Using dovecot to serve an email archive
by Ramón Casares 06 Apr '15

06 Apr '15

I have a collection of old email messages, archived as follows: 1) One file per message. 2) Messages (=files) distributed in a hierarchy of dirs under mailarch. 3) Each file (=message) uses the name <seconds>.R<sha1>.mail Here <seconds> is the date of the message, expressed as the number of seconds from 1-1-1970 00:00 in 10 digits, and <sha1> is the SHA-1 hash of the message contents, expressed in hexadecimal, [0-9a-f]. The advantages of this file naming scheme are: 1) All important metadata are in the file name. 2) You can verify the integrity of each message using only its own data and metadata. 3) Each file name is unique. 4) It is compatible with maildir (qmail) unique names (uniq). 5) If a dir is sorted alphabetically, then it is ordered chronologically. 6) The extension .mail can be used to call an appropriate message reader. >From time to time I add new messages and dirs to the archive, but some dirs are closed forever, so it would be nice to tar.gz'ip them. Now I am looking for an IMAP server that can serve this collection in a read-only (ro) manner. That is, the server should not write the mailarch dir at all. I am exploring two possibilities: 1) using hard links. 2) using FUSE to set a rw layer on top of the ro archive layer. But I am new to dovecot, so perhaps there is an easier way to achieve what I want, and therefore I would appreciate very much your advice.

Sieve/ManageSieve documentation on Wiki2
by Robert Blayzor 06 Apr '15

06 Apr '15

Is it possible the Sieve/ManageSieve documentation on the Wiki can be cleaned up? It's incredibly confusing now. Some of the Sieve configuration information says certain options are deprecated, but then the example on how to configure it uses the deprecated options rather than what they *should* be now. More confusion is the sieve plugin configuration listing those same deprecated options, yet when you pull the document on how to configure ManageSieve, it (again) uses deprecated configuration information? http://wiki2.dovecot.org/Pigeonhole/ManageSieve/Configuration Or am I missing something? -- Robert inoc.net!rblayzor http://inoc.net/

IMAP logging / rawlog
by G H 06 Apr '15

06 Apr '15

I am trying to monitor with Nagios that my phones are consistently checking into dovecot via IMAP. I used to be able to parse syslog for imap-login messages. I have since updated my phones, the phoness email client (k9-mail) and dovecot. Now the imap-login messages are few and far between. However, I can clearly see via tcpdump that some traffic is happening when I click refresh on k9. I enabled "rawlog" support in dovecot, but it doesn't seem to write to disc frequently enough. 1) Does anyone have a better suggestion for how to monitor that my phone is checking in regularly? 2) Is there a flush-to-disk capability for rawlog in dovecot? 3) Also, when you have imap_zlib plugin enabled, the rawlog logs the raw compressed data instead of the decompressed IMAP commands. Is this an oversight? (FYI: k9 is calling SELECT "INBOX" on refresh) Thanks, G H

Question About Dovadm syntax
by Kenneth Ulrich 06 Apr '15

06 Apr '15

Hello All, I just have a quick question about doveadm commands. 1. Is there a command that we can use to count emails for a particular end user? 2. If an end user needed to copy/move emails from one account to another, is there a command? Also, I've searched Google results, numerous Ubuntu, CentOS, Fedora forums, Doveadm forums, and read the DoveCot/DoveADM man pages numerous times and either I am over looking, or I am not understanding. Thus why I am asking here.

speaking of sieve scripts... how to selectively not send vacation autoreply
by Harondel J. Sibble 04 Apr '15

04 Apr '15

Don't need to block anyone like in the "Re: Dovecot Oy merger with Open-Xchange AG" thread, but when I have my vacation recipie active, I'd like it to NOT reply to certain addresses. I tried the following, you can see the section with if header :contains "addressIdontwant(a)repliedtoo.tld" is commented out, once I'd added that section, no Vacation messages went out at all. Googling and reading the wiki and recipie suggestions doesn't make it clear how to exempt a list of addresses from ever receiving a vacation response. Suggestions on additional reading or solutions? require ["fileinto", "vacation"]; if header :comparator "i;ascii-casemap" :contains "Subject" "**SPAM**" { fileinto "Trash"; stop; } #if header :contains "addressIdontwant(a)repliedtoo.tld" { # stop; #} vacation # Reply at most once a day to a same sender :days 1 :subject "Changes to email addresses effective Jan 01/15" # List of recipient addresses which are included in the auto replying. # If a mail's recipient is not on this list, no vacation reply is sent for it. :addresses ["user(a)repliedtoo.tld"] This is on a Dovecot 1.x system that is slated for an upgrade soon. -- Harondel J.

