Help on dict with QUOTA / perms
by Jorge Bastos 08 Nov '14

08 Nov '14

I'm setting up quota for my users, my users have a UID starting on >5000 and GID = 5000, and when I query the quota, for example in IMAP, I get: Nov 8 14:13:28 fastmail dovecot: imap-login: Login: user=<a(a)a.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=18660, secured, session=<uByciFkH2gB/AAAB> Nov 8 14:13:37 fastmail dovecot: imap(a(a)a.com): Error: net_connect_unix(/var/run/dovecot/dict) failed: Permission denied (euid=5000(<unknown>) egid=5000(<unknown>) missing +r perm: /var/run/dovecot/dict, dir owned by 0:0 mode=0755) Question is, should I have the GID on the users set to 0, or is there another way to workaround it? Thanks,

Virtual alias with dovecot
by Jorge Bastos 08 Nov '14

08 Nov '14

Hi, I've setup virtual alias/users/domains with postfix and dovecot, so far so good. In the alias table I set the information of the source and destination address, but then I try to send an email to the alias, dovecot complains about it. What am I doing wrong? Nov 7 23:04:13 fastmail dovecot: lmtp(4687): Connect from local Nov 7 23:04:13 fastmail postfix/lmtp[6556]: 1D2AC100E0A: to=<b(a)a.com>, relay=fastmail.domain.pt[private/dovecot-lmtp], delay=6.3, delays=6.2/0/0/0.06, dsn=5.1.1, status=bounced (host fastmail.domain.pt[private/dovecot-lmtp] said: 550 5.1.1 <b(a)a.com> User doesn't exist: b(a)a.com (in reply to RCPT TO command)) Nov 7 23:04:13 fastmail dovecot: lmtp(4687): Disconnect from local: Successful quit Postfix alias conf: virtual_alias_maps = mysql:/etc/postfix/mysql-virtual-alias-maps.cf cat mysql-virtual-alias-maps.cf user = posuser password = popass hosts = 127.0.0.1 dbname = postfix query = SELECT deliver_to FROM dovecot_aliases WHERE alias='%s' where the table structure is: CREATE TABLE `dovecot_aliases` ( `id` int(11) NOT NULL, `alias` varchar(255) NOT NULL, `deliver_to` varchar(255) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC; Records are, considering that the main address is a(a)a.com: Insert into dovecot_alias values (1,'b(a)a.com','a(a)a.com'); Should be postfix that should had send this to the main address right? What could be wrong? SQL Logs for this, show's that dovecot considered the alias to check if the users exists instead of the real address: 141107 23:18:12 45 Connect postfix_usr@localhost on postfix 45 Query SELECT deliver_to FROM dovecot_aliases WHERE alias='ola.pt' 46 Connect postfix_usr@localhost on postfix 46 Query SELECT 1 FROM dovecot_domains WHERE domain='ola.pt' and status='true' 141107 23:18:16 45 Query SELECT deliver_to FROM dovecot_aliases WHERE alias='a.com' 46 Query SELECT 1 FROM dovecot_domains WHERE domain='a.com' and status='true' 47 Connect postfix_usr@localhost on postfix 47 Query SELECT deliver_to FROM dovecot_aliases WHERE alias='b(a)a.com' 141107 23:18:22 45 Query SELECT deliver_to FROM dovecot_aliases WHERE alias='a.com' 46 Query SELECT 1 FROM dovecot_domains WHERE domain='a.com' and status='true' 48 Connect postfix_usr(a)192.168.69.223 on postfix 48 Query select uid,gid from dovecot_users where username='b(a)a.com' 49 Connect postfix_usr@localhost on postfix 49 Query SELECT deliver_to FROM dovecot_aliases WHERE alias='ola(a)ola.pt' 49 Query SELECT deliver_to FROM dovecot_aliases WHERE alias='@ola.pt' 45 Query SELECT deliver_to FROM dovecot_aliases WHERE alias='ola.pt' 46 Query SELECT 1 FROM dovecot_domains WHERE domain='ola.pt' and status='true' PS: offtopic, don't understand why postfix queries the sender domain in the domains table and the sender email in the alias table. Thanks in advanced, Jorge,

