Migration from mbox/maildir++ to mdbox
by Nima Saed-Samii 24 Jul '14

24 Jul '14

Dear list, dovecot version: 2.1.7 I have an old mail server that uses mboxes for the INBOX and maildirs for subfolders. I want to migrate our mail handling to a new setup using mdboxes for everything. The current config looks like this: # 2.1.7: /etc/dovecot/dovecot.conf doveconf: Warning: service anvil { client_limit=1000 } is lower than required under max. load (1127) # OS: Linux 3.2.0-0.bpo.4-686-pae i686 Debian 6.0.10 auth_mechanisms = plain login disable_plaintext_auth = no first_valid_uid = 114 log_path = /var/log/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = mbox:~/Mail/MBox:INBOX=/var/mail/%u mail_max_userip_connections = 30 mail_privileged_group = mail namespace { hidden = yes inbox = yes list = no location = prefix = "#mbox/" separator = / } namespace { location = maildir:~/Mail/Maildir prefix = separator = / } passdb { args = dovecot driver = pam } protocols = imap service auth { client_limit = 1024 user = root } service imap-login { inet_listener imap { port = 0 } process_limit = 1024 } ssl_cert = </etc/ssl/certs/cert-imap.ikp.pem ssl_key = </etc/ssl/private/key-imap.ikp.pem ssl_key_password = ********* userdb { driver = passwd } I would like to use dsync to migrate all to mdboxes and transfer them to the new system. Unfortunately I can't get dsync to do that. Using a config that specifies only one namespace allows me to convert either mboxes or Maildirs to mdboxes but not both. Using the above config dsync somehow thinks the source and destination are the same: Syncing mailbox for user nima (136 MB) Setup done. doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/lib20_zlib_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules/doveadm doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_zlib_plugin.so doveadm(nima): Debug: Effective uid=5224, gid=1162, home=/home/nima doveadm(nima): Debug: Namespace mboxes: type=private, prefix=#mbox/, sep=/, inbox=yes, hidden=no, \ list=yes, subscriptions=yes location=mbox:~/Mail/MBox:INBOX=/var/mail/nima doveadm(nima): Debug: fs: root=/home/nima/Mail/MBox, index=, control=, inbox=/var/mail/nima, alt= doveadm(nima): Debug: Namespace maildirs: type=private, prefix=, sep=/, inbox=no, hidden=no, list=yes, \ subscriptions=yes location=maildir:~/Mail/Maildir doveadm(nima): Debug: maildir++: root=/home/nima/Mail/Maildir, index=, control=, inbox=, alt= dsync(nima): Debug: Effective uid=5224, gid=1162, home=/home/nima dsync(nima): Debug: Namespace mboxes: type=private, prefix=#mbox/, sep=/, inbox=yes, hidden=no, list=yes, \ subscriptions=yes location=mdbox:/scratch/mail-convert/nima dsync(nima): Debug: fs: root=/scratch/mail-convert/nima, index=, control=, inbox=, alt= dsync(nima): Debug: Namespace #mbox/: Using permissions from /scratch/mail-convert/nima: mode=0700 gid=-1 dsync(nima): Debug: Namespace maildirs: type=private, prefix=, sep=/, inbox=no, hidden=no, list=yes, \ subscriptions=yes location=maildir:~/Mail/Maildir dsync(nima): Debug: maildir++: root=/home/nima/Mail/Maildir, index=, control=, inbox=, alt= dsync(nima): Fatal: Both source and destination mail_location points to same directory: /home/nima/Mail/Maildir What am I doing wrong?

