[Dovecot] Importing emails from PST Archives
by Andre Rodier 27 Mar '13

27 Mar '13

Hello everyone, I am currently migrating a small company from exchange 2003 to Dovecot. So far, the most painful process has been the PST archives. (Except the inconditionals of Outlook) I have been able to create the directory structure using the last version of readpst, with the -r flag. But once this done, I have not been able to find one tool that worked correctly. Maybe the configuration I have is complex. The perl script to transform mbox files into maildirs in the dovecot distribution is old, and crashed many times in the middle of the process. I had a look to the script, and gave up trying to fix it. I found a python script that was supposed to crawl this folder structure, and to replicate it using IMAP commands, but it crashed as well, and restarting the process would import twice the same messages. The script is here: http://costela.net/2011/06/importing-an-outlook-pst-into-imap/ I found another python script that was working better, and seemed to be well written, but with one mbox to one IMAP folder only. It can be found here: http://imap-upload.svn.sourceforge.net/viewvc/imap-upload/trunk/ I have modified, and I have added some minor fixes: - Recursively traverse a folder structure, and replicate it using IMAP commands on the server. - Properly manage folder names with special characters. (dovecot can manage these characters using the listescape plugin). - Avoid taking all the resources of the server (A quirty hack that can change). I am not an expert in Python, and the script has been quickly writter to fit my needs. However I think it can be modified easily to any configuration. In the future, maybe this script can use the libpst python bindings to import the emails directly. The last version of the script, modified is here: https://github.com/arodier/EmailTools/tree/master/Migration. Do not hesitate to help me, to make the script as generic as possible, particularly if you are a python expert. I post this on this list, because I think you maybe interested if you are in the same case as me. The license is not specified, but I will probably use GPLv3. Regards, André

[Dovecot] Released Pigeonhole v0.2.4 for Dovecot v2.0.14
by Stephan Bosch 26 Mar '13

26 Mar '13

Hello Dovecot users, I release a new version of Pigeonhole tonight. This release extends the configuration capabilities of the include and vacation extensions, adds the ihave extension (RFC 5463), and fixes a few small other things. Judging by Timo's plans, this will be one of the last feature releases for Dovecot v2.0, since I'll be switching active development to Dovecot v2.1 once that matures a little more. Changelog v0.2.4: + Vacation extension: finally added support for using the original recipient in vacation address check. It is also possible to disable the recipient address check entirely. Check doc/vacation.txt for configuration information. + Include extension: made limits on the include depth and the total number of included scripts configurable. Check doc/include.txt for configuration information. + Implemented ihave extension. This allows checking for the availability of Sieve language extensions at 'runtime'. Actually, this is checked at compile time. At runtime the interpreter checks whether extensions that were not previously available are still unavailable. If the situation changed, the script is re-compiled and the ihave tests are evaluated again. + Sieve: optimized compilation of tests that yield constant results (i.e. known at compile tme), such as 'true' and 'false'. No code is produced anymore for script sections that are never executed. Also, semantics are not verified anymore in uncompiled script sections. + Made vnd.dovecot.debug extension available to the LDA plugin instead of only the command line tools. + Sieve: redirect action now adds X-Sieve-Redirected-From header (mainly for people using SPF/SRS). - Sieve: fixed bug in handling flags and keywords; in case of error an assertion was triggered. - Script storage: improved handling of unconfigured user home directory. Originally this would produce an unhelpful error message. - Imap4flags extension: prevent forcibly enabling imap4flags when imapflags is enabled. - Fixed various -Wunused-but-set-variable compiler warnings. - Include extension: forgot to check variable identifier syntax for 'global' command. - Sieve: fixed debug mode; no messages were logged in some situations. - sievec tool: forgot to enable -D (debug) parameter. The release is available as follows: http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.4.tar.gz http://www.rename-it.nl/dovecot/2.0/dovecot-2.0-pigeonhole-0.2.4.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.0 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

[Dovecot] Per-user seen flags for public read-only mailboxes
by Guido Berhoerster 26 Mar '13

26 Mar '13

Hi, I have some trouble getting per-user SEEN-flags to work with read-only mailboxes in a public namespace. Basically, I'm following the wiki at http://wiki2.dovecot.org/SharedMailboxes/Public#Maildir:_Per-user_.2BAFw-Se… and the relevant configuration is as follows: namespace { inbox = yes location = prefix = separator = / type = private } namespace { location = maildir:/srv/mail/public:LAYOUT=fs:INDEX=~/public prefix = Public/ separator = / subscriptions = no type = public } plugin { acl = vfile ... } protocol imap { mail_plugins = " acl quota trash zlib autocreate imap_acl imap_quota imap_zlib" } I have a virtual-user setup with static userdb and there is no permissions problem since everything is created through dovecot: mail_gid = vmail mail_location = mdbox:~/mdbox mail_uid = vmail [...] userdb { args = uid=vmail gid=vmail home=/srv/mail/virtual/%n driver = static } The content of /srv/mail/public/dovecot-acl (and the one of all mailboxes below it) is: owner lrwstipekxa authenticated lr Users can access all mailboxes in the Public/ namespace and read the messages and I can see that dovecot.index.cache and dovecot.index.log are created under ~/public, however setting the SEEN flag for a message is ignored since the mailbox is read-only. Changing the ACL from authenticated lr to authenticated lrs allows user to set the SEEN flag, but globally on the actual mailbox. How can I get per-user SEEN flags to work? The Dovecot version is 2.0.9. Thanks, -- Guido Berhoerster

