If local Dovecot stops working, check lo
by Steve Litt 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

Hi All, I have noticed that dovecot / exim on Cpanels appear to support sending emails via exim after authenticating to Dovecot - see message below 550-Please turn on SMTP Authentication in your mail client, or login to the 550-IMAP/POP3 server before sending your message We are migrating users mail off cpanels into split mta and dovecot servers and are having problems with some users being abble to send emails afterwards. Does anyone understand how the CPanel config works? Thanks Murray

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.

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

All, Just move our mail servers over to a new mail server running postfix 2.11.1 and dovecot 2.2.13 and getting the subject line errors in my /var/adm/files.

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.*

Have you tried: 10-master.conf service imap { drop_priv_before_exec=yes } as suggested by the error?

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? Regards Thomas Herrmann root@mailsrv2:~# dovecot --version 2.1.7 root@mailsrv2:~# dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.5 xfs disable_plaintext_auth = no log_timestamp = "%Y-%m-%d %H:%M:%S " mail_fsync = never mail_location = maildir:/home/vmail/adwin.de/%n/Maildir mail_privileged_group = mail 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 ihave imapflags namespace { inbox = yes location = prefix = separator = / subscriptions = yes type = private } namespace { list = children location = maildir:/home/vmail/public:INDEX=/home/vmail/adwin.de/%n/public prefix = ADwin/ separator = / subscriptions = no type = public } passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { acl = vfile sieve = /home/vmail/adwin.de/%n/dovecot.sieve sieve_dir = /home/vmail/adwin.de/%n/sieve sieve_extensions = +imapflags +imap4flags } protocols = imap lmtp sieve service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { mode = 0600 user = vmail } user = root } service imap-login { inet_listener imap { address = *,:: port = 56143 } inet_listener imaps { address = *,:: port = 56993 ssl = yes } service_count = 0 } service imap { vsz_limit = 512 M } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } service managesieve-login { executable = /usr/lib/dovecot/managesieve-login service_count = 0 } service managesieve { executable = /usr/lib/dovecot/managesieve } ssl_ca = </etc/dovecot/ca-bundle.crt ssl_cert = </etc/dovecot/XXXXXXXXXXXXXX.crt ssl_key = </etc/dovecot/XXXXXXXXXXXXXXX.key userdb { driver = passwd } userdb { args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes driver = static } protocol imap { mail_max_userip_connections = 100 mail_plugins = acl imap_acl } protocol imaps { mail_max_userip_connections = 100 mail_plugins = acl imap_acl } protocol lda { auth_socket_path = /var/run/dovecot/auth-master log_path = /home/vmail/dovecot-deliver.log mail_fsync = optimized mail_plugins = sieve acl postmaster_address = XXXXXXXX(a)XXXXX.de } protocol lmtp { mail_plugins = sieve acl }

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.

Hi All, I have the Dovecot quota value coming from LDAP using the line below but my values are stored in MB, not bytes. What can I put in the line to set quotas in MB? user_attrs = homeDirectory=home,mailUID=uid,mailGID=gid,mailQuota=quota_rule=*:bytes=%$ Thanks Murray

Trigger for using an sqlite dictionary for quota
by David Anderson 10 Jul '14

10 Jul '14

Hi, I'm using Dovecot 2.0.9, and was trying to set up a dictionary process to use an sqlite database for quota management. The wiki page has examples for MySQL and PostgreSQL: http://wiki2.dovecot.org/Quota/Dict For sqlite, a trigger needs to be created to get it to work. But I was not sufficiently skilled in sqlite to adapt the PostgreSQL trigger (given on the above URL) for use. Nor did Googling find any example of anyone else who had done it. Does anyone here have an example, or the ability? (Through Googling I found an example trigger for using sqlite with expiries - but I was looking at quotas).

HIGHESTMODSEQ tracking
by Kostya Vasilyev 10 Jul '14

10 Jul '14

Hello, I'd like to follow up on someone else's old thread: http://dovecot.org/list/dovecot/2012-April/082624.html I understand that Dovecot (that 2012 discussion was about version 2.0.18) can return "HIGHESTMODSEQ 1" upon SELECT if persistent modseq tracking was never enabled for a mailbox. I'd like to get a clarification on how to enable proper persistent modseq tracking. Per RFC 4551, "A client supporting CONDSTORE.... indicates its willingness to receive mod-sequence updates... by issuing:" SELECT mailbox (CONDSTORE) STATUS (... HIGHESTMODSEQ ...) ... others ... It seems that Dovecot 2.1.7 (Debian 7.5) enables persistent modseq tracking after one of the above two commands (and maybe others). So far so good. So my questions are: 1 - Is this (enabling persistent modseq) also the case for all Dovecot versions prior to 2.1.7 that advertise CONDSTORE? There must be people running older versions out there, older than 2.1.7. If not, how can I branch my logic to not use HIGHESTMODSEQ, given that Dovecot doesn't appear to return any version info via its greeting or via the ID command? 2 - Is persistent modseq tracking (assuming it's been enabled) available for all types of backend mailbox formats that Dovecot might be using? To be more specific, can it ever be the case that Dovecot appears to enable modseq tracking, returning nice looking HIGHESTMODSEQ values from SELECT / STATUS, but the actual values get reset or not get updated because they're not properly persistent? I'm excluding changes to UIDVALIDITY here, obviously when that changes, the entire mailbox state must be assumed to have changed completely. 3 - I guess the change to return NOMOSEQ instead of "1" for mailboxes with modseq tracking disabled, as mentioned in that discussion from 2012, never happened? At least on the 2.1 branch? Thanks, -- K

Multiple email clients not in sync
by Marc Perkel 09 Jul '14

09 Jul '14

Hello everyone, I'm not sure if this is an issue with dovecot or my various email clients, or my settings. I'm running 2.2.13 and I have Thunderbird on my desktop and K@mail on my android phone. In theory if I delete email on one it should delete it on the other. It does delete it on the server - but the other client isn't always "aware" of it. Same thing sometimes with read messages. I read on one device but the other didn't know it's read unless I shut down and restart the app. Not knowing the details of how this all works I'm assuming there is some form of notification that goes on in the background so as to let other clients know what other clients do so they can sync up. And that where my setup isn't working consistently. Maybe my expectations are just too high? Maybe I don't have things set up correctly? What am I missing? Thanks in advance.

Problem with virtual mailbox when using K9 mail (android)
by Henrik Kjölhede 08 Jul '14

08 Jul '14

Hi! I've managed to setup a virtual mailbox that shows all unread or flagged mail from a selection of IMAP folders. This works great with Roundcube, which I use as webmail client. However, using K9 mail on my android phone, a mail that is opened seems to be immediately marked as read, and any flagging I do doesn't take. Presumably this is because it can't be reached any longer in the virtual folder. I tried adding the recent flag to the virtual search line, but that doesn't make any difference. I haven't been able to locate any information about anyone else experiencing this problem, so I was hoping that someone here could help. I realise that this is not exactly a "dovecot problem", but perhaps someone here has found a solution that they are willing to share. The search line in dovecot-virtual is currently "OR RECENT (OR UNSEEN FLAGGED). Regards

Limit confusion
by Micah Anderson 08 Jul '14

08 Jul '14

Hi, On one of my dovecot servers, i've got a limit problem... and I'm a little confused about which knobs I should adjust to solve it. I've been getting both of these: Error: net_connect_unix(imap) failed: Resource temporarily unavailable - http://wiki2.dovecot.org/SocketUnavailableess This one caused me to go read that wiki page, but none of those seem to apply to me: . i'm running 2.2.9 . i dont have service imap { client_limit }, although I do have service auth ( client_limit = 1024 } . my dovecot/auth process shows: dovecot/auth [91 wait, 0 passdb, 0 userdb] . it doesn't appear the master process is using very much cpu (in fact the system is mostly low load in general) . I have service_count = 0 set for imap-login for the 'high performance mode' dovecot: master: Warning: service(imap): process_limit (2560) reached, client connections are being dropped The second is because I have process_limit of 2560 for the imap service...

Dovecot ignores existing mailboxes and creates its own
by Martin Vegter 08 Jul '14

08 Jul '14

Hello, I have Postfix with Maildir format. User's emails are being delivered into $HOME/mail/inbox Apart from ~/mail/inbox, there are the usual folders: $HOME/mail/archive $HOME/mail/drafts $HOME/mail/inbox $HOME/mail/trash Now I have installed dovecot, and set mail_location = maildir:~/mail:LAYOUT=fs additionally, I have defined mailboxes as follows: namespace inbox { mailbox drafts { special_use = \Drafts } mailbox sent { special_use = \Sent } mailbox trash { special_use = \Trash } } The problem I am having is following: 1) dovecot ignores the folders (drafts, sent, trash) and creates its own folders begining with capiotal letter: Drafts Sent Trash 2) dovecot ignores ~/mail/inbox and instead creates ~/mail/cur ~/mail/new ~/mail/tmp can somebody please advise how to tell dovecot, to use my existing folder structure, ie: ~/mail/inbox/{cur,new,tmp} ~/mail/drafts/{cur,new,tmp} ~/mail/sent/{cur,new,tmp} ~/mail/trash/{cur,new,tmp} any advice would be much appreciated thanks, Martin

Redis sentinel support in dict
by Lazy 08 Jul '14

08 Jul '14

Redis sentinel ( http://redis.io/topics/sentinel ) is a service that monitors and manages redis master slave replication. Using sentinel you can easily create a redis ha cluster. You can connect to a sentiniel and subscribe to certain events then in case of an failover update the redis address to new master etc. I think this is better suited to be used with dict proxy. Do You think it can be implemented without changes to dovecot core ? -- Michal Grzedzicki

dovecot 2.2.13 core dump (signal 11)

Multiple Instances with Director
by Cassidy Larson 08 Jul '14

08 Jul '14

I have four front end servers with two backend servers. Each front end server has three instances for different mail hosts (individual SSL certs, etc). I'm looking at adding a fourth instance on each front end server for the director process. Currently we just return the backend server ip via SQL and use the old master username/password to proxy the inbound POP/IMAP sessions to the correct backend server. The plan is for each instance to have connect to the same list of director_servers (one from each front end server). What's the trick to separate a director instance into its own setup and having multiple instances/servers connect to that director? Currently I have on my proxy instance: director_servers = 10.128.1.42:9090 (this is the inet_listener from the director instance) service director { unix_listener login/director { mode = 0666 } fifo_listener login/proxy-notify { mode = 0600 user = $default_login_user } unix_listener director-userdb { mode = 0600 } } And I get in logs: director: Fatal: No inet_listeners defined for director service (for standalone keep director_servers empty) Do I need an inet_listener on the front end instance if I want to forward all director queries to the director_servers list? Or is there some other trick to get a proxy front end to talk to a separate director instance(s)? Thanks, Cassidy

question on lmtp logged message
by Leonardo Rodrigues 07 Jul '14

07 Jul '14

Hi, I have dovecot running for IMAP4/POP3 and also local delivery through LMTP. It's working just fine, absolutely no problem on that, setup is fine. Anyway, sometimes LMTP seems to not be able to deliver some messages and keep them on postfixqueue. And on the next or third try, the message gets delivered successfully. The logged message, however, is not helping me identify what is happening.Example: (error - message was expunged) Jun 25 11:49:39 correio postfix/lmtp[21835]: ADB0A1AC05108: to=<vanilson.parreira(a)domain.com.br>, relay=correio.domain.com.br[private/dovecot-lmtp], conn_use=6, delay=13, delays=0.07/0/0/13, dsn=4.2.0, status=deferred (host correio.domain.com.br[private/dovecot-lmtp] said: 451 4.2.0 <vanilson.parreira(a)domain.com.br> Message was expunged (received-date) (in reply to end of DATA command)) (successfull delivery) Jun 25 12:34:42 correio postfix/lmtp[6411]: ADB0A1AC05108: to=<vanilson.parreira(a)domain.com.br>, relay=correio.domain.com.br[private/dovecot-lmtp], delay=2716, delays=2714/0/0/2.3, dsn=2.0.0, status=sent (250 2.0.0 <vanilson.parreira(a)domain.com.br> U7pOLAHsqlPvMgAAHvf8vg Saved) During these two log entries, absolutely nothing was changed, no configuration, absolutely nothing. Everything is local, i mean, no NFS involved. So, finally, question is: what does the 'message was expunged' message given from LMTP means ??? This is happening quite often but, as i mentionted, sooner or later all messages are getting delivered. It's working despite the delay this is causing.

dbox alternate storage and samba
by Francesco 07 Jul '14

07 Jul '14

Hello everyone, i was just wondering if it's possible to use a samba share as an alternate storage for dbox format. I tried creating a samba share, but when i try to move the email to the alternate storage using doveadm altmove, no errors are printed but no mails are moved. Everything works if the alternate storage is simply another directory on the server hard drive. am i mssing something? thanks in advance.

rmdir() EBUSY warnings on 2.2.12

Hi, I'm getting a lot of syslog spam on FreeBSD 10 from nfs_flush_file_handle_cache_dir where, apparently it tries to rmdir() the mountpoint of my mail storage. > Jul 4 00:04:44 mailhost dovecot: imap(user(a)example.com): Error: nfs_flush_file_handle_cache_dir: rmdir(/var/mail/vhosts/example.com) failed: Device busy We're using ZFS and have /var, /var/mail, /var/mail/vhosts, /var/mail/vhosts/example.com and /var/mail/vhosts/example.com/user as separate ZFS datasets (to enable per-user and per-domain snapshotting). So apart from NFS flushing being unnecessary (ZFS != NFS) I'm not really sure why using rmdir() for another directory than the Maildir specified in mail_location is a good idea.

by wuwei 07 Jul '14

07 Jul '14

hello everybody: I'm using dovecot with pigeonhole sieve Plugin.everything goes well.but when i use vacation module,i found a problem: I write a sieve with a vacation module in, and put it to the sieve location ,used *PUTSCRIPT* comand with *ManageSieve* and *set it ACTIVE*.It's work!I use A email send mail to him and receive an auto-reply.then ,I modify the sieve only change the days num from 7 to 1.Then I use B email send mail to him and receive an auto-reply too. The next day,I send two mails too.But only B receive the auto-reply.I thought that I would receive two mails too. so i think that A email's data in sieve maybe still 7 days.Then I restart the dovecot,but the problem still exsit. Is anyone know how to refresh the data or is their anyother way to solve the problem? thank you! -- View this message in context: http://dovecot.2317879.n4.nabble.com/help-how-to-refresh-pigeonhole-sieve-v… Sent from the Dovecot mailing list archive at Nabble.com.

