[Dovecot] Dovecot-2.1.14 - pop3 processes always hangs forever - another follow-up
by Axel Luttgens 19 Feb '13

19 Feb '13

Hello, With the same basic configs as in my previous messages, I tried with the maildir format instead of the mbox format. That is, in both cases ("virtual" uids/gids vs a single "real" uid/gid), doveconf -n shows: mail_location = maildir:~/maildir instead of: mail_location = mbox:~/mboxes:INBOX=~/mboxes/inbox Here too, with "virtual" uids/gids, connections thru pop hang forever, while imap connections behave flawlessly. And with a single "real" uid/gid, connections thru both pop and imap behave as expected. As a result, it could be inferred that the problems I am encountering with pop connections do not depend on the mailbox format in use, and that they are entirely related to "virtual" uids/gids. To recap: with this very basic config # 2.1.14: /_ETC/dovecot/dovecot.conf # OS: Darwin 12.2.1 x86_64 auth_verbose = yes disable_plaintext_auth = no mail_debug = yes mail_location = mbox:~/mboxes:INBOX=~/mboxes/inbox passdb { args = /_ETC/dovecot/db.conf driver = sql } ssl = no userdb { driver = prefetch } a pop connection hangs forever after the pass command $ telnet 127.0.0.1 110 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Dovecot ready. user user2 +OK pass pass2 and the log shows (here, when the user connects for the first time) dovecot[2997]: pop3-login: Login: user=<user2>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=3113, secured, session=<GTOlMjfV3gB/AAAB> dovecot[2997]: pop3(user2): Debug: Effective uid=100003, gid=100003, home=/_Data/Mailstores/100003 dovecot[2997]: pop3(user2): Debug: Home dir not found: /_Data/Mailstores/100003 dovecot[2997]: pop3(user2): Debug: fs: root=/_Data/Mailstores/100003/mboxes, index=, control=, inbox=/_Data/Mailstores/100003/mboxes/inbox, alt= dovecot[2997]: pop3(user2): Debug: Namespace : /_Data/Mailstores/100003/mboxes doesn't exist yet, using default permissions dovecot[2997]: pop3(user2): Debug: Namespace : Using permissions from /_Data/Mailstores/100003/mboxes: mode=0700 gid=-1 dovecot[2997]: pop3(user2): Debug: Namespace : /_Data/Mailstores/100003/mboxes/inbox doesn't exist yet, using default permissions dovecot[2997]: pop3(user2): Debug: Namespace : Using permissions from /_Data/Mailstores/100003/mboxes: mode=0700 gid=-1 dovecot[2997]: pop3(user2): Debug: Namespace : /_Data/Mailstores/100003/mboxes/inbox doesn't exist yet, using default permissions dovecot[2997]: pop3(user2): Debug: Namespace : Using permissions from /_Data/Mailstores/100003/mboxes: mode=0700 gid=-1 With exactly the same config, imap connections are fully functional. Does someone have an explanation? TIA, Axel

[Dovecot] Defer emails until the user is ready to deal with them (snooze button / bring-forward file / bring-up file for emails)
by Chris Laif 19 Feb '13

19 Feb '13

Hi, I would like to add a feature to my email-client (Thunderbird) which stops emails from showing up until a specific time (e.g. having buttons for: show again this evening, tomorrow, next week, next month ...). As far as I've learned this is not possible with IMAP: - storing the 'do-not-show-until-time' within a custom header-field requires down- and uploading of the whole email and therefore causes problems especially with large emails - IMAP keywords are limited are limited in quantity and can not be compared with datetime functions Any suggestions will be greatly appreciated! Chris

[Dovecot] Get rid of inotify in 2.1.15
by Martin Rabl 19 Feb '13

19 Feb '13

Hi, after update to Dovecot 2.1.5 (Ubuntu 12.04, dovecot from https://launchpad.net/~kokelnet/+archive/dovecot21) we are getting a huge ;-) bunch of log entries about " imap(USERNAME): Warning: Inotify instance limit for user 5000 (UID vmail)". At last I did an echo 512 > /proc/sys/fs/inotify/max_user_instances but the logentries did appear again after some minutes. Maybe you have a hint for me? Thank you! At the bottom my current configuration. -- Greetings, Martin Rabl # 2.1.15: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-36-generic x86_64 Ubuntu 12.04.2 LTS auth_anonymous_username = anonymous

[Dovecot] statistics on proxy ???
by Marco Giunta 19 Feb '13

19 Feb '13

Hi at all, could I have imap statistics on my dovecot proxy server ?? Here my config: # 2.1.13: /etc/dovecot/dovecot.conf ... mail_plugins = stats ... plugin { ... stats_refresh = 30 secs stats_track_cmds = yes } ... service stats { fifo_listener stats-mail { mode = 0666 } } ... protocol imap { ... mail_plugins = stats imap_stats } File '/var/run/dovecot/stats' is always 0 byte: # ls -la /var/run/dovecot/stats srw-------. 1 root root 0 Feb 18 14:24 /var/run/dovecot/stats and 'dovecotadm' say always: # doveadm stats dump session doveadm(root): Info: no statistics available Is there something wrong in my config, or stats are not available on proxy ??? Cheers, Marco

[Dovecot] Private message flags in shared mailboxes
by Timo Sirainen 19 Feb '13

19 Feb '13

I'm wondering a bit how these should work. Comments welcome. In v2.2 the recommended way to enable private flags for shared mailboxes is to create private indexes with :INDEXPVT=<path>. This creates dovecot.index.pvt[.log] files which only contain message UIDs and flags. The indexes are updated somewhat lazily by updating them whenever user has the shared mailbox opened and it gets synced. 1. What would be a good place to configure which flags are shared and which are private? Currently it forces \Seen flag to be private and others not. With Maildir I used to have the idea of configuring these in dovecot-shared file, but that's a rather annoying extra file. Then again it could be cached into dovecot.index. Another possibility would be in dovecot-acl file, but public mailboxes might be enabled without ACL plugin. Mailbox attributes (for URLAUTH and for future METADATA) also exist in v2.2, but they require configuring a dict for them, which isn't very efficient either to read every time a mailbox is accessed. Mailbox's admin user should be able to do this somehow via IMAP protocol also. METADATA would pretty much be required for that I guess. 2. Private flags aren't currently inherited from the primary (shared) flags. With user-shared mailboxes this is good, because the owner doesn't have private indexes for the mailboxes, so when owner reads a mail it gets a \Seen flag in the primary index. If that mailbox was shared to someone else, the \Seen flag shouldn't be set. But this also means that for truly shared (public) mailboxes that have no owner you can't set initial flags with Sieve's addflag command (e.g. \Seen flag to high-scored mails in Spam). I guess it could be possible to change this so that the inheritance is done for public namespaces but not for shared namespaces, but is that really a good idea either?.. 3. Currently COPY/APPEND ignore any private flags (which also means dsync won't set them always). Fixing this would require remembering these flags, committing the save to primary index, syncing the private index to get the new mails added there, then updating their flags (or doing it directly at sync stage with some kludging code). To avoid race conditions the private index would need to be locked before committing the save. I guess this is doable.. 4. Private keywords aren't supported. I guess not much worse than system flags, but more code complexity. Wonder if anyone would care about them.