[Dovecot] Dovecot 2.1.15 on CentOS 6.4 with metadata-plugin
by Bruce Marriner 25 Mar '13

25 Mar '13

Hello, I hope somebody can help me with this :) I am trying to get Dovecot 2.1 working with Kolab 3.0 and to start that processes I need? to compile the Dovecot metadata plugin with Dovecot. For the plugin to compile correctly against the Dovecot source code Dovecot must first be patched with a patch from the plugin author (Dennis Schridde) that is currently not part of the Dovecot code (Timo, could this be added to Dovecot?) I am documenting this entire process and once it's finished it may also be helpful to the Dovecot community. You can see some of my progress, or lack of, and errors here : http://bmts.us/wiki/doku.php?id=article:kolab:dovecot In order to compile the plugin I have removed CentOS yum packages for autoconf, automake, and libtool and downloaded, compiled, and installed versions autoconf 2.69, automake 1.12.6, and libtool 2.4.2. If I download Dovecot (not from hg) I can run ./configure and make without any problems. But, to add the patch to Dovecot I need to run the autoreconf command and this is where I have trouble. [root@kolab dovecot-2.1.15]# autoreconf aclocal: warning: autoconf input should be named 'configure.ac', not 'configure.in' configure.in:284: warning: macro 'AM_ICONV' not found in library configure.in:284: error: possibly undefined macro: AM_ICONV If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. autoreconf: /usr/local/bin/autoconf failed with exit status: 1 I read this is related to gettext, so I installed gettext 0.18.2 from source and now I get the following errors : [root@kolab dovecot-2.1.15]# autoreconf aclocal: warning: autoconf input should be named 'configure.ac', not 'configure.in' automake: warning: autoconf input should be named 'configure.ac', not 'configure.in' automake: warning: autoconf input should be named 'configure.ac', not 'configure.in' src/plugins/acl/Makefile.am:16: error: 'module_LTLIBRARIES' is used but 'moduledir' is undefined src/plugins/acl/Makefile.am:19: warning: variable 'lib01_acl_plugin_la_SOURCES' is defined but no program or src/plugins/acl/Makefile.am:19: library has 'lib01_acl_plugin_la' as canonical name (possible typo) src/plugins/acl/Makefile.am:14: warning: variable 'lib01_acl_plugin_la_LDFLAGS' is defined but no program or src/plugins/acl/Makefile.am:14: library has 'lib01_acl_plugin_la' as canonical name (possible typo) src/plugins/autocreate/Makefile.am:11: error: 'module_LTLIBRARIES' is used but 'moduledir' is undefined src/plugins/autocreate/Makefile.am:14: warning: variable 'lib20_autocreate_plugin_la_SOURCES' is defined but no program or src/plugins/autocreate/Makefile.am:14: library has 'lib20_autocreate_plugin_la' as canonical name (possible typo) src/plugins/autocreate/Makefile.am:9: warning: variable 'lib20_autocreate_plugin_la_LDFLAGS' is defined but no program or src/plugins/autocreate/Makefile.am:9: library has 'lib20_autocreate_plugin_la' as canonical name (possible typo) ... ... ... ... autoreconf: automake failed with exit status: 1

[Dovecot] doveadm with multiple commands
by Timo Sirainen 25 Mar '13

25 Mar '13

This has been in my TODO for a while and today I implemented it (but didn't dare to test it yet :) So the problem has been that you want to run for example: doveadm expunge -A mailbox Trash savedbefore 7d doveadm purge -A This is annoying because it scans through the users' mailboxes twice, wasting disk IO and CPU. So how to make it do the scan only once? The syntax I thought of today would be: doveadm multi [-A | -u wildcards] <separator string> <comand 1> [<separator string> <command 2> [...]] So the first two commands could be for example: doveadm multi -A : expunge mailbox Trash savedbefore 7d : purge The ':' character is the separator. Any other string could be used as well, for example "?SEP?" or whatever. Thoughts? Any better name for the command than "multi"?

[Dovecot] Dovecot v2 multiple domains
by Pavel Dimow 25 Mar '13

25 Mar '13

Hello, I would like to have multiple domains on same server (with different ip's) and I want that user logs with username with domain part for every domain, but I can't find any documentation on this. To be more precise I found a post regarding dovecot v1 that suggest making separate init scripts for every domain but it also suggest that dovecot v2 will support this in code. This is the post http://dovecot.org/pipermail/dovecot/2006-April/012455.html Am I missing something or this is not still possible?

[Dovecot] Dovecot DNS queries its own host many times a second
by Dominic Malolepszy 25 Mar '13

25 Mar '13

Hi, We have observed that Dovecot appears to make a DNS lookup of its own hostname many times a second. Each Dovecot server in our cluster appears to be doing around 50 queries per second to find out its own hostname. Rsyslog was the first thing we assumed was the cause, however stopping it did not help. Also the fact that at the time Dovecot was doing around 50 logins a second, seemed to correlate with it making these queries. Is there any reason why Dovecot would need to do a lookup of its own hosts IP address every time? Seems like a strange thing to do and not cache its own hostname. Dominic

[Dovecot] Confirmation Please - Dovecot for Email Delivery
by craig.dovecot＠noboost.org 25 Mar '13