doveconf option "-e"
by Django [BOfH] 24 Jul '14

24 Jul '14

Hi Timo, If I could tell you a little smart wish, I've one for you. ;) Today I'm writing my own configurationdocumentation 'bout Dovecot in my dokuwiki and for documentation purposes I changing some options several times a day. Postfix supports on its own postconf an option -e. So I can set up mostly every configuration-option on the fly. Dovecot's doveconf has no such option. So, I changed the configuration-files and reload my dovecot-daemon. It were grait if doveconf has a similar function, like postconf's option "-e". Maybe you can make a little update to doveconf in one of the upcomming releases? ;) Best regards Django -- "Bonnie & Clyde der Postmaster-Szene!" approved by Postfix-God http://wetterstation-pliening.info http://dokuwiki.nausch.org http://wiki.piratenpartei.de/Benutzer:Django

Problems with custom plugin
by Lukas Mika 24 Jul '14

24 Jul '14

Hi everybody, I wrote a plugin for Dovecot 2.1.something which was based on the information found at http://wiki2.dovecot.org/Design/Storage/Plugins and by studying the mail_log plugin. My plugin can be found here: https://github.com/dim-0/dovecot-mbc It takes the notify plugin's information, that a new mailbox has been created (or an old one been renamed) in order to trigger a custom script (which in my case sets default ACLs for shared mailboxes). This plugin went quite well for a while, but then I recently upgraded Dovecot to version 2.2.9 and now I cannot build my plugin anymore. I get two error messages which both describe the same thing: src/mbc-plugin.c: In function ‘mbc_mailbox_create’: /usr/include/dovecot/src/lib/module-context.h:46:67: error: ‘struct mbc_user_module’ has no member named ‘reg’ COMPILE_ERROR_IF_TYPES_NOT_COMPATIBLE(OBJ_REGISTER(obj), (id_ctx).reg) src/mbc-plugin.c: In function ‘mbc_mail_user_created’: /usr/include/dovecot/src/lib/module-context.h:46:67: error: ‘struct mbc_user_module’ has no member named ‘reg’ COMPILE_ERROR_IF_TYPES_NOT_COMPATIBLE(OBJ_REGISTER(obj), (id_ctx).reg) Obviously the module context nowadays expects another attribute/struct named "reg". However, I cannot find any information about this within the documentation and plugin mentioned above. The only clue I have got yet is the definition in module-context.h: union STRUCT_NAME_module_context { struct STRUCT_NAME_module_register *reg; // it's allowed to have some structure here so it won't waste space. // for example: struct STRUCT_NAME_vfuncs super; }; However, I still cannot make any sense of it (yet). Could you please help me in filling the gap and understanding, what has to be changed? Thanks a lot in advance for an awesome piece of software and any input on this topic, Lukas

FTS lucene indexer-worker segfaulting
by Florian Pritz 24 Jul '14

24 Jul '14

Hi, I've just set up fts-lucene and when I run searches on my inbox or when I run the indexer (`doveadm index INBOX`) I get the following segfault. I've run it multiple times and noticed that the data value is different each time so I guess it doesn't always crash at the same point. I'm running dovecot 2.2.13-1 with clucene 2.3.3.4-8 on Arch Linux.

Dovecot GMail API
by Timo Sirainen 23 Jul '14

23 Jul '14

Hi all, I'm still (mostly) on vacation this week and afterwards lots of different things to do .. But hopefully I'll still get around to answering all the pending mails in this list and applying some of the patches people have sent and get the next v2.2.14 release out. Anyway, people have kept asking about GMail API and Inbox App and how that affects Dovecot. For a while now I've been planning on implementing some kind of a HTTP API for mail access, so might as well use GMail's: http://www.dovecot.fi/dovecot-launches-a-gmail-api-compatible-rest-api-to-e…

SSL certificate problem (SSL alert number 42)
by Boyandin Konstantin 23 Jul '14

23 Jul '14

Hello, After client (Thunderbird, now version 31.0) updated today, it stopped connecting to Dovecot IMAP4S. The infamous "SSL alert number 42" is reported. Mail server uses local (created for intranet) CA certificate as root. I would appreciate pieces of advice on how to handle that without enabling plaintext authentication over insecure channels. Other intranet services work with this local CA quite fine. Thank you in advance.