mail location change results in various errors
by Cliff Hayes 07 Nov '14

07 Nov '14

I have a sendmail/dovecot imap/pop3 system that has been running with the following mail_location: mail_location = mbox:/var/empty:INBOX=/var/spool/mail/%u:INDEX=/var/indexes/%u In order to reduce errors and simplify operation I removed imap and am now only responding to pop3.

Dovecot replication causing deleted emails to reappear
by Asai 06 Nov '14

06 Nov '14

Greetings, I've set up replication successfully on two Dovecot servers. I had fully synced the servers but then took one offline for 2 weeks. When I restored it, the servers synced but ended up replacing deleted emails in random people's inboxes. I'm using maildir. Does anyone have any insights as to correcting this issue? Asai -- --Asai

Dovecot-lda permission errors or maybe authentication errors?
by Robert Kryger 06 Nov '14

06 Nov '14

I am a new dovecot user who recently transitioned my old mailserver to a new CentOS/Postfix/Dovecot system. I am running a simple configuration with about a dozen system users and Maildir folders. The e-mail setup seems to be running fine when I use the default local-delivery-agent in Postfix. However, I am trying to use the dovecot-lda instead so I can take advantage of the sieve functionality. I have tried to specify the dovecot-lda in two ways. First, in the /etc/postfix/main.cf file: mailbox_command = /usr/libexec/dovecot/dovecot-lda -f "$SENDER" -a "$RECIPIENT" or alternatively, I leave the mailbox_command blank and specify the following in the .forward file of a test user: | "/usr/libexec/dovecot/dovecot-lda" Either approach gives me the same error(s). When a mail message is sent to the test user USER1, the following errors appear in the dovecot-lda error file: Nov 04 08:47:29 lda(user1): Error: chdir(/home/user1/) failed: Permission denied (euid=524(user1) egid=524(user1) stat() failed: No such file or directory, euid is not dir owner) Nov 04 08:47:29 lda(user1): Error: chdir(/home/user1) failed: Permission denied Nov 04 08:47:29 lda(user1): Error: user user1: Initialization failed: Namespace 'INBOX.': stat(/home/user1/Maildir) failed: Permission denied (euid=524(user1) egid=524(user1) stat() failed: No such file or directory, euid is not dir owner) Nov 04 08:47:29 lda(user1): Fatal: Invalid user settings. Refer to server log for more information. Nov 04 08:47:29 lda(user1): Error: chdir(/home/user1/) failed: Permission denied (euid=524(user1) egid=524(user1) stat() failed: No such file or directory, euid is not dir owner) Nov 04 08:47:29 lda(user1): Error: chdir(/home/user1) failed: Permission denied Nov 04 08:47:29 lda(user1): Error: user user1: Initialization failed: Namespace 'INBOX.': stat(/home/user1/Maildir) failed: Permission denied (euid=524(user1) egid=524(user1) stat() failed: No such file or directory, euid is not dir owner) Nov 04 08:47:29 lda(user1): Fatal: Invalid user settings. Refer to server log for more information. At first, I interpreted this to mean the file permissions were not set correctly on the home directory or the Maildir folder. However, I have opened these up to full rwx access for everyone and I still get the same errors. Alternatively, perhaps this is related somehow to the dovecot-lda authentication process via the password or user databases, but I can't make any sense of the documentation. Can anyone suggest what might be wrong or how to better diagnose? For reference, I am running dovecot version 2.0.9. The dovecot-lda process also outputs the following messages (not errors) when a test message is sent to the USER1 account: Nov 04 08:47:29 lda: Debug: Loading modules from directory: /usr/lib64/dovecot Nov 04 08:47:29 lda: Debug: Module loaded: /usr/lib64/dovecot/lib90_sieve_plugin.so Nov 04 08:47:29 lda(user1): Debug: Effective uid=524, gid=524, home=/home/user1 Nov 04 08:47:29 lda(user1): Debug: Namespace : type=private, prefix=INBOX., sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/Maildir Nov 04 08:47:29 lda(user1): Debug: maildir++: root=/home/user1/Maildir, index=, control=, inbox=/home/user1/Maildir Nov 04 08:47:29 lda: Debug: Loading modules from directory: /usr/lib64/dovecot Nov 04 08:47:29 lda: Debug: Module loaded: /usr/lib64/dovecot/lib90_sieve_plugin.so Nov 04 08:47:29 lda(user1): Debug: Effective uid=524, gid=524, home=/home/user1 Nov 04 08:47:29 lda(user1): Debug: Namespace : type=private, prefix=INBOX., sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/Maildir Nov 04 08:47:29 lda(user1): Debug: maildir++: root=/home/user1/Maildir, index=, control=, inbox=/home/user1/Maildir The output of dovecot -n is: # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.29.2.el6.x86_64 x86_64 CentOS release 6.5 (Final) auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login disable_plaintext_auth = no login_trusted_networks = 71.xx.xx.xx 71.xx.xx.xy 71.xx.xx.xz 71.xx.xx.yx mail_debug = yes mail_location = maildir:~/Maildir managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date mbox_write_locks = fcntl namespace { inbox = yes location = prefix = INBOX. separator = . } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_global_dir = home/sieve sieve_max_script_size = 1M } protocols = imap lmtp sieve service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } protocol lda { info_log_path = /var/log/dovecot-lda.log log_path = /var/log/dovecot-lda-errors.log mail_plugins = sieve postmaster_address = postmaster(a)xxxxxxx.com }