25 Mar '13

Hi All, Spec: Centos 6.3x64 Dovecot-2.0.9-5.el6.x86_64 Goal: 1) Inbound emails are delivered by Dovecot and the UID/GID is determined by a local /etc/dovecot/users file. 2) I'd like to have IMAPS clients authenticate with Dovecot via LDAP. Questions: 1) I've attempted to ensure that Dovecot will always use the local password file for mail delivery as no actual password is needed. Then the LDAP server for when the IMAPS email client connects. This appears to be working as I expect, can anyone confirm/deny the below settings are correct? 2) Is there a Dovecot architecture diagram/documentation anywhere? Settings: ------------------------------------------------------------------------- File: dovecot.conf protocols = imap lmtp listen = * File: 10-auth.conf disable_plaintext_auth = yes auth_username_format = %Ln auth_mechanisms = plain !include auth-passwdfile.conf.ext !include auth-ldap.conf.ext File: auth-passwdfile.conf.ext mail_location = maildir:/home/%n/Maildir #passdb { # driver = passwd-file # args = username_format=%n /etc/dovecot/users #} userdb { driver = passwd-file args = username_format=%n /etc/dovecot/users } File: dovecot-ldap.conf.ext hosts = sysvm-ipa.noboost.org tls = yes tls_ca_cert_dir = /etc/openldap/certs auth_bind = yes auth_bind_userdn = uid=%u,cn=users,cn=accounts,dc=noboost,dc=org base = cn=users,cn=accounts,dc=noboost,dc=org pass_attrs = uid=user pass_filter = (&(objectClass=posixAccount)(uid=%u)) File: /etc/dovecot/users craig:x:890:432:Craig:/home/craig:/bin/bash ------------------------------------------------------------------------- cya Craig

[Dovecot] Reduce logging auth-worker
by Nick Edwards 25 Mar '13

25 Mar '13

Hello Timo We would like to reduce the logging by increasing severity, we don't use syslog since we use log_path = /var/log/dovecot/pop3.log Is there a way auth-worker can be made to log warn|error instead of info? Constantly 1/5th of the log file is filled with auth-work info connecting to mysql socket, which we do not need to see unless, well, we need to see it either via debug, or if there is a problem, I know this can be done from syslog, but we prefer not to use syslog, and the wiki does not indicate it can be done?

[Dovecot] SiS attachment file larger than expected
by Erik Persson 25 Mar '13

25 Mar '13

Hello! Name's Erik and I have been using Dovecot for a few months and I so far quite happy with the software. To this list I am quite new though. After a testing period I have now been running a ~300 user system running CentOS 6 and Dovecot 2.1.14 with Postfix and SiS enabled. For the large part the system is running flawlessly but I have caught a few error messages: imap(censored(a)censored.domain): Error: Attachment file /mail/attachments/70/d0/70d04b12123bfb145983f5a674ee2e65029a4018aff1c6db51993b75f10bf101-117a1a3b06f54251e96200004d877aa0 larger than expected (370113) The total number of files that I have found complaints about in the log are less than 10 accessed by 3 users in a attachment file system that by now is housing 100k + files. The only common denominator I have found so far is that all the attachments are PDF files. Most if not all of the logged files are the only referenced link of the corresponding hash. Any idea what might be causing this and how it can be prevented? I do like to be a bit paranoid when it comes to data integrity. As I am not completely familiar with the dovecot tools I also wonder if there is a way to find the offending message in the mailbox other than trying to access it via a mail client? Best regards and keep up the good work! /Erik

[Dovecot] Reporting on user info
by Alex 24 Mar '13

24 Mar '13

Hi all, I've just installed fc18 with dovecot-2.1.15 and have all the usual services set up and running properly. Of course now management is interested in who is using what service, for how long. Are there any existing reporting features available from within dovecot to provide stats on mail usage over time? Ideally, I'd like to provide a log file and find out who used each service, how long they were logged in, and from where they logged in. It would also be interesting to have a real-time view of who's connected. Does any such utility exist? Thanks, Alex

[Dovecot] Replicator updates
by Timo Sirainen 24 Mar '13

24 Mar '13

Some new features in hg: - replicator now correctly saves/restores state on exit/startup. it won't immediately start resyncing everyone now always. - if sync fails for user, retry in 5 minutes - doveadm replicator status: Give overview of replication status - doveadm replicator status <usermask>: Show users' replication status - doveadm replicator replicate [-p <priority>] <usermask>: Replicate users now. replication_full_sync_interval was also changed to 24h by default. I was thinking that with that and a nightly cronjob running "doveadm replicator replicate '*'" the full syncs could only be done during night times.

Re: [Dovecot] Migrating password scheme
by Joseph Tam 24 Mar '13

24 Mar '13

I tried the userdb prefetch / postlogin script method to do some password manipulation, but it doesn't appear to work for me. In particular, I don't think this method works with userdb { driver = passwd-file args = /path/to/passwd-file userdb_pw=%w } because it doesn't understand arbitrary var=value in the args configuration. Dvoecot seems to accept the entire string as the pathname for a password file. Is there a way to pass the plaintext password to a post-login script using passwd-file userdb? Before this, I managed password manipulation by process tracing dovecot's auth process read() syscalls and parsing out the user/password from the second buffer argument. Quite a hack but it worked.