Dovecot Oy merger with Open-Xchange AG
by Timo Sirainen 03 Apr '15

03 Apr '15

Hi all, Today I can finally announce that Dovecot Oy company has merged with Open-Xchange AG. This helps us to get more Dovecot developers, support people and so on. Most importantly, eventually it should allow me to get back to doing what I like the most: Designing new and interesting stuff for Dovecot and perfecting the old stuff :) OX is a great match to Dovecot going forward. They also really like open source and share our plans for the future. Nothing big will change as a result of this merger: Dovecot will stay Dovecot with its own name and release schedules. We're not going to force OX and Dovecot to be the same product, other than having a somewhat deeper integration between them. Here are the press release links about it: http://www.dovecot.fi/open-xchange-and-dovecot-announce-merger-to-create-wo… http://www.open-xchange.com/dovecot http://www.open-xchange.com/announcements/18

EL6 EE package dependencies
by Will Yardley 03 Apr '15

03 Apr '15

I've been trying to upgrade Dovecot-ee package (on EL6/x86_64) from 2.2.15.8-1 to 2.2.16.2-1. It's complaining on these two dependencies: liblz4.so.1 libtextcat.so.0 These would both seem to be related to plugins, and don't seem to be required as package dependencies by the RPM from what I can see from the SRPM. Anyone know what packages I need to satisfy these dependencies?

Install process breaks its self by design
by Merlin at Desktop Masters 02 Apr '15

02 Apr '15

Greetings, I just tried to install Dovecot for the first time. It was on a virgin Ubuntu/Debian server (Version: 1:2.2.9-1ubuntu5) and the install failed. After a bit of struggling I worked out that the install fails BY DESIGN. Spoke about this with a few people and we decided it was best to report this issue and request that you redesign the packing so it does not fail. The reason it fails is as follows... When you install it asks you if you want to use self signed certificates. I have certificates so I said, "No". At the end of the install the script tries to start dovecot. It cannot because the service does not have certificates so it fails. This causes the script to abort and the other packages not to install and breaks the install process. I had to purge dovecot, then install it with the self signed certificates. So we have 2 issues here. 1. Why allow people to not install certificates if it is just going to break the install and confuse them. 2. Why are you starting the service right after install when dovecot clearly requires manual configuration as part of the setup. I recommend you resolve this by NOT starting the service as part of the install unless it is an upgrade and the service was already running. ~ Merlin

Hi I do not understand the right configuration I had a loop worries the users received the same message multiple times and testing other users config was not found so what is the right config to the following scheme My ldap scheme : mail: jf(a)marche.be gosaMailForwardingAddress: jf(a)citoyen.marche.be gosaMailAlternateAddress: toto(a)marche.be dovecot-ldap.conf.ext user_filter = (&(objectClass=posixAccount)(uid=%n)) virtual_mailbox_maps = proxy:ldap:/etc/postfix/ldap_virtual_recipients.cf virtual_alias_maps = proxy:ldap:/etc/postfix/ldap_virtual_recipients.cf ldap_virtual_recipients.cf : server_host = localhost search_base = ou=Users,ou=Citoyens,dc=marche,dc=be scope = sub bind = no version = 3 query_filter = (&(|(mail=%s)(gosaMailAlternateAddress=%s)(gosaMailForwardingAddress=%s)(uid=%s))(objectClass=gosaMailAccount)) result_attribute = uid is it correct ? thanks