If like from Nick Edwards suggested a imapproxy is used it will. imapproxy is keeping the connection open. doveadm who will give you a list of all actual logged in users. Without imapproxy you are right: Every page reload will cause a login and a logoff. I get some webmail users by "accident". To get an overview how many users used roudcube within a period check the database table users/last_login. Andreas

Disable user login for a few seconds ?
by Florent B 05 Jul '14

05 Jul '14

Hi all, I need to move e-mail files of my users from one file system to another. I use a MySQL backend on Dovecot 2.1. How can I do to disable temporary an account while moving files ? I have an "active" bit in my DB, but if I set it to 0, my MX servers are bouncing mails. How can I do to disable temporary an account ? In fact, I need dovecot not to do any change on files... I think I could change account password for a while, and reset it after migration, but it will disturb connected users. Maybe I could chmod 0 files on my old file system during migration ? How Dovecot will act ? Thank you :) Flo

Shared Mailbox + LDAP Easy with this script
by Allan Cassaro 05 Jul '14

05 Jul '14

Hello guys, After some hours fighting with shared mailbox, I finally understand how it works - and, realy, I can't believe how easy it is! So, to help others like me and to improve the shared mailbox with Dovecot this script does all the "hard work". I don't know if this group permit attachments, so, let's the link: https://sites.google.com/site/allancassaro/mkshared.tar.gz Enjoy! ===== From README file ===== This is a simple code to help with Dovecot Public Shared Mailbox function. Just configure a public shared mailbox with ACLs, change the configuration file and run this program. How it works: 1) The program connect to the LDAP server and fetch groups from it (with ldap filter) 2) With groups, it fetches the members and owners (or any attribute you want); 3) It will walk into the "shared folder" folder base directory and: 3.1) Rename any directory that was renamed in LDAP (based on entryUUID ldap attribute); 3.2) Create diretories and skeletion (new, cur and tmp) of any group that exists in LDAP; 3.3) Optionaly, remove any "orphan" directory (wihtout a ldap entrey); Example: dn: cn=Everyone,ou=Shared_Mailbox, dc=example,dc=com objectClass: labeledURIObject objectClass: top objectClass: groupOfURLs cn: Everyone labeledURI: ldap:///ou=Users,dc=example,dc=com?uid?one?(objectClass=person) member: uid=user2,ou=users,dc=example,dc=com member: uid=user3,ou=users,dc=example,dc=com member: uid=user1,ou=users,dc=example,dc=com member: uid=user.surname,ou=users,dc=example,dc=com owner: uid=user4,ou=Users,dc=example,dc=com This will create a folder tree like this: /path/toshared/.Everyone /path/toshared/.Everyone/new /path/toshared/.Everyone/cur /path/toshared/.Everyone/tmp With permission file (/path/toshared/.Everyone/dovecot-acl): user=user1 lr ... user=user.surname lr user=user4 lrwstipekxa Hope this helps you!

Shared folders not listed by IMAP

[Dovecot] dovecot: disable ssl compression
by Andreas Schulze 04 Jul '14

04 Jul '14

Hello, Our "it-security" department asked me about Qualys warnings like -> SSL/TLS Compression Algorithm Information Leakage Vulnerability As far as I learned it's compression inside ssl. postfix-2.11 knows 'tls_ssl_options = no_compression' ( see http://www.postfix.org/postconf.5.html#tls_ssl_options ) is the something comparable in dovecot too? Looks like most extensions in ssl exist only to be disabled :-/ Thanks Andreas

mixing Maildir and mdbox
by gustavo panizzo <gfa> 04 Jul '14

04 Jul '14

Hello i'm in the process to architect a new email system. i plan to use dovecot 2.2.9 (debian's wheezy). i would like to use maildir for 2 folders on each account (spam and no-spam) and the rest of the folders stored on mdbox. this should be opaque to my users. the reason for this, is i want to be able to train my anti-spam tools, but they read maildir or mbox, they don't read mdbox or dbox. but i want the other folders as mdbox (performance, backups, alternate storage) is there any way?, i prefer if is configurable in advance for all accounts but i could live with something that is done after account is created thanks! -- 1AE0 322E B8F7 4717 BDEA BF1D 44BB 1BA7 9F6C 6333

stripping extension from domain name
by Jerry 03 Jul '14

03 Jul '14

Thu, 3 Jul 2014 06:29:06 -0400 I know that the "%d" parameter is for the domain. Is there any way to use just the domain name sans its extension. EXAMPLE: example.com ==> example Also, I have a lot of logging going on in my dovecot log file. I want to limit it to just the barest amount, such as indicting what mail box mail was delivered to. Authentication errors, etcetera should only be shown if an error occurs. Is this possible? Thanks! -- Jerry

ACL configuration migration from Dovecot 2.1.17 to 2.2.13
by Iavor Stoev 03 Jul '14

03 Jul '14

Hello, I'm preparing migration to the latest Dovecot version 2.2.13 from the previous stable branch 2.1.17 which is deployed on my servers. With version 2.1.17 I use global acl dir to prevent all mail users to delete their INBOX.Junk Mail folder, which is part from our spam protection system. My current config is: cat /etc/dovecot/acls/INBOX.Junk\ Mail owner lrwstiae With version 2.2.13, the global acl dir support is disabled (with the above config, the imap server shows no folders at all) so I must use global acl file. The problem is that the "INBOX.Junk Mail" folder contains space character and I tried to escape it with "",'',/ and enclose the whole name with "" & '' without success. If I change the acl config to INBOX.Mail it works OK. The syntax of my global acl file is: cat /etc/dovecot/acls INBOX.Junk Mail owner lrwstiae The error is: Error: Global ACL file /etc/dovecot/acls line 1: Unknown ID 'Mail' Please advise Iavor Stoev Project Manager // Head of System & Network Administration Department

Bug/feature: mail fs pollution on IMAP select namespace/{non-existent}
by Peter Benko 03 Jul '14

03 Jul '14

Hi all, I have noticed a strange behavior with dovecot (tested with 2.2.13). I use shared folders to share mailboxes between users. I have a namespace called "Accounts" that hosts the shared folder for the users (prefix Accounts/%%n/). However, When I issue an IMAP select command on a random non-existent mailbox name under "Accounts", dovecot auto-creates it and pollutes my mail root directory: Python test code snippet: imapConn=imaplib.IMAP4_SSL(serverIP, serverPort) imapConn.login(serverLogin, serverPass) print imapConn.select("Accounts/NonExistentMailbox") imapConn.logout() Resulting in this: drwxr-x--- 1 vmail vmail 4096 Jun 12 10:00 _attachments_ >>> drwx------ 1 vmail vmail 4096 Jun 24 14:27 NonExistentMailbox <<< drwxr-x--- 1 vmail vmail 4096 Jun 24 00:54 user1 drwxr-x--- 1 vmail vmail 4096 Jun 24 01:24 user2 ... -rwxr-x--- 1 vmail vmail 72 Jun 24 14:27 shared-mailboxes.db ls -l NonExistentMailbox/ -rw------- 1 vmail vmail 0 Jun 24 14:27 dovecot-acl-list drwx------ 1 vmail vmail 4096 Jun 24 14:27 mailboxes <<< (empty) I attached a debug log and and my sanitized dovecot config. Please help! Is this a bug or a feature? I assume it might even cause more serious problems e.g., if I would select "Accounts/_attachments_" or something similar... I noticed this behavior with the latest Thunderbird client when I tried to subscribe to shared folders and it started to pollute my mail dirs (which signals that Thunderbird might be also buggy as it should not select non-existent folders under "Accounts"). I just reproduced it for simplicity with the above python script.

Dsync replication one-way
by Muriel 03 Jul '14

03 Jul '14

Hi all, I know that I can do a backup using doveadm: doveadm backup -u user ssh backup.server doveadm dsync-server -u user But it's possible to use replicator service to do the same job? Or dsync with replicator can only be used in a two-way environment? Thanks, Muriel

[Dovecot] zlib maildir reindex broken
by Richard Platel 03 Jul '14

03 Jul '14

I posted to the list about this a while ago but never got a response, I have a bit more information now. Dovecot 2.2.12 and other 2.2 versions are broken when using zlib and maildir. If messages are re-indexed, the INTERNALDATE of all messages is set to the time the re-index is done. The problem seems to be in src/plugins/zlib/zlib-plugin.c in the function zlib_mail_cache_open. During a reindex maildir_mail_get_received_date() does an i_stream_stat on the the i_stream_seekable stream created in zlib_mail_cache_open, but this istream does not know about the original maildir message file and always returns the current time for the file's stat times. This is also broken on initial index, but if mail is indexed when it's received (ours isn't) it coincidentally gets the right time.

BUG: segfault in auth when user listed multiple times in LDAP

Hi, I think I found a bug in the auth module. It can be triggered when the userdb is in LDAP and an user is found multiple times in LDAP.

Bug in quota_get_status
by Franz Knipp 03 Jul '14

03 Jul '14

Hi, the configuration option lmtp_rcpt_check_quota = yes didn't work, so I traced down the problem: quota_get_status (quota_storage.c:89) calls quota_test_alloc (quota.c:1352) with size = 0 bytes, which leads always to a FALSE result in quota_is_over (quota.c:1305). I've fixed the function quota_is_over by considering ctx->bytes_over and ctx->count_over. See the included patch. Kind regards, Franz -- Franz Knipp, +43 664 3980169 qnipp GmbH, Hauptstraße 54, 7064 Oslip, Österreich http://qnipp.com http://qnipp.com/qnipp.vcf

Mailboxes are in Maildir format. Any good backup tips? Had success with version control?
by deoren 03 Jul '14

03 Jul '14

I'm still pretty new to running a mail server, but one thing I've come to appreciate over the years is a good backup strategy. Since I have always run my own servers for practice and for personal use I don't have access to Enterprise backup solutions. Because of that I usually just fall back to scripts and tarballs and offload the content on a regular basis. Right now I'm using LVM snapshots + tarballs for daily backups, but I'd like to get better coverage for incremental changes that occur throughout the day. The size of existing content is low, but (small) changes are frequent. I went with Maildir format because based on my reading it is referred to as time tested and corruption resistant. Because individual emails are stored as separate files this also leads me to believe that a version control system (Git, SVN) would allow for easy point in time restores. I'm also going to research the GNU tar utility's support for incremental archives as that sounds promising. Suggestions and warnings are most welcome. Thanks!

How do you configure an iterate_query SQL lookup for the doveadm director? I tried: service director { userdb { ... } } but userdb is not a valid stanza for director. I do not have a default userdb stanza, all my userdb definitions are specified in service imap/lda/lmtp blocks. Thanks. G H

[Dovecot] TLS/SSL for Win8 & Outlook
by Sebastian Goodrick 02 Jul '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello I recently upgraded to dovecot 2.1.7 (as supplied with Debian Weezy).

[Dovecot] lazy_expunge and shared folders
by Florian 02 Jul '14

02 Jul '14

Hi, since migration to Dovecot 2.2 I have troubles with lazy_expunge as soon as a user shares a folder. The user the folder is shared to cannot login anymore, dovecot logs Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/' - When no folder is shared lazy_expunge is working fine, deleted mails are moved to the expunged namespace and can be recovered without any problems. - Sharing folders works as long as I disable lazy_expunge. I have used the config (with minor changes) with dovecot 2.0 for years without any problem. Switching to dovecot 2.2.10 (atrps repository) or 2.2.12 (dovecot enterprise repo) lazy_expunge and acl do not work together anymore. Is it a bug, a known limitation or is something wrong with my config? Any hints are welcome.

Direct groups of users to pairs of backend mailstores?
by Murray Trainer 02 Jul '14

02 Jul '14

Hi All, We are using Dovecot in a Director setup with two director proxies, six backend mailstores, mailbox storage in NFS, and user accounts stored in LDAP. Currently we have five NFS filesystems on EMC VNX storage which are all mounted on each of the six backend mailstores. At the moment all users could be directed to any of the six mailstores. We have a group of users with very large mailboxes we want to put on separate cheaper Backblaze NFS storage. Because this will be less reliable than our VNX storage we want to be able to direct this group of users to a new pair of backend mailstores that only have the Backblaze NFS mounts. This would isolate the rest of the users isolation from problems with the Backblaze NFS servers. I have read the Dovecot documentation which indicates it is possible to direct users always to a single backend server. Can Dovecot direct users to a pair or more of backend mailstores - ie a subset or another set of mailstores. If not it would be a great enhancement which would allow more scalability, flexibility and redundancy. Thanks Murray

Managing users and home dirs
by deano-dovecot＠areyes.com 02 Jul '14

02 Jul '14

For those of you using virtual users, and SQL, how are you managing your users and their home dirs ? That is, what process do you use for adding/deleting users, creating their home dirs etc ? I suppose it's easy enough to do manually, inserting rows in the database, creating dirs, chown/chmod yada yada, but there must be a better way to do it ... If you're doing dovecot replication then it gets even more cumbersome, having to duplicate the effort in two places (and make sure it's correct). I have a nice test setup using Percona XtraDB Clustering in a 3-node cluster which works swimmingly, albeit in VMs only at the moment. A master DB node and two dovecot nodes. Dovecot replication is up and running nicely too, and I almost have all the communications going over ipsec tunnels, so it will be nice and secure. I'm thinking of something like a cronjob with two tasks, the first would periodically scan the home dirs and compare the users to what's in the database. When it finds a new userdir (plus a file labeled PASSWD) the script would add the user to the database, create the Maildir and whatever else, then delete the PASSWD file. DB replication will push that to the other nodes. The second task is scanning the user database and comparing to the home dirs - basically opposite of the first cronjob. When it finds a user in the DB that doesn't have a home dir, it would create it and whatever else is needed. This way, to add a user one would just create a PASSWD file in /var/mail/domain.com/newusername/PASSWD on either of the dovecot replication partner systems. The first cronjob task would discover the newusername dir, create the user in the DB, create the Maildir, chown/chmod etc. and delete the PASSWD file, so it's ready to go on that system. DB replication pushes the user table to the other nodes. The second task on the other dovecot system will discover a new user in the DB that doesn't have a home dir, and do its thing to create it all. So the whole create-a-new-user process becomes something like this on either dovecot system : mkdir -p /var/mail/domain.com/newusername ; echo "changeme" > /var/mail/domain.com/newusername/PASSWD A max of 5 minutes later the user is added to the database, and the home dir/Maildir/etc/etc is created on both dovecot systems.

i need a little advice with dovecot master user

Hello, As a step to migrate to a newer version of dovecot, i've been asked to configure a master user for logging in into mailboxes of a dovecot 1.2. I've followed the instructions from this page: http://wiki1.dovecot.org/Authentication/MasterUsers but appearently something is going wrong. I've turned on the auth verbose and what i get in the log is: 2014-06-30 15:25:03 auth(default): Info: passdb(administrator,127.0.0.1,master): Master user logging in as user(a)domain.tld but the output from a telnet session says: Trying 127.0.0.1...