[Dovecot] Migarting password scheme
by lst_hoe02＠kwsoft.de 24 Mar '13

24 Mar '13

Hello, by the move to Dovecot we try to alter the password encryption stored in the database from MD5 to CRYPT-SHA256 along the Guide at http://wiki2.dovecot.org/HowTo/ConvertPasswordSchemes. It's mostly working but i still have not found out how to pass the cleartext password to the re-encrypting script. According to the HowTo it should be enough to add "'%w' AS userdb_plain_pass" to the passdb query, to get a environment variable $PLAIN_PASS in the post-login script to pass along. This does not work eg. PLAIN_PASS is always empty. This is Dovecot 2.0.19 from Ubuntu 12.04 LTS. Thanks for any help Regards Andreas

[Dovecot] Disallow POP3 from deleting messages
by DormitionSkete＠hotmail.com 23 Mar '13

23 Mar '13

I'd like to use Dovecot as our IMAP server when our users are within our LAN, but I'd also like to give them the ability to access their emails via POP3 when they are outside the LAN. I know most POP3 clients will give their users the option of not deleting the messages from the server after they are downloaded, but is there any way to restrict them from being able to do so at the server level? In other words, I want to disallow the server from accepting the DELE command from POP3 clients. Is that possible? We have some accounts that multiple users need simultaneous access to. I don't want a user to decide to set up a POP3 account on his own on his iPad or something, and inadvertently blow the Inbox away for everybody else. We have a satellite connection, so our upload speeds are real slow. I think POP3 would give a lot better user experience than IMAP when they are outside the LAN. Any help or advice will be greatly appreciated. Peter, hieromonk ---- Dormition Skete Monastery Website: http://www.DormitionSkete.org Convent Website: http://www.HolyApostlesConvent.org ----

[Dovecot] Altmove doesn't working after a dsync.
by Breno Moreira 22 Mar '13

22 Mar '13

Hi guys, I'm having a problem with the altmove command after a mailbox migration using dsync. What I'm trying to do is move some users from a datacenter to another and, for that, I'm using the dsync feature. First thing I do is run the dsync mirror command, and this is working properly, but all mails are moved to the main path, ignoring the ALT statement in the mail location. So, what I tried to do was run the doveadm altmove to move the old mails to the new alternate storage, but it simply doesn't work or sometimes moves only few messages. After the user receives new messages, these new files are correctly moved. It can be problem with my search parameter in the altmove command? Or this is a normal result? Best Regards, Breno Moreira -- --------------------------------------------------------------------- Breno Moreira

[Dovecot] How do I enable dsync sieve script replication?
by Oli Schacher 22 Mar '13

22 Mar '13

Hi all, Thank you Timo for adding sieve script replication to dsync, much appreciated! Should this run out of the box with 2.2.rc3 and latest pigeonhole+patch or does this have to be enabled in the configuration somehow? I upgraded my dsync replication test setup, but it doesn't sync sieve so far, so I'm not sure if this is a config issue or if I maybe made a mistake while upgrading/patching. btw: not sure if you saw this bugreport, dsync over tcp still produces "no command given" errors randomly (http://www.dovecot.org/list/dovecot/2013-March/088751.html) Thanks Oli #dovecot -n: # 2.2.rc3: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.22.1.el6.x86_64 x86_64 CentOS release 6.3 (Final) auth_master_user_separator = * auth_mechanisms = plain login dict { acl = mysql:/etc/dovecot/dovecot-dict-shares.conf quotadict = mysql:/etc/dovecot/dovecot-dict-quota.conf } disable_plaintext_auth = no doveadm_password = <munged> listen = * login_greeting = Dovecot ready. mail_max_userip_connections = 50 mail_plugins = " quota notify replication" 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 namespace { list = children location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } namespace inbox { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Spam { auto = subscribe special_use = \Junk } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { acl = vfile:/etc/dovecot/acls acl_shared_dict = proxy::acl mail_replica = tcp:<munged>:1337 quota = dict:::proxy::quotadict quota_rule = *:storage=10M:messages=1000 quota_rule2 = Spam:ignore quota_rule3 = Trash:storage=+100M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=75%% quota-warning 75 %u sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = pop3 imap lmtp sieve service aggregator { fifo_listener replication-notify-fifo { user = fumail } unix_listener replication-notify { user = fumail } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = fumail mode = 0660 user = fumail } user = root } service dict { unix_listener dict { mode = 0600 user = fumail } } service doveadm { inet_listener { port = 1337 } } service imap { vsz_limit = 2 G } service lmtp { inet_listener lmtp { address = 127.0.0.1 port = 24 } process_min_avail = 5 unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } service managesieve { vsz_limit = 2 G } service pop3 { vsz_limit = 2 G } service quota-warning { executable = script /usr/local/bin/quotawarning.py unix_listener quota-warning { mode = 0666 user = fumail } user = fumail } service replicator { process_min_avail = 1 } ssl_cert = </etc/ssl/<munged>.crt ssl_key = </etc/ssl/<munged>.key userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { imap_client_workarounds = mail_plugins = " quota notify replication acl imap_acl quota imap_quota" } protocol pop3 { mail_plugins = " quota notify replication quota" pop3_uidl_format = %08Xu%08Xv } protocol sieve { managesieve_logout_format = bytes ( in=%i : out=%o ) } protocol lmtp { deliver_log_format = from=<%f> msgid=%m action=<%$> subject=%s mail_plugins = " quota notify replication sieve quota" postmaster_address = postmaster@<munged> quota_full_tempfail = yes } -- message transmitted on 100% recycled electrons

I use PAM because of the easyness of blocking specific validated users - you can just add/remove them in a plain text file. Easy administration will be necessary because of the planned huge amount of users on the system (28.000), and sometimes blocking a user is highly time-dependent (e.g. if one answers to a phising mail and sending out his credentials which are then abused for sending spam). I would go over LDAP if there is an equivalent easy way to solve this over LDAP (easy blocking out users by e.g editing a plain text file) - is there any?