[patch] enable ECDH auto functions based on feature defines, not on version number
by Hanno Böck 22 Jul '14

22 Jul '14

Hello, I recently tried to build my system with libressl instead of openssl. In dovecot one issue that popped up was that libressl doesn't have the ECDH auto functions from openssl 1.0.2 beta versions. However as the #ifdef's in dovecot's code check for the openssl version and libressl's version numbers are higher the compilation fails there. Attached is a patch that will change that checks. Instead of checking for the version number it checks for the availability of the feature itself (by checking for the define of SSL_CTRL_SET_ECDH_AUTO). This should make this check more robust and work independently of the version number of the used openssl instance. cu, -- Hanno Böck http://hboeck.de/ mail/jabber: hanno(a)hboeck.de GPG: BBB51E42

BUG: Authentication client sent unknown handshake command
by Lukas Haase 22 Jul '14

Hi, Some time ago my dovecot started to become BUGgy: Evertime I restart the system, dovecot is started but I cannot login. I see the following information in the logs: Jul 4 04:04:36 mail dovecot: auth: passwd-file(user,127.11.91.218,<nfkQjFT9vwCADFra>): no passwd file: /etc/dovecot/imap.passwd Jul 4 04:04:36 mail dovecot: auth: Error: BUG: Authentication client sent unknown handshake command: REQUEST?1183186945?20438?1?a8c7241e7b0778f9f0125da760cd16fa Jul 4 04:04:36 mail dovecot: imap: Error: Authentication server didn't send valid SPID as expected: MECH#011PLAIN#011plaintext Jul 4 04:04:36 mail dovecot: imap: Error: Disconnected from auth server, aborting (client-pid=20438 client-id=1) Jul 4 04:04:36 mail dovecot: imap-login: Internal login failure (pid=20438 id=1) (internal failure, 1 succesful auths): user=<user>, method=PLAIN, rip=127.11.91.218, lip=73.82.101.172, mpid=20439, TLS, session=<nfkQjFT9vwCADFra> It does not help to restart the client. But when I then restart the server service dovecot restart it works again.

subfolders in public mailboxes
by Burak Arslan 21 Jul '14

21 Jul '14

Hello, I added this to the configuration: namespace { type = public separator = . prefix = public. location = maildir:/var/mail/public subscriptions = no list = yes } and I can list maildirs inside these folders correctly. however, I can't see any subfolders. The issue seems to be that /var/mail/public dir itself is interpreted as a maildir directory. However, what I'd like to do is to have a bunch of directories inside /var/mail/public and treat them as separate maildirs. (I'd like to use this to make a few existing mailboxes public) is this possible? Best regards, Burak

Dovecot Replication: First Run
by Asai 19 Jul '14

19 Jul '14

Greetings, I'm working on building a redundant Dovecot server which will be replicated with my original. I would like to know if there's any potential problems I could run into in running this for the first time. For example, during an initial sync is it possible for the new server to sync improperly with the original and delete all of the emails on the original? Are there any gotchas that I should be aware of when doing a first run? -- --Asai

Difference btw. Dovecot Director and Dovecot Proxy
by Nathan Schultheiss 19 Jul '14

19 Jul '14

Hello, For a few days I try to understand what program (Dovecot Director or Dovecot Proxy) I should use for my email architecture. We are a hospital, and for security reasons, we must host ourselves our emails, and we must leave Google Apps... I wish to make a Dovecot backend for each department of the hospital. Each backend Dovecot has a local storage. Server 01: cardiology Server 02: emergency ... Server 05: administration Dovecot looks in the database which server to use to store email (lmtp) and transfer the mail for storage. I do not understand if I have to work with Dovecot Director or Proxy if I would that LMTP or IMAP request are forwarded to the right backend. Each have self storage and have not access to the other backend storage (no nfs, no network storage, ...). Users indicate imap.hospital.local, this point to Dovecot Director or Proxy and Dovecot check the login/password and forward the user to the right backend. In my database I put user@hospital = storage host 172.16.2.10 = folder /home/vmail/user/ (Maildir) I've read that the Director can refer the user to the same backend when there is a activ session (POP, IMAP, LMTP) But can we tell him to always refer the user to the same backend (IMAP and LMTP) ? I've found this picture schema who user have Dovecot Proxy => Dovecot Director => Dovecot Backend And I'm confused why they have proxy + director ?!? Can anyone tell me if I need to focus on Dovecot Director or Dovecot Proxy to create the architecture of this hospital ? My question is probably stupid for Dovecot sysadmin, but I'm lost in the WIKI :) Thanks in advance, Nathan

