I'll probably do that tomorrow. But you can already check if your reported bug has been fixed in http://hg.dovecot.org/dovecot-2.2 - I'm planning on going through Dovecot list's mails this week and make v2.2.11 release - although it looks like I've a flu, so lets see how far I can get.. - hopefully by the beginning of March I'll have more time again

[Dovecot] Sieve is not getting the propper RCPT from the LMTP daemon
by klondike 14 Feb '14

14 Feb '14

Hi! Since the setup I use is a bit strange let's go for it first: * The system uses postfix as MTA and dovecot as LDA after alias translation by local via LMTP * The dovecot version is 2.2.5 and the pigeonhole version is 0.4.1 * The SMTP server at gentoo.org is configured to send me a backup of my emails to klondike+gentoo (at) xiscosoft.es using sendmail * The email is received by the server and then (hopefully filtered). * The email comes with two Delivered-To: headers, the first one has the correct address, the second one has the gentoo address. The interesting part of the filter is this: if envelope :detail "to" "gentoo" { addflag "\\Seen"; fileinto "gentoo"; stop; } But this doesn't seem to work, I enable debugging with the following lines: require "vnd.dovecot.debug"; require "envelope"; require "variables"; if envelope :matches "to" "*" { debug_log "envelope to `${1}'"; } if envelope :matches "from" "*" { debug_log "envelope from `${1}'"; } The relevant lines for the test e-mail I sent are these: sieve: info: started log at Dec 24 13:37:23. main script: line 9: info: DEBUG: envelope to `klondike (at) gentoo.org'. main script: line 10: info: DEBUG: envelope from `klondike (at) gentoo.org'. info: msgid=<52B97FF7.6050109(a)gentoo.org>: stored mail into mailbox 'INBOX'. The thing is that the to envelope should be instead klondike+gentoo (at) xiscosoft.es as show by the lmtp logs: Dec 24 13:37:23 localhost dovecot: lmtp(26249): Connect from local Dec 24 13:37:23 localhost dovecot: lmtp(26249, klondike): Cd6YHwOAuVKJZgAA0J78UA: sieve: msgid=<52B97FF7.6050109(a)gentoo.org>: stored mail into mailbox 'INBOX' Dec 24 13:37:23 localhost dovecot: lmtp(26249): Disconnect from local: Successful quit Dec 24 13:37:23 localhost postfix/lmtp[26248]: 657D9101E5E: to=<klondike+gentoo (at) xiscosoft.es>, relay=xiscosoft.net[private/dovecot-lmtp], delay=0.29, delays=0.05/0.03/0.03/0.18, dsn=2.0.0, status=sent (250 2.0.0 <klondike+gentoo (at) xiscosoft.es> Cd6YHwOAuVKJZgAA0J78UA Saved) I really have no idea of why sieve is behaving like this as the evelope address is sent properly by postfix's lmtp according to the logs. Any ideas? klondike PS: please do CC me when answering this e-mail as I'm not subscribed to the list yet

[Dovecot] master user and ACL's
by Peter Mogensen 14 Feb '14

14 Feb '14

Hi, Quick question...I read in the docs that: "Master user is still subject to ACLs just like any other user, which means that by default the master user has no access to any mailboxes of the user." ... and that the standard workaround is to return master_user=%u from the userdb. But why is the master_user authn-id used in the ACLs and not the authz-id (requested-login-user) ? Isn't the whole point of SASL authz-id semantics to have authorization resolved based on the authz-id? /Peter

[Dovecot] Public folder doesn't work
by vupibi 14 Feb '14

14 Feb '14

Hey, I have some issues with dovecot, because the public folder won't show up in Mail accounts. Dovecot is installed via zentyal 3.3. I tried several settings, but I dont get it running. What I tried is adding this to my dovecot.conf file # User's private mail location mail_location = maildir:~/Maildir # When creating any namespaces, you must also have a private namespace: namespace { type = private separator = / prefix = #location defaults to mail_location. inbox = yes } namespace { type = public separator = / prefix = Public/ location = maildir:/var/vmail/public subscriptions = no } But nothing happened. I tried it with # Umask for shared folders umask = 0007 with subscriptions = yes tried creating the folder first like this touch /var/vmail/public/dovecot-shared chown -R ebox /var/vmail/public find /var/vmail/public -type d -print0 | xargs -0 chmod 2770 find /var/vmail/public -type f -print0 | xargs -0 chmod 660 But i had no success. Any Ideas how to get it running?

[Dovecot] Some LDA questions!