[Dovecot] 2.2.rc2: problem with acl_shared_dict
by Lutz Preßler 22 Mar '13

22 Mar '13

Hello, 2.2.rc2, configuration as before: acl_shared_dict=file:... The contents of this file is used for e.g. LISTing shared mailboxes. But even with file and directory beeing world writable, it's not written into on SETACL commands. Instead, at least sometimes (it seems to make a difference if GETACL is used before in the session) the imap process crashes on SETACL or DELETEACL. Feb 26 00:31:52 host dovecot: imap(13373, user) K64y8ZTWOgB/AAAB: Fatal: master: service(imap): child 13373 killed with signal 11 (core dumps disabled) Anything to do for further debugging? Working correctly with 2.1.15. Greetings, Lutz

[Dovecot] director's imap/pop3 login timeout
by Angel L. Mateo 21 Mar '13

21 Mar '13

Hello, We have two (load balanced) director servers in front of 4 dovecot backend servers. Yesterday we had a problem at backend servers for some users (our SSO was down, so IMAP users couldn't authenticate) and this triggered a problem in director servers where almost nobody could open a new session. In our director's logs I could see errors like this: Mar 20 20:52:47 myotis41 dovecot: imap-login: proxy(<user>): Login failed to 155.54.211.162:143: [UNAVAILABLE] Temporary authentication failure. [myotis32:2013-03-20 19:52:47] So, it seems it was trying to authenticate for 1 hour, after that it timed out the login. But this timeout is too long. Is this a director timeout? Or a backend timeout? How can I reduce it? -- Angel L.

[Dovecot] Log DNS revese IP address

Hi list. Is it possible to log the DNS reverse address of every login? I didnt find a variable *%{hostname}* but the wiki say it only works on *deliver_log_format* and not on *login_log_format_elements* Something like this: Mar 21 13:49:33 mailserver dovecot: pop3-login: Login: user=<myuser>, method=PLAIN, rip=10.10.10.15, lip=10.10.10.1, mpid=18712, *host=client02.example.com* Thanks!

Hi, I have set up ImapcProxy based on the wiki2 page. My server is set up for no plain text auth without starttls. When I am trying to login in the proxy server, I am getting an error Unknown username/password. The log says: *dovecot: imap-login: Aborted login (auth failed, 1 attempts in 2 secs): user=<xxx>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, TLS, session=<1pBG/03XogB/AAAB>* The server log: *dovecot: imap-login: Disconnected (tried to use disabled plaintext auth): rip=10.x.x.x, lip=10.x.x.y* Through wireshark, I found the username and password is going in plain text only to the server. How will I enable starttls in ImapcProxy before any communication starts?

[Dovecot] Problem with Prefetch User Database
by megodin＠inboxalias.com 21 Mar '13

21 Mar '13

Hi there Community, I am currently setting up a Dovecot Mailserver, which works fine with some basic configuration (Dovecot + Sendmail). Sending and receiving Mails is just fine. For improving timings, I wanted to activate the prefetch user database - but apparently it doesn't seem to work correctly - I hope you can help me out! When I activate the prefetch user database, every time I get a "passdb didn't return userdb entries" from my mail.debug logs. Here's my config: passdb { driver = pam } # (I authenticate via PAM which is itself configured to ask ldap server, ldap returns it back to PAM - so Dovecot only sees the PAM-authentication part) userdb { driver = prefetch } userdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } # My userdb is going over ldap. Relevant parts of /etc/dovecot/dovecot-ldap.conf.ext: . .. user_attrs = uidNumber=50014,gidNumber=2084,modem-quota=quota_rule=*:storage=%$ user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uidNumber==50014,gidNumber=2084 I'm not sure.... maybe it's because of the PAMLDAPPAM? Or am I missing out something other fundamental? Thanks for any insights, Megodin --- Alle PostfÃ¤cher an einem Ort.

[Dovecot] dovecot: auth-worker: order of authentication types
by David Obando 20 Mar '13

20 Mar '13

Hi all, I'm setting a mailserver using dovecot version: 2.1.7. On the server I have a couple of system users using PAM authentication and a lot of virtual users using SQL authentication. When a virtual user (e.g. david(a)virtdomain.de) logs in dovecot tries to authenticate the user via PAM and after failing it uses SQL: Mar 19 11:39:42 orange dovecot: auth-worker(7815): pam(david(a)virtdomain.de,<ip address>): pam_authenticate() failed: Authentication failure (password mismatch?) Mar 19 11:39:42 orange dovecot: auth: passwd(david(a)virtdomain.de,<ip address>,<T58IuUTYvgDZbill>): unknown user Mar 19 11:39:42 orange dovecot: imap-login: Login: user=<david(a)virtdomain.de>, method=PLAIN, rip=<...>, lip=<...>, mpid=7816, TLS Could I set up dovecot authentication so *users that authenticate with only their username (i.e. system users) always and only use PAM authentication *users that authenticate with their e-mail-address always and only use SQL authentication ???