Postfix user@domain splitting
by Ricardo Branco 18 Jul '14

18 Jul '14

I have been trying looking though all the wiki documents to setup LMTP. It now seems to all be connected except that it keeps saying that the user is not recognised when postfix sends to LMTP, it sends the full recipent email address but seems that on the dovecot side it is unable to work with this. I have checked the userdb and made sure its using %n but alas it still does not work. Currently ive had to revert to using LDA as it works fine with that but i still dont know how as the postfix config variable $RECIPIENT is the full email address and does not seem to matter to LDA.

Dovecot/K9/Thunderbird IMAP interaction issues: replicated messages, constant reloading (TB) & missing new messages (K-9)
by David Gessel 18 Jul '14

18 Jul '14

Version Info: FreeBSD 9.2-RELEASE #0 r266046 AMD64, Dovecot 2.2.13, dovecot-pigeonhole-0.4.3, amavisd-new-2.8.0_2,1, clamav-0.98.4, postfix29-2.9.9_1,1, postfixadmin-2.3.6, spamassassin-3.4.0_12 (zpool data and output of dovecot -n at bottom of post) I suspect these are related problems and further that they are related to some trivial newb error I've made in my configuration, but searching descriptions of the symptoms has not yet guided me to a solution. I recently migrated from Courier to Dovecot on new hardware and imap synced a 16GB mailstore (du -hs) divided up into annual directories with about 15,000 messages each. I mention the size because it seems an errant Remove Duplicate Messages (Alternate) 0.3.9 acting on what seem to be false duplicates in Thunderbird reduced the inbox size from 7500-ish messages to 1300 (DOH!) and may have solved my K-9 problem described below. My old Courier server still has the vast majority of these messages and I will resync someday and then try to file them away more expediently than my previously somewhat lazy management style to keep the inbox small. * In thunderbird, I get constant downloading of messages. Every time I switch to the inbox from another folder, the messages start redownloading. This sometimes, but not always, seems to create duplicate messages, but I'm now fairly sure they are only created in the client and not on the server. Searching through various forums, it appears this has been a problem for Thunderbird for some time, but it wasn't for me on Courier. As posts about similar errors seem to have petered out over the last year without any clear guidance on how to fix it that I could find, I expect there's a simple fix I just haven't found yet, either in TB configuration or in Dovecot. Any hints? I tried Thunderfix to remove the .msf files and will be redownloading my mail over the thin pipe out to Iraq for the next 6 months (DOH!). One artifact is that when I restart thunderbird, my inbox is reported as having about 130 messages in it, then thunderbird starts redownloading headers and eventually gets back up to the 1297 currently listed both in the TB pane and by ls | wc -l in /cur. Is it possible there is a time out that needs to be extended? In TB, I've set (among other less apparently relevant options) mailnews.tcptimeout;1000 mail.db.idle_limit;30000000 * Also, with Thunderbird, I get duplication of messages in the client. I suspect this is related to the previous redownload error, but there is some indication in some posts that it is potentially related to a dirty flag. I've had this problem before with Thunderbird and Courier, but it went away after a TB update. It seems to have reappeared with Dovecot. The TB client hasn't been updated during the transition, so some interaction issue seems more likely than a pure TB bug. Likely TB's fault as this is a well known, but poorly diagnosed TB issue (deleting duplicates regularly seems to be the solution, but my inbox would double in size every few hours on the LAN. Now that I'm remote over a 2mbps link, it has slowed way down: bonus!). * "Expunged message reappeared, giving a new UID" errors appear a lot. This might well be related to the last error. This seems to happen with TB client connections, but I'm not sure what action triggers it. I am not replicating. I tried renaming 10-director.conf to 10-director.conf.disabled and got no complaints from Dovecot (as I'm not using replication, it shouldn't) but that indicates that this Expunged message reappeared error is probably of a different source than, for example, Simon Fraser's debug effort. * K9 was only showing a subset of my messages and generally not the new ones. They'd appear in the alert properly, but weren't visible in the client and sometimes they'd be visible and then disappear later. I imagined there could a correlation between TB checking mail and perhaps moving messages from /new to /cur and K9 losing track, but the potentially tragic "duplicate" removal may have reduced my inbox to a size that k9 can handle as K9 inbox display seems normal now as far as I can tell. When I resync (assuming I can), I sort of dread this problem reappearing. K9 worked as expected against Courier with the same inbox. These apparently difficult to diagnose problems are occasionally suggested as related to namespace configuration issues and thunderbird is reported to have issues with some separator options. I vaguely suspect this, but I'm pretty sure my namespace config is default and should be well tested. I haven't, for example, explicitly stated the default "/" but left it commented out. I increased the connection limit count per user*IP to 20 as TB seems to be parallel downloading a lot of folders. This has neither improved nor degraded performance in any way I can see and is probably irrelevant. Any hints greatly appreciated.