[Dovecot] Requested xxxx scheme, but we have a NULL password after upgrade
by PhilQ 14 Feb '13

14 Feb '13

I'm having an issue I can't seem to work around after upgrading from Dovecot 1.0.7 to 1.2.17. After getting Dovecot 1.07 working on CentOS 5.9, I decided that it might be wise to upgrade to a later version, so I stuck with 1.x and went with 1.2.17, which I had to compile from source. CentOS was originally using /etc as the starting path for Dovecot files but the source distribution puts most of the stuff under /usr/local/etc. After the usual config>make>make install dance I made the necessary changes to point to the new libraries, modules, etc. and the "imap-login: Fatal: Dovecot version mismatch: Master is v1.2.17, login is v1.0.7...." messages went away. After doing this though I cannot login, I get the following error messages: Feb 13 15:50:40 auth(default): Info: client in: AUTH 7 NTLM service=imap lip=192.168.2.102 rip=192.168.2.100 lport=143 rport=1470 Feb 13 15:50:40 auth(default): Info: client out: CONT 7 Feb 13 15:50:40 auth(default): Info: client in: CONT 7 TlRMTVNTUAABAAAAB4IIogAAAAAAAAAAAAAAAAAAAAAFASgKAAAADw== Feb 13 15:50:40 auth(default): Info: client out: CONT 7 TlRMTVNTUAACAAAAMAAwADAAAAAFAooATj7XW6ve2hwAAAAAAAAAADgAOABgAAAAUwBlAHIAdgBlAHIAMQAuAGgAZQByAHMAYwBoAGwAYQB1AHIAZQBuAC4AYwBvAG0AAwAwAFMAZQByAHYAZQByADEALgBoAGUAcgBzAGMAaABsAGEAdQByAGUAbgAuAGMAbwBtAAAAAAA= Feb 13 15:50:40 auth(default): Info: client in: CONT 7 TlRMTVNTUAADAAAAGAAYAGoAAABoAGgAggAAAAAAAABIAAAAEAAQAEgAAAASABIAWAAAAAAAAADqAAAABQKIAgUBKAoAAAAP*CENSORED*bgBiAFEAUwBFAC0AVwBJAE4AWABQAEXO6p/WuopqQ02x1kzJGW3NoQELKw32N88JqkbMOYOVErhiS492elwBAQAAAAAAA*CENSORED*ysN9jcAAAAAAwAwAFMAZQByAHYAZQByADEALgBoAGUAcgBzAGMAaABsAGEAdQByAGUAbgAuAGMAbwBtAAAAAAAAAAAA Feb 13 15:50:40 auth(default): Info: cache(pquesinb,192.168.2.100): miss Feb 13 15:50:40 auth(default): Info: passwd-file(pquesinb,192.168.2.100): lookup: user=pquesinb file=/etc/dovecot.users Feb 13 15:50:40 auth(default): Info: password(pquesinb,192.168.2.100): Requested NTLM scheme, but we have a NULL password Feb 13 15:50:40 auth(default): Info: cache(pquesinb,192.168.2.100): miss Feb 13 15:50:40 auth(default): Info: password(pquesinb,192.168.2.100): passdb doesn't support credential lookups Feb 13 15:50:40 auth(default): Info: cache(pquesinb,192.168.2.100): miss Feb 13 15:50:40 auth(default): Info: password(pquesinb,192.168.2.100): passdb doesn't support credential lookups Feb 13 15:50:40 auth(default): Info: cache(pquesinb,192.168.2.100): miss Feb 13 15:50:40 auth(default): Info: password(pquesinb,192.168.2.100): passdb doesn't support credential lookups Feb 13 15:50:40 auth(default): Info: cache(pquesinb,192.168.2.100): miss Feb 13 15:50:40 auth(default): Info: password(pquesinb,192.168.2.100): passdb doesn't support credential lookups Feb 13 15:50:42 auth(default): Info: client out: FAIL 7 user=pquesinb Looking at the log from the old version while it was working, I was getting messages like the following: dovecot: Feb 04 14:14:21 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 04 14:14:21 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 04 14:15:03 Info: IMAP(pquesinb): Disconnected: Logged out dovecot: Feb 04 14:15:03 Info: IMAP(pquesinb): Disconnected: Logged out dovecot: Feb 04 14:15:23 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 04 14:15:23 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 04 14:16:05 Info: IMAP(pquesinb): Disconnected: Logged out dovecot: Feb 04 14:16:05 Info: IMAP(pquesinb): Disconnected: Logged out /etc/dovecot.users contains a list of usernames. Is this error the result of additional security which has been incorporated into the later version of Dovecot, or is it because my installation of the later version from source is broken, somehow incompatible, etc? Dovecot was configured to use PAM and it appeared to know the password of my account, failing when it was entered incorrectly so I'm assuming that it was successfully using PAM. I kept the same syntax in the later config file. >From dovecot.conf: passdb pam { # [session=yes] [setcred=yes] [failure_show_msg=yes] [max_requests=<n>] # [cache_key=<key>] [<service name>] # # session=yes makes Dovecot open and immediately close PAM session. Some # PAM plugins need this to work, such as pam_mkhomedir. # # setcred=yes makes Dovecot establish PAM credentials if some PAM plugins # need that. They aren't ever deleted though, so this isn't enabled by # default. # # max_requests specifies how many PAM lookups to do in one process before # recreating the process. The default is 100, because many PAM plugins # leak memory. # # cache_key can be used to enable authentication caching for PAM # (auth_cache_size also needs to be set). It isn't enabled by default # because PAM modules can do all kinds of checks besides checking password, # such as checking IP address. Dovecot can't know about these checks # without some help. cache_key is simply a list of variables (see # doc/wiki/Variables.txt) which must match for the cached data to be used. # Here are some examples: # %u - Username must match. Probably sufficient for most uses. # %u%r - Username and remote IP address must match. # %u%s - Username and service (ie. IMAP, POP3) must match. # # The service name can contain variables, for example %Ls expands to # pop3 or imap. # # Some examples: # args = session=yes %Ls args = cache_key=%u dovecot #args = dovecot } If anyone could give me some ideas on where to go from here, I'd really appreciate it. If there's little chance of getting the newer version to work with CentOS 5 then I'm ready to just drop back to the older version.

Re: [Dovecot] Authentication with many Windows AD

Hi, > You can set as many databases as you want. Check this: > > http://wiki2.dovecot.org/PasswordDatabase > http://wiki2.dovecot.org/Authentication/MultipleDatabases This solution is valid if I have only one domain. In case you have more than one domain, you need authenticate in the appropriate LDAP server. Is That correct? I'm going to explain my particular case. I have five Windows domains with some users who belong to those domains. I also have other users who are authenticated with local UNIX accounts. The only thing that I can do (I think) is using a Radius server. But, I'd rather not use it.

I use Dovecot 2.0.9 and Postfix 2.6.6 on host x86_64-redhat-linux-gnu 2.6.32-279.14.1.el6.x86_64 CentOS release 6.3 (Final) I need to select the validation method depending on the user. I have users that have to be authenticate with UNIX account, and I have others thats have to be authenticate with Windows AD. For example, some sysadmins and special accounts needs validate with Unix accounts. Other normal users have to authenticate with Windows AD, I have many Windows controllers. Some users authenticate to a specific Windows AD and other users are validated in another one. How I can do this? Thank you very much. Antonio Alberola

[Dovecot] FreeBSD, Dovecot and ZFS
by Jason Lock 13 Feb '13

13 Feb '13

Mail Issues - FreeBSD Hello, my apologies if this may be the wrong forum but hoping that maybe someone might be able to provide some insight. Have a very sporadic and strange issue with our mail servers running Dovecot on FreeBSD. There are three servers hosting Dovecot with FreeBSD as the underlying operating system. All three connect to a NAS server, again running FreeBSD and ZFS. When the specific issue occurs, clients connecting to check mail via POP3 or IMAP experience long delays and timeouts. To the point where POP3 Logins fail due to the timeouts. The issue is further compounded by clients increasing the number of attempts to check mail. Part of the frustration in attempting to diagnose the issue is not knowing the root cause or symptom that initates the issue. Wondering if anyone has experienced anything similar, or suggestions on ways to help identify the root cause

[Dovecot] backing up maildir dovecot files
by David Mehler 13 Feb '13

13 Feb '13

Hello, I'm having to migrate servers. Both are dovecot2 systems. I'm wanting to copy over my mail store from one system to the other. I'd like to preserve dates/times of emails. These are maildir setups on both boxes, I'd like to be as transparent to the end user as possible. I currently have the first dovecot system offline and the second dovecot system is offline. Recommendations? Thanks. Dave.