Migrating from Cyrus to Dovecot
by Miloslav Hůla 31 Mar '15

31 Mar '15

Hi, we are migrating from Cyrus 2.3.7 to Dovecot 2.2.13. We have ~7000 maildirs with ~500GB. Our goal is to do the migration without users have notice and with the shortest service downtime. The users use IMAP (with shared folders and ACL), POP3 and sieve filters. As a first choice, we tried the Dovecot's dsync tool. First tests were great, but we are not able to change the Cyrus auth backend for migration. Moreover, this migration seems too slow for us. As a second try, we tried the cyrus2dovecot migrating Perl scripts (and their derivates) from Wiki2. More or less they works but we found we need more control during the migration. So, as a third try, we wrote own migrating scripts. And thanks to the cyrus2dovecot it wasn't too much complicated. And there are my questions: A) Files and dirs timestamps The mtime of email file is important as an internal date as I found on Wiki2. But what about timestamps of cur/new/tmp directories or Dovecot's internal files line dovecot-uidlist? Do they play some role here? B) The 128 bit mailbox UID The Wiki2 speaks about 128 bit mailbox UID at first line of dovecot-uidlist. Cyrus preserves only 64 bit UID. Is this mailbox UID required by Dovecot? If so, can we use 0000000000000000501100008c4a11c1 (Cyrus UID padded by zeros)? C) Format of dovecot-uidlist records Wiki2 shows two examples: 25006 :1276528487.M364837P9451.kurkku,S=1355,W=1394:2, 25017 W2481 :1276533073.M242911P3632.kurkku:2,F Which format is preferred? Or what the benefits are? D) Converting between CRLF and LF If I understand correctly, Dovecot stores emails with LF only. We have all emails with CRLF now on Cyrus and converting them to LF only is a little more time consuming. Is there any benefit to do that? Or can we live with 'mail_save_crlf' without problems? E) POP3 backend I found many informations about IMAP internals but few on POP3 internals. What do I need to do POP3 migration transparent for user? Many thanks for any answers. Regards, Milo

quota setup assistance (postfix+dovecot+mysql)
by rooster 31 Mar '15

Hello list, I have been struggling with establishing a working installation of dovecot with mySQL quota support. I have not been able to find a guide or tutorial that works for the current revisions of software I have at my disposal. Most notably, the error I see in the mail log is as follows : Mar 23 00:55:31 host dovecot: lmtp(328): Debug: Module loaded: /usr/lib/dovecot/modules/lib10_quota_plugin.so Mar 23 00:55:31 host dovecot: lmtp(328): Error: dlopen(/usr/lib/dovecot/modules/lib11_imap_quota_plugin.so) failed: /usr/lib/dovecot/modules/lib11_imap_quota_plugin.so: undefined symbol: command_unregister Mar 23 00:55:31 host dovecot: lmtp(328): Fatal: Couldn't load required plugins I have attached my dovecot -n output. The installed revision of dovecot is 2.2.9 on ubuntu 14.04.02 LTS. Thank you in advance. --

sieve rule for "header don't exist"
by Reindl Harald 30 Mar '15

30 Mar '15

is there a way to expresse when the header "X-Spam-Status" *do not* exist move the message to a different folder? :contains, :matches and :is are not helpful here background: the spamass-milter option -B is lacking the spamassassin headers in case of milter-rejects and via sendmail generated BCC while flagged messages contain the headers - so it would be nice to move the rejected ones to a subfolder "REJECTED" instead into the inbox