Login failure with SElinux enforcing + Sqlite user DB
by G H 30 Jun '14

30 Jun '14

I am having a very strange issue with Dovecot + Sqlite + SELinux in enforcing. I am able to log in via IMAPS if SELinux is in permissive, but not able to do so when in enforcing. I do not see any SELinux denials even with dontaudit's enabled. I am running Centos 5 on x86_64 with a customized kernel build and SElinux Strict policy. The log dumps below are in the following order: 1. My syslog output when SElinux is enforcing 2. My mail client's protocol log (using Sylpheed) 3. My syslog output when SElinux is permissive. From the audit log, syscall 2 (from the message "type=SYSCALL ... syscall=2 success=no" appears to be sys_open for x86_64 architectures. syscall 87 is sys_unlink. Why is my mail client getting a SQL error message even though dovecot's auth log reported login success? Is this a sqlite problem instead of a dovecot one? FYI, I am using dovecot-2.2.10 (from ATrpms.net) and sqlite-3.3.6-7 There appears to be several options related to the temporary store on sqlite's documentation, the solution may be to use memory (instead of files) for temporary tables... dovecot: auth-worker(29695): Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_mysql.so dovecot: auth-worker(29695): Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_pgsql.so dovecot: auth-worker(29695): Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so dovecot: auth-worker(29695): Debug: sql(mailadmin,10.0.77.80): query: SELECT password FROM users WHERE username = 'mailadmin' dovecot: auth: Debug: client passdb out: OK 1 user=mailadmin dovecot: auth: Debug: master in: REQUEST 3487432705 29692 1 17d4d0374be5dec51ce20917470caed8 session_pid=29696 request_auth_token dovecot: auth-worker(29695): Debug: sql(mailadmin,10.0.77.80): SELECT username FROM users WHERE username = 'mailadmin' AND view_mail = 't' AND 'imap' = 'imap' dovecot: auth: Debug: master userdb out: USER 3487432705 mailadmin uid=97 gid=12 home=/var/mail/mailadmin auth_token=e0d0ed3080574ab089f1a5302d43110ffa15ec42 dovecot: imap-login: Login: user=<mailadmin>, method=PLAIN, rip=10.0.77.80, lip=10.0.78.223, mpid=29696, TLS, session=<0C+M3A/9OwCsEQFQ> audispd: node=myhost.somewhere type=SYSCALL msg=audit(1404144473.421:46298): arch=c000003e syscall=2 success=no exit=-13 a0=7fff97f77ce0 a1=c2 a2=1a4 a3=0 items=1 ppid=29697 pid=29699 auid=7033 uid=8 gid=12 euid=8 suid=8 fsuid=8 egid=12 sgid=12 fsgid=12 tty=(none) ses=108 comm="sqlite3" exe="/usr/bin/sqlite3" subj=system_u:system_r:dovecot_t:s0 key="access" audispd: node=myhost.somewhere type=CWD msg=audit(1404144473.421:46298): cwd="/var/run/dovecot" audispd: node=myhost.somewhere type=PATH msg=audit(1404144473.421:46298): item=0 name="./sqlite_ZPh8vGq4ia1CCsJ" inode=8192027 dev=fb:02 mode=040755 ouid=0 ogid=97 rdev=00:00 obj=system_u:object_r:dovecot_var_run_t:s0 audispd: node=myhost.somewhere type=EOE msg=audit(1404144473.421:46298): audispd: node=myhost.somewhere type=SYSCALL msg=audit(1404144473.422:46299): arch=c000003e syscall=2 success=no exit=-13 a0=7fff97f77ce0 a1=c2 a2=1a4 a3=0 items=1 ppid=29697 pid=29699 auid=7033 uid=8 gid=12 euid=8 suid=8 fsuid=8 egid=12 sgid=12 fsgid=12 tty=(none) ses=108 comm="sqlite3" exe="/usr/bin/sqlite3" subj=system_u:system_r:dovecot_t:s0 key="access" audispd: node=myhost.somewhere type=CWD msg=audit(1404144473.422:46299): cwd="/var/run/dovecot" audispd: node=myhost.somewhere type=PATH msg=audit(1404144473.422:46299): item=0 name="./sqlite_9i9aIbK0rBuJWFS" inode=8192027 dev=fb:02 mode=040755 ouid=0 ogid=97 rdev=00:00 obj=system_u:object_r:dovecot_var_run_t:s0 ...

Sieve seems to break mailbody during automatic redirection

Hi, I have a strange problem with sieve. After upgrading to 2.2.13 sieve seems to break the mailbody during automatic redirection.

The part of the mail-header looks normal. But as you can see at beginning of the mailbody something inserts the strange character "^M" after each newline. According to Google this is a endline charachter from Windows. And this seems to break some clients (Eg. Lotus Notes). With dovecot version 2.1.x I don't have this problem. Have you any solution for me? Many thanks Urban Loesch

Any issues with dsync between 2.1.7 and 2.2.9 ?
by deano-dovecot＠areyes.com 29 Jun '14

29 Jun '14

My current production system is running dovecot 2.1.7-7ubuntu1 on Ubuntu 13.04, and I'm building a new setup based on Ubuntu 14.04 with dovecot 2.2.9-1ubuntu2.1 - current standard in the repos. I'd like to use replication to get the mailstore from the old system to the new. Are there any caveats or gotchas to be aware of ? Is it possible to make it a one-way replication ? So problems or glitches on the new setup don't propagate to the old production ? Thanks - D.

Procmail to Sieve translation
by Gerhard Wiesinger 28 Jun '14

28 Jun '14

Hello, I'm trying to move from procmail to dovecot sieve. I found the translation script at http://www.dovecot.org/tools/procmail2sieve.pl It works well except the following use cases: * ^From:.*myemail@mydomain.com.* | formail -I"X-Priority: 2 (high)" -I"X-mydomain-com-seen: yes" | $SENDMAIL -oi \ myemail(a)mydomain2.com \ myemail(a)mydomain3.com :0c * ^From:.*myemail@mydomain.com.* ! +1123456789(a)mysmsprovider.com :0c * ^(To|Cc|Bcc):.*myemail@mydomain.com.* ! myemail(a)mydomain2.com myemail(a)mydomain3.com Is there a possibility to support these use cases (can be done manually)? How does forwarding to another domain work at the deliver process? :copy seems not to be supported, right? Thank you. Ciao, Gerhard

Dovecot virtual and SASL with Postfix
by Jerry 28 Jun '14

28 Jun '14

This is my first attempt to set up virtual users and sasl with Postfix. Can I use a regular password file in this format: user:{plain}password user2:{plain}password2 or do I need to use a different format? I have been trying to find an example of a virtual user SASL file, but without any luck. I suck at Googling too. All of the mail will be delivered to :/var/mail/vmail/<domain>/<user> -- Jerry

mixing Maildir and mdbox
by gustavo panizzo <gfa> 28 Jun '14

28 Jun '14

Hello i'm in the process to architect a new email system. i plan to use dovecot 2.2.9 (debian's wheezy). i would like to use maildir for 2 folders on each account (spam and no-spam) and the rest of the folders stored on mdbox. this should be opaque to my users. the reason for this, is i want to be able to train my anti-spam tools, but they read maildir or mbox, they don't read mdbox or dbox. but i want the other folders as mdbox (performance, backups, alternate storage) is there any way?, i prefer if is configurable in advance for all accounts but i could live with something that is done after account is created thanks! PD: please keep me CC'ed as i'm not subscribed to the list -- 1AE0 322E B8F7 4717 BDEA BF1D 44BB 1BA7 9F6C 6333

Just did some more scripting and got a total of 1413 distinct emails (distinct queueids) that suffered from this 'message was expunged' problem on the 36 hours i got the problems. As noted before, not even a single one of these 1413 were nrcpt=1. Problems were from nrcpt=2 or greater. So, whatever this is, it really seems to NOT affect single recipient messages. As you suspected, on those 1413 the very first recipient ALWAYS got a status=sent from dovecot/lmtp. "Message was expunged" never happened on the very first recipient delivery. About the first user (the first delivered message) checking the message right after delivery, i tried to confirm that by the logs. To make things a little easier, i used nrcpt=2 and nrcpt=3 situations, just to avoid posting lots of logs here.

Despite of that, 2nd recipient got the message successfully delivered. But we have also a delay=22 ... maybe lmtp instance had already opened the message BEFORE it was erased by the 1st user ? this delay is high, i know that and, usually, server do NOT suffer from this delays on deliveries. Anyway, during this problem period, queues were pretty large and, thus, load was very high, which i think explains this unusual delays. With these two cases, it really seems that this is somehow related to: - lmtp as delivery agent - multiple recipient messages - first (or previous users in fact) checked and deleted the message before all the recipients got the message delivery About the two parameters, maildir_copy_with_hardlinks and pop3_fast_size_lookups, i'll try to change them one at a time and try to reproduce the problems. Fact is i only had the problem with both set to yes and problems were completly vanished when both were set to no. -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertrudes(a)solutti.com.br My SPAMTRAP, do not email it

imap/pop3/lmtp proxy question/problem
by Jogi Hofmüller 25 Jun '14

25 Jun '14

Dear list, We are finally back to our task of migrating from cyrus to dovecot. dovecot mostly does what we want in terms of POP3/IMAP server. Now we are preparing for migration. The plan is to use dovecot as proxy for not-yet migrated accounts. This works wonderfully for IMAP but not for LMTP. Here's what I find in the logs when I try to deliver e-mail to the dovecot lmtp port: Jun 25 19:03:06 klee dovecot: lmtp(5037): Debug: none: root=, index=, indexpvt=, control=, inbox=, alt= Jun 25 19:03:06 klee dovecot: lmtp(5037): Connect from IP-address Jun 25 19:03:06 klee dovecot: lmtp(5037): Debug: user USER: Auth PASS lookup returned temporary failure: reason=Configured passdbs don't support crentials lookups Jun 25 19:03:06 klee dovecot: lmtp(5037): Debug: auth input: reason=Configured passdbs don't support crentials lookups Delivery works fine without proxy (lmtp_proxy = no). What I would need to do is to configure the proxy part so that POP3/IMAP uses the accounts username/password and LMTP uses a special account to deliver e-mail. This is dovecot-ldap.auth (the =proxy=y will be replaced by a field from ldap once the tests work): uris = ldaps://our.ldap.server/ tls = no auth_bind = yes base = dc=mur,dc=at deref = never scope = subtree user_attrs = =home=/srv/vmail/mail/%Lu,=uid=999,=gid=999 user_filter = (&(objectClass=posixAccount)(uid=%u)) pass_attrs = uid=user,userPassword=password,=proxy=y,=host=our.imap.server,=starttls=yes iterate_attrs = uid=user iterate_filter = (objectClass=posixAccount) dovecot -n # 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 3.14-1-amd64 x86_64 Debian jessie/sid auth_verbose = yes disable_plaintext_auth = no lmtp_proxy = yes login_greeting = Dovecot is spitze! mail_debug = yes mail_location = maildir:/srv/vmail/mail/%u mail_plugins = acl namespace { hidden = no inbox = no list = children location = maildir:/srv/vmail/mail/%%u:INDEX=/srv/vmail/mail/%u/shared/%%u prefix = shared.%%u. separator = . subscriptions = yes type = shared } namespace inbox { hidden = no ignore_on_failure = no inbox = yes list = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = subscribe special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = INBOX. separator = . subscriptions = yes type = private } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { acl = vfile acl_shared_dict = file:/var/lib/dovecot/db/shared-mailboxes.db sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap lmtp pop3" service auth { unix_listener auth-userdb { group = vmail user = vmail } } service lmtp { inet_listener lmtp { address = 172.16.16.78 port = 24 } user = vmail } ssl_cert = </etc/dovecot/server.pem ssl_key = </etc/dovecot/private/server.pem userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { mail_plugins = acl quota sieve postmaster_address = postmaster(a)mur.at } protocol imap { mail_plugins = acl imap_acl } Regards, -- j.hofmüller Gerüchtegenerator http://plagi.at/geruecht

(Please keep me CC'd, I'm not subscribed) Hi folks, I'm using dovecot 2.1.7 (from Debian stable) with sieve. I have default sieve script configured, which lives in /etc/dovecot/sieve. I use dovecot-lda running under the virtual-mail user, which does not have write access to the /etc/dovecot/sieve directory. Now, when a mail gets delivered, I get the following message in my logs. Jun 25 14:29:43 mail dovecot: lda(2001): Error: sieve: binary save: failed to create temporary file: open(/etc/dovecot/sieve/default.svbin.mail.local.18902.) failed: Permission denied (euid=2009(virtual-mail) egid=2009(virtual-mail) missing +w perm: /etc/dovecot/sieve, dir owned by 0:0 mode=0755) Jun 25 14:29:43 mail dovecot: lda(2001): Error: sieve: the lda sieve plugin does not have permission to save global sieve script binaries; global sieve scripts like /etc/dovecot/sieve/default need to be pre-compiled using the sievec tool Due to the lack of permissions, this is of course expected. However, when I then try to precompile the script using sievec, that also fails: # sievec /etc/dovecot/sieve/default sievec(root): Error: sieve: binary save: failed to create temporary file: open(/etc/dovecot/sieve/default.svbin.mail.local.18952.) failed: Permission denied (euid=2009(virtual-mail) egid=2009(virtual-mail) missing +w perm: /etc/dovecot/sieve, dir owned by 0:0 mode=0755) So, apparently sievec drops privileges to the virtual-mail user. Why does this happen? It seems kind of counter-productive - I don't see a way to properly run sievec as root now? How is this supposed to work? Now I wrote this, I realized that it might be related that I have specified mail_uid and mail_gid globally in my dovecot.conf file. Perhaps those are intended to only be put inside the protocol imap and protocol lda blocks? This would mean duplicating of this bit of configuration, which doesn't really sound nice. Gr.