[Dovecot] dsync 2.1.10 does not correctly handle renames of mailbox subtrees
by Karol Jurak 13 Feb '13

13 Feb '13

Hi, It seems that dsync 2.1.10 does not correctly handle renames of mailbox subtrees. The scenario is as follows. There are two servers, A and B, both running dovecot 2.1.10 and configured to use mdbox. Automatic replication between them is disabled, ie. replication plugin is not active and replicator service has process_min_avail = 0. I perform the following actions: 1. On A: doveadm mailbox create -u test_user a a/b a/b/c d 2. On A: doveadm sync -u test_user -d The result is as expected: on both A and B there are a/b/c and d mailboxes. Now I connect to A via IMAP and rename a/b to d/b. The result is as expected: on A there are a and d/b/c mailboxes. Next I execute on A 'doveadm sync -u mailstoragetest -d' and now the result is not as expected: there are a/b/c and d/b subtrees on both A and B and a/b is just a directory, ie. it does not contain dbox-Mails (the rest are proper mailboxes). dovecot.mailbox.logs have the following records appended to them: A: #2112: rename 33259783092361d18c60ba1c7cfe973c (2013-02-12 10:42:55) - this probably is the rename of a/b to d/b (recursive, ie. including children - in this case a/b/c => d/b/c) by the IMAP client #2136: rename ee2be6da91ae879476b152d7ca041f1b (1970-01-01 01:00:00) - rename of d/b/c to a/b/c by dsync (unexpected/incorrect) B: #1104: rename 33259783092361d18c60ba1c7cfe973c (1970-01-01 01:00:00) - rename of a/b to d/b (non recursive) by dsync What seems to be missing is the record in A's dovecot.mailbox.log describing the rename of a/b/c to d/b/c (or in general case the set of records describing the renames of all the children of a/b). Would appending such records allow dsync to make correct decisions as to which mailboxes and on which servers to rename?

What namespace config do you have? I got more info from the user that had this problem. He reported that he was was setting up a new Email client (Nexus4 Android) and he sent me a screenshot of his setup. Everything look ordinary except perhaps the IMAP prefix set to "mail". My setup documents inform users to leave it blank, but sometimes they use "mail/", a holdover from the uw-imapd days. I provide some aliases for that, but I don't know what would happen if you leave off the trailing "/". My namespace settings as reported by dovecot -n: namespace { inbox = yes location = prefix = separator = / } (The following are aliases to keep backward compatibility) namespace { alias_for = hidden = yes list = no location = prefix = / separator = / } namespace { alias_for = hidden = yes list = no location = prefix = mail/ separator = / } namespace { alias_for = hidden = yes list = no location = prefix = ~/mail/ separator = / } namespace { alias_for = hidden = yes list = no location = prefix = ~%u/mail/ separator = / } I've asked the user to change his prefix, and he'll probably report back.

[Dovecot] Is there any way to mask or hide the INBOX label for Dovecot 1.2.x Shared Mailboxes?
by Jason Discount 13 Feb '13

13 Feb '13

Hello, I'm setting up a new Dovecot sever to replace an old Cyrus server, and need to keep things as consistent as possible. I have a couple local accounts, like junkmail and notjunkmail that users get shared access to, and can drop things in to train sa-update. However, when users share over junkmail's inbox, it's displayed in the hierarchy: • Other Users • junkmail • INBOX Is there any way to get junkmail's INBOX to just show up at Other Users/junkmail and not require that extra depth? • Other Users • junkmail I'm running Debian Squeeze and the standard dovecot package available therein: > # uname -a > Linux internet.digitalquay.com.au 2.6.32-5-xen-amd64 #1 SMP Sun Sep 23 13:49:30 UTC 2012 x86_64 GNU/Linux > #dovecot --version > 1.2.15 I'm running in a configuration where all mail is owned by the vmail user, due to the impression I'm under, that it's a better way if there is to be shared mailboxes.

[Dovecot] Marking messages read / retaining date with Sieve
by Bret Martin 13 Feb '13

13 Feb '13

I'm trying to mark several hundred thousand messages as read as they are delivered via dovecot-lda(1). (I'm importing some mail from another format for migration purposes.) I've been able to do this with Sieve, but it has the side effect that the messages' received and saved dates are set to the current date, and Apple Mail (at least) uses one of these to display the message date. Without the Sieve filter in place, the dates are retained based on the From_ line as I would like. Does anyone know of any way I can either - retain the date when delivering using Sieve? - systematically mark a specific set of messages as read *after* delivery instead, perhaps with doveadm(1)? (even marking *everything* read would work in this particular case. I couldn't find any way to set flags with doveadm) Thanks, --Bret

[Dovecot] POLL: v2.2 to allow one mail over quota?
by Timo Sirainen 12 Feb '13

12 Feb '13

Currently if user is 1MB under quota and someone tries to deliver mail that is over 1MB, Dovecot rejects the mail. But smaller mails aren't rejected probably for days. So user might not even realize that they didn't receive one of the mails. Also having a user "almost over quota" is a rather strange state I think. So what do you think about v2.2 allowing delivery of one last mail even if it brings the user over quota? Except add a limit that if the message size is as much as the user's entire quota limit it wouldn't be added (or 50% or ..?). Also IMAP wouldn't allow this, since user would get an error anyway. I could make this also optional, but if nobody really wants to keep the old behavior there's really no point in adding the option.

[Dovecot] Keyword Flags
by David Woodfall 11 Feb '13

11 Feb '13

I mostly use Mutt to read mail but today I fired up Thunderbird. I have a shell script that looks for new mail, which looks for files in cur/ and new/ ending with the server hostname or a comma. When I fired up TB it seems that all new mail has been given a flag of ,a which I gather means it matches a keyword. My questions are: How did this happen? Did TB do something strange to my mail when it fetched headers? If I change my search parameters to ',[a-z]' will this only catch new mail?

[Dovecot] Disabling auth caching just from one passdb
by Angel L. Mateo 11 Feb '13

11 Feb '13

Hello, I'm using various password databases (one of them is a ldap database, which is the used for users connecting with email clients, and the other with pam, using a pam module integrated with our SSO that is used from our webmail). I would like to disable password caching in my pam database (because 'passwords' provided by our SSO are single use tokens, so caching them has no benefit), but not in the ldap. As far as I know, auth_cache_size is the option to enable caching in all databases. But, is there any option I could use to disable it in a specific password database? -- Angel L.

[Dovecot] Moving index files on another disk: no troubles but need more assurances
by Paolo Miotto 11 Feb '13

11 Feb '13

Hi, I'm using dovecot 1.2.15 on debian squeeze with maildir, and I want to move index files out of the mailboxes disk to reduce disk I/O. I need to get the assurance that the switch is completely transparent to my clients (IMAP and POP). I read the wiki documentation and have found this thread (http://dovecot.org/pipermail/dovecot/2009-September/042665.html) which makes me confident, even if it speaks of a older version and only pop3. So I set up a test server, copied a true mailbox and changed mail location from: mail_location = maildir:~/Maildir to mail_location = maildir:~/Maildir:INDEX=/srv/indexes/%1n/%n (all users under the same domain, no need to use %d). On the IMAP side all seems to work fine, new indexes are created in the new location (dovecot.index.log on 1st access, dovecot.index.cache on message manipolation). A test client (evolution) doesn't notice at all, and I have verified via a telnet imap session that UIDs don't change. But I see that when I move the indexes the IMAP HIGHESTMODSEQ response changes and is reset to 1. Can this baffle the clients? On the rfc I don't found reference to this status walking backwards. Need I to verify that all messages have the virtual size (W=nnnn) in the file name (the mailboxes are from a previous cyrus installation, then we switch to dovecot 1.2)? What other test you suggest that checking UIDL on the pop3 side? What happens if the indexes disk disappears (broken or removed from bay or all paths down for FC/iscsi)? Can dovecot 1.2 continue with INDEX=MEMORY as for a disk full? Sorry for the many questions....