[Dovecot] Override quota settings with LDAP
by Hanno Hirschberger 20 Mar '13

20 Mar '13

Hi all, my current Dovecot setup is fetching both the imap quota limit and the mail location settings from LDAP entries. user_attrs = [...] UDBmailQuota=quota_rule=*:bytes=%$, mailLocation=mail That is because we have 3 users who wants to fetch their mail from /var/mail/<username>. All the other users have maildir with maildir quota. The LDAP entry for /var/mail user looks like this: mailLocation: mbox:/var/empty:INBOX=/var/mail/<username>:INDEX=MEMORY Works fine with one exception: the mail quota for /var/mail users. The dovecot log gets spammed with: Mar 20 13:37:04 lmtp(2494, username): Warning: quota: Namespace '' is not Maildir, skipping for Maildir++ quota Mar 20 13:37:04 lmtp(2494, username): Error: opendir(/var/empty/.imap) failed: No such file or directory ... which is only logical, because there's no maildir for that user. I want to get rid of these error messages and like to ask you if there's a way to override the "quota = maildir:User quota" setting in my Dovecot configuration for the 3 /var/mail users. For example with an extra LDAP field? Sadly I don't really know how to realize this. Or is there any other / better way? You can look at my doveconf -n output here: http://pastebin.com/mJZ2CXbg Best regards, Hanno

[Dovecot] shared folders and "subscriptions = yes"
by Lars Uhlmann 20 Mar '13

20 Mar '13

Example (dovecot 1.2.15): ,-[dovecot.conf] | namespace public { | separator = / | prefix = management | location = maildir:/path/to/management | subscriptions = yes | } | | namespace public { | separator = / | prefix = sales | location = maildir:/path/to/sales | subscriptions = yes | } `----- To have all IMAP-Users automatically updated their shared folder structure I use "subscriptions = yes". This works with the side effect, that all IMAP-Users can see _all_ folders in every namespace even if they do not have "lookup" access. This is of course not wanted. Is it possible to have dovecot check the ACL file in the root of a namespace before it parses the subscrptions file? regards Lars

[Dovecot] dsync migration questions
by Michael Smith (DF) 20 Mar '13

20 Mar '13

We are currently in the process of replacing one of our customer mail systems with a dovecot solution. However, one of the sticking points right now is how to get the old mail to the new system. On the dovecot side, we are using mdbox storage. On the old system we are using qpopper/mbox mailboxes in the following setup. All user inboxes are in /mnt/mail/mail_spool. Only select, privileged, users have mail folders in /mnt/mail/mail_spool/FOLDERS/user/. I know, insane setup, but it's almost 18 years legacy now. Like this... /mnt/mail/mail_spool/user1.mbox /mnt/mail/mail_spool/user2.mbox /mnt/mail/mail_spool/user3.mbox /mnt/mail/mail_spool/user4.mbox /mnt/mail/mail_spool/FOLDERS/user2/folder1.mbox /mnt/mail/mail_spool/FOLDERS/user2/folder2.mbox Also, the UIDs between the old system and the new dovecot solution are different. User1 may have uid 2134 on the old system, but have uid 193847 on the new system. We've tried the following. Note: User Anakin has a single message already in the new inbox. mkdir -p /mnt/mail/mail_spool/.migrate/ ln /mnt/mail/mail_spool/anakin /mnt/mail/mail_spool/.migrate/inbox chmod 644 /mnt/mail/mail_spool/.migrate/inbox dsync -D -v -R -u anakin(a)domain.com backup mbox:/mnt/mail/mail_spool/.migrate/ ... chmod 600 /mnt/mail/mail_spool/.migrate/inbox /bin/rm -rf /mnt/mail/mail_spool/.migrate dsync(root): Debug: Loading modules from directory: /usr/lib64/dovecot dsync(root): Debug: Module loaded: /usr/lib64/dovecot/lib10_quota_plugin.so dsync(root): Debug: Module loaded: /usr/lib64/dovecot/lib20_zlib_plugin.so dsync(root): Debug: auth input: anakin uid=1000001228 gid=1000001228 home=/var/spool/mail/CC/1000001228 quota_rule=*:storage=0:messages=0 dsync(root): Debug: Added userdb setting: plugin/quota_rule=*:storage=0:messages=0 dsync(root): Debug: Effective uid=1000001228, gid=1000001228, home=/var/spool/mail/CC/1000001228 dsync(root): Debug: Quota root: name=User quota backend=dict args=:file:/var/spool/mail/CC/1000001228/dovecot.quota dsync(root): Debug: Quota rule: root=User quota mailbox=* bytes=0 messages=0 dsync(root): Debug: dict quota: user=anakin, uri=file:/var/spool/mail/CC/1000001228/dovecot.quota, noenforcing=0 dsync(root): Debug: fs: root=/var/spool/mail/CC/1000001228/mail, index=/var/spool/mail/CC/1000001228/index, control=, inbox= dsync(root): Debug: Namespace : Using permissions from /var/spool/mail/CC/1000001228/mail: mode=0700 gid=-1 dsync(root): Debug: Effective uid=1000001228, gid=1000001228, home=/var/spool/mail/CC/1000001228 dsync(root): Debug: Quota root: name=User quota backend=dict args=:file:/var/spool/mail/CC/1000001228/dovecot.quota dsync(root): Debug: Quota rule: root=User quota mailbox=* bytes=0 messages=0 dsync(root): Debug: dict quota: user=anakin, uri=file:/var/spool/mail/CC/1000001228/dovecot.quota, noenforcing=0 dsync(root): Debug: mbox: INBOX defaulted to /mnt/test/mail_spool/.migrate/inbox dsync(root): Debug: fs: root=/mnt/test/mail_spool/.migrate, index=, control=, inbox=/mnt/test/mail_spool/.migrate/inbox dsync(anakin): Debug: Namespace : Using permissions from /mnt/test/mail_spool/.migrate: mode=0777 gid=-1 dsync(anakin): Error: Can't delete mailbox INBOX: INBOX can't be deleted. dsync(anakin): Debug: Namespace : Permission lookup failed from /var/spool/mail/CC/1000001228/mail/mailboxes/INBOX_b6845831821c42517c490000a72406a4 dsync(anakin): Debug: Namespace : Using permissions from /var/spool/mail/CC/1000001228/mail: mode=0700 gid=-1 dsync(anakin): Debug: Namespace : Permission lookup failed from /var/spool/mail/CC/1000001228/mail/mailboxes/INBOX_b6845831821c42517c490000a72406a4 dsync(anakin): Debug: Namespace : Using permissions from /var/spool/mail/CC/1000001228/mail: mode=0700 gid=-1 dsync(anakin): Info: INBOX: only in dest dsync(anakin): Info: INBOX: only in source dsync(anakin): Error: Trying to open a non-listed mailbox with guid=814b6332541c425169490000a72406a4 dsync(anakin): Error: msg iteration failed: Couldn't open mailbox 814b6332541c425169490000a72406a4 dsync(anakin): Error: Trying to open a non-listed mailbox with guid=814b6332541c425169490000a72406a4 Nothing was migrated. In some other combinations, trying to reproduce them again, it does migrate the old mail, but first destroys the existing mail in the new mailbox. Our goal is to cut mail delivery over to the new dovecot system (which will result in existing emails before migration), and then migrate the old mail *while* maintaining message UIDs. This is the easiest way to ensure no "lost" email with the migration. What are we doing wrong, and how do we achieve our goals? Thanks in advance. -- Michael Smith