ot: accepting self certs into win pc?
by voytek＠sbt.net.au 24 Jun '14

24 Jun '14

few month ago, I've got a new Dovecot/Postfix server with self issued certificate (like the previous server), transferred users, all went well EXCEPT for one user on Win/Outlook (or Outlook Express) who tells me his new PC 'doesn't want to accept certificate' (sorry, I'm short on exact details at this time) I need to get it sorted out, I expect it 'should just work' like it did for other users, BUT, before I start looking, trying to 'educate myself' better if any one has any pointers, dos or don't regarding win email clients with self certified server, pls point me that way is using IE with www.dom.com/mycert.crt good point to start ? (after copying mycer.crt to web linked directory first?) thanks, V

Wheezy Dovecot workarounds
by Steve Litt 24 Jun '14

24 Jun '14

Hi all, In switching from Ubuntu to Debian Wheezy (7.5 64bit, network install), I'm finding some surprises in getting Dovecot to work. PROBLEM: As installed, the package manager doesn't give you the dovecot executable. WORKAROUND: To install the dovecot executable, you need to follow these instructions: http://wiki2.dovecot.org/HowTo/DebianStable PROBLEM: Even when you install Dovecot, it doesn't work, as evidenced by the inability of a local email client to talk to it. Further elements of the symptom are that nmap -A -T4 LocalIPAddress, whether LocalIPAddress is the IP of eth0, or 127.0.0.1, fails to find any open ports. Telnet can't operate dovecot at port 143, and openssl can't operate it at 993. However, bizarrly, executing these same commands on a remote machine into the original machine (including accessing the machine's Dovecot from an email client) work perfectly. WORKAROUND To "solve" this problem, do the following raindance as root: ifdown lo ifup lo After the raindance, local access to Dovecot works perfectly, and all nmap commands perform as expected. LOL, hey man, don't shoot me, I'm just the messenger. SteveT Steve Litt * http://www.troubleshooters.com/ Troubleshooting Training * Human Performance

Mangesieve security question
by Vijay Rajah 24 Jun '14

24 Jun '14

Hello, I have a dovecot 2.2.6 on a Linux platform. I have configured manageseive extension. I have opened the manageseive port (4190) to entire world. (since I need my thunderbird and other clients to create seive scripts). I just wanted to know if it is ok to open that port to everyone, and get some feedback on some security measures specific to manageseive. -Thanks in advance Vijay PS: I have taken reasonable server hardening measures. This question is specific to manageseive.

Wishlist: add a variable %{x509} expanding to the client cert in Dovecot-auth
by Guilhem Moulin 24 Jun '14

24 Jun '14

Hi there, As of Dovecot 2.2.9, it's possible to enable passwordless authentication using client certificates [1]: ssl_ca = </etc/ssl/ca.pem ssl_verify_client_cert = yes auth_ssl_username_from_cert = yes (Password checking can be bypassed by returning the extra fields ‘password= nopassword’ in the passdb when the variable ‘%k’ expands to "valid".) However this requires the server admin to set up a PKI. Having a variable %{x509} expanding to the X.509 client cert in Dovecot-auth would remove such hassle and instead provide a way to manage authorized clients in the fashion of OpenSSH's ‘authorized_keys’. Postfix has a similar configuration option: relay_clientcerts [2]. There, the keys for the lookup table can be either client cert fingerprints or public key fingerprints (the digest algorithm can be configured with smtpd_tls_fingerprint_digest). I can't see why %{x509} should digest the certificate and not merely PEM-encode it, but having another %{pubkey} variable expanding to the (PEM-encoded) cert's SubjectPublicKeyInfo block would surely be useful :-) I wonder if there are other folks interested in having the client cert available in the passdb. Thanks, cheers, -- Guilhem. [1] http://wiki2.dovecot.org/SSL/DovecotConfiguration#Client_certificate_verifi… [2] http://www.postfix.org/postconf.5.html#relay_clientcerts

ACL group-override question
by Peter Chiochetti 23 Jun '14

23 Jun '14

Trying to get ACLs working, very basic setup: Virtual users are put into different acl_group via passdb. > u:{PLAIN}B::::::userdb_acl_groups=g The global acl file restricts what they can do. > * group-override=g > * group=g lr Shouldn't this mean, that the group rights override the user rights? The effect that I see though is, that the user "u" then may not do anything, not even lookup and read. The wiki text is not fully clear to me: It tells about disabling access fully (probably by specifying a non-existent group?). But this can only be one way to use group_override… -- peter

ACL group vs. owner question
by Peter Chiochetti 23 Jun '14

23 Jun '14

A hopefully simple question regarding the use of ACLs - the spirit being of taking away most permissions first and then adding them back selectively: In the global ACL declaration I have: > * owner lr > * group=SYS lrwstipekxa The owner is put into the SYS group via userdb extra field in static passwd file ("archiv" is a system user, but pam is disabled for the server): > archiv:::::::userdb_acl_groups=SYS Still, the group permissions do not get applied: > root@host:/etc/dovecot# doveadm -D acl debug -u archiv INBOX > […] > doveadm(archiv): Debug: Added userdb setting: plugin/acl_groups=SYS > doveadm(archiv): Debug: Effective uid=1002, gid=1001, home=/home/archiv > doveadm(archiv): Debug: acl: No acl_shared_dict setting - shared mailbox listing is disabled > doveadm(archiv): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/Maildir > doveadm(archiv): Debug: maildir++: root=/home/archiv/Maildir, index=, indexpvt=, control=, inbox=/home/archiv/Maildir, alt= > doveadm(archiv): Debug: acl: initializing backend with data: vfile:/etc/dovecot/dovecot-acl > doveadm(archiv): Debug: acl: acl username = archiv > doveadm(archiv): Debug: acl: owner = 1 > doveadm(archiv): Debug: acl vfile: Global ACL file: /etc/dovecot/dovecot-acl > doveadm(archiv): Info: Mailbox 'INBOX' is in namespace '' > doveadm(archiv): Info: Mailbox path: /home/archiv/Maildir > doveadm(archiv): Info: All message flags are shared across users in mailbox > doveadm(archiv): Debug: acl vfile: file /home/archiv/Maildir/dovecot-acl not found > doveadm(archiv): Info: User archiv has rights: lookup read > doveadm(archiv): Info: Mailbox in user's private namespace > doveadm(archiv): Info: Mailbox INBOX is visible in LIST My question: Shouldn't this work? (In a stock setup.) PS: when I add "* group-override=SYS" to /etc/dovecot/dovecot-acl the user will not even be able to list INBOX. PPS: As an aside, the setup also switches any sytem or /virtual/ users during login in local.conf: > userdb { > driver = static > args = uid=archiv gid=archiv home=/home/archiv user=archiv > } but I get the above result without that switching when I make it read: > userdb { > driver = static > args = home=/home/archiv > } So I suppose that it's not relevant in this case… Thank you in advance -- peter

Setting mail_attach_dir for destination on dsync
by Laeeth Isharc 23 Jun '14

23 Jun '14

Hi. What is the best way to do this, please ? I can override with -o but this applies to source as I read the docs. So I wish to do something like this dsync mirror -u myuser(a)me.com mdbox:/home/mail/myuser/mdboxcopy With either of: 1) attachments stored within message so mail_attachment_dir for dest being blank Or 2) attachments stored in a sub directory of mdboxcopy eg mdboxcopy/attach/ Timo hints that this is possible, but I cannot see how to do this, Any ideas ?

config best practice
by Egbert 20 Jun '14

20 Jun '14

Hi! We will soon start upgrading our Ubuntu mail server (running 2.0.19) from 12.04.1 LTSto 14.04 LTS. The dovecot config is still pretty much in 1.x style; one flat file called dovecot.conf. I can easily switch to a dovecot.conf with the "!include" lines and rename my flat config file to local.conf. I've tested that and it works fine. I could also try to move all lines in local.conf to the different XX-.conf files in the conf.d subdir. What is wise and best practice? Should one edit the files in conf.d? Or will the files in conf.d be overwritten on an update of dovecot? Then I'll better stick to the way of working with the dovecot.conf with the !includes and local.conf and assume that all files in conf.d are default settings. TNX for any advise!

Sis attachment deduplication
by Laeeth Isharc 20 Jun '14

20 Jun '14

Hi. Two questions: 1. Is this now reasonably stable for large mailboxes (c 2mm messages)? 2. Will this leave the filename in the message body unchanged? So for example if I have the same attachment called proposalfromvendor.pdf and proposaltoclient.pdf in two different emails, will the original names be kept ? Or will it replace the filename with some kind of numeric hash ? Many thanks. Laeeth Sent from my iPad

IMAP Chunking Thunderbird
by MrLINK 20 Jun '14

20 Jun '14

Hi, using dovecot-2.0.9-7.el6.x86_64 on CentOS release 6.5 (Final) I have an issue with thunderbird imap chunking. Some attachments are corrupted, because Thunderbird is just storing the first chunk. Since there are some workarounds by editing the "mail.imap.fetch_by_chunks" via about:config this is not the best choice for me because every client has to be edited. Is there a way to set a central value on the dovecot server (i.e disable chunking since this is not a client behaviour only)? Thanks in advance!

Suggestion: Split login_trusted_networks
by Peter Mogensen 20 Jun '14

20 Jun '14

Hi, It seems the use of login_trusted_networks is overloaded. Example: * It's used for indicating which hosts you trust to provide XCLIENT remote IP's. * It's used for indicating from which hosts you trust logins enough to disable auth penalty. (like in a webmail) However... trustwise, this is trusting two different entities. The first case you put trust in the host. In the second case, you actually put trust in the user which uses the webmail (unless of course the webmail it self implements auth-penalties). So you can't have one set of hosts which you trust for XCLIENT and another set of hosts you trust for not being the origin of brute force attacks. /Peter

Replication and namespaces
by Laeeth Isharc 19 Jun '14

19 Jun '14

Hi. Replication in dovecot is running into trouble as it is trying to sync virtual namespaces and does not like it. dsync parameters With v2.2.9+ you can configure what parameters replicator uses for the doveadm sync command: replication_dsync_parameters = -d -N -l 30 -U The -f and -s parameters are added automatically when needed. Usually the only change you may want to do is replace -N (= sync all namespaces) with -n <namespace> or maybe just add -x <exclude> parameter(s). ........ What is the description of namespace that follows -n or -x? -x virtual Or -x 0/ Where 0/ is the prefix for my virtual namespace Does not seem to stop it trying to sync the virtual namespace... What should I be doing instead? Do I need to use all the parameters above? Or can I just use the -x ? Sent from my iPa

dsync initial replication failing
by Cassidy Larson 19 Jun '14

19 Jun '14

Trying to get my new storage server synced up using dsync replication with SSH. Followed the wiki and everything works great for the initial sync, for about 4 hours, then I get some errors and it stops replicating: dsync-local(user(a)host.com): Warning: Failed to do incremental sync for mailbox INBOX, retry with a full sync dsync-local(user(a)host.com): Error: Remote command returned error 75: ssh -lusername <remote_ip> doveadm dsync-server -uuser(a)host.com -U It happened around 2am. I restarted the new server dovecot process and it started to copy back up again, and then happened about four hours later. I have about 10,000 accounts, and it chugs through the list to replicate pretty well (~300Mbps), so I know it's working. Just not sure why it's failing after it's working so great. Running 2.2.13 on both on FreeBSD. Both show this: # doveadm replicator status Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 5645 Waiting 'failed' requests 0 Total number of known users 9957 Any ideas? Suggestions? Thanks, Cassidy

I think you will hear from proponents of both styles. I would say use whatever works best for you. I personally use one dovecot.conf without any includes because I like having all my configs in one place. Less editing mutiple files, and less forgetting some configuration squirreled away in some conf.d file. Joseph Tam <jtam.home(a)gmail.com>

RFE: dnsbl-support for dovecot
by Reindl Harald 17 Jun '14

17 Jun '14

after having my own dnsbl feeded by a honeypot and even mod_security supports it for webservers i think dovecot sould support the same to prevent dictionary attacks from known bad hosts, in our case that blacklist is 100% trustable and blocks before SMTP-Auth while normal RBL's are after SASL i admit that i am not a C/C++-programmer, but i think doing the DNS request and in case it has a result block any login attemt should be not too complex setup a own honeypot and feed rbldnsd with the sources is quite easy and in case of a own, trustable RBL where no foreigners report somebody by mistake it's relieable and scales well over many machines and services as long services supporting it mod_security: http://blog.inliniac.net/2007/02/23/blocking-comment-spam-using-modsecurity…

[Dovecot] Replication with virtual users and static userdb possible ?
by deano-dovecot＠areyes.com 17 Jun '14

17 Jun '14

Is it possible to get replication working in a virtual user setup that uses a static userdb ? My environment is fairly simple and typical - there's a single system user (vmail) that owns all the home dirs (/var/mail/domain.com/user). The virtual users (userid@domain.com:secretpassword) are kept in a single file (/var/mail/domain.com/PASSWD) that's unique per domain, and referenced as a static userdb : passdb { driver = passwd-file args = scheme=plain username_format=%u /var/mail/%d/PASSWD } userdb { driver = static args = uid=vmail gid=vmail home=/var/mail/%d/%n } I know the wiki http://wiki2.dovecot.org/Replication states that user listing must be enabled, but that's not available for a static userdb. The wiki http://wiki2.dovecot.org/UserDatabase/Static also says that it shouldn't be a problem because it will use do a passdb lookup instead (except for PAM which isn't used here). Unfortunately, it's not working. I've testing with ssh : dsync_remote_cmd = ssh -l vmail %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace} mail_replica = remote:vmail@server2.domain.com as well as with straight tcp (SSL for later) mail_replica = tcp:server2.domain.com:999 /var/log/mail.err shows the problems ... Jun 3 11:30:53 server1 dovecot: auth: Error: Trying to iterate users, but userdbs don't support it Jun 3 11:30:53 server1 dovecot: replicator: Error: User listing returned failure Jun 3 11:30:53 server1 dovecot: replicator: Error: listing users failed, can't replicate existing data Anyone else have it working ? I'm sure it's something simple that I've just overlooked. Thanks - D.