Even better it would be to have a recipe for a custom SELinux policy to not be mislead switching off SELinux at all. Such a custom policy is necessary when storing mail in the user's homedir because files created there get a wrong SELinux context for that usecase by default. An general overview about this topic can be found on http://wiki.centos.org/HowTos/SELinux Kind regards Alexander

Can I take mail from Maildir mailbox and deliver it as new?
by James Pryor 06 Nov '14

06 Nov '14

Hello list, I have a need for someone to point me in the right direction. Our old email system (system A) had an account that acted as a mailing list accumulator/archiver. This account was a member of every list and mail would be sent to it's address. The strange part is that email was not delivered to system A because there was a . (dot) forward alias to another machine (system B) that runs sendmail. System B's sendmail then slurped up the incoming mail and processed it in some fashion which I do not care about. On our new mail server (system C (OS is RHEL6.5, dovecot-2.0.9-7.el6_5.1.x86_64, postfix-2.6.6-6.el6_5.x86_64)), I performed a bulk Linux account and mailbox migration from system A to system C using postfix/dovecot/imapsync. But I forgot to put the alias in place on system C to send all incoming that special account's mail on system B. So mail started to get delivered to local user ar_list on system C. So now I have a Maildir format mailbox on system C that has mail in it and I want to be able to manipulate and/or re-send those emails as new mail to system B. Once it is received by sendmail on system B, then I don't care about it any more. Is there a way to take mail sitting on disk in a mailbox and deliver it as if it was new mail to some other machine? Thanks, James -bash-4.1$ ls -l total 566 drwx------ 2 ar_list users 2048 Aug 7 21:29 cur -rw------- 1 ar_list users 12556 Oct 8 17:09 dovecot.index -rw------- 1 ar_list users 378880 Oct 9 14:41 dovecot.index.cache -rw------- 1 ar_list users 2580 Oct 9 14:41 dovecot.index.log -rw------- 1 ar_list users 65549 Oct 9 14:41 dovecot-uidlist -rw------- 1 ar_list users 8 Aug 7 19:38 dovecot-uidvalidity -r--r--r-- 1 ar_list users 0 Aug 7 19:38 dovecot-uidvalidity.53e40ddc drwx------ 2 ar_list users 100352 Oct 9 14:41 new drwx------ 2 ar_list users 2048 Oct 9 14:41 tmp -bash-4.1$ ls new/ | wc -l 1020 -bash-4.1$ ls cur | wc -l 25