[Dovecot] Logon with Client Certificate and OTP fallback
by dovecot.pkoch＠dfgh.net 20 Mar '13

20 Mar '13

Dear Dovecot experts, we have unusual authentication requirements, namely: - almost all of our user are using a smartcard to connect with our mailserver. Thunderbird is our friend here as it will use the smartcard as an additional certificate store and Thunderbird will do client certificate based authentication when connecting via SSL with a mailserver - there's no way (at least that I know of) for our iPad users to use a smartcard, so our iPad and iPhone users use OTP token (http://www.gooze.eu/catalog/otp-tokens-oath-0) For 10 years we are using a very simple POP3-server where I replaced the authentication routines with my own functions and these function are doing the following: 1) if the connection was made without SSL refuse to connect 2) if the client was using a client certificate extract the username from the certificate. Since we cannot stop Thunderbird from sending a username/passowrd-combination we compare the username from the certificate with the username Thunderbird has sent. If the usernames matches we allow access and ignore the password. 3) if the client did not sent a client certificate we calculate the current OneTimePassword of the users OTP-token and compare that with the password Thunderbird has sent. If the passwords matches we allow access. If a OTP-password was validated it can be used for 24 hours so our OTP-users must use their tokens only once a day. Now we would like to switch from POP3 to IMAP, so here are my questions: - can Dovecot be CONFIGURED to do the above. I compiled it yesterday and SSL client authentication works as expected. OTP seems to be supported via PAM and I can write a PAM-modul for our OTP-tokens, so OTP would be possible too. But how do I tell Dovecot to do OTP-auth as a fallback for ClientCert-auth. - I already looked into the sourcecode of Dovecot. Seems like all the authentication routines were built as pluggable modules. Is there any documentation out there on how how to built my own auth-module. Integrating the OTP-auth directly into Dovecot would be a lot easier (for me) than creating a PAM-module, so I would prefer that. If there was interest from other people I would add some configuration options to Dovecot (for example the location of the OTP-token list). Otherwise I would just hardcode everything into the source.

[Dovecot] ACL to make mailboxes populated by master account Read Only for regular users.
by Alex Cherniak 20 Mar '13

20 Mar '13

We have a solution using Dovecot as a secondary mail archive. All mailboxes are populated/groomed by master account and the actual users have only read access. This is achieved by a simple ACL approach. dovecot.conf has protocol imap { mail_plugins = acl quota imap_quota zlib } plugin { acl = vfile:/etc/dovecot/acls:cache_secs=300 } /etc/dovecot/acls/.DEFAULT file is trivial: user=master lrwstipekxa owner lr It used to work with Dovecot 2.0.4 for years, but after upgrade to 2.0.18 users now have full access to folders created by master account and can delete, add and move mails. Should it behave this way? How can I "secure" mailboxes again? Any help is appreciated.

[Dovecot] Lot of dovecot process writes

Hello, While monitoring my servers' behaviour (ubuntu 12.04 with dovecot 2.1.9, with about 70000 users) I have found that lots of disk usage is done by dovecot process (the parent process). Since lmtp, imap and pop3 connections are handle by their own process, what could be the reason of this? -- Angel L.