Accessing a user mailbox from another user
by Angel L. Mateo 17 Jun '14

17 Jun '14

Hello, I'm looking for something maybe similar to master password but for final users and I don't know if there is already a way I could do it with dovecot. I have accounts that are used by a set of users who know their password. But I now want to remove this shared password and the users has to access to this shared account with their own password. Using shared folders is not an option (at least, not the first option) because of the behaviour our users are familiar with, such as: * They have and manage different sieve filters for the account * They have thier own Sent, Drafts, SPAM... for this shared account and their email client recognizes them as it (because they have its own account). What I'm looking for is something similar to master password, but for a user identifying as another regular user, not the "master" one. Do you know if there already is a way to configure a similar behaviour? I'm planning to configure an user and authentication backend (maybe pam) that gets users as <realuser>$<finaluser> and the realuser password, checks if <realuser> should access to <finaluser> and then returns <finaluser> mail location to dovecot.

Procmail wiki text -- don't muck with SENDMAIL
by era eriksson 16 Jun '14

16 Jun '14

I tried to edit http://wiki2.dovecot.org/procmail but got stuck on the TextCha. Approaching this list instead seems to be a time-tested secondary approach, and I wasn't completely comfortable making these changes without discussion anyway. So here goes. The SENDMAIL= assignment is not only irrelevant, but actually wrong. The note down in the update section about Ubuntu explains the problem well enough, but it applies to all the sections on the page. My proposed edit was to simply remove SENDMAIL and SENDMAILFLAGS from all the recipes on the page, and then remove the Ubuntu section altogether, because it would no longer add anything useful to the page. If somebody in the Dovecot community with edit access to the wiki wants to implement this change, I would be grateful on behalf of the people who try to use Procmail with Dovecot. -- If this were my real .signature, it would suck less. Well, maybe not.

[Dovecot] Pigeonhole and dsync replication not replicating 'SETACTIVE' for a sieve script
by Skeffling 16 Jun '14

16 Jun '14

Hello, I'm testing dovecot replication alongside pigeonhole and liking it. Dovecot v2.2.13 Pigeonhole v0.4.3 If I create or edit a sieve script on one server (via managesieve, using the thunderbird plugin as it happens) then it does get replicated to the other - great! However, if I set a script to be active (SETACTIVE) on one side then this is not being replicated across to the other server. Is this a known issue? Thank you! -- Andrew

[Dovecot] doveadm index - Bug or expected behaviour?
by Bruno Galindro da Costa 13 Jun '14

13 Jun '14

My ldap config is using the variable %d in base search for domain replacement when dovecot will search for users in LDAP. Its works fine for dovecot operation. But, for doveadm index, not. It ignores that variable and tries to pass a base search without domain. So, the search will not working.

Subject tag [Dovecot] is gone
by Timo Sirainen 13 Jun '14

13 Jun '14

I've actually been thinking about it almost since the beginning. It's just been annoying waste of space on my screen. And more importantly nowadays it's also breaking DKIM/DMARC signatures. So if somebody still uses Subject-based filtering it's about time to switch to List-ID header based filtering now. Another thing I'm wondering about is if I should allow text/html parts, because removing them will also break the DKIM signatures. Or mainly I'd like to allow only multipart/alternative with text/plain + text/html, but I don't think I can configure Mailman to support that.

display SSL version?
by Zube 13 Jun '14

13 Jun '14

Sorry for the bother, but is there any way to poke or prod or query dovecot so that it will reveal what version of SSL it is currently using? dovecot --build-options tells me that openssl is there, but not the version. ldd on any of the binaries in libexec comes up empty. I can get the version and what directory it is looking at by: strings ssl-params | grep -i ssl but that is kludgy. CentOS 5, dovecot 2.2.13. Thanks for any help. Cheers, Zube

A solution : dsync(someuser) Error: Mailbox GUIDs are not permanent without index files
by James Rogers 12 Jun '14

12 Jun '14

While migrating from mbox to maildir using dsync, I kept running into a brick wall. Some folders would not sync. The message in stderr was: Error message GUID: Mailbox GUIDs are not permanent without index files. This is what solved things for me. I hope this might help someone. Let me know if I'm completely off sides. When working with dsync to migrate from mbox to maildir format mailboxes, I kept running into the error: dsync(someuser): Error: Couldn't get mailbox Drafts GUID: Mailbox GUIDs are not permanent without index files dsync(someuser): Error: Couldn't get mailbox Junk E-mail1 GUID: Mailbox GUIDs are not permanent without index files dsync(soemuser): Error: Couldn't get mailbox TO DO LATER - US GUID: Mailbox GUIDs are not permanent without index files dsync(someuser): Error: Couldn't get mailbox Notes GUID: Mailbox GUIDs are not permanent without index files dsync(someuser): Error: Couldn't get mailbox Orders Pending GUID: Mailbox GUIDs are not permanent without index files dsync(someuser): Error: Couldn't get mailbox Junk E-mail GUID: Mailbox GUIDs are not permanent without index files dsync(someuser): Error: Couldn't get mailbox Server Mgmt+Config GUID: Mailbox GUIDs are not permanent without index files The error messages were helpful, but it would be nice to know what prevented the creation of the indexes in the errors (permissions, settings, disk space, etc.). I finally figured it out semi-randomly when I dumped my doveconf file using doveconf -n, and saw: mbox_min_index_size = 100 k I felt very um... happy? And not too bright. The following made my problems go away, and the sync worked flawlessly. mbox_min_index_size = 0 I guess it's best to set this using dsync -o'mbox_min_index_size=0' Mail now converts quickly and completely even for 0 length mailboxes (i.e. empty folders are created). Also, I would like to note that mb2md.pl should not be used to convert mbox to maildir. The regex used to split mboxes will fragment messages. mb2md.pl uses: if ( /^From / And in the very least, the following would be less harmful: if ( /^From\s+(\S+.*(a)\S+.*|MAILER.DAEMON)\s+.*$/ I love dovecot. I knew it must be something bone-headed I just wasn't seeing. And now I can go get some rest. --James W. Rogers

lazy_expunge mangles dovecot-acl-list
by Christoph Bußenius 12 Jun '14

12 Jun '14

Hi, I think I found a bug in Dovecot 2.1.17 and 2.2.13. In our setup, sometimes ACLs stop working because "dovecot-acl-list" is replaced by an empty file. We found that lazy_expunge is connected to this. To reproduce, create ACLs for "user1" in a folder. Put a mail in that folder and expunge it, so that the folder will be created in the "expunged" namespace. For instance, # cat user1/mail/mailboxes/folder/dbox-Mails/dovecot-acl user=user2 keilrwts # cat user1/mail/dovecot-acl-list 1350914868 folder # doveadm -f flow fetch -u "user1" 'guid' mailbox _EXPUNGED.\* # ls -l user1/mail/dovecot-acl-list -rw------- 1 vmail vmail 0 2014-06-12 11:40 user1/mail/dovecot-acl-list You see that we have used doveadm to list the expunged namespace, which has emptied the "dovecot-acl-list" file.

Guys, I need to parse my dovecot log files with logstash grok patterns. Is there any document specifying the patterns used by dovecot to write it's logs? I need to find all the log possibilities that could be writed to log files by dovecot. So, if a document like that exists or if anyone could answer my question, I'll could make the parser with less difficult. -- Att. Bruno Galindro da Costa

Converting mailboxes from one Maildir format to another
by Patrick C 12 Jun '14

12 Jun '14

I am currently running dovecot 2.0.9 on a CentOS 6 server with the following layout for mailboxes: mail_location = maildir:~/Maildir I would like to change the layout to this format to match the output of other software packages such as offlineimap, mbsync, etc: mail_location = maildir:~/Maildir:LAYOUT=fs:INBOX=~/Maildir/INBOX Is there a way to convert the mailbox layout for all mail accounts currently on the server? I was looking at dsync, but there aren't any Maildir <--> Maildir examples. I was also looking at potentially writing a script to manually rename directories/move files around to match the new format, but wasn't sure whether that would mess with UIDs or other dovecot internals. pat patrickc81(a)gmail.com

Safe to downgrade 2.2 to 2.1?

Hi, is it safe to downgrade Dovecot 2.2 to 2.1 (in my case 2.2.13 to 2.1.17 with mdbox format) or will there be troubles with index files and backup/restore is recommended? Unfortunately with 2.2+ it is not to be possible to use acl + lazy_expunge together anymore, so downgrading is the only option for me... @Timo, please fix acl + lazy_expunge in 2.2 if you find some time.

Change index location problem

11 Jun '14

Hi All, I was unable to change location of Dovecot indexes. Currently they are under /var/vmail/%d/%u, but I want to change them to /media/ephemeral0/%u I've changed conf line in /etc/dovecot/dovecot.conf: mail_location = maildir:/var/vmail/%d/%u:INDEX=/media/ephemeral0/%u and setup permissions of /media/ephemeral0 to dovecot:dovecot, tried also vmail:mail (which is default user for e-mails) and also tried with 777 on all dirs, but Dovecot is keeping creating indexes on the old location. I tried moving them from old to new location, but Dovecot recreates them on the old location. Details: # dovecot --version 2.0.9 # doveconf -a | grep location mail_location = maildir:/var/vmail/%d/%u:INDEX=/media/ephemeral0/%u Has anyone experienced something similar, any solution for this?

Re: Subject tag [Dovecot] is gone

On 6/9/2014 7:26 PM, Timo Sirainen wrote: > The main reason is DKIM, which is starting to be a real problem. I have not used DKIM much. My mail server and client mostly deal with SPF. I have a filter that colorizes messages that have no SPF or a missing DKIM or bad DKIM signature. I *have* noticed that a lot of messages from the list get marked in such manner, but it never really bothered me and I never thought about it much. Now I understand why that happens (the [Dovecot] identifier in the subject). When trying to solve a problem, the first thing is to correctly identify the problem. You cannot solve a problem if you do not even know what it is. The underlying problem is to identify and classify emails as ones you want and ones you do not want. This is not easy and involves reading a person's mind. A person may, depending on their mood, classify the same email differently at different times, which complicates things. DKIM assumes that you can, in many cases, classify emails this way based on authenticating the *domain* of the sender. This has some serious flaws in that it does not address this issue, even though it purports to. One way to classify an email as "wanted" is if it comes from someone you know and want to communicate with. Signing based on a domain does nothing to address this. If my girlfriend is judy(a)yahoo.com, I want to receive her emails. That does not means I want to receive all emails from the yahoo.com domain. I do not want someone else to impersonate her. If later, we break up and I no longer want to receive her emails, DKIM does nothing to help with that, either. That could be OK if such functionality is beyond its scope. DKIM erroneously bundles sender authentication with message validation. I want to know that it really was judy(a)yahoo.com that sent me the message and not someone trying to impersonate her. However, as a separate function, I would like to know that the message I received is not the one she sent. These functions should not be integrated. As it is now, if the signature does not verify, I do not know why. Was the sender spoofed? Was some part of the message modified in some way? And just for the record, I believe that the subject line should conceptually be treated as part of the message, along with the date. DKIM is too strict. If I want to present a legal document (email) in court, I may want to prove that the document I present to the court is exactly as it was when it was sent to me. However, this is not a common occurrence. The real world is messy and imperfect and often, changes to emails are innocuous and legitimate. Mailing lists are an example of this. A mailing list or anti-virus scanner *should* be able to add a footer or add a mailing list identifier to the subject line, as long as those changes can be marked as later additions that the original sender is not accountable for. An email program should make it clear to the recipient which parts are not accountable to the original sender. I am not proposing a new standard, simply pointing out that breaking an established protocol (by removing the [Dovecot] subject identifier) because of a flawed anti-spam system is not in people's best interest. Can a spammer spoof messages from the list? Sure. Has it happened? Not that I am aware of. Is it a problem? Not so far. So why, then, make people go through all this trouble of setting up new filters and rules, mail routing, software upgrades, etc, just to appease a standard that is clearly broken? Dem

replication with plugin won´t work
by Florian Schaal 11 Jun '14

Hi all, i try to setup a master-master replication with dovecot / dsync. I´m using virtual-users. When I call doveadm sync -A remote:vmail@server2 new mails are copied to the second server, but new messages from server 2 not on Server 1. To fix this i run doveadm sync -A remote:vmail@server on the 2nd server But I want that it works with dovecot / dsync (see my config at the end - identical on bot servers, only mail_replica is different). I added some services regarding http://wiki2.dovecot.org/Replication If i send a local mail on one server it will not be replicated to the other server until i run doveadm sync. Maybe i just missed some steps in my setup? doveadm user '*' displays the right users on both servers. === docecot.conf === # 2.2.13 (7b25994a8cb7): /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-042stab076.8 x86_64 Debian 7.5 auth_mechanisms = plain login ntlm disable_plaintext_auth = no dsync_remote_cmd = ssh -p 4711 -l%{login} %{host} doveadm dsync -u%u listen = *,[::] log_timestamp = "%Y-%m-%d %H:%M:%S " mail_debug = yes mail_plugins = " notify replication" mail_privileged_group = vmail passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { mail_replica = remote:vmail@server2 quota = dict:user::file:/var/vmail/%d/%n/.quotausage replication_full_sync_interval = 1 hours sieve = /var/vmail/%d/%n/.sieve } protocols = imap pop3 service aggregator { fifo_listener replication-notify-fifo { mode = 0666 user = vmail } unix_listener replication-notify { mode = 0666 user = vmail } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } user = root } service config { unix_listener config { user = vmail } } service doveadm { user = vmail } service imap-login { client_limit = 1000 process_limit = 500 } service replicator { process_min_avail = 1 } ssl_cert = </etc/postfix/smtpd.cert ssl_key = </etc/postfix/smtpd.key userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota pop3_uidl_format = %08Xu%08Xv } protocol lda { mail_plugins = sieve quota } === docecot.conf === regards Florian

[Dovecot] Can't get authentication for masterusers on Mac OS X Server 10.6.8
by Gilles Celli 11 Jun '14

11 Jun '14

Hi dovecot masters, This is my first post here, since I desperately need some advices from the dovecot community. I've tried to get an answer on the Apple Forums but til now no luck....here we go: I've tried to sync our users emails (Mac OS X Server 10.6.8 Snow Leopard with dovecot 1.1.20-apple0.5) via imapsync to our new server by using the masterusers authentication method on the old 10.6.8 server... The main problem on OS X Server 10.6.8 is that dovecot 1.1.20 uses the OD (OpenDirectory) driver (well I think), so that when following the directions of Master users/password from this page I can't login with the http://wiki1.dovecot.org/Authentication/MasterUsers I couldn't find anything on the OD driver directive....the dovecot 1.1.20-apple build doesn't even have the shadow driver built in (see below the dovecot --build-options), so that passdb shadow {} won't work anyway I always get NO Authentication failed, when trying the following: >telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK Dovecot ready. 1 login user1*mailadmin PASSWORD 1 NO Authentication failed. I've tried also to add a Post-login scripting like described here, but no luck either: http://www.stefanux.de/wiki/doku.php/server/dovecot Does someone know how to fix my migration issue ?