Sieve: adding Date: header when missing
by Daniele Nicolodi 17 Jul '14

17 Jul '14

Hello, there is a way with a sieve rule to add a Date: header when it is missing? Adding one with the time of reception of the message or using the date from the the first Received: header would be good options. Unfortunately I'm receiving some useful automated messages that lack a Date header and this screws up the sorting in my imap clients. I have a script to fix those acting on the Maildir storage, but I would prefer to have the thing solved more radically. Thanks. Cheers, Daniele

If local Dovecot stops working, check lo
by Steve Litt 17 Jul '14

17 Jul '14

Hi all, You probably know this already, but just in case... Let's say you have your email client getting mail from a Dovecot server on the same computer (which is a really good way of doing things, by the way). Then one day your email client starts saying "connection refused" after a suitably long timeout. So then, to find out where things are getting stuck, you do the following command: openssl s_client -connect 127.0.0.1:993 -quiet And you don't even get an OK back. This means it's not your username or password, because you never even got that far. Before spending a lot of time doing diagnostic tests and narrowing it to the root cause, try this as root: ifdown lo ifup lo A malfunctioning lo will cause Dovecot not to connect to clients. My experience with Debian Wheezy is that lo "goes down" a lot, so this is one of the first things I do when odd stuff happens.

Resource Temporarily Unavailable on replicator-doveadm
by Cassidy Larson 16 Jul '14

16 Jul '14

We're running 2.2.13 on two servers with replication. Still trying to get my replication tweaked correctly and I’m noticing a bunch of these errors for the same users over and over again: dsync-server(user(a)host.com): Error: write(/var/run/dovecot/replicator-doveadm) failed: Resource temporarily unavailable The 5-7 that I see all have quite a number of individual mailboxes (20+), I’m wondering if that has something to do with it? Also, my replicator status for full resync requests has been hovering around 2300-2400 the last few days: # doveadm replicator status Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 2410 Waiting 'failed' requests 1 Total number of known users 9836 In checking the replication status for some of the “Resource temporarily unavailable” list from above, if I run it multiple times it outputs different results for the fast and full sync time: # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:20:21 49:43:34 - # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:10:55 00:10:55 - # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:10:56 00:10:56 - # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:10:57 00:10:57 - # doveadm replicator status user(a)host.com username priority fast sync full sync failed user(a)host.com none 00:20:24 49:43:37 - doveconf output for the replicator service is: service replicator { process_limit = 10 process_min_avail = 2 unix_listener replicator-doveadm { group = mailsys mode = 0666 user = mailsys } unix_listener replicator { group = mailsys mode = 0666 user = mailsys } } Anybody have any clues or suggestions? I’d be much appreciative. Thanks, Cassidy