Hi there! I have been setuped exim and dovecot. Exim uses dovecot-lda to deliver mails to mailbox. Some configurations of exim: dovecot_virtual_delivery: driver = pipe command = /usr/libexec/dovecot/dovecot-lda -d $local_part@$domain -f $sender_address message_prefix = message_suffix = delivery_date_add envelope_to_add return_path_add log_output user = vmail group = vmail #mode = 0660 temp_errors = 64 : 69 : 70: 71 : 72 : 73 : 74 : 75 : 78 dovecot does mysql lookups of users, passwords. All works, but in headers of example message: Return-path: <"vitalyf(a)bbb.com"@host.aaa.com> Envelope-to: vitalyf(a)bbb.com Delivery-date: Tue, 11 Feb 2014 03:59:17 -0600 Received: from xxx.net ([11.22.33.44] helo=[192.168.1.77]) by host.aaa.com with esmtpsa (TLS1.0:ECDHE_RSA_AES_128_CBC_SHA1:128) (Exim 4.82) (envelope-from <"vitalyf(a)bbb.com"@host.aaa.com>) id 1WDA7Y-0007GS-VR for vitalyf(a)bbb.com; Tue, 11 Feb 2014 03:59:17 -0600 Message-ID: <52F9F468.9030001(a)bbb.com> Date: Tue, 11 Feb 2014 16:59:04 +0700 From: =?UTF-8?B?0KTQsNC00LXQtdCyINCS0LjRgtCw0LvQuNC5INCb0YzQstC+0LLQuNGH?= <vitalyf(a)bbb.com> User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:24.0) Gecko/20100101 Thunderbird/24.3.0 MIME-Version: 1.0 To: vitalyf(a)bbb.com Subject: adfasdf Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 7bit Sender: "vitalyf(a)bbb.com"@host.aaa.com Test headers host.aaa.com is a hostname that run dovecot and exim. bbb.com is a virtual domain located in mysql db.

[Dovecot] Exclude Users from replication/sync
by Daniel Stoye 14 Feb '14

14 Feb '14

Hi All, i'm searching for a way to exclude certain users from dovecots replication mechanism. I can't use the first_valid_uid setting, because the uid of my pam (ldap) users und my system users are mixed up. So, is there a way to limit my users i currently have in my userdb or somehow exclude specific uids from replication? Thanks, Daniel

[Dovecot] v2.2.12 released
by Timo Sirainen 14 Feb '14

14 Feb '14

http://dovecot.org/releases/2.2/dovecot-2.2.12.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.12.tar.gz.sig POP3 server code changes rarely, so I haven't spent time adding automated testing for it. So of course now that it changed in v2.1.11 there was a bug that caused it to crash most of the time (except for the test case I was using while developing it). This release fixes it, no other changes.

[Dovecot] Dovecot 2.2.10 crash / infinite loop bug
by Jani Hast 14 Feb '14

14 Feb '14

Hello, I though this bug should be reported, although there is workaround already made and in use. Dovecot 2.2.10 crashes into out of memory error when there is defined system users (userdb+passdb) and own virtual users (userdb+passdb). Removing either one solves the issue and Dovecot is working as it should. When memory leak (I replaced pw_init and gr_init with the version that is found from 2.1.17) is fixed from lib/ipwd.c source, the auth worker gets to infinite loop and authentication timeouts(timeout was increased, but worker does not end what ever it's doing). This far I got chance to debug this before other passdb was removed due lack of time. Here's logs, configs and backtrace: Feb 1 07:39:19 openbsd dovecot: auth-worker(30906): Fatal: pool_system_realloc(268435456): Out of memory Feb 1 07:39:19 openbsd dovecot: auth: Error: auth worker: Aborted request: Worker process died unexpectedly Feb 1 07:39:19 openbsd dovecot: auth-worker(30906): Fatal: master: service(auth-worker): child 30906 returned error 83 (Out of memory (service auth-worker { vsz_limit=256 MB }, you may need to increase it) - set CORE_OUTOFMEM=1 environment to get core dump) Feb 1 07:39:19 openbsd dovecot: auth: Error: static(email@localhost): passdb doesn't support lookups, can't verify user's existence Feb 1 07:39:19 openbsd dovecot: lda: Error: user email@localhost: Auth USER lookup failed Feb 1 07:39:19 openbsd dovecot: lda: Fatal: Internal error occurred.

[Dovecot] sqlite queries for master user
by Alan Chandler 14 Feb '14

14 Feb '14

Hi I am trying to achieve the following functionality "usera" can't login because his account is set non active. there is a deny query that checks this. a master user ("masteruser") should be able login using "usera*masteruser" syntax to this disabled account I just tried it with auth_debug set on, but the deny query is being run for usera, presumably because my master definition is passdb { driver = sql master = yes args = /etc/dovecot/sqlite-master.conf # Unless you're using PAM, you probably still want the destination user to # be looked up from passdb that it really exists. pass=yes does that. pass = yes } with pass=yes, and that causes usera to be validated through both the deny and accept phase of authorisation. In the password_query defined in sqlite-master.conf I user '%u' to locate my master user. Is there any variable I could use to (in that query) to also check that "usera" exists? I could then remove the pass = yes, both to avoid two more queries and to avoid the trap that this account is locked out. Alternatively some other parameter in the passdb segment above to tell the other login to miss the deny stage.