Dovecot auth NTLM
by dovecot.lista＠palacio.cu 10 Jun '14

10 Jun '14

Hello, this is my first email to the list... i´m configuring Dovecot with NTLM authentication, at least this is what i wanted, but i´m having a few problems. 1-I made my configuration following the steps from this howto http://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm from the dovecot official site, but my dovecot´s version is 2.1.7 and the tutorial dovecot´s version is 1.1.16. But, the fact is that when i enter to the wiki1, for the version 1.x i found that all the howtos are obsoletes and the tutorial for the version 1.x is the same for the 2.x version, so this howto is not trustful.... but, there is not another one. 2-When i implement it all seems to work OK, but the communication between dovecot and the helper in "/usr/bin/ntlm_auth". I made the tests with the binary(/usr/bin/ntlm_auth) and i got the right answers from it, and i also made the test with the tool wbinfo and were successful. During the tests i was monitoring the logs of my Domain Controller (The server from where i want to authenticate) and it logged all the requests i made however when i try to authenticate with dovecot in my Domain Controller nothing is written in the logs... then i get to the conclusion that Dovecot is not communicating with the helper, and of course in dovecot´s logs appears: auth: Info: winbind(?,10.10.10.10): user not authenticated: NT_STATUS_UNSUCCESSFUL As i said, my friends, there is no any other tutorial or howto in internet, at least i did not see it. I´m asking for your help... if any of you have configured Dovecot to auth against NTLM, please tell me how. Im working on Debian Wheezy and Dovecot 2.1.7. PS:Please forgive my English i speak Spanish

Dovecot Configuration for access with GSSAPI / Kerberos

Hi Dovecot-Mailinglist! I try to install a new Dovecot-Server with Kerberos-Authentification (Kerberos-Server is already authenticating user-account ).

[Dovecot] Issues with VANISHED CHANGEDSINCE
by Michael J Rubinsky 09 Jun '14

09 Jun '14

I've been seeing the following wonky behavior with Dovecot. Currently this is with Dovecot 2.0.19, but I was also seeing it in earlier versions as well, including versions from the 1.x series. Some background, this is from Horde's ActiveSync library, when it is trying to determine what UIDs have recently been expunged. I can guarantee that when this command was sent, there was only one or two emails that were removed since the provided MODSEQ value. C: 8 UID FETCH 1:* UID (VANISHED CHANGEDSINCE 587742) S: * VANISHED (EARLIER) 1:119944,119947:123482,123484:128043,128045:130388,130390:130456,130458:132127,132129:135832,135834:136201,136203:136301,136303:136316,136318:138502,138504:140099,140101:141908,141910:142607,142609:142744,142746:142865,142867:143160,143164:143173,143176:143179,143181:143187,143189:143190,143192:143195,143197:143270,143272:143273,143275:143280,143282:143302,143305:143307,143309:143318,143320:143333,143335:143337,143339:143341,143343:143375,143377:143400,143402:143551,143553:143637,143640:143706,143708:144069,144071:144178,144180:144307,144309:144316,144318:144329,144331:144931,144933:144983,144985:145000,145002:145069,145071:145072,145074:145132,145136:145178,145180:145191,145193 Also, to verify it wasn't something screwy with my server, Michael Slusarz provided me with this from his server: <quote> There's definitely something wonky going on in the code. There's a certain tipping point of modseqs where the values become incorrect. For a mailbox with HIGHESTMODSEQ of 54004, I see this: a uid fetch 1:* UID (VANISHED CHANGEDSINCE 53881) * VANISHED (EARLIER) 1:37308,37310:40788,40791:41032,41034:41083 a OK Fetch completed. b uid fetch 1:* UID (VANISHED CHANGEDSINCE 53882) * VANISHED (EARLIER) 41029:41030,41047:41083 b OK Fetch completed. </quote> Thanks for any guidance. -- mike The Horde Project (www.horde.org) mrubinsk(a)horde.org

[Dovecot] checkpassword memory limit
by a 08 Jun '14

08 Jun '14

Hi. I am trying to authenticate dovecot from a wordpress database. I was thinking of using the checkpassword script to start a cli php script. That php script would then include the necessary wordpress functions, do the auth (find the wp username from user database using the email address, and authenticate with the user/pass), and return the result to the checkpassword script. I made the above scripts (the php script will be used to authenticate some other services too), and when I run them "by hand" (even with "sudo -u dovecot ..."), it works. But, when the dovecot runs them, the php runs out of memory. After a lot of debuging, I find out that when the dovecot starts the checkpassword script, it makes a 250kB memory limit. But it is not enough for the php script, it needs 14MB. I tried to put a "ulimit -v 16777216" into the checkpassword.sh, but it doesn't work.Is there some hardcoded limit in the dovecot itself? And if there is, could it be somehow changed?I am using a simple D ebian Wheezy LAMP, and installed everything from repo. Thanks for every idea.

[Dovecot] Authentication Failure (newbie)
by Danny Gorton 08 Jun '14

08 Jun '14

Greetings, I'm am learning about running a mail server and I set up a brand new Ubuntu 14.04 server with postfix and dovecot. I had some initial problems with dovecot not starting, and then with not having proper permissions/access to the various directories and files and pipes, etc, and in the process starting to learn how this thing works. After searching in web-land I seem to have overcome those issues and dovecot and postfix both start and accept connections now (http://wiki2.dovecot.org/TestPop3Installation) However when I check to see if I can authenticate I get Authentication Failed. At the time of these login attempts there are no messages added to syslog or mail.log, dovecot log entries are below. Note I redacted my test user and password values to 'xxxxx', and my domain value to 'domain.com'. Also I'm testing with my plain text password, but I've tried using AUTH PLAIN <base64 encoded uid/pwd>. I have also tried the setup with a default auth domain, and I've tried authenticating with and without the domain name as part of the user name, with the same results. I added the debug settings and disable_plaintext_auth = no to try to solve this issue. Here is my test command set: xxxxx@apacweb:~$ sudo doveadm user xxxxx field valueuserdb lookup: user xxxxx doesn't exist and : xxxxx@apacweb:~$ telnet localhost 110 Trying ::1... Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Dovecot (Ubuntu) ready. user xxxxx +OK pass xxxxx -ERR [AUTH] Authentication failed. Here is a cut from the dovecot log: 2014-06-08 01:22:10 auth: Error: passwd-file(xxxxx): stat(uid=vmail gid=vmail home=/home/vmail//xxxxx /etc/dovecot/users) failed: Address family not supported by protocol I figure this is the root cause of this issue and the solution to it is supposedly to tell dovecot to not listen on IPv6 (listen = *), but I did that and it didn't help (see config). Here is a cut from the dovecot.info log: 2014-06-08 00:16:25 auth: Debug: auth client connected (pid=3131) 2014-06-08 01:22:10 auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth 2014-06-08 01:22:10 auth: Debug: Read auth token secret from /var/run/dovecot//auth-token-secret.dat 2014-06-08 01:22:10 auth: Debug: passwd-file /etc/dovecot/passwd: Read 1 users in 0 secs 2014-06-08 01:22:10 auth: Debug: master in: USER 1 xxxxx service=doveadm 2014-06-08 01:22:10 auth: Debug: userdb out: NOTFOUND 1 Here is my dovecot config: # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.13.0-24-generic x86_64 Ubuntu 14.04 LTS ext4 auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain cram-md5 auth_verbose = yes base_dir = /var/run/dovecot/ disable_plaintext_auth = no info_log_path = /var/log/dovecot.info listen = * log_path = /var/log/dovecot log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = maildir:/home/vmail/%d/%n/Maildir passdb { args = /etc/dovecot/passwd driver = passwd-file } protocols = imap pop3 service auth { executable = /usr/lib/dovecot/auth unix_listener /var/spool/postfix/private/auth-client { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { group = postfix mode = 0777 user = postfix } user = vmail } service imap-login { chroot = login executable = /usr/lib/dovecot/imap-login user = dovecot } service imap { executable = /usr/lib/dovecot/imap } service pop3-login { chroot = login executable = /usr/lib/dovecot/pop3-login inet_listener pop3 { address = * port = 110 } inet_listener pop3s { address = * port = 995 } user = dovecot } service pop3 { executable = /usr/lib/dovecot/pop3 } ssl = required ssl_cert = </etc/ssl/certs/smtpd.crt ssl_key = </etc/ssl/private/smtpd.key userdb { args = uid=vmail gid=vmail home=/home/vmail/%d/%n /etc/dovecot/users driver = passwd-file } valid_chroot_dirs = /var/spool/vmail protocol pop3 { pop3_uidl_format = %08Xu%08Xv } I'm sure I've done something stupid, but after thrashing about for some days I haven't been able to figure out what it is.

[Dovecot] Running dovecot under Cygwin
by Manolis Spanakis 06 Jun '14

06 Jun '14

Hi, In http://wiki2.dovecot.org/DovecotFeatures I found the following statement regarding devcot support of cygwin: Cygwin works after a few code changes, but doesn't support SCM_RIGHTS I downloaded "dovecot-2.2.13.tar.gr" and tried to compile it under cygwin version 1.7.30 (0.272/5/3) CYGWIN_NT-6.3-WOW642.580 (32-bit). As I executed the: $./configure I got the following error: error: fd passing is required for Dovecot to work If I bypass this error by changing "configure" I get no other errors either in "configure" or "make". It seems that "src/lib/fdpass.c" is the only library incompatible with cygwin. Is there any file version available that provides a solution? Thank you in advance, Manolis Spanakis

[Dovecot] CRAM-MD5 authentication memory leak problem.
by Kenji Tonami 06 Jun '14

06 Jun '14

I used dovecot Auth daemon for postfix SMTP Auth. I saved clear password to OpenLDAP, then I set up that as the password will be used. There ware no trouble when authentication had sucessed. But when authentication failed by using "CRAM-MD5", it caused increasing memory allocation of dovecot auth daemon. In case of using "PLAIN" or "LOGIN", there were no problem even if authentication had failed. I got same result on dovecot-2.0.9(RHEL6) and dovecot-2.2.13. Does anyone know similar case? I tried restarting dovecot Auth daemon by using service_count parameter in service auth settings. When authentication failed, message on postfix was as follows: ** 535 5.7.8 Error: authentication failed: "CRAM-MD5 string" When authentication failed and restarting dovecot auth daemon at the same time, message on postfix was changed as follows: ** 535 5.7.8 Error: authentication failed: Connection lost to authentication server It looks like that the failed authentication request is suspended by restarting auth daemon. -- config (10-auth.conf) auth_mechanisms = plain login cram-md5 -- -- config (10-master.conf) service auth { executable = auth unix_listener /var/spool/postfix/private/auth { mode = 0666 user = postfix group = postfix } } -- -- auth-ldap.conf.ext passdb { driver = ldap args = /etc/dovecot/ldap-passdb.conf.ext } -- -- ldap-passdb.conf.ext host = xxx.xxx.xxx.xxx dn = LDAP Manager DN dnpass = Manager DN password base = ou=mail,dc=xxxxxx,dc=xx scope = subtree pass_attrs = mailID=user,mailClearPassword=password pass_filter = (mailID=%u) auth_bind = no default_pass_scheme = plain -- Thanks. -- Kenji Tonami

It turned out to be a TCP scaling problem. If a router/firewall drops packets with a TCP scaling option set, the endpoints disagree on how many outstanding non-ACK packets are allowed, resulting in timeouts. http://support.microsoft.com/kb/935400 http://en.wikipedia.org/wiki/TCP_window_scale_option The Microsoft KB does hint those versions of Outlook may be affected, but I can't figure out why there would be a difference between Dovecot 2.1 and 2.2.

[Dovecot] Sharing folder with others
by Claudinei Santos 05 Jun '14

05 Jun '14

Hello, The sharing folders with dovecot works, but when the user that i shared the folder reads any e-mails in the folder, all my subcribed folder (the folders that i do not shared with this user) is unsubcribed from my account. The only folders that remains is the default ones ( inbox, trash, spam and sent) and the folder that i shared with that user. my configurations: # separator for master-users, example: "login_user*master_user -> user(a)domain.tld*masteruser auth_master_user_separator = * passdb passwd-file { driver = passwd-file args = /etc/dovecot-masterusers master = yes } namespace private { type = private separator = / prefix = #location defaults to mail_location. inbox = yes } namespace shared { type = shared separator = / prefix = Share Folders/%%u/ location = maildir:/var/spool/mail/vmail/%d/%%n:INDEX=/var/spool/mail/vmail/%d/%n/shared/%%u subscriptions = yes list = children } # cat /etc/dovecot-postlogin #!/bin/bash export MASTER_USER="$USER" exec /usr/lib64/dovecot/imap "$@" Can someone help me out with this?