Tried mailing the maintainer, but didn't get a response -- anyone know what's happened to the ATrpms repo? Not only is http://atrpms.net/name/dovecot/ empty, but: http://packages.atrpms.net/dist/el6/ seems to return a 404. Some of the mirrors still have the packages, but does anyone know if they're going to continue to build 2.2.x packages? w

Hi, Could anyone share any numbers about real life solr database size/cpu/memory usage for certain amounts of messages ? We have now over 5TB of maildirs (about 5 000-6 000 concurrent imap clients) and I'm trying to guess how much hardware might be needed. -- Michal

Dovecot2 Antispam MAILTRAIN backend with SpamAssassin
by Mohammad S. Babaei 15 Jul '14

15 Jul '14

Hi there, I've already asked this question on FreeBSD forums without getting any response. So, I thought it's a good idea to ask it again here. I've setup Dovecote2 (2.2.13) + Postfix + SpamAssassin on my FreeBSD 10 VPS and it works flawlessly. Though, I couldn't setup the Dovecot Antispam plugin to train SpamAssassin when I move mails to the Junk folder. I installed the plugin from FreeBSD ports and followed the official documentation [1] and the man page [2] without any success.

Permissions with mailman
by Niklas Lemcke - 林樂寬 15 Jul '14

15 Jul '14

Hi, I'm running a Mailserver, and recently also a Mailinglist. I'm sporting # dovecot --version 2.1.7 on a debian stable machine with postfix & mailman. Everything works fine, except that no archive is being created (here an excerpt from my log): Jul 2 15:29:39 blade01 postfix/qmgr[5217]: B30BCE1F52: from=<list(a)mail.myserver.com>, size=802, nrcpt=1 (queue active) Jul 2 15:29:39 blade01 dovecot: lda(list): Error: user list: Initialization failed: Initializing mail storage from mail_location setting failed: mkdir(/var/mail/vmail//list/mail) failed: Permission denied (euid=38(list) egid=38(list) missing +w perm: /var/mail/vmail/, we're not in group 5000(vmail), dir owned by 5000:5000 mode=0775) Jul 2 15:29:39 blade01 dovecot: lda(list): Fatal: Invalid user settings.

Now: $ groups list list : list vmail and the permissions are 775, but it's still complaining about "missing +w perm". What is it referring to with "we're not in group 5000"? Thanks for any help! -- Niklas - 林樂寬

Changed IMAP MOVE behavior in Dovecot 2.2.x
by Iavor Stoev 15 Jul '14

15 Jul '14

Hello, After the migration to Dovecot 2.2.13 from Dovecot 2.1.17, I noticed a changed behavior when I move a message from one folder to another. I use Thunderbird with: Account Settings -> Server Settings -> When I delete a message: Just mark it as deleted. I use Thunderbird 24.6.0 with IMAP. With Dovecot 2.1.x when I move a message, the message appears in the new folder and is marked for deletion in the original folder (which gives me an easy option to undo the action if I made a mistake until I choose to Compact/Purge the folder). With Dovecot 2.2.x when I move the a message it is marked for deletion and is AUTO Compacted/Purged immediately. Is there a way to achieve the 2.1.x behavior with Dovecot 2.2.x? Thank you Iavor