[Dovecot] dovecot, postfix and sieve - broken by Ubuntu upgrade 10.10 -> 12.04
by Johan Helsingius 10 Feb '13

10 Feb '13

Hi! In upgrading from Ubuntu 10.10 to 12.04, my mail setup (dovecot using sieve and postfix) broke pretty badly. Have gotten teh imap server working, but local delivery doesn't work. - sieve gets called, but all "fileto" actions result in "failed to store into mailbox 'zzz': Mailbox doesn't exist: zzz Dovecot version is 2.0.19, configuration is: # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-37-generic i686 Ubuntu 12.04.2 LTS ext4 auth_mechanisms = plain login base_dir = /var/run/dovecot/ disable_plaintext_auth = no info_log_path = /var/log/dovecot.info listen = * log_path = /var/log/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " login_greeting = Mail server ready. mail_location = maildir:/srv/mail/%u mail_max_userip_connections = 256 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 mbox_dotlock_change_timeout = 10 mins mbox_lock_timeout = 20 mins mbox_very_dirty_syncs = yes passdb { driver = pam } plugin { sieve = /home/julf/sieve } protocols = imap service auth { unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { mode = 0600 } user = root } service imap-login { chroot = login user = dovecot } service managesieve-login { chroot = login user = dovecot } service pop3-login { chroot = login user = dovecot } ssl = no userdb { driver = passwd }

[Dovecot] cPanel && Dovecot 2.x
by Marc Jauvin 10 Feb '13

10 Feb '13

I would like to know if dovecot 2.0.9+ can work with cPanel. I know there is a template for it in cPanel 11.34.1, but when I tried to switch to 2.0.9 (from 1.2.17), it didn't work. I didn't put too much time to test it since I only have one live system to test it with, and I have many customers hosted on this server and I cannot disrupt the service. Has anyone been able to make this work, and if so, is there anything special to do other than rebuilding the config with "/scripts/builddovecotconf" ? Thanks.

[Dovecot] GSS-SPNEGO with dovecot and Outlook without Samba
by Julian David Rath 10 Feb '13

10 Feb '13

I am trying to configure a dovecot2 IMAP server to inter-operate with a active directory to authenticate users. The users should be able to login without a password on a domain-joined client(Outlook). Is it possible to do this only with kerberos? I don't want to put a crappy winbind on my mailserver... I already configured my server to authenticate via kerberos(GSSAPI), but Outlook does not even try to authenticate using GSSAPI, it rather uses PLAIN. I would appreciate any help, many thanks in advance.

[Dovecot] dsync timeout?
by Micah Anderson 08 Feb '13

08 Feb '13

I'm using dsync for a regular backup. The backup system flocks so that two cannot run at the same time, which is generally a good thing. The problem is that it seems like dsync sometimes goes off into the weeds and never comes back, leaving a process running and doing nothing forever, hogging the lock and causing my backups never to run again. I just finally figured out that was what was causing the backups not to run on this system was this process: root 17836 0.0 0.0 40888 1600 ? S 2012 0:00 ssh -i /root/.ssh/backmaildir_id_rsa backmaildir@arg /usr/bin/dsync -u foobar server yeah, that has been running since 2012 :( root:/tmp# strace -p 17836 Process 17836 attached - interrupt to quit select(8, [4], [], NULL, NULL very exciting... There doesn't seem to be a timeout in dsync, but perhaps there should be? At this point my only option is to write a cronjob that will look for dsync processes that are over a certain amount of time old and then kill them, after I do that I will need to take a shower because that is a very dirty solution :P thanks for any ideas, or help! micah --

[Dovecot] Dovecot-2.1.14 - pop3 processes always hangs forever - a follow-up
by Axel Luttgens 08 Feb '13

08 Feb '13

Suspecting a problem with the "virtual" uids/gids, I've tried with a real user for the mail user: # 2.1.14: /_ETC/dovecot/dovecot.conf # OS: Darwin 12.2.1 x86_64 auth_verbose = yes disable_plaintext_auth = no mail_debug = yes mail_gid = dovemailer mail_location = mbox:~/mboxes:INBOX=~/mboxes/inbox mail_uid = dovemailer passdb { args = /_ETC/dovecot/db.conf driver = sql } ssl = no userdb { driver = prefetch } Of course, the db queries do not return uid/gid pairs anymore. And the pop3 processes now seem to work as expected; connecting for the first time as user1: $ telnet 127.0.0.1 110 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Dovecot ready. user user1 +OK pass pass1 +OK Logged in. list +OK 0 messages: . quit +OK Logging out. Connection closed by foreign host. Hmmm... Axel

[Dovecot] Dovecot-2.1.14 - pop3 processes always hangs forever
by Axel Luttgens 08 Feb '13

08 Feb '13

Hello, I'm currently experimenting with the 2.1.x series and am facing a behavior I can't explain; I must be doing something wrong and probably miss the obvious... ;-) This is a very basic build on Mac OS X 10.8.2: ./configure --prefix=/_COD/dovecot-2.1.14 --sysconfdir=/_ETC --localstatedir=/_VAR --with-sqlite --with-ldap=yes (Yes, I know, a strange layout, yet very convenient for testing various things here.) Dovecot's configuration is very basic too: # 2.1.14: /_ETC/dovecot/dovecot.conf # OS: Darwin 12.2.1 x86_64 auth_verbose = yes disable_plaintext_auth = no mail_debug = yes mail_location = mbox:~/mboxes:INBOX=~/mboxes/inbox passdb { args = /_ETC/dovecot/db.conf driver = sql } ssl = no userdb { driver = prefetch } It is started from launchd with the -F flag. Two users are defined in the database, user1 (100002/100002) and user2 (100003/100003), with "virtual" uids/gids. Connecting for the first time as user1 through imap: $ telnet 127.0.0.1 143 Trying 127.0.0.1... Connected to localhost.

But this is noticed by the master process: dovecot[2997]: pop3(user2): Fatal: master: service(pop3): child 3113 killed with signal 9 Note that it is possible to connect afterwards as user2 through imap. On the other hand, trying to connect as user1 or user2 through pop always hangs. TIA, Axel

[Dovecot] dsync: Invalid server handshake
by Dusan Zivadinovic 08 Feb '13

08 Feb '13

Hi list, I recently tried to backup mailboxes from an older server machine to a new one in order to move the service to the new machine. Both machines are in the same LAN, I used this command: dsync -R -u username backup ssh -i .ssh/id_rsa username(a)192.168.1.11 /opt/local/bin/dsync and I get this error: dsync-local(dz): Error: Invalid server handshake: dsync-server 2 dsync-remote(dz): Error: Invalid client handshake: dsync-client 1 # lokal machine: dovecot 2.0.19apple1 running on Mac OS X 10.8.2 Server using standard Apple-Dovecot-Configuration # remote machine: 2.1.12 running on Mac OS X 10.4 using PAM authentication I cant seem to find any documentation to this error, nor do I find any dsync entries in the logs of both machines. Does anyone have a hint? Thank you, Dusan

[Dovecot] File permissions used for automatically created mailbox
by Frerich Raabe 07 Feb '13