[Dovecot] director with multiple instances

I'm experiencing some problems similar to those described in http://dovecot.org/list/dovecot/2012-July/137250.html except with 2.0.9.

[Dovecot] What are the options for HA and\or replication and\or storage?
by Eliezer Croitoru 05 Jun '14

05 Jun '14

I am considering couple options of converting a current service into a HA using multi servers or any other solutions. The point is that I am thinking about the options and which I am looking for. NFS can be a storage which has it's own pros and cons. There is the option of DRBD but as of now it's limited for two hosts. What options do exist out-there as a solution? The main issues are that the current service is based on Maildir and is on one server with resierfs. The service is composed of one host with 50k users couple disks in raid6. On the same machine we have postfix as mailer. I would like to hear about HA environment that I can use to replicate the boxes. My basic research leaded me to smtp on one host or more and using lmtp to send the messages to dovecot o another host which will have a replicated host and will be used with storage system based on ISCSI or NFS. Any other idea to enhance the current one or to replace it is more then just welcome. Thanks, Eliezer

[Dovecot] General questions about TCP replication with dsync
by Patrick De Zordo 05 Jun '14

05 Jun '14

Hi Guys, I would like to question why I see this errors in my logs. Let explain me! Dovecot version: 2.2.9 (on Ubuntu 14.04 LTS) Ive configured our dovecot servers (2 servers) to do the TCP replication with dsync. This is working flawless. 1. Question: In logs I can see this errors on every sync (on the slave server / server without changes which should be updated): ---8<----------------------------------------------------------------------- ---------------------------------------------------------------------------- ---- dsync-server(email(a)example.com): Error: net_connect_unix(/var/run/dovecot/replicator-doveadm) failed: Permission denied ---8<----------------------------------------------------------------------- ---------------------------------------------------------------------------- ---- Googling a bit gave me the information This should be normal..? Well ok, errors in logs are not nice to see, but can someone confirm this is really ok? Timo? 2. Question (much more important): We are using sieve scripts for our users, they are replicated to the replica-host but this errors appears in logs on every synchronized message: ---8<----------------------------------------------------------------------- ---------------------------------------------------------------------------- ---- dsync-server(email(a)example.com): Error: Failed to access mailbox dovecot/sieve: Internal error occurred. Refer to server log for more information. dsync-server(email(a)example.com): Error: stat(/var/vmail/example.com/email/.dovecot.sieve/tmp) failed: Not a directory ---8<----------------------------------------------------------------------- ---------------------------------------------------------------------------- ---- So whats going on there? This is strange and should not be, right? Any hints? Thank you very much! --------------------------------------------------------------------- Mit freundlichen Grüßen / Distinti saluti / Kind regards De Zordo Patrick patrick(a)spamreducer.eu

[Dovecot] IMAP copy fails because the mailbox size of user1 is exceeding the quota limit of user2??
by Katja Wegner 05 Jun '14

05 Jun '14

Hi all, I do have a mailbox-quota problem in dovecot 2.0.19 that is beond my understanding. Could someone pls. give me a hint. - user1 max. mailbox quota is set to 1GB, the current mailbox size of user1 is 15MB - user2 max. mailbox quota is set to 10MB, the current mailbox size of user1 is 10kB - user1 shares the folder 'shared_folder' to user2 with all rights (read, write ...) - user2 has subscribed to 'shared_folder' the problem: - user2 tries to move a mail (20kB) to the shared folder via telnet: ". copy 1:1 shared/user1/shared_folder" - it fails with: "NO [OVERQUOTA] Quota exceeded (mailbox for user is full)" - copying the same mail to a local folder of user2 works without problems. - After I raised the max. mailbox quota of user2 from 10MB to 16MB it was possible to move the mail to the 'shared_folder' of user1. It looks like the copy operation fails because the mailbox size of user1 is exceeding the quota limit of user2! Is this possible? Is this a bug?

[Dovecot] attachment sis + EMLINK (too many links) = segfault bug (2.2.12)
by Pavel Stano 05 Jun '14

05 Jun '14

Hi, we use attachment dedup with lots of emails (still migrating to it from maildir). We use netapp storage with wafl filesystem over nfs. Problem is that netapp has hard limit of 100k hardlinks to one file. And we encountered it. Problem is that dovecot start do segfault (lmtp,dsync,pop3 etc) when it happend when tried to deliver new emails with that attachment. Here is strace of dsync: 6740 link("/nfsmnt/mailatch1/f9/10/hashes/f9108ddaa156ac15738e41ed3bedec1eda50175d", "/nfsmnt/mailatch1/f9/10/f9108ddaa156ac15738e41ed3bedec1eda50175d-7bb7a20ddb598853541a000028db4a9f") = -1 EMLINK (Too many links) 6740 --- SIGSEGV (Segmentation fault) @ 0 (0) --- ls -lh: -rw------- 100000 vmail vmail 4.7K Apr 28 16:54 /nfsmnt/mailatch1/f9/10/hashes/f9108ddaa156ac15738e41ed3bedec1eda50175d We were using mail_attachment_min_size=4kb, we solve it by increasing it to 8kb. It would be nice to somehow fix this problem. Like not crash when EMLINK happend and maybe do not deduplicate attachments but deliver email without dedup. Or create second file in hashes/ and start hardlinking it instead of original. AFAIK ext4 has also hard-link limit 64k (http://en.wikipedia.org/wiki/Hard_link#Limitations_of_hard_links) So this can happen to anyone with lots of emails.

[Dovecot] Plugin mail-filter tangles
by Stanislas SABATIER 05 Jun '14

05 Jun '14

System installed : Dovecot 2.2.12 as IMAP server and Postfix as MTA. Dovecot and Postfix connected via LMTP + Dovecot mail plugin 'mail-filter' to encrypt/decrypt emails on the fly with public/private users' RSA keys. Case study : You have 3 (virtuals) users belonging to 3 different domains, all managed by your Dovecot server. One of these users is connected to Dovecot with MUA Thunderbird, and he's writing an email to someone outside of yours domains, but he puts the two others users' email addresses in CC : mail from user1(a)domain1.dovecot --> to: someone@outside, CC: user2(a)domain2.dovecot, user3(a)domaine3.dovecot What happens (as far as I can understand) : The email is submitted to Postfix : one copy is delivered outside, the other is passed to Dovecot via LMTP for user2 & user3 @dovecot Dovecot is handling the final delivery, through mail-filter plugin as follow : 1. both users contexts are created from user_db queries 2. mail-filter plugin is init for user2 3. /mail_user_created/ for user2 4. mai-filter plugin arguments are parsed for user2 5. â¦/mail_allocated/ then /mail_save_begin/ for user2 (at this stage, the email is encrypted with users2 params) 6. Dovecot tells to LMTP that mail for user2 is delivered 7. then, â we are still in user2 context â, an other /mail_allocated/ is run, followed by a /istream_opened/ 8. mail user context is swithed to user3 --> /mail_user_created/ --> plugin's args parsed --> â¦ /mail_allocated/ 9. andâ¦ Dovecot tells to LMTP that mail for user3 is delivered So, it appears that Dovecot is re-using user2's email to pass it to user3 by opening an istream in user2's context. In my configuration, Dovecot can't do that because it has not the user2's private rsa key to reopen the email it has just encrypted, so it passes the email to user3 with user2 encryption params. Final result : user3 is receiving the email encrypted with user2's rsa key ! Problem : how to force Dovecot to deinit then reinit mail-filter plugin for each user to be sure that each email is encrypted with the right key before it is saved to users' mailboxes ? Thank you in advance for your help. Stan.

[Dovecot] SQL passdb, LDAP userdb
by Kristof Bajnok 05 Jun '14

05 Jun '14

Hi, in my current setup, LDAP authentication + userdb works fine. I'd like to integrate Dovecot with Shibboleth. I have a custom module at the IdP (*) that inserts short-time tokens to an SQL table at user authentication, and I want Dovecot to use the token table for passdb but keep LDAP for storing the userdb (uid, quota, etc) I thought it was simple as omitting the sql user_query, but I got: Warning: mysql: Query failed, retrying: Table 'webmail.users' doesn't exist Error: sql(user@domain,ipaddr): User query failed: Table 'webmail.users' doesn't exist (using built-in default user_query: SELECT home, uid, gid FROM users WHERE username = '%n' AND domain = '%d') Do you have any hints how to do this? Thanks, Kristof (*): in SAML there is an Identity Provider that does user authentication, which is separated from the services

Hi, in dovecot documentation i try to implement quota per users. i added dovecot-ldap.conf file user_attrs = homeDirectory=home, uidNumber=uid, gidNumber=gid, mailbox=mail, quota=quota_rule=*:bytes=%$ and i see in logs quota(quota_rule=*:bytes=%$)=*:bytes=241800 Debug: Added userdb setting: plugin/quota_rule=*:bytes=241800 but still mail is delivering , i'not sure other settings about 20-imap.conf and 20-pop3.conf from documentation. what is the correct steps for this? thanks in advance -- Selçuk YAZAR

UID 26624 is a valid user ('info' of domain14552) but under a compleltly different domain name (hamish is under domain25367). However that user has also not logged in around the time the ownership was changed. There is no relevance to the two users, except that they exist on the system and for some reason this issue happened to the hamish user. The NFS server does not know about the UIDs, it just provides the numeric IDs which is translated on the dovecot/exim servers by NSS and Dovecotr using the replicated MySQL database. Additionally both users have existed for some time and the databases are in sync. Customers also do not have any access to the file system so there will be no symlinks in place. Its also not a single server that we are seeing the issue on, it maybe one Dovecot server accessing one NFS server. Then the next time its a different Dovecot server accessing a different NFS server. >> >the logs for that time which is abnormal (a whole bunch of other logins from >> >other customers but nothing from those two users and no errors) > What about cron jobs, message delivery, backups, ... anything that > possibly can alter that file. I don't think, it's a Dovecot issue, unless > the uid 26624 is valid and hamish is shared with that user. Nothing besides Courier being replaced by Dovecot has changed in the server setup (although I could be wrong there, but we are going through one component at a time and until this issue is resolved we are not moving onto the next), and the only file which is being modified is a file which only Dovecot maintains. There are hourly backups which do an rsync to another server in case of hardware failure, there are scripts which move mailboxes between NFS servers but they show up in logs. Exim has no need to touch a dovecot controlled file, and when it writes mail into the maildir its writing as the correct user. It also seem odd that one login is fine then randomly the next login the file ownership has changed, nothing happens in between the two logins which are in some cases only 5 to 10 minutes apart. All I am really looking for is ideas on where to look, as it seems odd that nobody else is reporting this, and since its a reasonably new setup its possibly something we have done in the config (which I posted in my first email). Is there a reliable way to run a script directly when a dovecot session starts and finishes so we could output the ownership before and after which may also help eliminate the session itself. Cheers, Bruce

[Dovecot] empty emails with 2.2.13/pigeonhole
by Cor Bosman 04 Jun '14

04 Jun '14

I recently upgraded from 2.2.10 to 2.2.13, and also upgraded pigeonhole. Ever since im seeing some empty emails appear in my inbox. Return-Path: <cricket(a)stats2.xs4all.net> Delivered-To: <cor> Received: from imapdirector1.xs4all.net ([194.109.26.173]) by userimap9.xs4all.nl (Dovecot) with LMTP id CHu0MUDDjlOBdwAAwvsqNQ for <cor>; Wed, 04 Jun 2014 08:57:04 +0200 Thats all this mail contains. This only happens using LMTP/Sieve, and with many different senders/recipients. Debug log shows nothing out of the ordinary, except that the mail seems to be corrupted by the time it hits sieve. It's very hard to diagnose. Our path is kind of lengthy, and in theory it could happen everywhere. Mail first arrives on incoming MX server which is sendmail. From there it's sent to a dovecot director using lmtp, which sends it to a server that does final delivery with sieve. Im not sure where the email gets corrupted. Any extra debugging I could turn on? Two extra things to note. So far it seems to only happen to emails that would have hit a matching sieve filter rule. I have asked a dozen people to verify this, and all emails would have matched a filter if all was well. Instead, it gets dropped into the inbox because pigeonhole seems to be working with the corrupt file and cant match any rules anymore. And second, 99% of our email is handled differently, from the sendmail server directly into a local mailer, and that never causes issues. We're in the process of switching to lmtp. Any insights? cor

[Dovecot] /etc/passwd userdb and long usernames
by Nicolás Reynolds 04 Jun '14

04 Jun '14

hi! i've configured dovecot to lookup usernames in /etc/passwd and it's working ok but it's having some problems retrieving info when the username is longer than 32 chars (i know it isn't recommended but everything seemed to work ok except for the hardcoded limit in useradd...) i found this on logs showing extra characters on the home field: http://pastie.org/pastes/9257902/text?key=vsxstofu3rf5wum4aic5va is there a limit on username length? i "solved" it by setting auth_username_format = %0.30u -- http://partidopirata.com.ar

[Dovecot] Dovecot + NFS + FreeBSD breakage ?