Integrity check of mailboxes before dsync
by Murray Trainer 15 Jul '14

15 Jul '14

Hi All, I am migrating a large number of Dovecot mailboxes - some of them are quite old. I hit an issue yesterday with a corrupt file (index?) that was preventing the mailbox from being synced properly As soon as I removed the file the dsync worked. Is there a way to check the integrity of each mailbox / indexes before I dsync it? Thanks Murray

director / main instance
by Will Yardley 15 Jul '14

15 Jul '14

I have directors and backend servers running on the same systems (x3). To be able to run doveadm foo with a minimum of fuss (without having to list socket paths explicitly), should it be the director that's the "default"? If so, is it safe to symlink '/var/run/dovecot' to '/var/run/dovecot-director', or should I just make the director's base path /var/run/dovecot directly? in dovecot-director.conf, I have: service doveadm { inet_listener { port = 8889 } } local 192.168.x.0/24 { doveadm_password = Foo } doveadm_proxy_port = 8888 and in dovecot-main.conf, I have: service doveadm { inet_listener { port = 8888 } } local 192.168.x.0/24 { doveadm_password = Foo } protocol doveadm { auth_socket_path = director-userdb } Is this correct (and is there anything unneeded / redundant there)? # dovecot instance list path name last used running /var/run/dovecot-director director 2014-07-14 20:36:49 yes /var/run/dovecot-main main 2014-07-14 20:36:49 yes # dovecot director status mail server ip vhosts users 192.168.x.xx 100 2 192.168.x.xx 100 0 192.168.x.xx 100 0

Transition from one server to another.
by Anders Wegge Keller 15 Jul '14

15 Jul '14

A frind of mine and I are running a dedicated server, that among other things host mail for ourselves and friends and families. All in all about 15 different domains with 35-40 users. The machine in question is old, so we are doing a slow transition from the old server to the new one. So far, we've managed to move web hosts seamlessly. Due to the technical capabilities at some of the user base, it would be nice to get to a setup, where we can move individual users imaps from the old server to the new one, as we get the time to visit them. I have an idea how such a transition could go: 1. Upgrade the old dovecot 1.2.15 to 2.1.whateveritis from debian squeeze backports. 2. Set dsync up to replicate mails from the old server to the new server. I know that 2.2 is recommended, but with a limited amount of user, I'm willing to take a performance hit. 3. Migrate my parents &c to use the new server. 4. When all users have been moved on to using the new server, upgrade MX records for the domain to point at the new server. 5. When all MX records are updated, decalre success. Is this feasible, and what would the risks be. For instance, during step 4, mails are bound to arrive at bothe the old and new server for some time. Will this cause problems? Is there a simpler solution to the problem? -- /Wegge Leder efter redundant peering af dk.*,linux.debian.*

protocol specific AuthDatabase Queries
by claus 14 Jul '14

14 Jul '14

Hi, i have to configure different sql-queries for protocol lmtp, another for protocol smtp and one query for other protocols. I have configured in "/etc/dovecot/conf.d/auth-sql.conf.ext" one entry for all protocols and 2 protocol specific entries: protocol lmtp { passdb { driver = sql args = /etc/dovecot/dovecot-lmtp-sql.conf.ext } } protocol smtp { passdb { driver = sql args = /etc/dovecot/dovecot-smtp-sql.conf.ext } } passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } is this correct or do i have to configure all possible protocols seperately? First i had a working configuration for all protocols except for lmtp (but now i need additionally a special query for smtp): protocol !lmtp { .. } protocol lmtp { .. } Can you tell me whats the prefered configuration? Thanks Claus

doveadm dump ignores .pvt
by Thomas Herrmann 14 Jul '14

14 Jul '14

While debugging a different problem, I used "doveadm dump" to show information about a maildir folder; it happily reported values from dovecot.index and dovecot.index.log (confirmed by strace): [...] messages count ........... = 978 seen messages count ...... = 967 [...] However, mail clients reported different values, I guess because the Seen flags were actually stored in the dovecot.index.pvt.log files. Is this a known problem or a result of my (maybe unsupported?) setup? My public maildir folder contains only links to mailboxes of the private maildir of the mail admin, i.e.: /home/vmail/public/.Info -> ../adwin.de/mail-admin/Maildir/.Info namespace { list = children location = maildir:/home/vmail/public:INDEXPVT=/home/vmail/adwin.de/%n/public prefix = ADwin/ separator = / subscriptions = no type = public } My setups leads to .pvt-files in the public namespace, could this be a problem? http://wiki2.dovecot.org/SharedMailboxes/Symlinks explicitly states that symlinking _should_ work. Using version 2.2.13 (debian packages). Regards, Thomas