[Dovecot] Maildir or Mdbox and expunge messages.
by Evgeny Basov 20 Mar '13

20 Mar '13

Hello. I tested dovecot's work with expunge messages on Mdbox over strace (see at tail of message). As I can see dovecot process opens old storage m.* file, reads it content, opens new temporary file, writes in this one content and rename this new one to m.(*+1). How fast this algorithm works on system with about 10000 users and 5Tb data? I will use mdbox_rotate_interval for delayed expunge but I think that simple delete file in Maildir must be faster than expunge from Mdbox. Please, tell me about real experience work with Mdbox on big loaded systems. ++++++++++++++++ 0.000017 open("/var/vmail/example.org/user/storage/.temp.1362474108.P7152Q0M909647.mailsys", O_RDWR|O_CREAT|O_TRUNC, 0666) = 11 0.000063 umask(077) = 066 0.000015 fallocate(11, 01, 0, 10485760) = 0 0.000054 fstat(11, {st_mode=S_IFREG|0600, st_size=0, ...}) = 0 0.000043 pread(10, "\1\2N 0000000000000285\nFC"..., 8192, 16) = 1465 0.000025 write(11, "2 M1e C5135b47c\n\1\2N 000"..., 691) = 691 0.000041 stat("/var/vmail/example.org/user/indexes/storage/dovecot.map.index.log.2", 0x7fff235b34c0) = -1 ENOENT (No such file or directory) 0.000026 alarm(180) = 0 0.000018 fcntl(9, F_SETLKW, {type=F_WRLCK, whence=SEEK_SET, start=0, len=0}) = 0 0.000020 alarm(0) = 180 0.000018 stat("/var/vmail/example.org/user/indexes/storage/dovecot.map.index.log", {st_mode=S_IFREG|0600, st_size=3656, ...}) = 0 0.000031 fstat(9, {st_mode=S_IFREG|0600, st_size=3656, ...}) = 0 0.000041 write(11, "\n\1\3\nR5135ad97\nV29b\nG5840870697ad"..., 62) = 62 0.000023 fdatasync(11) = 0 0.079275 stat("/var/vmail/example.org/user/storage/m.8", 0x7fff235b3640) = -1 ENOENT (No such file or directory) 0.000061 rename("/var/vmail/example.org/user/storage/.temp.1362474108.P7152Q0M909647.mailsys", "/var/vmail/example.org/user/storage/m.8") = 0 0.000164 write(9, "\200\200\200\203\0\0\10\20\210\0\0\0\200\200\200\207@\0\0\20\0\0\0\0\0\0\0\0\10\0\0\0"..., 152) = 152 0.000094 fcntl(9, F_SETLK, {type=F_UNLCK, whence=SEEK_SET, start=0, len=0}) = 0 0.000042 unlink("/var/vmail/example.org/user/storage/m.7") = 0 0.000059 stat("/var/vmail/example.org/user/indexes/storage/dovecot.map.index.log", {st_mode=S_IFREG|0600, st_size=3808, ...}) = 0 0.000055 fstat(9, {st_mode=S_IFREG|0600, st_size=3808, ...}) = 0

[Dovecot] Stability of extraction of attachment

Hello, We are migrating our dovecot servers from 2.1.9 to 2.1.15 (or 2.2 if there is a stable version soon) and maildir format to mdbox. Looking for mdbox options I have found options: * mail_attachment_dir * mail_attachement_min_size * mail_attachment_fs * mail_attachment_hash but this options are described with the message: # WARNING: This feature hasn't been tested much yet. Use at your own risk. What is the state of these options? Could I use it in a production environment? In case of yes, what is the best deduplicating option? Let it to the FS? Or configuring with "sis posix" or "sis-queue posix"? -- Angel L.

[Dovecot] Exposing masteruser info to cllients via lmtp-proxy connections
by Alexandr Sabitov 20 Mar '13

20 Mar '13

Hello, Please somebody suggest me how to remove the "*masteruser" appendix from the dovecot director database while using masteruser authentication. My situation is: - all users get authenticated in LDAP on the dovecot-director frontend - then they are forwarded to dovecot backend as username*masteruser ( this is a way how to proxy users with encrypted passwords). To enable it a added an extra field in LDAP-dovecot configuration: destuser=%u*masteruser This works OK, but problems are: - I have lmtp-proxy on the dovecot frontend and I have to use the same "%u*masteruser" field in lmtp passdb because the director thinks that me(a)mail.com and me(a)mail.com*masteruser are different users and would send lmtp-proxy connections to other dovecot backend. Here is a problem: "Delivery-To" and "Received" fields in any email contains "*masteruser" ! I need to remove any mentions about "masteruser" authentication from client emails. Also another little problem: - If I run "doveadm status" tool then to get user's data I need to specify user as "username*masteruser" Thank you in advance. Alexandr Sabitov Netregistry

[Dovecot] v2.2 status update
by Timo Sirainen 20 Mar '13

20 Mar '13

So, I'm still planning on getting v2.2.0 out Really Soon now. Unfortunately I've had to quickly develop some rather large features still at this stage. I was initially planning on leaving them for v2.3, but they were a requirement for one project and implementing them now to v2.2 was the least amount of trouble for me. (And yes, I'm aware I haven't replied to a lot of emails in this list. There are about 60 unread ones. Hopefully I'll have time to go through them this week.) So, what we have now: * dsync can sync ACLs * dsync can sync Sieve scripts - Slightly unfinished patch for Pigeonhole at http://dovecot.org/patches/2.2/doveadm-sieve-plugin.diff * dsync does the ACL/Sieve syncing by having implemented generic mailbox attribute syncing. (The ACLs/Sieve scripts are transparently mapped into the attribute hierarchy.) ACL plugin also supports now restricting attribute set/get/iteration. IMAP METADATA extension can be implemented using mailbox attributes. The dsync/ACL support was the main reason why I had planned on delaying native IMAP METADATA support until v2.3, but there's really no reason for that anymore. So expect IMAP METADATA support also early in v2.2.x (disabled by default). I'll still need to figure out how to do quota for it. * LDAP values can now have DN pointers to other entries that are queried. (Support for LDAP URLs could probably also be added with little trouble.) The configuration becomes a bit more complex again, but until the whole LDAP configuration is redesigned this will work. Example: user_attrs = \ =user=%{ldap:uid}, \ @mail=%{ldap:mailDN}, \ =uid=%{ldap:uidNumber@mail}, \ =gid=%{ldap:gidNumber@mail}, \ =home=%{ldap:rootPath@mail}/%d/%n