07 Feb '13

Hi, I'm running Dovecot 2.1.12 on FreeBSD (quite successfully so, thanks for this nice piece of software!). One thing which is slightly annoying though is that automatically created mailboxes (I have lda_mailbox_autocreate set) don't have the file permissions I'd like them to have. I'm using a vmail-based system, i.e. all mail is owned by vmail:vmail; another member of the vmail group is called 'backup', which has read access to all mail in order to create backups. All mail is stored beneath /home/vmail, e.g. /home/vmail/frerich/Maildir Right now, newly created mailbox directories (e.g. /home/vmail/bob) have 0700 permissions, but I'd like to have 0750 for all directories and 0640 for all files so that all files and directories are group-readable for backup purposes. Does anybody know whether this is configurable somehow? Right now, my workaround consists running this cron script every night: #!/bin/sh chown -R vmail:vmail /home/vmail/ find /home/vmail/ -type d -print0 | xargs -0 chmod 0750 find /home/vmail/ -type f -print0 | xargs -0 chmod 0640 -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing

[Dovecot] Sieve not filtering
by Nicolas Mora 06 Feb '13

06 Feb '13

Hello, I installed a few weeks ago the Dovecot package on a Debian stable along with postfix, everything works fine except the sieve filter. I followed the howto found on the internet (google: debian postfix dovecot sieve). I'm able to view and modify sieve rules with roundcube or thunderbird plugins, but the rules are not applied when a message arrives and all messages arrive in INBOX. Here is the content of my configuration files concerning sieve : dovecot.conf protocols = imap imaps managesieve protocol managesieve { listen = *:2000 } protocol managesieve { mail_executable = /usr/lib/dovecot/managesieve managesieve_max_line_length = 65536 managesieve_logout_format = bytes=%i/%o } protocol lda { postmaster_address = postmaster(a)babelouest.org mail_plugins = sieve mail_plugin_dir = /usr/lib/dovecot/modules/lda log_path = info_log_path = syslog_facility = mail } plugin { sieve_dir=~/Maildir/sieve } And the postfix/main.cf config file contains for dovecot sieve the following maibox_command = /usr/lib/dovecot/dovecot-lda -f "$SENDER" -a "$RECIPIENT" dovecot_destination_recipient_limit = 1 virtual_transport = dovecot I also tried the command mailbox_command = /usr/lib/dovecot/deliver it didn't work either... Is there somthing so obvious that I didn't see it ? Thanks in advance

[Dovecot] move mail from server with v1.0 to server w. v2.1?
by Frank Lienhard 06 Feb '13

06 Feb '13

I'm about to replace my old server. Both servers are on my internal network. The old one ist running debian lenny(32bit) with dovecot 1.0.15 and the new one debian Wheezy with dovecot 2.1.7. I set up the users on both systems identically (same gid uid). My first attempt was tho simply rsync the Maildirs along with the homes. Both deovecot versions are set up with the maildir format, but this results in ~30% doublicated mails on the new server. I then learned about doveadm/dsync, only to figure out that this isn't available in v 1.0.15 and therefor won't work. So which could be the most painless way to solve that?

[Dovecot] dsync backup questions
by Joe Beaubien 06 Feb '13

06 Feb '13

Hi, I'm currently trying to setup remote backups of my emails but i'm running into issues (mdbox format, indexes and storage in the same folder hierarchy). Local backup command: dsync -u "my_user" backup /backups/my_user (1) Recently, I noticed that the local backup takes up twice the size as the original mail location (8gb vs. 4gb). I purged alot of emails from the original location, so the size shrunk, but the local backup just keeps on getting bigger. I couldn't find any dsync option that would delete extra emails. - Question: Why isn't the local backup synced properly and remove the extra emails? (2) What is the best why to copy this local backup to a remote location that does NOT have the possibility to run dsync. - Question 1: is rsync safe to use and will this data work for restore? - Question 2: Would it be safe to simply rsync the original mail_location to the remote server? I searched the net, but it seems that mdbox is tricky to backup. Thanks in advance, -Joe

[Dovecot] lmtp-proxying in 2.1 slower than in 2.0.14 ?
by Jan-Frode Myklebust 05 Feb '13

05 Feb '13

We upgraded our two dovecot directors from v2.0.14 to dovecot-ee 2.1.10.3 this week, and after that mail seems to be flowing a lot slower than before. The backend mailstores are untouched, on v2.0.14 still. After the upgrade we've been hitting process_limit for lmtp a lot, and we're struggeling with large queues in the incoming mailservers that are using LMTP virtual transport towards our two directors. I seem to remember 2.1 should have a new lmtp-proxying code. Is there anything in this that maybe needs to be tuned that's different from v2.0 ? I'm a bit scheptical to just increasing the process_limit for LMTP proxying, as I doubt running many hundreds of simultaneous deliveries should work that much better against the backend storage.. ###### doveconf -n ########## # 2.1.10.3: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.32.1.el5 x86_64 Red Hat Enterprise Linux Server release 5.5 (Tikanga) default_client_limit = 4000 director_mail_servers = 192.168.42.7 192.168.42.8 192.168.42.9 192.168.42.10 192.168.42.28 192.168.42.29 director_servers = 192.168.42.15 192.168.42.17 disable_plaintext_auth = no listen = * lmtp_proxy = yes 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 passdb { args = proxy=y nopassword=y driver = static } protocols = imap pop3 lmtp sieve service anvil { client_limit = 6247 } service auth { client_limit = 8292 unix_listener auth-userdb { user = dovecot } } service director { fifo_listener login/proxy-notify { mode = 0666 } inet_listener { port = 5515 } unix_listener director-userdb { mode = 0600 } unix_listener login/director { mode = 0666 } } service imap-login { executable = imap-login director process_limit = 4096 process_min_avail = 4 service_count = 0 vsz_limit = 256 M } service lmtp { inet_listener lmtp { address = * port = 24 } process_limit = 100 } service managesieve-login { executable = managesieve-login director inet_listener sieve { address = * port = 4190 } process_limit = 50 } service pop3-login { executable = pop3-login director process_limit = 2048 process_min_avail = 4 service_count = 0 vsz_limit = 256 M } ssl_cert = </etc/pki/tls/certs/pop.example.com.cert.ca-bundle ssl_key = </etc/pki/tls/private/pop.example.com.key protocol lmtp { auth_socket_path = director-userdb } ################ -jf

[Dovecot] dsync-local(user): Error: proxy client timed out
by Metro Domain Admin 05 Feb '13

05 Feb '13

Hello, I have an intermittent but frequent problem using dsync backup. The command outputs: dsync-local(user): Error: proxy client timed out Then dies with exit code 75. Any subsequent attempts to re-run the backup invariably fail like this: dsync-local(user): Warning: Destination mailbox INBOX has been modified, need to recreate it before we can continue syncing dsync-local(user): Error: read() from worker server failed: EOF dsync-local(user): Error: msg-copy returned invalid input: dsync-local(user): Error: remote: dsync-remote(user(a)domain.com): Error: Can't delete mailbox INBOX: INBOX can't be deleted. dsync-remote(l_user(a)domain.com): Error: command MSG-SAVE failed dsync-local(user): Warning: Mailbox changes caused a desync. You may want to run dsync again. The syntax I am using is: dsync -u $user backup \ ssh -i <idfile> <user@host> \ dsync -u l_$user We have this running in a script that loops through all users. The error happens mostly on the larger mailboxes but I've seen it succeed on the largest ones then fail on smaller. One mid-sized account now fails consistently. The backup is running from a Mac OS PPC server running 2.1.12 The target is a Linux Intel box running 2.1.13, but I had the same problem sending to a Mac OS Intel on 2.1.12. Mdbox in all cases. Thanks, Tony