Error after setting up fts /solr for Open-Xchange

v2.2.16 released
by Timo Sirainen 28 Mar '15

28 Mar '15

http://dovecot.org/releases/2.2/dovecot-2.2.16.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.16.tar.gz.sig A few fixes and some imapc improvements since the release candidate. * dbox: Resyncing (e.g. doveadm force-resync) no longer deletes dovecot.index.cache file. The cache file was rarely the problem so this just caused unnecessary slowness. * Mailbox name limits changed during mailbox creation: Each part of a hierarchical name (e.g. "x" or "y" in "x/y") can now be up to 255 chars long (instead of 200). This also reduces the max number of hierarchical levels to 16 (instead of 20) to keep the maximum name length 4096 (a common PATH_MAX limit). The 255 char limit is hopefully large enough for migrations from all existing systems. It's also the limit on many filesystems. + director: Added director_consistent_hashing setting to enable consistent hashing (instead of the mostly-random MD5 hashing). This causes fewer user moves between backends when backend counts are changed, which may improve performance (mainly due to caching). + director: Added support for "tags", which allows one director ring to serve multiple backend clusters with different sets of users. + LMTP server: Added lmtp_user_concurrency_limit setting to limit how many LMTP deliveries can be done concurrently for a single user. + LMTP server: Added support for STARTTLS command. + If logging data is generated faster than it can be written, log a warning about it and show information about it in log process's process title in ps output. Also don't allow a single service to flood too long at the cost of delaying other services' logging. + stats: Added support for getting global statistics. + stats: Use the same session IDs as the rest of Dovecot. + stats: Plugins can now create their own statistics fields + doveadm server: Non-mail related commands can now also be used via doveadm server (TCP socket). + doveadm proxying: passdb lookup can now override doveadm_port and change the username. + doveadm: Search query supports now "oldestonly" parameter to stop immediately on the first non-match. This can be used to optimize: doveadm expunge mailbox Trash savedbefore 30d oldestonly + doveadm: Added "save" command to directly save mails to specified mailbox (bypassing Sieve). + doveadm fetch: Added body.snippet field, which returns the first 100 chars of a message without whitespace or HTML tags. The result is stored into dovecot.index.cache, so it can be fetched efficiently. + dsync: Added -t <timestamp> parameter to sync only mails newer than the given received-timestamp. + dsync: Added -F [-]<flag> parameter to sync only mails with[out] the given flag/keyword. + dsync: Added -a <mailbox> parameter to specify the virtual mailbox containing user's all mails. If this mailbox is already found to contain the wanted mail (by its GUID), the message is copied from there instead of being re-saved. (This isn't efficient enough yet for incremental replication.) + dsync: -m parameter can now specify \Special-use names for mailboxes. + imapc: Added imapc_features=gmail-migration to help migrations from GMail. See http://wiki2.dovecot.org/Migration/Gmail + imapc: Added imapc_features=search to support IMAP SEARCH command. (Currently requires ESEARCH support from remote server.) + expire plugin: Added expire_cache=yes setting to cache most of the database lookups in dovecot index files. + quota: If overquota-flag in userdb doesn't match the current quota usage, execute a configured script. + redis dict: Added support for expiring keys (:expire_secs=n) and specifying the database number (:db=n) - auth: Don't crash if master user login is attempted without any configured master=yes passdbs - Parsing UTF-8 text for mails could have caused broken results sometimes if buffering was split in the middle of a UTF-8 character. This affected at least searching messages. - String sanitization for some logged output wasn't done properly: UTF-8 text could have been truncated wrongly or the truncation may not have happened at all. - fts-lucene: Lookups from virtual mailbox consisting of over 32 physical mailboxes could have caused crashes.

postfix sasl -> haproxy -> dovecot auth
by Edgaras Lukoševičius 28 Mar '15

28 Mar '15

Hello, is it possible to configure configure haproxy to work with postfix sasl and dovecot auth like this: clients -> 25:postfix -> 20025:haproxy -> 20025:auth-backend-1, 20025:auth-backend-2 The configuration I have now gives me this error randomly: 535 5.7.8 Error: authentication failed: Connection lost to authentication server This is probably because haproxy change servers while session is still active (postfix sasl don’t establish new connection to auth service every time new auth request arrives) Note that haproxy is between postfix and dovecot and is not facing clients directly, so there is no way to keep persistent connections by client ip. # POSTFIX smtpd_sasl_auth_enable = yes smtpd_sasl_authenticated_header = yes smtpd_sasl_exceptions_networks = smtpd_sasl_local_domain = smtpd_sasl_path = inet:127.0.0.1:20025 smtpd_sasl_security_options = noanonymous smtpd_sasl_tls_security_options = $smtpd_sasl_security_options smtpd_sasl_type = dovecot # HAPROX frontend postfix-sasl bind 127.0.0.1:20025 default_backend dovecot-auth backend dovecot-auth mode tcp option tcplog option srvtcpka hash-type consistent balance roundrobin server mail-backend-1 31.220.19.52:20025 check server mail-backend-2 31.220.19.53:20025 check

For example, a mail reader that does local manipulation of mbox files rather than via IMAP. This log message is more or less saying that the indices are out of sync with respect to the mailbox, and the message that it expected to find at a file offset is not there anymore. > Mar 26 09:40:07 raspberrypi dovecot: imap(info): Panic: file > mbox-sync.c: line 1286 (mbox_sync_handle_eof_updates): assertion failed: > (trailer_size <= 2) This, though, should not happen. Your version of dovecot is rather old, so maybe an update will solve this. Joseph Tam <jtam.home(a)gmail.com>

Re: Error: open() failed with file /var/vmail/... Too many open files

I've already tried creating etc/default/dovecot chmod +x it and inside put ulimit but didn't work. Also i've tried to put the ulimit into the /etc/init.d/dovecot linked file but i found still 1024 the limit kn dovecot.