Flags in public folders disappear when more than 25 flags are used
by Thomas Herrmann 14 Jul '14

14 Jul '14

Hello, I have been using flags in public folders for quite a while with no problems. Once the flags were added to all clients (Thunderbird), they were visible and synchronized properly. Now I have added some new flags, and in the dovecot-keywords files I see that I am now using more than 25 flags (in which case they are not stored using an additional letter in the filename). Now I see that newly added flags are only visible in the client for a short time and then suddenly disappear. How can I debug this, or what may be a reason for this?

High user number tune
by Edwardo Garcia 13 Jul '14

13 Jul '14

Halo, This might seem like another indirect thread. I Monday started new job, first task must replace courier. The job use POP3. and IMAP only for webmail, but must server support 4K POP3 at one times. I see from similar thread current settings not adequate , we will use TLS and if wiki read right Iprotocol So am close in think that need ? service pop3-login { process_limit = 4096 } service pop3 { process_limit = 4096 } service imap-login { process_limit = 2048 } service imap { process_limit = 2048 } then we have service managesieve { process_limit = 1024 } is that all we need change? I see in other thread someone says service anvil but I can not find out about it, does need change as well ? Why is it so complicated to change to let more user on, most other change one setting, dovecot want dozen :(

Pigeonhole sieve misfile
by Patrick Domack 13 Jul '14

13 Jul '14

I'm having an issue with sieve putting some emails into the spam folder, that should not be matching the spam rule. I tried looking but can't seem to find a debug option. Is there any way I can get a log of what the sieve rule path that matches so I can locate the misfiring rule? or maybe something else that is going on. I already checked the dovecot sieve log file, and there is nothing in there.

macros
by Arkadiusz Miśkiewicz 13 Jul '14

13 Jul '14

Does dovecot support any form of macros? I would like to share configuration file between several servers. Configs are different only in tiny aspects. Somethine like: dovecot-server.conf (different on each server): %define ID 55 %define SOMETHING SELECT FROM * WHERE something %define MECHANISMS digest-md5 dovecot-main.conf (common, shared config) !include dovecot-server.conf user_query = ${SOMETHING} AND id=${ID} auth_mechanisms = plain login ${MECHANISMS} etc -- Arkadiusz Miśkiewicz, arekm / maven.pl

Replication on dovecot 2.0
by Tom Barber(Alabs) 11 Jul '14

11 Jul '14

Hi Guys I'm running an Ubuntu 12.04 LTS server and not being particually inclined to upgrade I'm wondering what options I have for replication as it appears to be running dovecot 2.0.19. I saw the wiki page about replication and whilst it says you should use 2.2+ it doesn't say what the minimum requirements are, so I tried doing what it says but I get: Fatal: Plugin 'replication' not found from directory /usr/lib/dovecot/modules Any ideas or tips. Thanks Tom

1.2.4 disk full errors
by Iain Hallam 11 Jul '14

11 Jul '14

Hi. A user on a rather old mail system we have filled their disk space, and Dovecot has started to give lots of errors in the logs about "Expunged message reappeared" and "Duplicate file entry". The user can only see a few new messages, not the 33,551 in their inbox. In the TODO file in the current source code[1], Timo notes that (line 147): maildir: out-of-disk-space failures apparently cause all kinds of problems, e.g. "Expunged message reappeared", "Duplicate file entry"? [1] http://hg.dovecot.org/dovecot-2.2/file/c55c660d6e9d/TODO Does anyone know what's happening with Dovecot here and how to recover so that this user can see mail again? Unforuntately we're on a very old version, 1.2.4. Though there is a plan for migrating to a newer platform, I need to get this user accessing email again rather more urgently. Thanks, Iain Hallam.

dovecot lda invalid user settings