[Dovecot] Overloading IMAP Server
by Harford, Ken 04 Feb '13

04 Feb '13

Hi All, I am having an issue with dovecot IMAP reading and writing to one specific mailbox. I have a check email delivery script that sends out a email and then logs into dovecot to check if the mailbox that the message has been delivered to. However, the servers that send these messages send them in bunches depending on how many postfix spools it is checking. So I could get 60 messages all being sent to 1 mailbox and then having to read that same mailbox to check if the message actually got delivered. I am using postfix as the MTA and dovecot is actually delivering the message to the mailbox I am getting a lot of errors such as the following: Could not connect to IMAP server imap failed: IMAP RECEIVE CRITICAL - Could not select INBOX Any ideas as to what I can tweak in dovecot to allow these messages to be verified. Thanks for any information or help you could provide!! Ken

[Dovecot] Reviewing end-user ham/spam submissions before feeding them to sa-learn via Dovecot Antispam plug-in
by Ben Johnson 01 Feb '13

01 Feb '13

Currently, I'm using the Dovecot Antispam plug-in with great success. Everything works as expected. However, I would like to change the plug-in's behavior such that it simply sends a copy of a message that is moved from Inbox -> Junk (or Junk -> Inbox) to an administrator, instead of calling sa-learn (I'm using SpamAssassin) automatically. Basically, I would like to be able to review messages that end-users submit for training before they are actually fed to sa-learn. Has anyone had a similar need? If the Antispam plug-in already supports this, if the necessary commands can simply be added to the shell script that Antispam calls, or if there is a better method altogether, any help is greatly appreciated. Thank you! -Ben

[Dovecot] Dovecot Director Doveadm fails when there are a lot of output information
by Ramon Frontera 31 Jan '13

Hi, we are running dovecot 2.1.13 We have 2 proxies with director and 4 mail servers. we use LDAP when we execute doveadm-quota -A and doveadm with few output lines, its works fine. When we use doveadm-search or doveadm-mailbox with a lot of output information the command stops the execution and the command no ends. The connection to one of the 4 mailserver has finished at this moment. I have made some tests and i have found that if we use only one mailserver the commands works fine. I put the gdm bt output hope it help you.

[Dovecot] sieve_max_redirects=0 not working as documented
by Arnaud Abélard 31 Jan '13

31 Jan '13

Hello I'm trying to keep my users from using the "redirect" action with pigeonhole from dovecot 2.0.21. As documented in http://wiki2.dovecot.org/Pigeonhole/Sieve/Configuration I configured sieve like this: plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_max_redirects = 0 } (and doveconf indeed shows the new setting for sieve_max_redirects) Unfortunately I can still use the redirect action: lda(dummy(a)univ-nantes.fr): Debug: sieve: executing script from /vmail/d/u/dummy/.dovecot.svbin lda(dummy(a)univ-nantes.fr): sieve: msgid=<510A758D.1030305(a)univ-nantes.fr>: forwarded to <xxxx(a)xxxxx.com> what could I have missed?

[Dovecot] v2.1.14 released
by Timo Sirainen 30 Jan '13

30 Jan '13

http://dovecot.org/releases/2.1/dovecot-2.1.14.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.14.tar.gz.sig If you've been waiting for a fully stable release after the recent cache file troubles in v2.1.11+, this release should be the one. Hopefully there won't be v2.1.15 anytime in near future. (v2.2.rc1 does look close though.) BTW. I know there are quite a lot of mails I haven't replied to in dovecot list. Too busy for now.. + doveadm acl recalc command added - v2.1.11+ had a race condition where it sometimes overwrote data in dovecot.index.cache file. This could have caused Dovecot to return the same cached data to two different messages. - mdbox: Fixes to handling duplicate GUIDs during index rebuild

[Dovecot] decode2text.sh
by bhs692-dove＠yahoo.com 30 Jan '13

30 Jan '13

Dovecot version: 2.1.13 OS: Centos 6.3 CPU: 64bit x86 There appear to be two related errors in the decode2text.sh file (which can be used for indexing/ searching attachments). - The layout of "$formats" has repeated values for pdf, ppt, etc, so you should only match the pattern once by adding -m1 - The layout of "$formats" has the file extension in the second "column", so the "start of line"(^) match doesn't work as is. Original problem line (from ./src/plugins/fts/decode2texh.sh): fmt=`echo "$formats" | grep -w "^$content_type" | cut -d ' ' -f 2` Here are two options that appear to solve the problem. The first option is probably preferred, since it matches exactly the extension to the second "column". 1) switch the order of commands (cut & grep) and add -m1. for example: fmt=`echo "$formats" | cut -d ' ' -f 2 | grep -w -m1 "^$content_type"` -OR- 2) add "m1" and remove "^". for example: fmt=`echo "$formats" | grep -w -m1 "$content_type" | cut -d ' ' -f 2`

[Dovecot] passdb to add extra fields?
by Timo Sirainen 30 Jan '13

30 Jan '13

Some passdbs like PAM can't really return any extra fields. Also some people have wanted to combine users' data from different passdb/userdbs so that for example you'd have userdb passwd give the uid/gid/home, but then you'd also have some other userdb give quota limits. So I was thinking something like this: passdb { driver = pam } passdb { driver = sql include = yes } or: userdb { driver = passwd } userdb { driver = passwd-file include = yes } I'm not sure about two things: 1) Should there be a way to replace all of the existing fields instead of just adding new ones? 2) Any thoughts of a better name than "include"? With passdb it would mean that it's included only when the authentication failed for some other passdb. With userdb it means it's included only if a previous userdb lookup succeeded. Also there are already "deny" and "pass" settings. Interaction with them can be somewhat confusing.. Maybe all of these should be replaced with: type=deny: Same as old deny=yes (deny auth if user is in list) type=precondition(?): Same as pass=yes (require another passdb to match) type=postcondition(?): Require user to exist in this passdb/userdb as well, adding any extra fields in it. type=add: Add any extra fields, if the user exists at all. (Better ideas for the names here? Is even "type" a good name?) Then maybe a new setting to delete existing extra fields .. or perhaps just extend passdb { override_fields } so that having "-field" would delete the field if it already existed..

[Dovecot] A lot of dovecot/imap processes
by Juan Cifo Servera 30 Jan '13

30 Jan '13

Hello! I have a dovecot installed and many users could login via IMAP over SSL (40 users at same time aprox). Users could have "Check mail every X time" enabled in their client (Thunderbird or K-9 mail) - Is this required feature? I noted that if I disable it I still getting news mails without having to check for new mails manually - . I noted that dovecot is creating a lot of process (dovecot/imap and dovecot/imap-login) and is requiring more and more RAM. I think that every login starts a process but never is endend. The output of /*ps aux | grep dovecot | wc*/ is increasing until 250 lines aprox. I think that is limited by process_limit = 256. But if I put process_limit = 100, in the log appers a message that dovecot is aborting logins (and I noted that new connections sometimes couldn't login). Anyway the mailserver is working well, but I'm afraid of the consumtion of RAM. Is that normal?

[Dovecot] help with public namespace/mailbox
by michael＠los-pollos.co 30 Jan '13

30 Jan '13

Dear all, I am hoping someone can help me with a problem that I have been trying to fix for days. Using postfix and dovecot 2.0.19 on Ubuntu 12.04 with LDAP authentication and virtual users and domains. Basically I want to setup both shared and public mailboxes. The shared part is working fine, ie I can share folders successfully and other uses can see them. However when I try and create sub folders in the public folder they don't show up in the client. I have tried creating them in manually in the filesystem ie mkdir .folder and also via thunderbird. I have read through the dovecot wiki's several times over and still cannot see why it won't work. I have debug turned on and these are the log messages I get in syslog when I start up thunderbird: acl: No lookup right to mailbox: public/folder acl vfile: file /home/example.com/public/.folder/dovecot-acl not found acl vfile: file /home/example.com/public/dovecot-acl not found So I create the dovecot-acl file manually in public and set the right file system permissions and the errors go away, yet the folder still doesn't get created despite the following getting logged in syslog. Jan 29 23:43:57 alpha dovecot: imap(testuser(a)example.com): Debug: Namespace public/: /home/example.com/public/.folder2 doesn't exist yet, using default permissions Jan 29 23:43:57 alpha dovecot: imap(testuser(a)example.com): Debug: Namespace public/: Using permissions from /home/example.com/public: mode=0777 gid=-1 Right now I am thinking the problem might be that I am trying to setup both shared and public namespaces within the same configuration and therefore dovecot is looking for acl's for the public when it shouldn't be? Feel like I am stabbing in the dark with this though. Any help anyone can offer will be greatly appreciated! Thanks in advance. Regards, Michael.