You need to put the ulimit commands somewhere in the init script. Or perhaps adding the ulimit command to /etc/default/dovecot would work. I don't know what's the correct Ubuntu way to do it.

Courier-dovecot migration issue: Forward and Junk flags
by Dennis Højgaard 27 Mar '15

27 Mar '15

Hello.. Another courier -> dovecot migrater here.. I ham having a bit of trouble converting the courier maildir correctly, or actually i'm almost there. The only thing i experience is that forwarded messages and messages marked as junk (in thunderbird) are downloaded again (i am using thunderbird and caching) after running the courier-dovecot-migrate.pl script and connecting to the newly configured dovecot imap server.. So i think that the Forward and Junk flag is not being converted..

IMAP ANNOTATE Extension RFC5257: priority on roadmap
by Florian Sager 27 Mar '15

27 Mar '15

Hi Timo, congrats to the merger with OX. Currently the implementation of RFC 5257, ANNOTATE-EXPERIMENT-1, has only low priority on http://wiki2.dovecot.org/Roadmap I want to explain a scenario that would benefit from annotation support to - maybe - increase the priority in your roadmap: I'm currently working on a project to publish bank customer related documents inside a banking webinterface (they call it 'postbox'). There are different requirements that would be satisfied very well by an IMAP server as data storage/provider for a long term email/document archive inside the bank. Annotations would be necessary to tag emails with customer numbers and document IDs to allow a delayed grouping of several emails by such identifiers (message IDs may not be available for references so annotations have to be used to compute references indirectly). Same for sorting and filtering by customer number or account number. I would highly appreciate if you at Dovecot could increase the priority of ANNOTATE in your roadmap.

You could remove them with sieve in the latest version of pigeonhole. On Mar 24, 2015 7:33 AM, Florent B <florent(a)coppint.com> wrote: > > I know about RFC's, but that could be an option, not enabled by default.

Error "Next message unexpectedly lost from mbox file"
by BehrensM 26 Mar '15

26 Mar '15

Hi, i am the new one;) - and my first post is about a problem i ran into. I installed a mailserver on a RaspberryPi. It works mostly well, using dovecot 2.1.7. (exim4 4.8 (not in use, smtp direct to Provider), fetchmail 6.3.21, RasPi 3.12.28+, Roundcube (no version known) - the whole system went through an apg-get update/uppgrade this night to look if a known problem already been fixed. When getting bigger Attachments (not sure if it occurs by smaller too, but bigger attachments are normally "to open" and often fail) Not all of them, but much. Unpredictable when it occurs. These Attachments are shown with less size in the Mailclient (Thunderbird actual version). In Roundcube they are shown to small, too. But it looks as the mail IS "fullsized" on the lokal Mailserver: When i use Roundcube and try to open an x00kB .zip, Roundcube starts to get the whole xyMB (real size) .zip-file, even when disconnected from internet. Thunderbird behaves different, doesnt load the full file, so "ignore" is no option;) And yes, i always dont like that option:) Beside the lokal mailserver-account(s) there is/are pulled Mails via imap direct from the mailprovider, the "old" solution which shall be replaced by the new mailserver. imap direct from provider shows the mails/Attachments in corrects size an opening works. Only using the local mailserver fails. In the log-files i found (i quote a part in which - cronjob matching - one of these defect mails was pulled): In Syslog: Mar 26 09:40:01 raspberrypi /USR/SBIN/CRON[26696]: (info) CMD (/usr/bin/fetchmail -s --fetchsizelimit 0 --fetchlimit 0 --limit 0 --timeout 300) Mar 26 09:40:05 raspberrypi dovecot: imap(info): Error: Next message unexpectedly lost from mbox file /home/info/mail/.INBOX at 1066141935 (cached) Mar 26 09:40:05 raspberrypi dovecot: imap(info): Error: read(/home/info/mail/.INBOX) failed: Invalid argument (FETCH for mailbox INBOX UID 1247) Mar 26 09:40:05 raspberrypi dovecot: imap(info): Disconnected: Internal error occurred.

The limit 0 and timeout entries are just to test after running into the error and before i discovered that not fetchmail but dovecot looks to cause the problem) In the archive i only found an issue in 2010 with a CR/LF-problem, but it is a) a long time ago an b) i am not sure that my specific problem comes from the same direction. http://www.dovecot.org/list/dovecot/2010-November/054938.html Any suggestions how to solve that problem? Thanks.