Alexander, You are absolutely right - I apologize for my confusion regarding SElinux. In fact, when I turn off SElinux in /etc/selinux/config (setting SELINUX=disabled, instead of =enforcing) then dovecot-lda starts working. Thanks for the advice - I have been fighting with this for several weeks without making headway! Robert

gssapi considered as PLAIN?
by Harry Schmalzbauer 05 Nov '14

05 Nov '14

Hello, as soon as I set "disable_plaintext_auth = yes", AUTH=GSSAPI vanishes from capabilities. ([CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=GSSAPI AUTH=PLAIN AUTH=LOGIN] vs [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS LOGINDISABLED]) Why? I'm wondering especially because at http://wiki2.dovecot.org/Authentication/Mechanisms, GSSAPI is correctly listed under “Non-plaintext authentication“. Thanks, -Harry

ntlm_auth seems ok, initial auth failure with dovecot2 (and winbind 4.1.13)
by Harry Schmalzbauer 05 Nov '14

05 Nov '14

Hello, I've read quite often that there are problems with ntlm_auth helper (last one here http://www.dovecot.org/list/dovecot/2014-June/096561.html) But haven't found any confirmation, neither it's working for anybody else nor that it's known taht this issue needs debuging. Like for ohers, my authentication tests from the commandline with ntlm_auth exactly give expected results. But initial authentication (with Outlook) fail at first, but after entering the user's password, nevertheless succeeds with mech=NTLM. See the attached ntlm-log.txt Can't exactly tell when this regression occured, one year ago nobody had to enter his password, it worked like intended with Outlook (which still is version 2010). Any idea how to debug? It could be also a regression in samba, both highly appreciated applications were upgraded at the same time… Thanks, -Harry

calling post-login script with doveadm
by Héctor Moreno Blanco 05 Nov '14

05 Nov '14

Hello everyone, I'm trying to execute some commands with doveadm but I need some information loaded in a post-login script before running these commands. Is possible to run the post-login script while executing doveadm? I've found how to do something similar with -o key=value to override settings, but I want to change a namespace location, as done in the post-login script: ... export USERDB_KEYS="$USERDB_KEYS namespace/archivo/location" exec env "NAMESPACE/ARCHIVO/LOCATION=$location" "$@" ... Thank you very much in advanced. Kind regards.

Public mailbox confusion
by Stefan G. Weichinger 05 Nov '14

05 Nov '14

greets, I am quite sure I ask some faq here ... sorry, but I am confused by the many options and choices here. What I want to do is: I migrate lots of public folders from a MS Exchange Server ... The customer wants that there is a "Public" folder containing all these hundreds of folders, the public folder should be visible for all the dovecot-users and all the subfolders should be automatically subscribed as soon a new user logs in. What I have now: namespace { type = private separator = / prefix = inbox = yes } namespace { type = public separator = / prefix = Public/ location = maildir:/home/vmail/public:INDEXPVT=/home/vmail/public/index/%d/%u/index subscriptions = yes } As far as I see from testing this doesn't yet work that way. When I open the mailbox with eg. roundcube I see "Public" but nothing below it ... Could someone please give me a good pointer here? Thanks! Stefan