[Dovecot] dovecot.index is missing
by Alexandr Sabitov 29 Jan '13

29 Jan '13

Dear All, I have noticed that dovecot.index is not generated straight away if you have just a few emails in the mailbox. Instead of that dovecot.index.log is modified and accessed by clients. Only if the number of email reaches some level then it creates dovecot.index in user mailboxes. Can somebody please tell me when (in my understanding of the process) the index log file drops all data into the mail index file. What does trigger that ? Sorry I couldn't find any info on that in the wiki. Best Regards, Alexandr Sabitov

[Dovecot] password schemes in dovecot
by Public 27 Jan '13

27 Jan '13

Hey there, I'm using the latest dovecot 2.1.13 In the wiki http://wiki2.dovecot.org/Authentication/PasswordSchemes BLF-CRYPT is listed, but i can't use it. "doveadm pw -l" doesn't show it. And i'm unsure about how I am supposed to use the different SHA schemes, since they always output different hashes for the same password. MD5 is working fine, but I'd rather not use it. Is the wiki outdated or how do i get BLF-CRYPT working? thanks, simon

[Dovecot] From Sendmail to Dovecot mdbox, what is missing.
by Torpey List 27 Jan '13

27 Jan '13

Sendmail 8.14.4 dovecot 2.0.9 I have sendmail working and it is sending mail to /var/mail/%u. I have dovecot working in that I can move emails into IMAP folders and I can send email through IMAP. I have set up dovecot to use mdbox based on the following: mail_location = mdbox:~/mail However, I seem to be lacking a key piece of information. Sendmail is sending the mail to /var/mail/%u as a mbox (single file for all emails) format. Dovecot wants to read the mail in mdbox (Multiple messages per file, but unlike mbox multiple files per mailbox.) So the two programs are not working together. So, I cannot get dovecot to read new emails at /var/mail/%u. So I tried changing to the following: mail_location = mdbox:~/mail:INBOX=/var/mail/%u However, dovecot complains that it is NOT a directory. That is because sendmail is sending as mbox format. I have tried two lines of “mail_location” but that did not work. example mail_location = mdbox:~/mail ----> for dovecot mail_location = mbox:INBOX=/var/mail/%u -----> for sendmail I have tried LMTP and dovecot-lda. LMTP – I could not see any difference with this added or not. Dovecot-lda – I have had issues getting it configured. Thanks for any help!

[Dovecot] mbox INBOX out of sync (?)
by Tinguaro Barreno Delgado 26 Jan '13

26 Jan '13

Hello all, I've running a Dovecot's installation for several years without problems but since last system upgrade (Dec 26) I'm facing a kind of sync issue with the /var/mail/ inbox files. We have got mobile and desktops IMAP clients (mostly Mozilla Thunderbird). The problem is that /var/mail/ files (mbox) aren't updated: we can delete mail from clients but they persist in de /var/mail, so the same user can see the mail again from other IMAP client. Logs seems to be correct. Many thanks in advance.

[Dovecot] Dovecot unable to access the shadow file
by kenwood 25 Jan '13

25 Jan '13

I am installing Dovecot-2.1.13 on Slackware 13.37.0 for the first time to replace ipop3d and I have overcome all of the roadblocks as they have developed except this last one and I finally have to say “uncle”. The error messages that are showing up in the dovecot.log are as follows. Jan 24 12:27:27 tux2 dovecot: auth: Error: passwd-file /etc/shadow: open(/etc/shadow) failed: Permission denied (euid=202(dovecot) egid=202(dovecot) missing +r perm: /etc/shadow, we're not in group 43(shadow), dir owned by 0:0 mode=0755) Jan 24 12:27:27 tux2 dovecot: auth: passwd-file(user,192.168.10.2,<pw3xHwzUSQDAqAoC>): no passwd file: /etc/shadow Jan 24 12:27:29 tux2 dovecot: pop3-login: Warning: SSL alert: where=0x4008, ret=256: warning close notify [192.168.10.2] Jan 24 12:27:29 tux2 dovecot: pop3-login: Disconnected (auth failed, 1 attempts in 2 secs): user=<user>, method=PLAIN, rip=192.168.10.2, lip=192.168.10.100, TLS: Disconnected, session=<pw3xHwzUSQDAqAoC> Based on what I have read the only user that should access the shadow file is root. With that in mind I looked at all the configuration and .ext files and the only file I could find that would indicate that root should be checking the shadow file is 10-master.conf. In that file it said the default service auth-worker was root but since it was apparently not working I removed the hash mark and made it explicit. It still didn’t work. As a last resort even though it was not good practice I tried adding user dovecot to the group shadow but that did not work either. It still says dovecot is not in the group shadow even though it is. Any suggestions? -- View this message in context: http://dovecot.2317879.n4.nabble.com/Dovecot-unable-to-access-the-shadow-fi… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] dovecot 2.1.13, proxy and nologin extras field
by Marco Giunta 24 Jan '13

24 Jan '13

Hi at all, in our test environment, I'm playing with dovecot 2.1.13 configured as imap/pop/managesieve proxy. It is configured to authenticate users with ldap and it works very well. Now, I'd like to temporary disable some users's login, because we are moving to another storage, and I wouldn't stop imap service at all. I've found on Dovecot wiki that I could use 'nologin' extra field, but I wasn't been able to get it work. My dovecot configuration is: # 2.1.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.19.1.el6.x86_64 x86_64 ... auth_debug = yes auth_debug_passwords = yes auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no listen = * mail_debug = yes 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 mbox_write_locks = fcntl 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 { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap pop3 sieve service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } } ssl = no ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = prefetch } and my 'dovecot-ldap.conf.ext' is: uris = ldap://ldap.example.it/ dn = "cn=Reader,dc=example,dc=it" dnpass = password base = ou=People,dc=example,dc=it pass_attrs = uid=user,userPassword=password,\ =userdb_home=/var/spool/mail/%1u/%u,uidNumber=userdb_uid,gidNumber=userdb_gid,\ =proxy=y,=host=imap.example.it,\ =nologin=y pass_filter = (&(objectClass=qmailUser)(uid=%u)(accountStatus=active)) With this configuration, all users can login, and log said: Jan 23 09:16:18 localhost dovecot: master: Dovecot v2.1.13 starting up (core dumps disabled) Jan 23 09:16:33 localhost dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Jan 23 09:16:33 localhost dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Jan 23 09:16:33 localhost dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Jan 23 09:16:33 localhost dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so Jan 23 09:16:33 localhost dovecot: auth: Debug: auth client connected (pid=3660) Jan 23 09:16:33 localhost dovecot: auth: Debug: client in: AUTH#0111#011PLAIN#011service=imap#011session=PsbzT/DT+gCTeiwf#011lip=192.168.129.109#011rip=192.168.44.31#011lport=143#011rport=53754 Jan 23 09:16:33 localhost dovecot: auth: Debug: client passdb out: CONT#0111#011 Jan 23 09:16:33 localhost dovecot: auth: Debug: client in: CONT#0111#011AHByb3ZhZm0AY2hlcGFsbGU= Jan 23 09:16:33 localhost dovecot: auth: Debug: ldap(prova,147.122.44.31,<PsbzT/DT+gCTeiwf>): pass search: base=ou=People,dc=example,dc=it scope=subtree filter=(&(objectClass=qmailUser)(uid=prova)(accountStatus=active)) fields=uid,userPassword,uidNumber,gidNumber,uid,uid Jan 23 09:16:33 localhost dovecot: auth: Debug: ldap(prova,192.168.44.31,<PsbzT/DT+gCTeiwf>): result: uid=prova uidNumber=2944 gidNumber=650 userPassword={MD5}BjbsTtSovVAs1csswBTI7Q== Jan 23 09:16:33 localhost dovecot: auth: Debug: client passdb out: OK#0111#011user=prova#011proxy#011host=imap.example.it#011nologin#011hostip=192.168.11.136#011pass=password Jan 23 09:16:33 localhost dovecot: imap-login: proxy(prova): started proxying to imap.example.it:143: user=<prova>, method=PLAIN, rip=192.168.44.31, lip=192.168.129.109, session=<PsbzT/DT+gCTeiwf> As you can see 'nologin' field is present in 'passdb' answer, but it doesn't seem to work.

[Dovecot] Permissions when running `dovecot --exec-mail imap`
by Tim Marston 23 Jan '13

23 Jan '13

Hi, I'm running dovecot 1.2.15, on Debian squeeze. /var/mail is owned by group "mail" with permissions "g+rwxs,o=". The mail_privileged_group setting is set to "mail". I am trying to access mail on a remote machine with mutt by tunnelling mutt though ssh and running `dovecot --exec-mail imap` on the mail server. But I frequently get errors in the mail server's logs about not being able to create dotlock files when accessing my INBOX this way. This makes sense -- I'm running dovecot as a regular user, so it isn't able to write to /var/mail as group "mail". I notice that on the dovecot wiki[1] it is suggested that sudo is used to set uid/gid before running `dovecot --exec-mail imap`. But I don't actually want to set the uid, just the gid. And I also have sudo disabled at the moment. So I was wondering about another solution... Would it be acceptable to setgid the dovecot executable and change it's group to "mail" (i.e., `chgrp mail dovecot` and `chmod g+s dovecot`)? Would this pose some kind of security risk? Would this actualy do what I want, or am I missing a bigger picture? Kind regards, [1] http://wiki.dovecot.org/PreAuth -- Tim Marston ed.am

[Dovecot] warning regarding quota and mboxes
by Andreas Meyer 23 Jan '13

23 Jan '13

Hello! We drive mboxes and maildirs and the dovecot-server is running very well and everthing is fine, but I get the following warning in the dovecot-lda-errors.log when a mail is delivered to a mbox. Jan 10 16:29:24 lda(archiv(a)bitcorner.de): Warning: quota: Namespace '' is not Maildir, skipping for Maildir++ quota This is what I defined in the dovecot.conf: mail_home = /var/spool/vhosts/%d/%n mail_location = mbox:~/:maildir:~/ mail_plugins = quota plugin { quota = maildir:User quota quota_rule = *:storage=500MB quota_rule2 = Trash:storage=+10%% } Can I avoid the error above somehow? Namespaces are a bit mysterious for me at the moment. Greetings Andreas

[Dovecot] speed up dovecot IMAP server
by Bernics Gábor | Penta Unió Zrt. 23 Jan '13

23 Jan '13

Hello, I upgraded my dovecot server (1.2 -> 2.1), from debian backport because it was a little slow (wait 5-6 sec) when I opened some mail (but not every mail). Unfortunately, the mail open speed didn't increase. I think it's an index problem. Have you idea for fixing?

[Dovecot] Fixing bad maildir message sizes
by Richard Platel 22 Jan '13

22 Jan '13

Hello. As stated in my previous message, we have some old compressed maildir messages with incorrect sizes in the filename. These messages cause dovecot 2.x problems. I'm trying to write a script to crawl all our messages, check the actual message size and if necessary, fix the filename. However, when I do this, dovecot gives the message a new UID on next login. If I change the filename in dovecot-uidlist, dovecot still gives a new UID on next login. If I change dovecot-uidlist and delete the index, then the UID is preserved. Re-indexing our millions of mailboxes is not a great solution for us. Is there a good way to fix this?

[Dovecot] question on "doveadm user" and pass/userdb
by Gábor Lénárt 22 Jan '13

22 Jan '13

Hi, I'm about getting to know dovecot in details, I am about the command "doveadm user". The man page shows this example: userdb: jane uid : 8001 gid : 8001 home : /home/jane mail : sdbox:~/sdbox plugins : sieve quota_rule: *:storage=150M It seems to be nice, however I never got this only: ~# doveadm user lgb@office userdb: lgb@office That's all. The dovecot test configuration works otherwise via IMAP/POP3/LMTP nicely. What I guess that the lack of extra information (which would be needed by some scripts of mine, eg for getting user's home easily from shell scripts, as it's hash based, etc) is caused because I don't pass home (and/or other settings) back from userdb and/or passdb. However I do have these in global scope: mail_home = /mailstorage/%Ld/%Ln (yes, this is not hashed at all at the momement but it will be soon) mail_location = maildir:~/Maildir mail_uid = vmail mail_gid = vmail (... and also some global quota stuffs configured in plugin section) Now, I am a bit confused: even with passdb/userdb does not return with user home or GID/UID, dovecot knows these in case of pop3/imap/lmtp access, since these information can be "composed" from those settings. But then, wouldn't it possible so "doveadm user" shows those as well, like lmtp/pop3/imap can resolve those too? Honestly, it's a bit redundant to put needed information into user and pass attrs in every dbs (I have some) when dovecot knows those otherwise ... If I interpret "doveadm user"'s goal wrong (it's just for userdb/passdb query tool nothing more), is there any tool which works in this config, displaying extra information (at least user's home), or should I create some script which just repeats the functionality of dovecot's configured mail_home resolution? Thanks.

[Dovecot] Mail logger question
by Hungerburg 21 Jan '13

21 Jan '13

I use Dovecot simply as a way, to provide an e-mail archive for people on the LAN, where they can move messages into from within thunderbird. Mails are stored in a maildir of one system user where all the people know the password of. This was very easy to setup in ubuntu 12. Today I started using the mail_log plugin to provide an audit trail. Now I am looking for a light way, to get the log reflect the different people or principals. One way is, to create users with the same ID in the passwd and shadow files, but I'd rather have them in a separate file, something like a list of aliases for the system user. Can you suggest a simple way, without going virtual users? Below the relevant info on dovecot: $ dovecot --version 2.0.19 $ dovecot -n # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-35-generic x86_64 Ubuntu 12.04.1 LTS mail_plugins = " fts fts_squat mail_log notify" passdb { driver = pam } plugin { fts = squat fts_squat = partial=4 full=10 mail_log_events = save delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size from subject } protocols = " imap" ssl_cert = </etc/ssl/certs/ssl-cert-snakeoil.pem ssl_key = </etc/ssl/private/ssl-cert-snakeoil.key userdb { driver = passwd } Thank you all -- peter

[Dovecot] %d in configuration file does not work
by Jens Tobiska 19 Jan '13

19 Jan '13

I am trying to set up dovecot in a postfix virtual account/domains setting. In the configuration file I would like to use %d in two places, for: mail_location = /var/mail/vhosts/%d/%n and to specify the location of the respective passwd file: passdb passwd-file { args = /etc/auth/%d/shadow } Looking at the logs, %d is empty while %n works, so dovecot is looking for something in /var/mail/vhosts//myname and /etc/auth//shadow which don't exist. Replacing %d in dovecot.conf with the actual domain name works. So, the quesiton is, why is %d empty, and from where does it take its value?