[Dovecot] Change in LAYOUT=fs between 1.2.9 and 2.0.19?
by Martijn 04 Jun '14

04 Jun '14

While testing an upgrade from Dovecot 1.2.9 (on Ubuntu 10.04 LTS) to 2.0.19 (12.04 LTS) I encountered the following change in behaviour: In both setups, mail_location is defined as follows: mail_location = maildir:~/domains/%d/%n/.Maildir:LAYOUT=fs No other mail_location-related settings are set in the config. On 1.2.9 this leads to new mail being delivered to this example directory: /home/username/domains/example-domain.ext/webmaster/.Maildir/INBOX/new/ On 2.0.19 the exact same mail_location is set, but new mail is now delivered to: /home/username/domains/example-domain.ext/webmaster/.Maildir/new/ Notice the missing /INBOX/ in the path on 2.0.19. I found no mention of this change on http://wiki2.dovecot.org/Upgrading/2.0 which first lead me to suspect this was a bug in 2.0.19. However, while browsing the 2.0-wiki I found a page which sheds some light on the behaviour that is to be expected from Dovecot 2.0.x. Quote from http://wiki2.dovecot.org/MailLocation/Maildir#Directory_layout > "Mailbox directory name": "Without DIRNAME, INBOX will be stored at ~/Maildir/{new,cur,tmp}/, but when DIRNAME is specified, we get an extra path component INBOX/ immediately prior to the DIRNAME value, so in the example above INBOX would be stored at ~/Maildir/INBOX/mAildir/{new,cur,tmp}/." I then changed mail_location to have an empty DIRNAME, like: mail_location = maildir:~/domains/%d/%n/.Maildir:LAYOUT=fs:DIRNAME= It appears this fixes the problem for new mail arriving (haven't tested other folders yet). Questions: 1. Is this a deliberate change in behaviour between the two versions? If so, may I suggest adding this change to the Upgrading to 2.0 wiki page, because I was unable to find the relevant info quickly. If not, is this a misconfiguration on my side, or a (known) bug in one of the two versions? 2. Is the DIRNAME=(empty) a good solution, or is it unusual/hacky to leave DIRNAME empty? Any particular problems I may expect using this configuration? Thanks in advance for your help. -- Kind regards, Martijn

[Dovecot] Info about sharing mail folder
by Gianluca Calloni 03 Jun '14

03 Jun '14

Hi to all. First of all.. I'm new on the mailing list.. So.. Sorry in advance for any mistake or error on posting here.. The question (or doubt..) is about sharing mail folder. I use a test mail server. Is not the production server (always dovecot + postfix + spamassassin + clamav) Well.. In test mail server i can use the share folder, follow the conf istruction on wiki dovecot. And work fine. But i need to know if is possible for user_a(a)mydomain.com to share only 1 or 2 subfolder (E.g. .INBOX.FOLDER_A and .INBOX.FOLDER_B shared, .INBOX_FOLDER_C not shared) When i do some test sharing folder, the user with wich user_a(a)mydomain.com share the mailbox can view all the subfolder of user_a(a)mydomain.com Following my dovecot versione e config. Thank's in advance My dovecot version is 2.0.19 My dovecot conf is : # 2.0.19: /etc/dovecot/dovecot.conf doveconf: Fatal: open(/etc/dovecot/dovecot.conf) failed: Permission denied calloni@dovecot:~$ sudo -i [sudo] password for calloni: root@dovecot:~# dovecot -n # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.5.0-49-generic i686 Ubuntu 12.04.4 LTS ext4 dict { acl = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no first_valid_uid = 150 last_valid_uid = 150 mail_gid = mail mail_location = maildir:/var/vmail/%d/%u mail_plugins = acl mail_uid = vmail namespace { inbox = yes location = prefix = separator = / type = private } namespace { list = yes location = maildir:%%h:INDEX=~/shared/%%u prefix = shared/%%u/ separator = / subscriptions = no type = shared } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { acl = vfile acl_shared_dict = proxy::acl } postmaster_address = postmaster(a)jodovit.local protocols = " imap pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = mail mode = 0600 user = vmail } } service dict { unix_listener dict { group = mail mode = 0600 user = vmail } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } Thi

Not offhand, but if you want a remote tool, it ought to be simple to cobble together some feeder script and netcat (or openssl s_client). It will also be simpler if you configure the master password feature so you don't have access to all user passwords. So something like this for dumping the INBOX contents #!/bin/sh master-user=masteru master-password=masterp while read user server; do netcat --ssl $server 993 <<_EOF_ >${user}.report 1 LOGIN ${user}*${master-user} ${master-password) 2 SELECT INBOX 3 ... 4 LOGOUT _EOF_ done I don't know enough IMAP to fill in "3 ..." to dump all headers, but I'm sure it's not hard to find out. It's even simpler if you don't need to do it remotely: just use doveadm fetch -A hdr MAILBOX '*' Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] list all emails from command line?
by Tomasz Chmielewski 03 Jun '14

03 Jun '14

This is not strictly Dovecot question, but a more general IMAP one. I'm running a Dovecot server and have a user who is claiming that some email sent to him, say, on 30 May, showed up in his mailbox on 02 Jun. I've checked Postfix logs, and the message was correctly received on 30 May and passed to Dovecot. A similar issue happens every few days. This leaves me with two possibilities: 1) Dovecot is somehow not presenting the new mail to the user in a "timely manner" 2) user's email program is broken Therefore, I wanted to do some kind of "IMAP list" of the account, with a command line tool: - specify username, pass and server, - the tool would return a list of all email in their folders (message ID, From, To, Date, Subject). I would run it i.e. daily and this would let me verify when the mail was really visible in the account. Is anyone aware of a tool I could use to achieve that? -- Tomasz Chmielewski http://www.sslrack.com

Hello everyone, I have a small problem with dovecot installed on ubuntu-13.10. I use dovcot as LDA with a LDAP-passdb and a pam-passdb. The userdb is static. A mail to LDAP-user 'foo' is delivered with the error-message dovecot: lda(foo): Error: User foo doesn't have home dir set, disabling duplicate database A mail to the pam-user 'bar' will deliverd without this error. But both users should work with the static-userdb. Where is my mistake?

[Dovecot] Dovecot 2 | Creating message rules
by Jos Chrispijn 02 Jun '14

02 Jun '14

Can someone explain how I can create message rules to use with this version of Dovecot? I specially switched to this version because it supports then Pigeonhole Sieve. I would like to volunteer to contribute as a volunteer when someone would like to create a html driven user interface that provides a user friendly configuration interface and would make such configuration a piece of cake. -- Best regards, Jos Chrispijn --- Artificial intelligence is no match for natural stupidity

[Dovecot] Dovecot 2.1.13: some questions about the mail-filter plugin
by Axel Luttgens 02 Jun '14

02 Jun '14

Looking at mail_filter_mailbox_allocated() of src/plugins/mail-filter/mail-filter-plugin.c: if ((class_flags & MAIL_STORAGE_CLASS_FLAG_OPEN_STREAMS) == 0 && (class_flags & MAIL_STORAGE_CLASS_FLAG_BINARY_DATA) != 0 && muser->out_socket_path != NULL) v->save_begin = mail_filter_mail_save_begin; it seems that a backend with MAIL_STORAGE_CLASS_FLAG_OPEN_STREAMS unset and MAIL_STORAGE_CLASS_FLAG_BINARY_DATA set is expected by the plugin. Technically, this would thus exclude the mbox backend, since its flag configuration seems to be exactly the opposite: struct mail_storage mbox_storage = { .name = MBOX_STORAGE_NAME, .class_flags = MAIL_STORAGE_CLASS_FLAG_MAILBOX_IS_FILE | MAIL_STORAGE_CLASS_FLAG_OPEN_STREAMS | MAIL_STORAGE_CLASS_FLAG_HAVE_MAIL_GUIDS, [...] Is this a correct interpretation? If yes, what is the rationale? I couldn't find any info related to such a limitation in the docs; the README file of http://dovecot.org/patches/2.2/mail-filter.tar.gz even says: "Mail filter plugin can read an email from any storage supported by Dovecot and modify the mail in some way"... All of this stems from my attempts to have working mail filters when I was trying to better understand the behaviors Stanislas was describing in a recent thread... Hence another question; in sdbox-storage.c, the definition of the "alias" for sdbox comes with: struct mail_storage dbox_storage = { .name = "dbox", /* alias */ .class_flags = MAIL_STORAGE_CLASS_FLAG_FILE_PER_MSG, [...] The initialization of member class_flags seems to be incomplete, when compared to the one for the name "sdbox". A typo? On the other hand, Stanislas showed a configuration with mail_location = dbox:/mailboxes/%Ld/%Ln and seemed to have a working mail filter. If above interpretation is correct, this would mean that the "alias" definition isn't used, but that the one for "sdbox" is used instead. Out of curiosity, how/where is that substitution achieved? Regards, Axel

[Dovecot] Combining userdbs
by Bubreg István 01 Jun '14

01 Jun '14

Hi, I think that using more than one userdb with setting the result actions doesn't work as expected from the documentation. The goal would be to set user-specific quotas for a few users with a specific passwd-file like this : cat /etc/dovecot/quotas foo:x::::::userdb_quota_rule=*:storage=2G The first userdb is passwd (with pam passwd): userdb { driver = passwd result_failure = return-fail result_internalfail = return-fail result_success = continue-ok skip = never } The second one is for the specific quota userdb { args = username_format=%n /etc/dovecot/quotas driver = passwd-file result_failure = continue result_internalfail = continue result_success = return-ok skip = notfound } User 'foo' exists in (pam) passd, but there's no place to store his own quota rule, that's why came handy to use a second userdb for storing just one extra field. That's working quiet well, he default quota is overriding form passwd-file. BUT: I've played a lot with changing the result_* and the 'skip' parameters, but none of them worked in the situation where a user ('bar') _only_ exists in passwd (and has to use the default quota config). doveadm quota get -u bar says doveadm(bar): Fatal: User doesn't exist With changing the parameters this error has gone, but the second userdb doesn't used for user 'foo' - even if the parameters are : userdb { driver = passwd result_failure = return-fail result_internalfail = return-fail result_success = continue <-- in theory, the next userdb is coming skip = never } userdb { args = username_format=%n /etc/dovecot/quotas driver = passwd-file result_failure = continue result_internalfail = continue result_success = return-ok skip = notfound } My question is that how should i set the result_* and 'skip' parameters to solve this : - there's a default quota rule in the config - some (a few) users has a larger quota - there's no way to store the user-specific quotas in the 'real' userdb (because it's pam/passwd) Thank you for your effort. # dovecot -n # 2.2.13 (de9b10f2e168): /etc/dovecot/dovecot.conf # OS: Linux 3.11.0-15-generic i686 Ubuntu 12.04.4 LTS auth_debug = yes auth_debug_passwords = yes auth_verbose = yes auth_verbose_passwords = yes disable_plaintext_auth = no listen = * log_path = /var/log/dovecot.log mail_debug = yes mail_location = maildir:~/Maildir mail_plugins = " quota" 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 ihave duplicate namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } plugin { quota = maildir:User quota quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap sieve" service managesieve-login { inet_listener sieve { port = 4190 } } service managesieve { process_limit = 1024 } ssl = no ssl_cert = </etc/dovecot/private/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = passwd result_failure = return-fail result_internalfail = return-fail result_success = continue-ok } userdb { args = username_format=%n /etc/dovecot/quotas driver = passwd-file result_failure = continue-ok result_internalfail = continue-ok skip = notfound } protocol imap { mail_plugins = quota }

[Dovecot] Disabling plus sign extension delimiter in lmtp listener (or userdb)
by Benoit Panizzon 01 Jun '14

01 Jun '14

Hello We have migrated our email services from a server, which did not support IMAP and folders, therefore threated the plus sign + as a normal character in a part of an email address. Our new server delivers the emails via lmtp to dovecot. the few users which got a + character in the username first could not log-in (fixed by adding + to auth_username_chars). Now the next problem turn out to be, that the lmtp listener stripps everything after the + sign. The MTA correctly sends the whole email address, so it's not the MTA's fault. It can easily be tested by connecting to the dovecot LMTP listener IP address by telnet: 220 grautvornix.imp.ch Dovecot ready. mail from:<nobody> 250 2.1.0 OK rcpt to:<b+enoit(a)iscan.ch> 550 5.1.1 <b+enoit(a)iscan.ch> User doesn't exist: b(a)iscan.ch I could not find any configuration parameters for the lmtp listener or userdb service to tell it what to do with the + sign. Did I miss something, or is it impossible to have the + sign accepted as a normal character in an email address? Kind regards -Benoit-

[Dovecot] Upgraded my dovecot?
by Knute Johnson 31 May '14

I upgraded my server from Ubuntu 12.04LTS to 14.04LTS and it upgrade my dovecot too. Probably should have thought about that a little more before I pushed the button but oh well. So it didn't work when it came back up and I had to add a "inbox=yes" line to my namespace in 15-mailboxes.conf and that fixed it. So is there anything else I should update in my config files for this newer version of dovecot? # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-30-generic x86_64 Ubuntu 14.04 LTS auth_mechanisms = plain login mail_location = mbox:~/mail:INBOX=/var/mail/%u namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = " imap" service imap-login { inet_listener imaps { port = 0 } } service pop3-login { inet_listener pop3 { port = 0 } inet_listener pop3s { port = 0 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { imap_capability = IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS mail_max_userip_connections = 30 } Thanks,

[Dovecot] ot: identifying TB IMAP issues
by voytek＠sbt.net.au 31 May '14

31 May '14

I have a user with with W7/TBird/IMAP to my dovecot 2.1.17 server, the user complains whilst he is composing lengthy emails (with multiple fowrds/replies quoted in the message) he gets 'hour glass' over compose windows with some message about not being able to save drafts, he then powers off ADSL modem, which enables him to continue composing email, powers on ADSL, and sends email what if anything can I assess at server end to identify any issues? any TB tips, what to enable or disable on TB ? looking at dovecot now (past the issue) with 'doveadm who' I don't see the user listed I think the user keeps many messages open concurrently in TB tabs, could that exhaust connection limit ? I expect this to be a TB issue? but, hope for some pointers

Hi there, We recently upgraded to 2.2.12 (the current version in FreeBSD's port tree), and are seeing these errors in our logs (not super frequently, but it happens): May 30 13:20:57 mail1 kernel: pid 15752 (imap), uid 1005: exited on signal 6 May 30 13:20:57 mail1 dovecot: imap(xxx): Fatal: master: service(imap): child 15752 killed with signal 6 (core not dumped - set service imap { drop_priv_before_exec=yes }) I tried manually upgrading to 2.2.13, on the off chance that was fixed, but I couldn't get the new pigeonhole (0.4.3) to compile once I did (perhaps why the FreeBSD port maintainer hasn't updated yet?). Suggestions? Right now we just check every couple of hours for affected users, and then delete all of the dovecot files for the affected user, which ends the error. Thanks, Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---

As others have intimated, the use of procmail as your LDA is causing your mailbox to become inconsistent with respect to your indices. Procmail is appending your messages to mailboxes, but is ignorant of the existence of dovecot indices, and does not update them. When your IMAP service access those mailboxes, it detects this condition, and that's the log messages you are seeing. I think those messages are benign -- you can probably ignore it. Dovecot will automatically rebuild them. The alternative is to let dovecot's be responsible for message delivery: it can then update the indices, and IMAP/POP will find consistent indices.