sieve replication and .dovecot.lda-dupes
by Jan Behrend 05 Nov '14

05 Nov '14

Hello list, I have a replicated dovecot with two servers. People seem to get vacation responses more often then it is specified in "days: XX", depending on which dovecot instance they receive the incoming mail. Is ".dovecot.lda-dupes" replicated? The other problem is that the vacation response is coming from the wrong address depending on which field the recipient was listed: "to:" or "cc:" Here is my test example: g9-rz has the vacation rule set up: date | mail -s test -r jbehrend(a)mpifr-bonn.mpg.de -c g9-rz(a)mpifr-bonn.mpg.de jan(a)flatpick.de and this returns this vacation response: ### snip ### Return-Path: <> Delivered-To: <jbehrend(a)mpifr-bonn.mpg.de> Received: from mail2.mpifr-bonn.mpg.de ([134.104.18.60]) by mailbox2.mpifr-bonn.mpg.de (Dovecot) with LMTP id +pgPDzm1WFSn9wAAvl5QjA for <jbehrend(a)mpifr-bonn.mpg.de>; Tue, 04 Nov 2014 12:16:13 +0100 X-Sieve: Pigeonhole Sieve 0.4.2 Message-ID: <dovecot-sieve-1415099773-541512-0(a)mailbox1.mpifr-bonn.mpg.de> Date: Tue, 04 Nov 2014 12:16:13 +0100 From: jan(a)flatpick.de To: <jbehrend(a)mpifr-bonn.mpg.de> Subject: Vacation In-Reply-To: <E1Xlc5t-0001LT-Bu(a)jb1.mpifr-bonn.mpg.de> References: <E1Xlc5t-0001LT-Bu(a)jb1.mpifr-bonn.mpg.de> Auto-Submitted: auto-replied (vacation) Precedence: bulk MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 8bit X-Evolution-Source: 1385020682.6450.3@jb1 Ain't here!

With as much information as you already have in your database schema you may want to look at using the Prefetch userdb. http://wiki2.dovecot.org/UserDatabase/Prefetch P.S. Apologies for the duplication. I forgot to reply to the list with my last response.

SSL Client authentication with trustcenter-certificate
by dovecot.pkoch＠dfgh.net 04 Nov '14

04 Nov '14

Dear reader, we are using dovecot 2.2.7 and like it very much. Authentication is done via a checkpassword program that does two things: 1) check wether the client has connected via SSL using a client certificate 2) check wether the client is using a one time password generator Most of our users are using certificates that we have created ourself. These certificates contain a x500uniqueidentifier. But some users are using certificates from a german trust center and these certificates do not contain a x500uniqueIdentifier nor something similar. I would like to map these certificates to user accounts and my first idea was to do so from my checkpassword programm. But how do I find out the client-certificate from within a checkpassword script. I tried to add an additional entry to auth_request_var_expand_static_tab and fill in that environment variable in auth_request_get_var_expand_table_full() (both in src/auth/auth-request.c). But where do I find the SSL-context from which I can extract the client certificate? Kind regards Peter Koch

Released Pigeonhole v0.4.6 for Dovecot v2.2.15.
by Stephan Bosch 02 Nov '14

02 Nov '14

Hello Dovecot users, Version 0.4.5 introduced one new 'feature', but it caused build problems. This release fixes that. If you've successfully installed 0.4.5, you do not need to upgrade. Changelog v0.4.6: - After make distclean, the distributed tarball would fail to recompile. This causes problems for some distribution builds. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.6.tar… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.6.tar… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

Released Pigeonhole v0.4.5 for Dovecot v2.2.15.
by Stephan Bosch 02 Nov '14

02 Nov '14

Hello Dovecot users, Unfortunately, Pigeonhole v0.4.4 had a rather big issue with error handling and the execution of the implicit keep. This problem presented itself for example when users exceeded their quota. This did not result in the proper rejection message. This is why I quickly release a new version. Changelog v0.4.5: + Added a Pigeonhole version banner to doveconf output. This way, future bug reports will also include Pigeonhole version information. - Fixed handling of implicit keep. Last version erroneously reported that implicit keep succeeded after an earlier failure, while it in fact had failed. Particularly occurred for mailbox quota errors. - Fixed segfault occurring on SunOS systems when there is no active script. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.5.tar… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.5.tar… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl
