[Dovecot] FTS autoindex username problem
by lee_yiu_chung＠yahoo.com 11 Apr '14

11 Apr '14

I tried to set up Solr search server according to http://wiki2.dovecot.org/Plugins/FTS/Solr, and turned on autoindexing according to http://wiki2.dovecot.org/Plugins/FTS, but I found a strange behaviour that cause server search missing some emails. Here is the login information of my mail server: login name: user1 email: user1(a)example.com Now, when I turned on autoindexing, all autoindexed email are indexed using user1(a)example.com as username key, as shown in maillog: dovecot: [ID 12345 mail.info] indexer-worker(user1(a)example.com): Indexed 1 messages in INBOX But when I triggered on-demand indexing using IMAP server search, the emails are indexed using user1 as username key instead, as shown in maillog: dovecot: [ID 12345 mail.info] indexer-worker(user1): Indexed 1799 messages in INBOX Only the emails indexed using user1 can be searched, emails indexed using user1(a)example.com cannot be found. How can I configure autoindex to index email using user1 as username key? --- (Below is a follow-up question) In my mail server config, there are a few virtual mailbox users are using the following login information instead (different auth/password backend): login name: user2(a)virtmail.example.com email: user2(a)virtmail.example.com In this case, how can I distinguish user1(a)example.com and user2(a)virtmail.example.com, so that emails for user1(a)example.com can be indexed using user1 as username key, while user2(a)virtmail.example.com can be indexed using user2(a)virtmail.example.com as username key?

Re: [Dovecot] replication + attachment sis + zlib bug ? (HEAD version from xi.rename-it.nl)
by Pavel Stano 11 Apr '14

Yes, exactly. I look at the code and find out there is functionality for that. Dovecot store attachments in base64 format without decoding if there are longer lines with more base64 blocks (4chars). So these attachments get deduplicated but are not decoded. But it don't work if last line is buggy. I think i fixed it. It looks like it works, but i test only one mailbox.

[Dovecot] FTS autoindex problem
by lee_yiu_chung＠yahoo.com 11 Apr '14

11 Apr '14

I tried to implement a solr search server, but I found some unexpected behaviour when I turn on autoindex according to http://wiki2.dovecot.org/Plugins/FTS. I found that all autoindexed email are using "user1(a)example.com" as username, as shown in maillog: indexer-worker(user1(a)example.com): Indexed 1 messages in INBOX However, all manually indexed email (triggered by IMAP server search) are using "user1" as username, as shown in maillog: indexer-worker(user1): Indexed 2927 messages in INBOX. I am using "user1" as login name, so all autoindexed mails don't appear in search result. How can I use "user" as the username in autoindex? BTW, I do have a few mailboxes in the format user2(a)virtualmail.example.com, which requires full email address as the login name. How can I autoindex emails that automatically distinguishes user1(a)example.com (using "user1" as username) and user2(a)virtualmail.example.com (using "user2(a)virtualmail.example.com" as username) given that the previous question is solved?

[Dovecot] replication + attachment sis + zlib bug ? (HEAD version from xi.rename-it.nl)

[Dovecot] dsync deleted my mailbox - what did I do wrong?
by Benjamin Podszun 10 Apr '14

10 Apr '14

Hi. Mostly annoying: I migrated from one machine to another, made sure the target host worked as expected, updated mx records and - after a couple of days - signed it off as good. This is just my private machine, no big deal if something goes wrong.. Everything's fine? Good, let's migrate my inbox from the old machine. There's no direct connectivity between those servers, so what I did was: (old server) sudo -u vmail dsync -u dar(a)darklajid.de backup maildir:/tmp/mail_backup/ Works fine, got my maildir. Tar'd it up, moved it to the new server. Now how do I import those mails? Ah, let's use the same command, with -R? (new server) sudo -u vmail dsync -u dar(a)darklajid.de -R backup maildir:/tmp/mail_backup Error: Mailbox INBOX sync: mailbox_delete failed: INBOX can't be deleted. Wait. What? Sure enough, the last couple of days are gone, the target mailbox is completely empty. I read the man page over and over again, but failed to see the problem. I even thought for a moment that _maybe_ dsync backup is one-way only (even if that failed as well) and tried the same command with mirror. Exactly the same output, same result, empty target mailbox. In the end I succeeded to import the mails with doveadm import, completely lost a number of days of mails. My fault, sloppy not to back the up again, but I still don't think that this should happen. Ever. My question now is: - where did I fail (ignoring the backups, please. That's .. something I know) - Can I use dsync ... for backups? I don't think that this is a good idea after yesterday night? - Should dsync EVER try to delete mailboxes? Even 'special' mailboxes? Should it warn about that, asking for a --force switch or something? Any insights would be appreciated. At this point the damage is done, but I'd like to learn how to do better. Ben

[Dovecot] integration of old mails into new dovecot Maildir
by K. C. Mohan - Personal 10 Apr '14

10 Apr '14

I just installed dovecot 2.2.9 on to a new server and want to transfer all the old mails into the email accounts I imported from the previous server into MySQL database. I am not able to view the subfolders and or old mails that I copied into their respective maildir folders. I was very much appreciate if anyone could let me know how to import old mails into the new server. All I see, is the new mails that have come into the account since I started dovecot service in the new server. --- This email is free from viruses and malware because avast!

[Dovecot] Heartbleed openssl vulnerability?
by John Rowe 10 Apr '14

10 Apr '14

Do we know if dovecot is vulnerable to the heartbleed SSL problem? I'm running dovecot-2.0.9 and openssl-1.01, the latter being intrinsically vulnerable. An on-line tool says that my machine is not affected on port 993 but it would be nice to know for sure if we were vulnerable for a while. (Naturally I've blocked it anyway!). Thanks John

[Dovecot] Director NFS backups
by Murray Trainer 10 Apr '14

10 Apr '14

Hi All, What is the recommended method of taking backups of user mailboxes when using the Director setup with NFS backend mail storage? Is there any way to avoid the likely NFS locking issues by backing up the filesystem directly or do I have to do some sort of dsync method. If I have to use dsync can I dsync the mailboxes to compressed copies of the mailboxes without requiring another dovecot server to do the dsync. Thanks for you responses. Murray

That ought to be the default: http://wiki2.dovecot.org/POP3Server (Section Session locking) Did you set pop3_lock_session=yes somewhere? Locking is good if the client connection is stable: if you disable locking, you could end up with a scrambled mailbox as two or more users access it at the same time.

[Dovecot] Override maildir for just a few users
by Charles Marcus 10 Apr '14

10 Apr '14

Hi all, Currently, I have mail_location = maildir:~/Maildir set and all passdb and userdb lookups are SQL based (doveconf -n pasted below). However, I want to override the users maildir location - and *only* the maildir location - for just a few users. I was thinking the easiest way would be to add a simple flat file based userdb that is checked before the SQL based one, where I can define a different maildir for these users. So, basically, dovecot checks the flat file first, and if the user isn't found, falls back to SQL. I still want all AUTH to go through SQL... It seems like this should be fairly simple, but after reading the wiki for a few days, I'm just not sure... This is on a production box, so I have to be careful (note to self - MUST set up testing box for things like this)... Is anyone else doing anything like this, and if so would you be willing to share sanitized configs? Thx, -- Best regards, Charles

[Dovecot] Sieve (randomly?) flagging messages as \\Seen \\Deleted
by Emanuele Balla (aka Skull) 09 Apr '14

09 Apr '14

Hi, I'm trying to debug (without great results, so far) a very weird behaviour in my environment. Sorry if this came out in another form before, but I've not been able to find out anything resembling what I'm experiencing, so far... OS is a debian wheezy and dovecot is the version provided by the OS: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.4 The system uses postfix with virtual users, credentials and maildir locations stored on mysql, local delivery through LMTP and sieve+managesieve available to users (although managesieve only listens on localhost and is only usable through the webmail interface). FWIW, I've been running 10-20 systems just like this one (mostly with earlier dovecot versions and using LDA when LMTP wasn't available yet) for many years, and this is the very first time I'm so puzzled I end up searching for help here :-| Even though the system has been working for months (more or less 1 year now) without big changes, a strange behaviour appeared (or became evident enough to be noticed) in the last few days, apparently involving sieve and some sort of "default/hidden" action triggered by something. Or at least that's what I ended up supposing. The problem in short: Messages I expected to find in certain folders were simply not there, although sieve logs reported them as delivered in those same folders. By manually inspecting the maildir, I actually found the messages, but they were all flagged as \\Seen + \\Deleted and therefore not displayed by the MUA (ThunderBird in my case). I initially supposed this to be a TB issue, 'cause nothing in my sieve script ever flags messages that way, but I could not find anything on my client explaining that. Then I received a notification from one of my users saying he was experiencing exactly the same, except he's using mutt as IMAP client; that restricted the issue to server-side interactions only, but nothing useful could be found in logfiles... This is the "relevant" portion of a "dovecot -n" output: [...] plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +vacation-seconds +editheader sieve_vacation_default_period = 2d sieve_vacation_dont_check_recipient = yes sieve_vacation_max_period = 30d sieve_vacation_min_period = 2s sieve_vacation_use_original_recipient = no } [...] protocol lmtp { mail_plugins = sieve hostname = alternativename.bofhland.org } There is no sieve_(before|after) script in addition to what users create for themselves. The mailboxes are relatively low-traffic; most of the traffic is caused by a single role address translated into multiple-recipients alias going to many of the users (100-300 messages per day). Almost all the users using sieve rely on it to store traffic for that role-address in a dedicated folder, including the mutt user and myself. Not that's all that important, but means that most of the misbehaviours observed (but not all) are observed in these folders. I enabled mail_debug, but there's nothing unusual in there AFAICT: it just says: - using the following location for user's Sieve script: /blabla/.dovecot.sieve - opening script /blabla/.dovecot.sieve - script binary /blabla/.dovecot.svbin successfully loaded - not saving binary /blabla/.dovecot.svbin, because it is already stored - executing script from /blabla/.dovecot.svbin - stored mail into mailbox 'DedicatedFolder' And it does, except the message happens to be flagged as seen and deleted... In order to try restricting what may be causing the issue, I added... removeflag "\\Deleted"; removeflag "\\Seen"; ...to the rule sending messages to the dedicated folder cited above for my mailbox. The problem apparently disappeared for me as long as I kept those in place. This should mean (I suppose) that the decision of flagging messages that way is taken before the users' sieve scripts are applied (sort of "hidden sieve_before"). The problem is hard to replicate as it's apparently not deterministic: the same message is being flagged for one user but not for the other, different messages between the same people and with the same thread are sometimes flagged and sometimes not. Something is surely triggering whatever is causing this, but it's not evident enough for me to point a finger and say "ha ha!" (https://www.youtube.com/watch?v=rX7wtNOkuHo) So, a question for people knowing pigeonhole's internals: does it ever choose to mark messages as described above for any reason? If yes, I may be triggering this behavior with something I recently added/modified, and at least I'll have something to focus my investigation on. :-| Any other suggestion is obviously welcome...

[Dovecot] sieve pigeonhole vacation filter responding when recipient is not explicitly listed
by Milan Cvetkovic 09 Apr '14

09 Apr '14

Hi dovecot.org, When I set up vacation filter for a mailbox, the vacation response is generated even though none of the addresses in the email are same as the mailbox address itself. I have example email sent to "aliastouser(a)mpathix.com" which gets delivered to "user(a)my.domain.com" by dovecot-lda. The invocation command is: # /usr/lib/dovecot/dovecot-lda \ -d user \ -f john.doe(a)somewhere.com \ -a aliastouser(a)mpathix.com \ -p /tmp/test.email # cat /tmp/test.email Message-ID: <test3> From: John Doe <john(a)somewhere.com> To: aliastouser(a)mpathix.com Subject: test3 vacation response as aliastouser This is the only line in test.email. Here is the vacation filter: if true { vacation :days 1 :addresses ["user(a)my.domain.com"] text: Please ignore this message, I am only testing vacation filter . ; } /var/log/mail.log shows that sieve vacation sends vacation, (and after succeeding attempts, discards due to already sent address) Apr 9 13:37:21 mx01 dovecot: lda(user): sieve: <test3>: sent vacation response to <john(a)somewhere.com> Apr 9 13:37:21 mx01 dovecot: lda(user): sieve: msgid=<test3>: stored mail into mailbox 'INBOX' ... Apr 9 13:40:15 mx01 dovecot: lda(user): sieve: msgid=<test3>: discarded duplicate vacation response to <john(a)somewhere.com> Apr 9 13:40:15 mx01 dovecot: lda(user): sieve: msgid=<test3>: stored mail into mailbox 'INBOX' Attached is the doveconf -n output. Any help is appreciated. Milan.

Re: [Dovecot] Heartbleed openssl vulnerability?
by Jake Alley 09 Apr '14

09 Apr '14

It's an interesting issue. In my experience "stale" passwords are rarely used to compromise systems. However, passwords tend to end up on sticky notes and even worse, in email databases regardless. As far as compromised email passwords, they seem to mostly come from infected clients and insecure public logins as far as I can tell. A server can control the later, but not the former. I know of a major accounting software that forces Admin users to change their passwords every few months under certain circumstances. Those passwords always end up in emails to fellow users, so in that case forcing people to change seems to be definitely counterproductive. IMV the moral of the story is that you can't crypt your way into a 100% secure world. You need other forms of checks & reconciliations that are disjoint from purely cryptographic infrastructure. For instance ask Mt. Gox and Bitcoin if they agree in hindsight, and Heartbleed is a very good example of this concept. Thanks, Jake On 4/9/2014 10:27 AM, Reindl Harald wrote: "change passwords from time to time is always clever" is a strawmans argument with no context to the issue, forcing people to change their passwords all the time for no good reasons leads mostly to completly insecured passwords to remember them easier or have them on a sticky on the screen or under the keyboard the word "counterproductive" describes that policies perfectly

[Dovecot] Migration to Dovecot 2.2.12 - How to trigger full site indexing
by kadafax＠gmail.com 09 Apr '14

Hi list, We are in the process of migrating our old (dovecot 1.2.4 based) mail system to the new one: - Centos 6 x86_64 - Dovecot 2.2.12 - Users in an openldap directory - clucene FTS I'm trying to trigger a full indexing for all the user and all their mailboxes (avoiding them to individually trigger it using a search within their MUA). I'm trying to use the "doveadm index" command. First question, is there some sort of 'wildcard' option for the name of the mailbox to index, as I dont know all the mailboxes's names the users have created (beside the regular Sent Inbox Trash and Drafts ? Second question I've tried: # doveadm -D index -A Sent which gave me: doveadm(root): Error: User listing returned failure doveadm: Error: Failed to iterate through some users Can the '-A' option work with ldap backend ?

[Dovecot] Dovecot LDAP issue

Unfortunately, when I try to send e-mail from a user who's not in the testou container I get the following error: Sender address rejected: User unknown in virtual mailbox table> #SMTP#. I'm assuming this happens because dovecot is not able to to lookup up that user since that user is outside the testou container. A lot of the AD users are in different places inside the AD structure and I need to be able to configure dovecot to look from the root of the AD structure down. I changed the base to this: base = dc=domain,dc=tld but it simply fails to lookup any users at that point. How would I go about getting dovecot to start at the top of the domain and look at every nested OU within AD? thanks a lot D

[Dovecot] Debugging doveadm expunge
by Andy Hawkins 08 Apr '14

08 Apr '14

Hi, I'm a recent convert to dovecot, and in general it is all working fine. However, I have a number of cron jobs set up to purge old messages from mailboxes. These don't seem to be doing what I would expect. Is there any way of debugging this process? Some way of seeing what messages it's checking, and why each one matches or fails to match? For example, I'm running this: doveadm expunge -u andy mailbox "News Reports" savedbefore 90d from the crontab of user 'andy'. I'd expect the specified folder to only contain 90 messages (I get one 'News Report' per day) but in actual fact there are 1428 in there! Any advice would be appreciated. Thanks Andy

[Dovecot] dsync replication questions
by Nikolaos Milas 07 Apr '14

07 Apr '14

I am running two servers with Dovecot v2.2.12 on CentOS x86_64 (5.10 and 6.5 respectively) and users are virtual over ldap. I have setup our main internal server (vmail.example.com) with dsync replication according to the first part of http://wiki2.dovecot.org/Replication. The second one (vmail1.example.com) will be the failover server which we want to be a real-time mirror (but can be manipulated directly and it should propagate changes back to vmail.example.com) When I started the server (vmail.example.com) mirroring started and completed fine (after a few hours). However, since then, I am not seeing a continued mirroring between the two. I would expect changes to one of the masters to be propagated in real time to the other - which does not happen. If I manually run (on vmail.example.com) dsync -u imaptester mirror ssh -l root vmail1.example.com dsync -u imaptester then these two accounts are synced. Question 1: Shouldn't mirroring continue automatically in real time (having configured it as in the first part of http://wiki2.dovecot.org/Replication)? If not, what should I do to enable such a real-time (or near-real-time) sync? Note that I have not configured "replication_dsync_parameters" as noted at the above page. Question 2: Where can I find documentation about "replication_dsync_parameters" and about "the doveadm sync command" (referred to at the same page)? I have not been able to locate such a documentation/wiki page. Question 2a: What do options "-d -N -l 30 -U" signify in "replication_dsync_parameters = -d -N -l 30 -U"? Thanks, Nick

[Dovecot] Dovecot IMAP Authentication issue with Vpopmail

Hello All, i've configured a qmail server (for office) under Ubuntu 12.04 server following this guide- http://www.connor.net.au/tutorials/qmail/qmaillite/ everything working just fine except dovecot IMAP. i've followed this section for dovecot- http://www.connor.net.au/tutorials/q...te/dovecot.php<http://www.connor.net.au/tutorials/qmail/qmaillite/dovecot.php> but when i go to telnet 143 and try to login with username/password, it failed and showing error: ** BYE Internal error occurred. Refer to server log for more information.Connection closed by foreign host.* i think there may be some authentication issue with vpopmail and dovecot. POP and SMTP both working. but why not IMAP? i can't also use webmail (i.e. squirrelmail) as it don't working with IMAP. it's showing- *connection dropped by IMAP server *error while trying to login. i'm looking forward to a solution here. any qmail+vpopmail expert here? plz help.

[Dovecot] mdbox with mail_attachment_dir per user in 2.2.12
by Pavel Stano 04 Apr '14

04 Apr '14

Hello, we have 2 netapp arrays with 2 volumes and we need to store our mail data in one or other volume for every user. We want keep data for one user in one volume only. So we would like to have 2 separate mail_attachment_dir, one on every volume. But in latest version 2.2.12 it look like it is only possible to set one global mail_attachment_dir. I have an idea with 2 separate dovecot instances per machine with different mail_attachment_dir. Or it is possible to somehow specify it per user ?

[Dovecot] imap / IPv6 problems?
by Egbert 04 Apr '14

04 Apr '14

Hi, I have this intermittant problem. When sending an email it *sometimes* takes ages before the process finishes. The process seems to hang in moving the message to the sent items" folder". When I disable the IPv6 stack in the network config (this is MS Windows 7), the hanging process immedialetely completes! This makens me think that is has to do with the IP stacks. Another observed effect is a long "rotating wheel" when just klicking on an imap folder before the listing in the right pane updates. Here the same trick solves the problem. I use Thunderbird on W7 as client and have my mail (3 accounts) on a remote mailserver. I have full control over that server which can become handy... Th emailserver is Ubuntu 12.04 LTS with postfix and Dovecot (2.0.19) from the standard repo's. My IPv6 connections is a native IPv6 from my ISP (xs4all.nl). I have no reason to think that the IPv 6 connecition itself is the problem. Any advise to investigate this problem is welcome. Egbert Jan, NL

[Dovecot] xz compression
by T.B. 04 Apr '14

04 Apr '14

Hello Timo, I've successfully setup xz compression for my Dovecot installation using the version 2.2.12 from Debian unstable. Together with the activation of the "Single Instance Attachment Storage", this reduced the mail storage utilization for 20 mail accounts by 74%. *My question:* (For this test just one user was logged in. OS = Debian Wheezy, AMD64) After conversion of my mail storage, IMAP read by Thunderbird worked perfectly. But IMAP write and LMTP write was not possible.* *xz compression seems to need a higher vsz_limit than its default value of 256M without compression. Before the conversion, 256M was enough with the plugins "**acl fts fts_solr" and " imap_zlib". 512M was still not enough for xz compression, 1024M works OK but I'm not sure since this is a relative large increase. My new setting: /etc/dovecot/conf.d/10-master.conf: service imap { vsz_limit=1024M } The absolute minimum to successfully send an empty mail is 710MB (700MB still produces out of memory)! _*Is this normal behaviour? What is a recommended value for "service imap {vsz_limit = }"?*_ I recommend to add this "_vsz_limit"_-increase to the wiki (http://wiki2.dovecot.org/Plugins/Zlib) to make others life easier. Error log below. * **My config & how I converted:* /etc/dovecot/conf.d/10-mail.conf: mail_plugins = *zlib *acl fts fts_solr /etc/dovecot/conf.d/90-plugin.conf: # Enable these only if you want compression while saving: zlib_save_level = 9 # 1..9 zlib_save = xz For "Single Instance Attachment Storage": /etc/dovecot/conf.d/10-mail.conf: # Directory root where to store mail attachments. Disabled, if empty. mail_attachment_dir = /srv/vmail/mail_attachments For compressed IMAP access ( to reduce the bandwidth usage of IMAP ) (has nothing to do with storage space): /etc/dovecot/conf.d/20-imap.conf: protocol imap { mail_plugins = $mail_plugins *imap_zlib* } Previous storage format was standard mdbox Format. To convert a single user, I used dsync from the command line: dsync -u user(a)domain.de mirror mdbox:/srv/converted_vmail/user@domain.de/ After conversion (~2 hours per account), I moved the original mail folder of the user to a backup location and replaced it by the converted folders from "/srv/converted_vmail/user(a)domain.de/". (Pay attention that the directory structure matches!, I had to adjust ist.) *My Problem:* *After conversion IMAP read by Thunderbird worked perfectly**.

[Dovecot] Use 1 userdb and LDAP passdb for mailbox without allow_all_users

You could create MEMORY indices e.g. mail_location = maildir:~/Maildir:INDEX=MEMORY which will allow all the other processing like sieve to work. However, I would look at the cause of the "insufficient privileges": it is a symptom of something that could lead to other problems. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] dovecot 2.2.10 & fts_lucene: Failed to initialize backend

Hey there. (Lesson to self: Don't try to be cute. Somehow a trademark sign breaks my setup and the rest of the mail is discarded? Sorry for the previous, incomplete post) Lurking most of the time here, currently I'm trying to make FTS work. As far as I understand [1], squat is deprecated, solr is a rather big dependency for my 'friends & family' type of installation: Lucene it is! My problem: The lucene backend isn't working, I get this error whenever I try to access it (be it doveadm fts or a search, triggering an index): # doveadm fts rescan -u dar(a)darklajid.de doveadm(dar(a)darklajid.de): Error: fts: Failed to initialize backend 'lucene': Unknown backend doveadm(dar(a)darklajid.de): Error: fts not enabled for user's namespace (null) Any ideas what I might be doing wrong here?

[Dovecot] Disable maildir indexing and dovecot-uidlist on LMTP/LDA delivery
by Jouko Nikula 03 Apr '14

03 Apr '14

Hello all, Is there a way to use LMTP (or LDA) so that maildir index and dovecot-uidlist are not updated? My setup is such that mail delivery sees user's maildir as write only. This setup works well when using postfix for mail delivery, but when I try to switch to dovecot LMTP the lmtp process wants to read the dovecot-uidlist and fails on insufficient privileges. Is there a way around this without exposing the maildir and mail home for read access? Regards, Jouko Nikula

[Dovecot] nfs flush/fsync config settings problem
by Troton_admin 03 Apr '14

03 Apr '14

Hi, I need to place a maildir storage on a NFS filesystem, so I set up the config like this: mmap_disable = yes mail_nfs_storage = yes mail_nfs_index = yes mail_fsync = always lock_method = dotlock (also tried fcntl - local lockd is running, no success, now using dotlock, to be sure while debugging) The problem is that Dovecot (2.2.9/2.2.10 - the relevant code in mail-index.c is the same) logs a fatal error and quits the session (no daemon crash/coredump). Jan 07 14:13:31 auth: Debug: client in: AUTH 1 PLAIN service=pop3 session=fRCRJGHvbADDUKU9 lip=192.168.100.102 rip=IP_ADDR lport=1110 rport=48236 resp=AHRyb3RvbjEAdHJvdG9uMQ== (previous base64 data may contain sensitive data) Jan 07 14:13:31 auth: Debug: passwd-file(troton1,IP_ADDR,<fRCRJGHvbADDUKU9>): lookup: user=troton1 file=/usr/local/etc/dovecot/passwd-file Jan 07 14:13:31 auth: Debug: client passdb out: OK 1 user=troton1 Jan 07 14:13:31 auth: Debug: master in: REQUEST 1289355265 29049 1 4f9fdd9e4069fa503e8e6bcc09d4cf30 session_pid=29089 Jan 07 14:13:31 auth: Debug: passwd-file(troton1,IP_ADDR,<fRCRJGHvbADDUKU9>): lookup: user=troton1 file=/usr/local/etc/dovecot/passwd-file Jan 07 14:13:31 auth: Debug: master userdb out: USER 1289355265 troton1 uid=81 gid=81 home=/home/troton1 mail=maildir:~/Maildir Jan 07 14:13:31 pop3-login: Info: Login: user=<troton1>, method=PLAIN, rip=IP_ADDR, lip=192.168.100.102, mpid=29089, session=<fRCRJGHvbADDUKU9> Jan 07 14:13:31 pop3: Debug: Added userdb setting: mail=maildir:~/Maildir Jan 07 14:13:31 pop3(troton1): Debug: Effective uid=81, gid=81, home=/home/troton1 Jan 07 14:13:31 pop3(troton1): Debug: Namespace inbox: type=private, prefix=, sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/Maildir Jan 07 14:13:31 pop3(troton1): Debug: maildir++: root=/home/troton1/Maildir, index=, indexpvt=, control=, inbox=/home/troton1/Maildir, alt= Jan 07 14:13:31 pop3(troton1): Info: DEBUG1: fsync_mode=2 , mask=0 Jan 07 14:13:31 pop3(troton1): Info: DEBUG2: fsync_mode=2 flags=85 Jan 07 14:13:31 pop3(troton1): Debug: Namespace : Using permissions from /home/troton1/Maildir: mode=0700 gid=default Jan 07 14:13:31 pop3(troton1): Info: DEBUG2: fsync_mode=0 flags=85 The user/passdb is just a plaintext file, for debugging purposes. But what is strange, the messages system log shows: Jan 7 14:13:31 mailhub2 dovecot: pop3(troton1): Fatal: nfs flush requires mail_fsync=always That is obviously wrong, even its own doveconf -n utility shows the correct value. # doveconf -n | grep -E 'sync|nfs' mail_fsync = always mail_nfs_index = yes mail_nfs_storage = yes maildir_very_dirty_syncs = yes Affected code seems to be in the lib-index/mail-index.c file, mail_index_file function - around line 585 : // my custom debug line i_info("DEBUG2: fsync_mode=%u flags=%u", (unsigned int)(index->fsync_mode),(unsigned int)flags); if ((flags & MAIL_INDEX_OPEN_FLAG_NFS_FLUSH) != 0 && index->fsync_mode != FSYNC_MODE_ALWAYS) i_fatal("nfs flush requires mail_fsync=always"); The first time it sees fsync_mode=2 (which is correct value of FSYNC_MODE_ALWAYS), but next function call is with index->fsync_mode=0 and an error is raised, see the logfile above.

[Dovecot] Is replication broken?
by IT geek 31 03 Apr '14

03 Apr '14

Hi, Apologies for this being my 248th post about replication... The current error I'm getting is: Jan 30 12:10:54 Server1 dovecot: dsync-local(MailUser1): Error: dsync( Server2.test.com) read() failed: read((fd)) failed: Connection reset by peer Subsequent errors are: Jan 30 12:15:47 Server1 dovecot: dsync-local(MailUser1): Error: read( Server2.test.com) failed: EOF The above error is seen on Server1, after the initial sync completes of the first mailbox (Sent folder to be precise). Does anyone have an ideas as to what might be causing it? These are brand new rebuilds, running the latest build - I just can't seem to get this working. Bug maybe? Configs are as follows: Server1: # 2.2.10: /usr/pkg/etc/dovecot/dovecot.conf # OS: NetBSD 5.2 cobalt auth_mechanisms = plain login doveadm_password = secret doveadm_port = 12345 first_valid_uid = 1003 last_valid_uid = 1020 listen = 192.168.1.1 login_greeting = test.com mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_plugins = " notify replication" passdb { driver = passwd } plugin { mail_replica = tcp:Server2.test.com } protocols = imap service aggregator { fifo_listener replication-notify-fifo { mode = 0666 } unix_listener replication-notify { mode = 0600 } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = root } service imap-login { inet_listener imap { port = 0 } } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0600 } } ssl_cert = </etc/openssl/certs/Server1.test.crt ssl_key = </etc/openssl/private/Server1.test.key userdb { driver = passwd } protocol lda { postmaster_address = postmaster(a)test.com } ServerB: # 2.2.10: /usr/pkg/etc/dovecot/dovecot.conf # OS: NetBSD 5.1 cobalt auth_mechanisms = plain login doveadm_password = secret doveadm_port = 12345 listen = 192.168.1.2 login_greeting = test.com mail_location = mbox:~/mail:INBOX=/var/mail/%u passdb { driver = passwd } protocols = imap service aggregator { fifo_listener replication-notify-fifo { mode = 0666 } unix_listener replication-notify { mode = 0600 } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } user = root } service doveadm { inet_listener { port = 12345 } } service imap-login { inet_listener imap { port = 0 } } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0600 } } ssl_cert = </etc/openssl/certs/Server2.test.com.crt ssl_key = </etc/openssl/private/Server2.test.com.key userdb { driver = passwd } protocol lda { postmaster_address = postmaster(a)test.com }

[Dovecot] Test outgoing email on director setup
by Murray Trainer 03 Apr '14

03 Apr '14

HI All, I have a several Exim MTA's relaying mail to a pair of director proxies via LMTP which then relayi to several mailstores via LMTP Incoming mail is working fine. My outgoing mail uses LMTP also in the reverse of above. How do I manually test outgoing mail on the mailstores and proxies as I only have dovecot and not exim installed on them? I have the following set in dovecot.conf for LMTP submission_host = mailproxy01:24 mailproxy02:24 Hopefully that works with multiple submission hosts to give redundancy? Thanks Murray

[Dovecot] Info on Config Sharing or Unfied Config?
by Jeffrey Walton 02 Apr '14

02 Apr '14

Is there a wiki page or other resource on configuration sharing between Postfix and Dovecot? Or is there a unified config file somewhere that I can use for mail components (like Postfix, Dovecot, Clam, and Spam Assassin)? I'm finding that I need to add the same information in multiple places. For example, Postfix users go in /etc/postif/vmailboxes, but Dovecot uses a user/password database stored in /var/mail/%d/%u (or other methods). And the same certificates and keys get entered multiple times. I think (or hope) there's something better, but I have not come across the resource.

[Dovecot] Book on Postfix/Dovecot or Postfix/Dovecot/Clam/Spam Assassin?
by Jeffrey Walton 01 Apr '14

01 Apr '14

I'm looking for a book on Postfix/Dovecot or Postfix/Dovecot/Clam/Spam Assassin The blog posts and the mini-HowTo's I am reading lack the detail to be useful to me (due to my own ignorance). Amazon does not list any books for sale. There are some hits when searching for Dovecot, but I expect them to be one section with the quality of a blog post or mini-HowTo. (I have two books on Red Hat and Fedora administration, and the discussions don't meet the quality of a blog post). Does anyone know of a book on Postfix/Dovecot or Postfix/Dovecot/Clam/Spam Assassin? If there are no books with a structured treatment, then O'Reilly is always looking for authors: http://oreilly.com/oreilly/author/intro.csp.

[Dovecot] Deduplicate not processing all messages - bug?
by Jiri Bourek 01 Apr '14

01 Apr '14

Hello, I'm trying to create automated backup recovery using "doveadm import" and "doveadm deduplicate". During testing I noticed that deduplicate only deletes some duplicates and has to be called multiple times to find them all. Here's what I've been trying (in shell commands): First, expunge inbox (the end result is the same even if you delete only some messages): # doveadm expunge -u test mailbox inbox all # ls /home/mailboxes/test/cur | wc -l 0 Then import data from backup - twice, so duplicates are created (again, if you don't delete all messages and call import only once, resulting behaviour is the same.) # doveadm import -u test maildir:/home/test "" mailbox INBOX # doveadm import -u test maildir:/home/test "" mailbox INBOX # ls /home/mailboxes/test/cur | wc -l 1046 Then try to deduplicate # doveadm deduplicate -u test mailbox INBOX # ls /home/mailboxes/test/cur | wc -l 1040 And again # doveadm deduplicate -u test mailbox INBOX # ls /home/mailboxes/test/cur | wc -l 1029 And so on until the message count holds on 523 Each repetition removes 10 - 30 duplicates so eventually all duplicates are removed if "doveadm deduplicate" is called enough times in a row. I also noticed that when I repeat the test, import the backup again and call deduplicate, the steps - how many messages are removed at one time - are the same. That is I start with 1046 messages in the mailbox, after first run there's 1040, then 1029 and so on. My guess would be the behaviour depends on what is stored in the mailbox, but that's pretty much all I can figure out on my own at this time. My question is - is this intended behaviour, ie. are you supposed to run doveadm deduplicate as long as the number of messages in the mailbox keeps changing? Or is it a bug? Tried to Google for the answer but no luck, so thanks for any answers. Tested on Dovecot version 2.2.9 and 2.2.12 (both from Debian repositories.)

[Dovecot] Specifying passwd-file with virtual domains?
by Jeffrey Walton 01 Apr '14

01 Apr '14

I'm trying to use virtual domains and I'm suffering a disconnect. I have two domains - foo.com and bar.com. On the filesystem, they are located at /var/mail/foo.com/ and /var/mail/bar.com/. Users are located at /var/mail/foo.com/john/, /var/mail/bar.com/jane/, etc. There are two password files with <user>:<scheme><password> entries. The scheme is {PLAIN}. They are located at /var/mail/foo.com/users and /var/mail/bar.com/users. According to the wiki, these are passwd-file databases (http://wiki2.dovecot.org/AuthDatabase/PasswdFile) I specified the following in my dovecot.conf. passdb { args = /var/mail/%d/users driver = passwd-file } Attempts to use the configuration result in an authentication failure. Here's an entry from dovecot.log when the failure happens: Mar 31 16:04:12 imap-login: Info: Disconnected (auth failed, 1 attempts in 5 secs): user=<jeff(a)foo.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.1.1, secured, session=<n5/ajez1FgB/AAAB> What exactly goes where to have Dovecot use the 'users' files to authenticate users?

Hi, I'm using dovecot 2.2.5 with quota (maildir backend), zlib and expunge plugins. When I list maildirsize file, I get: 1073741824S 17952 16 If I receive a new message (example: 1204 bytes compressed and 2524 bytes plain text), the quota file is write correctly (2524 1 entry). When I move the message to trash folder (or between user custom folders) the file have wrong entries: 1073741824S 17952 16 2524 1 1204 1 (this is the size of the compressed message) -2524 -1 I coudn't find any relation with the config settings causing this problem and checked the changelog since 2.2.5. Had someone had this same problem? Thanks, Fernando

[Dovecot] pop3 mailbox mirroring issues using dsync
by Nikolaos Milas 30 Mar '14

30 Mar '14

Hello, I have setup v2.2.12 to mirror mailboxes between our main mail server (vmail.example.com) and a failover server (vmail1.example.com) The problem I have is the behavior of mailboxes used on the main server (*vmail*) over POP3. I have setup an IMAP account on the failover server (*vmail1*) on such a mailbox: the mailbox is used on vmail using POP3 and the same is monitored on vmail1 using IMAP. It's mailbox *userx*(in Maildir format). I notice that all mail coming in userx mailbox on vmail, is correctly replicated on vmail1, but when it is downloaded from vmail over POP3 (and the mailbox there remains empty), the same mailbox on vmail1 is not updated to be emptied (automatically) as well, but it is accumulating mail forever (which is real problem on the mirror server). Is there a setting to enable correct mirroring of a POP3 mailbox (to empty the respective mailbox on the failover server) when mail is downloaded from it or something else should be done in this respect? Please explain. I quote below the full current config on the main server. Thanks in advance, Nick ====================================================================== # 2.2.12: dovecot.conf protocols = imap pop3 login_greeting = Org POP/IMAP Srv XAPITI XPICTOY mail_location = maildir:~/Maildir/ mail_gid = 500 mail_uid = 500 auth_mechanisms = plain login auth_username_format = %Lu auth_verbose = yes auth_debug = no disable_plaintext_auth = no mail_plugins = quota notify replication protocol imap { imap_client_workarounds = "delay-newmail" mail_plugins = quota imap_quota notify replication } protocol pop3 { mail_max_userip_connections = 3 mail_plugins = quota notify replication pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } protocol lda { auth_socket_path = /var/run/dovecot/auth-master info_log_path = log_path = mail_plugins = quota notify replication postmaster_address = sysadmin(a)example.com sendmail_path = /usr/lib/sendmail } userdb { args = /etc/dovecot/dovecot-usrdb-ldap.conf driver = ldap } passdb { args = /etc/dovecot/dovecot-passdb-ldap.conf driver = ldap } dsync_remote_cmd = ssh -l root vmail1.example.com doveadm dsync-server -u%u plugin { mail_replica = remote:vmail@vmail1.example.com } plugin { quota = maildir:User quota quota_rule = *:storage=4G quota_rule2 = Trash:storage=+3%% quota_warning = storage=75%% quota-warning 75 %u quota_warning2 = storage=90%% quota-warning 90 %u } service quota-warning { executable = script /opt/mail1.sh user = vmail unix_listener quota-warning { user = vmail } } service aggregator { fifo_listener replication-notify-fifo { user = vmail } unix_listener replication-notify { user = vmail } } service replicator { unix_listener replicator-doveadm { mode = 0600 } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = vmail mode = 0660 user = vmail } user = root } service imap-login { service_count = 1 vsz_limit = 64 M } service pop3-login { service_count = 1 vsz_limit = 64 M } service replicator { process_min_avail = 1 } ssl_ca = </etc/pki/tls/certs/chain-1552.pem ssl_cert = </etc/pki/tls/certs/cert-1552.pem ssl_key = </etc/pki/tls/private/key-1552.pem syslog_facility = local1 ======================================================================

[Dovecot] basic dsync wrapper for migration from another server
by Alan McGinlay 29 Mar '14

29 Mar '14

Hi, I cobbled together this somewhat shoddy Bash script to migrate email accounts from our Cyrus server to a new dovecot system. Feel free to use, or laugh at it as you wish :) #!/bin/bash ## # Migrate email accounts via IMAP from one server to another ## trap "kill 0" SIGINT workdir=/root/migrate # Load list of users into array. The file "migration_map" should contain one user(a)domain.tld per line. mapfile userList < $workdir/migration_map # Number of symultanious migrations num=10 index=0 # Loop over the array of user accounts function process_userlist { procs=$(ps aux | grep "dsync" | grep -v "grep" | wc -l) # Perform $num operations at a time for the length of the userList while [[ $procs -lt $num ]] && [[ ${#userList[@]} -gt $index ]]; do procs=$(ps aux | grep "dsync" | grep -v "grep" | wc -l) dsync -o mail_fsync=never mirror -f -R -u ${userList[$index]} imapc:& echo "procs: $procs user: ${userList[$index]} index: $index" let index++ done } # Until the userList is empty, keep going until [ ${#userList[@]} -eq $index ]; do process_userlist done exit 0

[Dovecot] struggling with dovecot v2.2

Hello all, Long time, no write :-) I am building a spanking, wonderful new mail server. I am very excited about this, since I am going to use the new dovecot v2.2.12 !! However, last time I did this (and documented it), I was working with v1.2. I consulted my notes and it seems there are huge differences between v1.2 and v2.2. So my question is, would anyone know if there's a "quick start" guide for v2.2 ? tia, s.

That's usually the cause of many problems I see with log entries like yours.

The essential difference, as far as your concerned, is that TLS (or STARTTLS or SSLv(some-number-I-forget)) starts out in plain text, then the client issues a command (STARTTLS) to commence the secure (encrypted) communication handshake, whereas SSL dives right in and expects the client to negotiate SSL parameters immediately. These two variations of SSL listen on two distinct ports. If you get these cross up, you'll get the above error log. In my experiments: SSL client -> TLS server port: Aborted login (no auth attempts) TLS client -> SSL server port: client hangs, Disconnected: Inactivity (no auth attempts in 180 secs) SSL/TLS + clear-text password is secure. If you do not use SSL/TLS, you'll have to use CRAM-MD5 or some challenge-response authentication to defeat password snooping. You could use both, but that's overkill.

[Dovecot] Dovecot replication, no updates on message deposit

27 Mar '14

Hi, I am trying to setup dovecot replication based on: http://wiki2.dovecot.org/Replication All mailboxes share the same UNIX userid ('vmail'), and I setup ssh-key based login for this account in both directions. As LDA exim4 is configured to use dovecot deliver LDA. Here is the relevant config from exim: /usr/lib/dovecot/deliver -d $local_part -f $sender_address -a $original_local_part@$original_domain When a message is deposited to a mailbox, it does not get replicated. The log is silent: Mar 25 15:00:20 mx02 dovecot: master: Dovecot v2.2.9 starting up (core dumps disabled) Mar 25 15:01:05 mx02 dovecot: lda(user.name): msgid=unspecified: saved mail to INBOX The output from doveconf -n is attached. Any help is appreciated, Thanks, Milan.

[Dovecot] %{orig_user} missing in checkpassword-Script
by dovecot.pkoch＠dfgh.net 27 Mar '14

27 Mar '14

Hi everybody, I'm using SSL client certificates or checkpassword scripts to authenticate our users. If a user sent a client certificate from his smartcard my checkpasswort will ignore the password, if he does not sent a client certificate but uses his OTP-token then my checkwassword script will check wether the password is a correct one time password. My problem is: the AUTH_USER variable will either contain the username that was configured in the mailclient (if auth_ssl_username_from_cert=false) or the username from the certificate (if auth_ssl_username_from_cert=true). I would like to compare both values, i.e. the %{user} Dovecot-variable and the %{orig_user} Dovecot-variable. But the environment of a checkpassword-script has only one of them. Any ideas? I tried to change the source and found the routine where all the AUTH_xxx environment variables are created. But the %{orig_user] variable was empty at that point, so no AUTH_ORIG_USER variable is created. I'm afraight that whenever the %{user}-Variable is replaced by the UID from the client certificate (due to auth_ssl_username_from_cert=true), the original value of %{user} is NOT copied into %{orig_user} Can someone more familiar with the dovecot source check this please or give me a hint where to look further Kind regards Peter Koch

Re: [Dovecot] IMAP proxy with master user and CRAM-MD5 auth mechanism
by ML mail 26 Mar '14

26 Mar '14

Hi Trent, Thanks for your exhaustive explanation now it is clear. What was unclear to me was the fact that the IMAP proxy server has to take care of the authentication in this case of using a master user and therefore it needs access to the passwords (in my case stored in the mailbox table in PostgreSQL). I still have two open questions: 1) Do I really need the userdb on my IMAP proxy config as you mention in your mail? In my understanding the passdb should be enough (which in my case will use a SQL query joining the result of my proxy and mailbox tables). 2) Is this correct that the IMAP backend (the mailbox server) in this case scenario has to use PLAIN authentication and can NOT use CRAM-MD5? Regards,ML

[Dovecot] IMAP proxy with master user and CRAM-MD5 auth mechanism
by ML mail 26 Mar '14

26 Mar '14

Hello, I would like to know if it possible to have a dovecot IMAP proxy frontend where CRAM-MD5 can be used as auth mechanism (assuming I would be using a master user/password on the dovecot IMAP backend/mailbox)? I have read a few times the following http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy page but somehow it is still unclear to me if the IMAP proxy then needs to have all the users and passwords in its proxy table in the database? Unfortunately there are no examples for that case. Also with this case scenario is it possible to store the users' passwords in CRAM-MD5 format? Any pointers or documentation to such a scenario would be great. Thanks and regards M.L.

[Dovecot] Trying to get Centos5 set up with dovecot
by DCA 26 Mar '14

26 Mar '14

Greetings, It seems I'm having some trouble getting this message into the list. I have used this dovecot list before. I am trying to set up dovecot to replace an older POP3 server in an existing set up. Currently the server uses sendmail to handle incoming mail. users are in /etc/mail and their incoming eMail lands in the /var/mail/username in /var/mail the username file is owned by username:mail I have dovecot configured to create the imap folders in /home/username/mail/ on existing accounts login attempts fail with errors such as: chown /home/username/mail/.imap/INBOX failed: Operation not permitted egid=500(username), group based on /var/mail/username mkdir /home/username/mail/imap/INBOX failed: Operation not permitted. Everything seems to work as expected but only if I add "username" into the "mail" group OR if I have all mailboxes chowned to username:username Is there any way to tell dovecot to ignore the group ownership of /var/mail/username and focus instead on using username:username for everything in /home/username ? If I have to add every user to the mail group I can but this seems messy. Thanks!

[Dovecot] Direct groups of users to pairs of backend servers
by Murray Trainer 25 Mar '14

25 Mar '14

Hi All, I am using dovecot in the Director setup with multiple proxy and backend mailstores and user information stored in LDAP. I am aware users can be directed to a single backend server. It would be useful to be able to direct groups of users to pairs of backend servers to give some fault tolerance against NFS issues and make the whole thing more scalable. Otherwise each backend mailstore will need all the NFS mounts and the whole cluster will be affected if one NFS mount has an issue. I am not sure if this possible with the current dovecot implementation? If not it would be a great enhancement. Thanks Murray

[Dovecot] pb with setting quota_rule=backend quota=fs for quota-warning
by marion 25 Mar '14

25 Mar '14

Hello my config is debian wheezy with dovecot v.2.1.17-2., plugin quota /imap_quota is ok : I can read the real filesystem user quota for each different user with - doveadmin quota get - thunderbird - SOGo my problem is to configure quota-warning message : 1) if no quota_rule is defined then my dovecot-debug.log looks like Mar 25 18:28:02 imap(testuser): Debug:Quota warning: bytes=0 (80%) messages=0 ... 2) As soon as I set quota_rule = *:storage=1G , quota root is correctly defined, and quota-warning messages are sent according to the ratio I defined (cf below 90-quota.conf) with THIS limit (1G) , the same for all users and that’s not what I expect when I set individual quota... 3)And If define something like: quota_rule = * : backend (or backend=%q or …) dovecot definitively hangs with a) doveadm quota get -u testuser doveadm(testuser): Error: user testuser: Initialization failed: Failed to initialize quota: Invalid quota root quota: Invalid rule *:backend: Unknown rule limit name: backend b) even my login in SOGo hangs /var/mail/mail.err Mar 25 21:56:22 biwa dovecot: imap(testuser): Error: user testuser: Initialization failed: Failed to initialize quota: Invalid quota root quota: Invalid rule *:backend: Unknown rule limit name: backend Is there a way ( a variable ?) to link the real filesystem quota limit with the quota_warning process ? … something like quota_rule = *:storage=%VAR ? 90-quota.conf ------------------- plugin { quota_warning = storage=80%% quota-warning 80 %u quota_warning2 = storage=90%% quota-warning 90 %u } plugin { quota =fs } service quota-warning { executable = script /etc/dovecot/myconfig/quota-warning.sh unix_listener quota-warning { mode =0666 } } Thank you in advance best regards, Philippe ______________ Philippe Marion

[Dovecot] Getting second quota limit out of database
by dev＠stean.ch 25 Mar '14

25 Mar '14

Hello there, I am working with dovecot v2.2.12, and have setup a user and domain quota by using a quota/quota_rule for user and quota2/quota2_rule for the domain. This works fine when the limit configuration for both is stored inside dovecot configuration files. However, I would like to have the limits configurable on a user and domain base, and that data is stored inside my SQL database. Getting the user quota out of a database with SQL works fine, as documented with "SELECT whatever AS quota_rule FROM mytable", I extended my query to return quota2_rule too, but dovecot did not really do something with that value in the end, the domain limit was set to 0, as visible through the logs and with doveadm quota get ... Any idea or hint how I could get dovecot to read the limit for the domains out of my SQL database ? Thanks, Stephan

[Dovecot] mail-filter cannot work with large email about 700k
by boyd yang 25 Mar '14

25 Mar '14

Hi All I configured dovecot 2.1.7 with mail-filter plugin. It works well for small emails like server k big.(7k) But it failed with larger emails about 700k. The scripts hang out, and the mail-filter-out process does not exist and always in ps. It does not work even I use "cat" in mail-filter-out.sh. Where to set the size limit for mail-filter? Do you know how to fix this? This bug also exists in 2.2.12. Thanks!

I have (user) sieve filter in my home dir. This filter uses "vnd.dovecot.filter" extension to call some shell scripts. These scrips creates some temporary files. Strange thing: whent sieve is called via dovecot-lda - these files are created by user "kjonca" when sieve is called via lmtp - these files are created by root. Is there any way to drop privilleges where lmtp passing messages to sieve? KJ -- http://wolnelektury.pl/wesprzyj/teraz/

Hi guys, we use dovecot 2.0.9 and authentication against a mysql database. Everything works fine, but we found some weird behavior when the password is e.g. testpass you also authenticate successfully with testpass123 or testpassNOT. Whatever comes after the correct password doesnt matter, the authentication is still successful. Here are the used configs: // auth-sql.conf.ext passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } userdb { driver = static args = uid=vmail gid=vmail home=/data/mail/%d/%n } // dovecot-sql.conf.ext driver = mysql connect = host=[IP] dbname=[DB] user=[USER] password=[PASS] default_pass_scheme = CRYPT password_query = SELECT `password`, `login` AS `user` FROM `v_email_accounts` WHERE `login`='%u' // 10-auth.conf disable_plaintext_auth = no auth_mechanisms = plain !include auth-sql.conf.ext // 10-master.conf default_process_limit = 1000 default_client_limit = 3003 default_vsz_limit = 1024M service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } service_count = 0 vsz_limit = 1024M } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service lmtp { unix_listener lmtp { } } service imap { vsz_limit = 1024M process_limit = 2048 } service pop3 { process_limit = 2048 } service auth { unix_listener auth-userdb { user = vmail group = vmail } client_limit = 8096 } service auth-worker { } service dict { unix_listener dict { } } Thanks in advance for your help!

[Dovecot] imap: Error: mmap() failed with file ... dovecot.index.cache: Cannot allocate memory
by Urban Loesch 24 Mar '14

Hi, since some days (about 10) I get the following error in mail error log many, many times: ... dovecot: imap(user(a)domain.com pid:32769 session:<dszL7lX1xADD/uGI>): Error: mmap() failed with file /home/dovecotindex/domain.com/user/mailboxes/Trash /dovecot.index.cache: Cannot allocate memory .... It's always the same "dovecot.index.cache" file and only for the same heavily used account. The account is currently used from about 10 different clients with imap at the sime time. I checked the size of the index cache file and it seems very big: total 2,7G -rw------- 1 mailstore mailstore 464 Mär 24 14:36 dovecot.index -rw------- 1 mailstore mailstore 464 Mär 24 14:36 dovecot.index.backup -rw------- 1 mailstore mailstore 2,7G Mär 24 14:19 dovecot.index.cache -rw------- 1 mailstore mailstore 140 Mär 24 14:45 dovecot.index.log -rw------- 1 mailstore mailstore 89K Mär 24 14:36 dovecot.index.log.2 About 2,7 GB? To solve the problem temporarily, I removed the index files from the index Trash folder and Dovecot initialized an index rebuild. Now the size of the index files are small: total 28K -rw------- 1 mailstore mailstore 512 Mär 24 14:47 dovecot.index -rw------- 1 mailstore mailstore 20K Mär 24 15:28 dovecot.index.cache -rw------- 1 mailstore mailstore 1,2K Mär 24 15:28 dovecot.index.log But why could the index cache file be so big?

[Dovecot] Dovecot/Django authentication
by Thomas Johnson 24 Mar '14

24 Mar '14

We've got an application in django that has passwords stored in both sha1 and pbkdf2_sha256 form. We need dovecot to be able to authenticate against the django database (we can't modify django to store passwords in dovecot's form, I'm afraid). Has anyone done a dovecot authentication plugin to support these password forms (and/or any other forms that django supports)? Thanks- Tom

[Dovecot] Case-sensitive INBOX or client issue?
by SB Code Ninja 24 Mar '14

24 Mar '14

I am using dovecot as an IMAP server for a Cisco product (Cisco Agent Desktop by Calabrio) and noticed some odd behavior when trying to access emails. The mail is delivered to the main INBOX, then a Cisco server moves it to a directory within the INBOX based on the queue it is meant for. Here is the directory structure of the Maildir: Maildir/INBOX Maildir/INBOX/tmp Maildir/INBOX/63 Maildir/INBOX/63/tmp Maildir/INBOX/63/dovecot.index.cache Maildir/INBOX/63/cur Maildir/INBOX/63/cur/1395445673.M548066P32100.uc-util,S=6403:2, Maildir/INBOX/63/dovecot.index.log Maildir/INBOX/63/dovecot-uidlist Maildir/INBOX/63/maildirfolder Maildir/INBOX/63/new Maildir/INBOX/dovecot.index.cache Maildir/INBOX/cur Maildir/INBOX/dovecot.index.log Maildir/INBOX/dovecot-uidlist Maildir/INBOX/62 Maildir/INBOX/62/tmp Maildir/INBOX/62/dovecot.index.cache Maildir/INBOX/62/cur Maildir/INBOX/62/cur/1395445491.M591207P32114.uc-util,S=6380:2, Maildir/INBOX/62/dovecot.index.log Maildir/INBOX/62/dovecot-uidlist Maildir/INBOX/62/maildirfolder Maildir/INBOX/62/new Maildir/INBOX/new Email is delivered to INBOX then gets moved to INBOX/62 or INBOX/63. The desktop software is then supposed to read the email and process it. I did a packet capture of the conversation and saw the following: IMAP Response: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN] Dovecot ready. IMAP Request: A0 AUTHENTICATE PLAIN IMAP Response: + IMAP Request: <redacted> IMAP Response: A0 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS] Logged in IMAP Request: A1 LIST "" Inbox/63 IMAP Response: A1 OK List completed.

[Dovecot] dsync in a cronjob to replace offlineimap
by Guilhem Moulin 24 Mar '14

24 Mar '14

Hi list, Replacing offlineimap with dsync for IMAP-to-IMAP synchronization (using dovecot 2.1.7) is working great, but now that I upgraded to 2.2.9 I'd like to take advantage of the incremental replication [1]. I don't think having a separate replicator process & notifications suits my configuration, as I want to sync my server with my laptop which is not always on or might be behind a firewall. After reading ‘replication/replicator/dsync-client.c’ I was thinking of writing a small wrapper around dsync performing a daily full replication and updating the state otherwise. The following works great in a cronjob doveadm sync -l30 imap.example.org but when I try to get the current state doveadm sync -l30 -fs '' imap.example.org >~/mail/dsync.state and later use incremental replication state=$(< ~/mail/dsync.state) doveadm sync -l30 -s "$state" imap.example.org >~/mail/dsync.state the state seems to somehow quickly become "stale" and messages stop being retrieved from the server. I understand that dsync's incremental replication is mostly intended to be used by the replicator process, but I'm wondering whether it's also possible to use it manually ;-) If so, how to keep a sane state? Thanks, cheers, -- Guilhem. [1] http://wiki2.dovecot.org/Replication

[Dovecot] Debian Wheezy Dovecot Replication no updates on message deposit

21 Mar '14

Hi, I am trying to setup dovecot replication based on: http://wiki2.dovecot.org/Replication http://www.dovecot.org/list/dovecot/2013-January/087674.html I know that 2.1.7 is dated, but I would refrain from upgrading, if not necessary.

Apparently, dsync happens only on periodic updates. If a message is deposited on one server, it will only propagate to the other once a while. Thanks, Milan.

Hello, I'm using Postfix + Dovecot (2.2.6) + roundcube 0.8.x + mysql. The roundcube webserver is hosted on a different server than the Dovecot. The dovecot itself is a replicated 2 node configuration. I would like to allow users to change the password from roundcube interface. All the examples I have seen, assume that roundcube runs in the same server as dovecot. Is there an example / documentation to enable this to work, applying reasonable security measures. -Thanks Vijay

[Dovecot] Password hashing issue
by Daniel Reynolds 20 Mar '14

20 Mar '14

Hello, First off, thanks in advance for all of your help. Now to my issue: I am setting up my first email server. It will be for just me and a few other people. I am using an Amazon EC2 server running Ubuntu 12.04. My MTA is postfix. As I said, this is my first time setting up an email server, so I am following a guide that Arstechnia has published (link<http://arstechnica.com/information-technology/2014/03/taking-e-mail-back-pa…> ). My issue comes when I try to create a hashed of my passwords. I have tried entering the command, "doveadm pw -s SSHA512". When I do this, I get the error message, "doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/99-mail-stack-delivery.conf line 6: Unknown setting: ssl_client_ca_dir". I have tried running that command with sudo and as root, but I still get the exact same error message. I had configured /etc/dovecot/conf.d/99-mail-stack-delivery.conf earlier on, and line 6 of that document says, "ssl_client_ca_dir = /etc/ssl/certs" which is exactly what the ars guide told me it should say. What have I done wrong? Thanks again, Daniel

Re: [Dovecot] versioning of mailbox index files
by morrison 19 Mar '14

19 Mar '14

My current approach is to introduce a index version file .dovecot.index.version in each mailbox and hooks mailbox_allocated event via my own plugin. If the version file does not exist or exist but with version number which need to be upgraded, index files in that mailbox are removed. I also tried to hook mailbox_opened() event and found that event was too late (index was loaded already). The side effect of hooking mailbox_allocated is that the event fires not only by 'select' command. 'list' command can also trigger a lot of mailbox_allocated events. Are there any better hook points I can use for this purpose? Thanks,

[Dovecot] Using a Sieve script to handle delivery to public mailboxes
by Alessandro Menti 19 Mar '14

19 Mar '14

Hello everyone, I'm setting up a Postfix+Dovecot stack with virtual domains and public mailboxes. I set up a shared mailbox "office(a)mydomain.com" as described in the Dovecot Wiki [1], that is: - I created the directory "/var/mail/mydomain.com/public/" and inside it I created the ".office" mailbox; - I added an appropriate ACL to allow the account "president(a)mydomain.com" to read and edit that mailbox under a public namespace; - I added a Sieve script to handle delivery to the public mailbox (its location is /var/mail/mydomain.com/public/.office/.dovecot.sieve). Some other relevant details about my configuration: - The backend used by Postfix and Dovecot to handle virtual aliases/domains/maps is a MySQL database. Since the virtual user table is used by other applications as well, I decided to keep it "clean" and to make use of another "virtual mailboxes" table (see /etc/dovecot/dovecot-sql.conf.ext below). The password_query setting returns only results from the virtual user table (so that only real users can authenticate on the IMAP server), while the user_query setting returns results from both the virtual user and the virtual mailbox table (so that dovecot-lda can choose the correct mailbox). - The queries saved in password_query and user_query return the correct results when executed manually: the home directory for the "office(a)mydomain.com" virtual mailbox is set to /var/mail/mydomain.com /public/.office. - Delivery from and to the "president(a)mydomain.com" account is regular, and that account is able to access the "office(a)mydomain.com" virtual mailbox (I have tested this by speaking IMAP to the server and by performing a manual check using Thunderbird). I encountered a problem with this setup: when I send a message to the "office(a)mydomain.com" account, the Postfix logs say it is correctly delivered via Dovecot, but the Sieve script says it can not find the folder "Public/.office". As a consequence, Dovecot creates a new Maildir in /var/mail/mydomain.com/office and delivers the mail there instead of saving it in the correct directory (/var/mail/mydomain.com/public/.office). Is there something I set incorrectly in my configuration? What is causing Dovecot not to recognize the correct mailbox during delivery? Is there a way to list all mailboxes seen by dovecot-lda itself?

Allowing a sender control over both the recipient (via spoofing), and the content seems like perfect recipe to turn your mail server into a spam relay cannon. If you do do this, you should hedge this by only allowing it from known trusted senders (e.g. local network). Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Dovecot crashes on large search result sets in virtual folders when using fts-solr
by Steffen Templin 19 Mar '14

19 Mar '14

Hi Devs, I experience reproducible crashes when searching in a virtual folder with fts-solr activated. The crashes occur only, if the folder contains a large number of mails and the result set of the search is also large. If the result set is small, no crash occurs. This happens on Debian Wheezy with versions 2.1.7 and 2.2.9. My goal was it to setup the possibility for cross-folder fulltext search. Therefore dovecot was setup with fts-solr, which seems to work fine in most cases. A virtual folder "test" in a namespace "virtual" was created and configured to return all mails from all mailboxes in the default namespace (with empty prefix). It was configured like this: /etc/dovecot/virtual/test/dovecot-virtual: * all It's also reproducible with: INBOX all The test user only has the standard mail folders (Sent, Drafts, Trash) beside the INBOX and of course the folder "virtual.test". INBOX contains about 10.000 mails, the other folders are empty. "virtual.test" correctly referrs to all mails of the INBOX. Searching within the INBOX returns the desired results without any problems. Performing the same search within "virtual.test" fails and dovecot crashes. However, if the result set is small, no crash occurs. My test mails are imported from the ubuntu mailing list. Therefore the term "ubuntu" produces a large result set. See attachments for further details, they all refer to the same crash, reproduced with version 2.2.9 (from the Debian Backports repository): - config.txt: dovecot -n - gdb_backtrace.txt: The gdb backtrace of the attached core dump - log.txt: A logfile extract from the crash - protocol_output.txt: The telnet session that caused the crash Don't hesitate to ask for further details. Thanks and best regards, Steffen

[Dovecot] versioning of mailbox index files
by morrison 18 Mar '14

18 Mar '14

Hi, I am wondering if dovecot assigns version information in mailbox index files so that by which version of dovecot the index files are created can be determined. Our existing mail service used dovecot 2.2.4 with lots of active mail users. When upgraded to 2.2.10, imap processes aborted all the time due to the corrupted index files (the problem was fixed in dovecot 2.2.5). After investigation, I found that this annoying problem could be avoid by deleting index files before opening a mailbox. Now the problem is how I could know if the index files are created by a version newer than 2.2.4. Thanks, Morrison

[Dovecot] FTS solr : body search gives mysql error
by Alexandre Ellert 15 Mar '14

15 Mar '14

Hello, I've recently setup FTS solr plugin, following http://wiki2.dovecot.org/Plugins/FTS/Solr, and I have this error in logs when I do a body search : Mar 13 01:46:40 mut-mx-1 dovecot: auth-worker(5808): Warning: mysql: Query failed, retrying: Unknown column 'disableindexer' in 'where clause' Mar 13 01:46:40 mut-mx-1 dovecot: auth-worker(5808): Error: sql(user(a)domain.com): User query failed: Unknown column 'disableindexer' in 'where clause' Mar 13 01:46:40 mut-mx-1 dovecot: indexer-worker: Error: user user(a)domain.com: Auth USER lookup failed Mar 13 01:46:40 mut-mx-1 dovecot: indexer-worker: Error: User user(a)domain.com lookup failed: Internal error occurred. Refer to server log for more information. Mar 13 01:46:40 mut-mx-1 dovecot: imap(user(a)domain.com): Error: indexer failed to index mailbox INBOX Anyway, the search result seems good. Should I worry about this error or is there other thing I should do (i.e modify mysql schema) ? I'm using mysql as a backend to store users and password. According to the documentation, I just added this block of configuration (please tell me if need full doveconf -n) : mail_plugins = fts fts_solr [ my other plugins ] plugin { fts = solr fts_solr = url=http://127.0.0.1:8080/solr/ } Versions : OS : Debian 7 dovecot : 2.2.12 (from dovecot-ee repo) solr : 3.6.0 (from distrib repo) Other recommendations and feedback about using solr FTS in production would be greatly appreciated. Many thanks. Alexandre

[Dovecot] Strange difference between mails delivered with dovecot-lda and lmtp
by kjonca＠o2.pl 15 Mar '14

15 Mar '14

For a long time I have had configuration where mails were fetched by fetchmail then passed to exim and then passed to dovecot via lmtp. Recently I remove dovecot module and mails are passed from exim to dovecot via dovecot-lda Yesterday I have some kind of accident and lost my .fetchids file so a lot of mails were fetched again. During duplicate hunting I found something strange: messages fetched yesterday (passed to dovecot with lda have additional line) have additional line at the end: for example --8<---------------cut here---------------start------------->8--- diff cur/1392241092.M478532P15313.alfa,S=13668,W=13925:2,a cur/1394814438.M978438P14745.alfa,S=13567,W=13823:2,a 1,6c1,4 < Return-Path: <system(a)przelewy24.pl> < Delivered-To: <kjonca@localhost> < Received: from alfa.kjonca < by alfa.kjonca (Dovecot) with LMTP id p94PDcTp+1LROwAApvcrCQ < for <kjonca@localhost>; Wed, 12 Feb 2014 22:38:12 +0100 < Received: from [127.0.0.1] (port=60632 helo=alfa.kjonca) --- > Return-path: <system(a)przelewy24.pl> > Envelope-to: kjonca@localhost > Delivery-date: Fri, 14 Mar 2014 17:27:18 +0100 > Received: from [127.0.0.1] (port=45527 helo=alfa.kjonca) 9,10c7,8 < id 1WDhVU-0003ys-75 < for kjonca@localhost; Wed, 12 Feb 2014 22:38:12 +0100 --- > id 1WOUgz-00015z-L0 > for kjonca@localhost; Fri, 14 Mar 2014 17:10:41 +0100 13c11 < for <kjonca@localhost> (single-drop); Wed, 12 Feb 2014 22:38:12 +0100 (CET) --- > for <kjonca@localhost> (single-drop); Fri, 14 Mar 2014 17:10:41 +0100 (CET) 30c28 < Message-Id: <E1WDhVU-0003ys-75(a)alfa.kjonca> --- > Message-Id: <E1WOUgz-00015z-L0(a)alfa.kjonca> 256a255 > --8<---------------cut here---------------end--------------->8--- I'm somewhat confused with this.

[Dovecot] Problem with trying to use dsync with ldap userdb
by Frédéric Goudal 14 Mar '14

Hello, I'm trying to use dsync on a dovecot 2.2.12 I'm using an ldap database as a user database with the following configuration : auth_bind = yes ldap_version = 3 auth_bind_userdn = uid=%u,ou=People,dc=ipb,dc=fr user_attrs = uidNumber=uid,gidNumber=gid But I keet having the following errors : 2014-03-14 17:53:37 doveadm(XXX): Debug: user XXX: Auth PASS lookup returned temporary failure: reason=Configured passdbs don't support crentials lookups 2014-03-14 17:53:37 doveadm(XXX): Debug: auth input: reason=Configured passdbs don't support crentials lookups 2014-03-14 17:53:37 doveadm(XXX): Error: sync: /usr/local/var/run/dovecot/auth-userdb: Configured passdbs don't support crentials lookups (to see if user is proxied, because doveadm_port is set) I have been hunting through the doc for the last hours and I don't find what to change. I found something about adding set INSECURE_SETUID=1 export INSECUURE_SETUID before checkpassword-reply launch, but it does not change anything... Btw my two server have use the users uid from the ldap, but don't allow user login on the servers where only admin can log in. Does somebody has an idea where to dig ? f.g.

[Dovecot] NFS not responding generates authantication crash
by bart 14 Mar '14

14 Mar '14

I am facing dovecot authentication problems caused by unresponding NFS server. If there is even short break in communication with NFS server keeping maildirs, the dovecot generates the avalanche of processes (dovecot/imap and dovecot/pop3). The real number of connections was about 50 and after the problems occurs it rises to 1000. After about 3 hours the limit of connections is filled up: dovecot: master: Warning: service(auth): client_limit (1000) reached, client connections are being dropped and next: imap-login: Warning: Auth process not responding, delayed sending greeting pop3-login: Warning: Error sending handshake to auth server: Broken pipe imap-login: Warning: Error sending handshake to auth server: Broken pipe When the mail storage was local there was no such problem. After moving to NFS storage the problem arised when trying to make backup with dump (we switched to rsync then) or now if NFS is not responding for a while. My dovecot conf for NFS is in accordane with: http://wiki2.dovecot.org/NFS mmap_disable = yes dotlock_use_excl = no # only needed with NFSv2, NFSv3+ supports O_EXCL and it's faster mail_fsync = always mail_nfs_storage = no mail_nfs_index = no NFS shares are connected with no special parameters. Can something be done on dovecot configuration to prevent from generating those dovecot connections processes? Or is it the problem with NFS configuration? -- View this message in context: http://dovecot.2317879.n4.nabble.com/NFS-not-responding-generates-authantic… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] quota using wrong limits in user shared mailboxes
by Steffen Kaiser 13 Mar '14

13 Mar '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I have setup a shared namespace to expose user's mailboxes to other users. That works well. Via ACLs users can access other users mailboxes. I have setup a quota for each user, that works well, too. The quota is tracked and new messages are denied, if the quota is exceeded. I do not find hints, if you need to setup something special for shared namespaces. http://wiki2.dovecot.org/Quota/Configuration shows how to track the quota and http://wiki2.dovecot.org/SharedMailboxes/Shared shows how to setup the namespace and ACL. If user1 shares "mailbox" to user2 and user2 copies a message there, the quota is tracked in the quota of user1 correctly. But to calculate if * LOGIN user2 ... * COPY 1 users.user1.mailbox fails with overquota or succeed, the quota limit of user2 is used instead of the quota of user1, whom "mailbox" belongs to. I have tested it with a. limit(user2) < limit(user1) b. quota(user1) + sizeof(message) < limit(user1) if quota(user1) + sizeof(message) > limit(user2), COPY fails with overquota. If I raise the quota of user2, the COPY succeeds. That means, although the target user's quota is not exceeded and won't after the copy, COPY fails. That seems to be wrong for me. The same will apply to the other way round, I guess: If the target user is over quota, but copying user's quota limit is greater than that, the COPY succeeds. [I have not tested it.] Hence, if you enable sharing, you undermine quota, because the other user can copy messages into a mailbox of an user overquota. Does other people see the same issue?

Hi There, Ive taken a look at this and cant quite figure out what is going on here. I have tested all the SQL permissions, and also changed the unix_listener auth-userdb mode to 0666 (as instructed elsewhere to try and solve this issue), but cannot seem to work out what the issue is. Would someone be able to please point me in the correct direction here?

[Dovecot] Turning on autocreate of maildirs - how?
by Graham Leggett 13 Mar '14

13 Mar '14

Hi all, I have a dovecot v2.2.7 installation, and I would like dovecot to autocreate the Maildir mailbox when those mailboxes don't exist. Following the instructions at http://wiki2.dovecot.org/MailboxSettings have had no effect, the errors below are reported. As soon as I create the Maildir manually with maildirmake fetching mail starts working fine, so all of the messages about the directory being ambiguous seem to be a red herring. Anyone know how to turn this on?

[Dovecot] Struggling with antispam
by Alan Chandler 13 Mar '14

13 Mar '14

I have a dovecot installation I am building on a raspberry pi for a mail server for the home. I am almost there, everything bar one thing is working. In simple terms dovecot is the authentication agent and the lda (using lmtp) for postfix. My maildir mailboxed at at /var/mail - location and accounts controlled by a small sqlite database. the uid for these mailboxes are 10001 and up and are not mapped to any account on the system. The sieve plugin is working and I have a default script which works to archive outgoing mail, returned via postfix sender_bcc_maps to user+saveout into a Sent subfolder organised by date. postfix also uses milters, to do spf, and dkim checking - and most importantly from this posts perspective passes all mail through dspam, adding an X-DSPAM-Signature header as it passes through. I plan to use another default sieve script to move mail based on the X-DPAM-Result header to move messages to the users Junk folder (when I can get antispam working). I want to use the antispam plugin to pick up users moving mail in and out of their Junk folder to train dspam. I initially tried using antispam's dspam backend. However I could not get it to work. I "think" the issue is that antispam is running with uid 10001 when it does this, and dspam will not process the message because it can't find this uid as a system user. But I am not sure. The approach I am trying now, is use the pipe backend to send mail to spam(a)chandlerfamily.org.uk or ham(a)chandlerfamily.org.uk - and via postfix manipulations get that to call dspam as user dspam. If I run as root and use sendmail -bv to check that it works I get a delivery report that shows that it would indeed arrive at dspam I have a file in /var/spool/dspam called group which has dpsam:shared:* In it so that all users share the same dictionary. However, when I try to make this work with anitspam, I keep getting failure, and I can't work out what is causing it. Maybe its again because I am running with uid 10001 when calling sendmail but I don't know. antispam config is plugin { antispam_debug_target = syslog antispam_verbose_debug = 1 antispam_backend = pipe antispam_signature = X-DSPAM-Signature antispam_signature_missing = error antispam_trash = Trash antispam_spam = Junk antispam_pipe_program=/usr/bin/sendmail antispam_pipe_program_args=-f;dspam(a)chandlerfamily.org.uk antispam_pipe_program_spam_args=spam(a)chandlerfamily.org.uk antispam_pipe_program_notspam_args=ham(a)chandlerfamily.org.uk } And what appears in syslog as a result of moving a mail from my INBOX to the Junk folder in thunderbird is ...

I would prefer to use dpsam backend directly if someone can tell me how to overcome the dspam rejection issues, but this alternative would also work (if a bit more convoluted to get mail to the correct place) if I could get antispam to call sendmail correctly.

[Dovecot] Disable/patch iOS7 Full Body Search
by Chris Laif 12 Mar '14

12 Mar '14

As mentioned in other posts [1], iOS7 Mail App uses a multi-folder full body search by default. As to my knowledge, this behavior cannot be disabled within the Mail App. Is there any way to disable/patch this behavior on the server side? My users complain that searching now takes 'forever'. They were happy with the old behavior (searching From/To/Subject only). I do NOT want to setup/maintain a dovecot FTS. I just want to have the 'old' behavior. Chris [1 ]http://blog.fastmail.fm/2013/09/17/ios-7-mail-app-uses-multi-folder-body-searches-by-default/ ("Our plan at FastMail is to detect iOS clients, and convert all searches into FUZZY searches.")

[Dovecot] Finding memory leaks
by Philipp Brüll 12 Mar '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I try to find a memory leak in a dovecot plugin that I develop. In order to find it, it would be helpful to print the total amount of memory that is currently allocated. This print could than spread over the source code and the memory consumption can be tracked. I've tried i_debug("pool size %u", (unsigned int)pool_alloconly_get_total_alloc_size(system_pool)); But that failed. Does someone has a good advice? I would like to avoid complex solutions like valgrind.

[Dovecot] Doveadm?

I have a question? Is it possible that with doveadm delete all but the last x-number of messages in a folder. For example to retain the last 200 messages in the folder. If it is possible, how do you do it? Something like "doveadm expunge -u jane.doe(a)example.org mailbox xxx" Thank you! -- //Tommy

[Dovecot] Can I create multiple sockets and listen on them in parallel.
by Alan Chandler 11 Mar '14

11 Mar '14

I currently have a setup which is postfix -> dovecot via lmtp over a unix socket. The socket is located at /var/spool/postfix/private/dovecot-lmtp I am calling dspam as a milter from postfix. However I am struggling with getting dspam knowing the correct user for the incoming mail, because after its been through the milter, the virtual alias maps etc end up turning it into my "dovecot" user name, and the two are not easily comparable. So instead I want to try and set up postfix->dspam->dovecot But I want to take it in easy stages, and therefore ideally would like to set up dovecot to listen on two sockets simultenously = one for the existing connection from postfix, and one for the future connection from dspam - preferably in the context of the /var/spool/dspam or /var/lib/dovecot directories That way I can continue to receive existing mail whilst sending a few test mails through dspam. Does 10-master.conf config file work that way? (debian configuration) can I change something like this ... service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { mode = 0600 group = postfix user = postfix } } into this ... service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { mode = 0600 group = postfix user = postfix } unix_listener /var/spool/dspam/dovecot-lmtp { mode = 0600 group = dspam user = dspam } } and still have dovecot work? -- Alan Chandler http://www.chandlerfamily.org.uk

[Dovecot] POP3 and mail retention
by Roman Gelfand 11 Mar '14

11 Mar '14

Using outlook 2010 as mail client, I have noticed that once an email is moved from inbox, it is deleted from the cur/ directory on the server. Is there a pop3 setting on dovecot that would keep emails, with possible retention period, and recognize that this email has been moved from inbox, etc.. If all of this is doable, would setting outlook to delete the email after 14 days work? delete email from the server when emptying deleted folder? Thanks in advance

by Balamurugan Ramasamy 10 Mar '14

10 Mar '14

Hi All I follwed the steps in the below url to configure a dovecot proxy instance. http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy I created a new file '95-test.conf' in /etc/dovecot/conf.d/ location. and put the below lines in that file. proxy=yes host=**** port=143 nopassword=yes However I am getting the following when starting the serice. I tried 'proxy' and 'proxy_maybe' entries, and they both failed. doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10-auth.conf line 11: Unknown setting: proxy Could anyone help me how i can resolve this? Thanks Bala

[Dovecot] Sieve/autosubscribe subfolder
by Moritz Augsburger 09 Mar '14

09 Mar '14

Hi, I just ran across the annoying issue, that with lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes set, parent folders of newly created subfolders get subscribed without being existent. Let me give an example: In sieve I use fileinto "foo/bar"; but "foo/" does not exist as folder. So the Mailbox "foo/bar" gets created, but without "foo/" being a Mailbox. Nevertheless gets "foo/" subscribed, so that I have a non-existing mailbox in my subscription list, what confuses thunderbird. So, to solve this problem, I would propose - either the implicit creation of foo/ as mailbox or - not subscribing foo/ Moritz

[Dovecot] Mbox corruption - Inbox beginning with 'FFrom' or 'FrFrom'
by Dimos Alevizos 08 Mar '14

08 Mar '14

Hello, we're having some problems with our dovecot setup. I've seen similar problems in the mailing list some years ago but alas wasn't able to find a solution. Our setup is as follows : An MX farm (postfix) sends mails via LMTP to a director farm (dovecot 2.1.12) which proxies pop3/imap/lmtp traffic to a dovecot farm (dovecot 2.1.16). All mailboxes and indexes are on NFS and all servers are Centos. The problem is that at times we see mailboxes (all of them are in mbox format) beginning with FFrom or FrFrom and of course dovecot says it's not a valid mbox file. If we manually remove the offending extra characters from the beginning of the file everything is working again, but often the same user will show the problem again tomorrow. However it's very rare and so far we haven't been able to reproduce the problem. After activating the mail_log plugin hoping it'll help us locate the problem we run across this case : The user (let's call him user(a)domain.gr) logs in via pop3 and deletes some mails but one of them fails: Jun 19 11:09:18 pop01 dovecot: pop3-login: Login: user=<user(a)domain.gr>, method=PLAIN, rip=83.235.173.26, lip=83.235.66.40, mpid=1389, secured, session=<Ao+rWH3fHgBT660a> Jun 19 11:09:18 director5 dovecot: pop3-login: proxy(user(a)domain.gr): started proxying to 83.235.66.40:110: user=<user(a)domain.gr>, method=PLAIN, rip=83.235.173.26, lip=83.235.66.65, session=<Ao+rWH3fHgBT660a> Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20670, msgid=<9f5b1a20a9428ed31a9e7e42ce4411f08d0.20130612070424(a)mail84.us2.rsgsv.net>, size=36526 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20671, msgid=<b27d72dc5a47a3235a232494c6fe8aa0(a)newsletter.stockout.gr>, size=4637 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20672, msgid=<1113670779560.1111910791405.1470.2.32032003(a)scheduler.constantcontact.com>, size=38655 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20673, msgid=<83600a274c1407c5aa4c263e2592cb54(a)debop.gr>, size=1181688 Jun 19 11:09:24 pop01 dovecot: pop3(user(a)domain.gr): expunge: box=INBOX, uid=20674, msgid=<F2A59BE7-007A-4567-9BA5-803446C3D7F8(a)bernier-eliades.gr>, size=61116 Jun 19 11:09:26 pop01 dovecot: pop3(user(a)domain.gr): Error: Next message unexpectedly corrupted in mbox file /var/mail/K/Y/V/domain_gr_user_007 at 1 Jun 19 11:09:26 pop01 dovecot: pop3(user(a)domain.gr): Error: Cached message offset 1 is invalid for mbox file /var/mail/K/Y/V/domain_gr_user_007 Jun 19 11:09:27 pop01 dovecot: pop3(user(a)domain.gr): Disconnected: Logged out top=0/0, retr=2/1502843, del=122/359, size=137448432 Jun 19 11:09:27 pop01 dovecot: pop3(user(a)domain.gr): Warning: Our dotlock file /var/mail/K/Y/V/domain_gr_user_007.lock was deleted (locked 9 secs ago, touched 9 secs ago) Jun 19 11:09:27 pop01 dovecot: pop3(user(a)domain.gr): Error: file_dotlock_delete() failed with mbox file /var/mail/K/Y/V/domain_gr_user_007: No such file or directory Jun 19 11:09:27 director5 dovecot: pop3-login: proxy(user(a)domain.gr): disconnecting 83.235.173.26 (Disconnected by server): user=<user(a)domain.gr>, method=PLAIN, rip=83.235.173.26, lip=83.235.66.65, session=<Ao+rWH3fHgBT660a> However he's still able to log in again : Jun 19 11:11:36 pop01 dovecot: pop3-login: Login: user=<user(a)domain.gr>, method=PLAIN, rip=85.74.231.10, lip=83.235.66.40, mpid=10094, secured, session=<QDLrYH3f7ABVSucK> Jun 19 11:11:36 director3 dovecot: pop3-login: proxy(user(a)domain.gr): started proxying to 83.235.66.40:110: user=<user(a)domain.gr>, method=PLAIN, rip=85.74.231.10, lip=83.235.66.63, session=<QDLrYH3f7ABVSucK> Jun 19 11:11:51 pop01 dovecot: pop3(user(a)domain.gr): Disconnected: Logged out top=0/0, retr=0/0, del=0/237, size=75036938 Jun 19 11:11:51 director3 dovecot: pop3-login: proxy(user(a)domain.gr): disconnecting 85.74.231.10 (Disconnected by server): user=<user(a)domain.gr>, method=PLAIN, rip=85.74.231.10, lip=83.235.66.63, session=<QDLrYH3f7ABVSucK> A few minutes later he receives another mail which is delivered with no problem : Jun 19 11:30:39 corvus amavis[546]: (00546-22) Passed CLEAN, [91.190.168.40] [91.190.168.40] <tk-14439(a)free.splio.com> -> <user(a)domain.gr>, Message-ID: <58175-bWFyaW5hQGJlcm5pZXItZWxpYWR lcy5ncg==(a)free.splio.com>, mail_id: J1P-0WpmQksJ, Hits: 1.412, size: 9025, queued_as: 02BA4AE00414, Tests: [DKIM_VALID=-0.1,DKIM_VERIFIED=-0.1,FREEMAIL_FROM=0.001,HTML_IMAGE_RATIO_04=0.61,INVALID_MSGID=1,URIBL_BLOCKED=0.001], autolearn=disabled, 1533 ms Jun 19 11:30:39 corvus smtp/smtpd[1283]: proxy-accept: END-OF-MESSAGE: 250 2.0.0 from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as 02BA4AE00414;

[Dovecot] Planning migration
by Alan Chandler 08 Mar '14

08 Mar '14

I think I have a working dovecot installation, and the time has come to migrate my users. There are only 4 of us, so it can be done manually per user. I looked at this page in the wiki http://wiki2.dovecot.org/Migration/Dsync but I am totally confused. 1st off, it uses doveadm, but with commands parameters that dont match my doveadm's man page. In fact they look more like dsync parameters. Is there an error, or am I totally misunderstanding 2nd - if I assume its a dsync set of parameters, the imapc: at the end is a specification of location2. However, again my man page doesn't give any explanation of this. I am wondering, is this an example of an proxy 3rd - where do the imapc_* parameters go in the configuration I can't find any reference to them in the wiki

[Dovecot] How to run a program with mail_filter plugin
by Stanislas SABATIER 07 Mar '14

Hi, I'm using mail_filter plugin but I don't want it to launch a script but a program I wrote instead. In 10-master, if I put the absolute path to my program in the plugin settings ie : (…) service mail-filter { executable = /usr/local/bin/mail/my_email_filter (…) But I've got the following error from Dovecot : dovecot: master: Error: service(mail-filter): Initial status notification not received in 30 seconds, killing the process h ow do I need to configure the service to launch my program ?

[Dovecot] no sieve with lmtp_save_to_detail_mailbox=yes
by Dennis Kuhn 06 Mar '14

06 Mar '14

i have a problem with sieve and lmtp_save_to_detail_mailbox = yes. If the mailbox "detail" exists everything works fine, but if the mailbox detail does not exist then sieve does not work. The .dovecot.sieve.log file says sieve: info: started log at Mar 06 14:28:47. error: msgid=<531877EE.7070806(a)heinlein-support.de>: failed to store into mailbox 'test2': Mailbox doesn't exist: test2. I think this is the reason why no sieve script is executed, but why is sieve here involved? Is there any relation between lmtp_save_to_detail_mailbox=yes and sieve or is this a bug? The same sieve file works with the same mailaddress without mailextension, so the sieve script is not the reason for the failure.

[Dovecot] Still no emails since Feb. 6
by Steve Campbell 06 Mar '14

06 Mar '14

I checked my settings on the dovecot mailman page, and although my account was set to "disable" email, after changing it and attempting to have the list resend my password, I'm still not seeing emails. The last time I received emails, the outgoing server for the list was sent from the IP 193.210.130.67. Is that still correct? I've checked my logs to see if there's anything blocked, and I don't see anything. I've checked my access file and firewall, and nothing is blocked there. I'm not sure why my account settings showed "disabled", but it sounds like email was either bounced back to the list or my server is in some type of outgoing list to prevent sending to me. I'm at a loss. Is there any way an admin can check for me, please, to see if there's a problem they might spot? Thanks, steve

[Dovecot] Pigeonhole Sieve Extprograms Plugin
by dovecot＠voidptr.de 06 Mar '14

06 Mar '14

Hi, I upgraded to Dovecot 2.2.9 from Debian's wheezy-backports today (which should contain the "sieve_extprograms" plugin and thus also the vnd.dovecot.{pipe,filter,execute} capabilities. However when I add require "vnd.dovecot.filter"; to my sieve script via managesieve, the server reports error: require command: unknown Sieve capability: 'vnd.dovecot.filter' What am I missing and what should I do to get pipe/filter/execute to work? postconf -n attached.

[Dovecot] whole user mailbox read only
by Francesco 06 Mar '14

06 Mar '14

Hello, i was browsing the dovecot wiki for some documentation related to the use of ACLs but i couldn't find an answer. i'm in the need to prevent users from deleting emails, yet being able to add new content via imap, what i mean is that a user should be able to create an email in its mailbox (maildir actually is used), but once the email is there the user shouldn't be able to delete it. do you know if there is a way to accomplish this for each subfolder on a Maildir environment? Thanks in advance Francesco

[Dovecot] Shared Namespace and correct location
by Dieter Knopf 05 Mar '14

05 Mar '14

Hello again, i still have problems using a Shared Namespace in my configuration. I'm using Dovecot 2.2.9. mail_location = maildir:/home/vmail/%d/%n/MAILDIR:INDEX=/home/vmail/%d/%n/INDEX/ namespace inbox { type = private separator = / prefix = inbox = yes } This works create. But: namespace { type = shared separator = / prefix = shared/%%u/ location = maildir:/home/vmail/%%d/%%u/MAILDIR/shared:INDEX=/home/vmail/%d/%u/INDEXS/%%u subscriptions = no list = children } I'm still not sure how i can see a shared mailbox on a different account. I can add ACL rules and dovecot is adding SQL-Entries to the user-shares table. The dovecot-acl-list file is created too, hope this is okay (vfile + SQL) But i can't see the shared folder on the target account. I tried many location-pathes, but not sure how i can add the right folder. There must be a problem with %%d and %%u. Thank you very much, Dieter

[Dovecot] Dovecot Migration: Retrieving/Logging POP/IMAP Passwords in Plaintext
by Traiano Welcome 05 Mar '14

05 Mar '14

Hi List I'm currently in the process of migrating my dovecot imap/pop users to a new server and have to extract their passwords in order to import them into the new system (different password encryption schemes). I've tried enabling auth_* debug parameters in my dovecot.conf in the hope that this would result in logging plaintext passwords to the dovecot log. However dovecot does not log the passwords in plaintext under any debugging configuration. My question: Is there any other configuration of dovecot that would allow me to capture POP/IMAP passwords at a successful login time? Dovecot version: 1.0.7 (from dovecot-1.0.7-7.el5_7.1 rpm) The output of dovecot -n is: --- # 1.0.7: /etc/dovecot.conf info_log_path: /var/log/dovecot.debug verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_location: mbox:~:INBOX=~/Mailbox mail_debug: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 auth default: mechanisms: plain login verbose: yes debug: yes debug_passwords: yes passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 438 --- My dovecot.conf is as follows: ------ info_log_path = /var/log/dovecot.debug verbose_ssl = yes mail_location = mbox:~:INBOX=~/Mailbox mail_debug = yes protocol imap { } protocol pop3 { } protocol lda { postmaster_address = postmaster(a)example.com } auth_verbose = yes auth_debug = yes auth_debug_passwords = yes auth default { mechanisms = plain login passdb pam { } userdb passwd { } user = root socket listen { client { path = /var/run/dovecot/auth-client mode = 0666 } } } dict { } plugin { } --- Many thanks in advance!

[Dovecot] Using AD, one more try - "successfol auth" and crashing auth process
by Jeroen Scheerder 05 Mar '14

05 Mar '14

Hi, I have no success in using AD with dovecot. The little checkpassword script I cooked up that uses ldapsearch to lookup a user DN (with an authenticated bind) and then ldapsearch with an authenticated bind for that DN again works well. * Approach 1: use a service account to bind to AD, lookup the user DN, and bind to that DN. It fails. The LDAP config looks like: hosts = dc2.office.on2it.net ldap_version = 3 base = dc=office,dc=on2it,dc=net scope=subtree auth_bind = yes dn = CN=DovecotSvc,OU=Svcs,DC=office,DC=on2it,DC=net dnpass = suppressed pass_attrs = sAMAccountName=user pass_filter = (&(objectClass=person)(sAMAccountName=%u)) user_attrs = sAMAccountName=user user_filter = (&(objectClass=person)(sAMAccountName=%u)) What happens in this case is best shown in the packet capture as displayed by tshark: $ tshark -o tcp.check_checksum:FALSE -tr -r dc2.pcap 1 0.000000 172.17.50.13 -> 172.17.10.2 LDAP 197 bindRequest(7) "CN=DovecotSvc,OU=Svcs,DC=office,DC=on2it,DC=net" simple 2 0.001879 172.17.10.2 -> 172.17.50.13 LDAP 88 bindResponse(7) success Yay! The service account binds just fine. 3 0.001967 172.17.50.13 -> 172.17.10.2 LDAP 180 searchRequest(8) "dc=office,dc=on2it,dc=net" wholeSubtree 4 0.002772 172.17.10.2 -> 172.17.50.13 LDAP 502 searchResEntry(8) "CN=Jeroen Scheerder,OU=Users,DC=office,DC=on2it,DC=net" \ | searchResRef(8) | searchResRef(8) | searchResRef(8) | searchResDone(8) success 5 0.098367 172.17.50.13 -> 172.17.10.2 TCP 66 49416 > 389 [ACK] Seq=246 Ack=459 Win=1037 Len=0 TSval=602425599 TSecr=124473537 Yay!

The user DN bind works. But wait, why is it taking dovecot 225 seconds to get around to trying it? The auth process has already given up. * Approach 2: A template defines the user DN. Bind to that DN. AD DNs don't contain usernames, but AD allows all kinds of non-LDAP shorthands for DNs, inclusing %user%@domain. I've verified this to work using ldapsearch: $ ldapsearch -o ldif-wrap=no -x -LLL -E pr=200/noprompt -H ldap://dc2.office.on2it.net \ -b dc=office,dc=on2it,dc=net -s sub \ -D js(a)office.on2it.net -W \ '(&(ObjectClass=person)(sAMAccountName=js))' DN Enter LDAP Password: dn: CN=Jeroen Scheerder,DC=office,DC=on2it,DC=net The config looks like: hosts = dc2.office.on2it.net ldap_version = 3 base = dc=office,dc=on2it,dc=net scope=subtree auth_bind = yes auth_bind_userdn = "%u(a)office.on2it.net" pass_attrs = sAMAccountName=user user_attrs = sAMAccountName=user What happens in this case is best shown by a snippet of dovecot logging: Mar 5 09:57:36 <mail.err> ponyboy dovecot: auth: Error: ldap(js,127.0.0.1,<z1dLNtjzJwB/AAAB>): ldap_search(base=dc=office,dc=on2it,dc=net filter=(&(objectClass=posixAccount)(uid=js))) failed: Operations error Mar 5 09:57:36 <mail.err> ponyboy dovecot: imap: Error: Disconnected from auth server, aborting (client-pid=7247 client-id=1) Mar 5 09:57:36 <mail.crit> ponyboy dovecot: auth: Fatal: master: service(auth): child 7245 killed with signal 11 (core not dumped - set service auth { drop_priv_before_exec=yes }) Mar 5 09:57:36 <mail.info> ponyboy dovecot: imap-login: Internal login failure (pid=7247 id=1) (internal failure, 1 successful auths): user=<js>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=7248, secured, session=<z1dLNtjzJwB/AAAB> I find this intriguing -- "1 successful auths", so says imap-login, with auth dying horribly. I smell a rat. Something's wrong here...

[Dovecot] Send and Bounced mail not appearing, depending on mail client
by Dominique 05 Mar '14

05 Mar '14

Hi, I just installed Dovecot2 on Ubuntu 12.04 server with postfix and postfixadmin. I am using virtual users and virutal domains. When using Thunderbird, Roundcubemail,iOS mail application on an iPad2 or Kmail n Android, all mail sent and bounce shows up. However, when using vTigerCRM to send mails, nothing shows up - anywhere. I know the mail are being send - as per the mail.log and the various postfix log lines. But none of that is being captured by Dovecot... What am I missing? Thanks for any hints you can provide.

This does not test what you want, which is trying to authenticate the master user, not the regular user. From what I remember of your config, you have another passdb which holds the credentials of your master user: you need to check that file to make sure the master user's password (hash) matches what you think the master password ought to be.

[Dovecot] Hidden virtual folder
by Moritz Augsburger 04 Mar '14

04 Mar '14

Hi, I wanted to create a virtual folder containing all unread messages and the threads they belong to, and this config works really fine: > dovecot.conf: namespace { type = private prefix = virtual/ separator = / location = virtual:~/Maildir/virtual:INDEX=MEMORY list = children subscriptions = no } > virtual/All/dovecot-virtual: * -Trash -Trash/* -Junk -Junk/* -Drafts -Drafts/* -virtual -virtual/* all > virtual/New/dovecot-virtual: virtual/All inthread refs or unseen recent The only problem I got is that scanning all files for the virtual/All mailbox takes too long, and I would like to keep them cached (no INDEX=MEMORY), so I thought I'll just put virtual/All inside a second virtual namespace. As it's a bad idea to open the All directory manually, I could also hide the complete namespace to the user. So I added the following to my config: namespace { type = private prefix = virtual-all/ separator = / location = virtual:~/Maildir/virtual-all/ hidden = yes list = no subscriptions = no } But sadly it didn't work, a directory virtual-all/ pops up inside my client (thunderbird/icedove). Is hidden=yes/list=no unsupported for virtual locations, or is it me misconfiguring dovecot? If it should matter, it's version 2.2.9, or more specific debian 1:2.2.9-1~bpo70+1. Thanks Moritz

Hi, I did the upgrade frpom 1.2.x to 2.2.10 and had some warnings/errors on a very few accounts/mailboxes. All of them where permission related and solved. Dovecot rocks again. But on one mailbox I do get an error: Error: user rechnnugseingang-animationsinstitut: Initialization failed: Initializing mail storage from mail_location setting failed Error: Invalid user settings. Refer to server log for more information. There is a homedirectory and the permissions are set like on all other accounts.

[Dovecot] Dovecot, AD and authenticated binds...
by Jeroen Scheerder 03 Mar '14

03 Mar '14

I posted earlier with reports of less than stellar success in using Active Directory for dovecot authentication. My approach is to using the two-step approach of - obtaining the user DN by a search using an authenticated bind (using a service account) - then binding as that DN, and returning the relevant user attributes This hasn't been succesful. Dovecot's authentication process does perform the (first) authenticated bind successfully, it does obtain the right DN, than just sits there doing nothing as far as I can tell, and after a long delay concludes authentication failure - shortly before deciding to perform the bind with the user-supplied credentials, successfully. Source inspection has not resulted in a glorious eureka yet. So I thought, why not handle it myself? And I wrote a little script, using the checkpassword interface. I've enclosed it. The script is based on <http://wiki2.dovecot.org/AuthDatabase/CheckPassword>, but somehow the userdb_uid and userdb_gid I've passed back in the "EXTRA" environment variable get lost along the way. It syslogs, and the syslogs show that the LDAP parts working as expected: Mar 3 14:49:09 <mail.info> ponyboy checkpassword: successful authenticated bind and DN(js) lookup Mar 3 14:49:09 <mail.info> ponyboy checkpassword: DN(js) is CN=Jeroen Scheerder,OU=Users,OU=Netherlands,OU=ON2IT,DC=office,DC=on2it,DC=net Mar 3 14:49:09 <mail.info> ponyboy checkpassword: js authenticated In dovecot's log, simultaneously, I see basically a successful login, except that the (user_)uid and (userdb_)gid work - unless I disable prefetch, and use a static userdb: Mar 03 14:49:04 auth: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth Mar 03 14:49:04 auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat Mar 03 14:49:04 auth: Debug: auth client connected (pid=90856) Mar 03 14:49:09 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=+qFODbTzDgB/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=143 rport=63246 resp=<hidden> Mar 03 14:49:09 auth: Debug: checkpassword(js,127.0.0.1,<+qFODbTzDgB/AAAB>): execute: /usr/local/etc/dovecot/checkpassword-on2it /usr/local/libexec/dovecot/checkpassword-reply Mar 03 14:49:09 auth: Debug: checkpassword(js,127.0.0.1,<+qFODbTzDgB/AAAB>): Received input: userdb_uid=143 userdb_gid=143 Mar 03 14:49:09 auth: Debug: checkpassword(js,127.0.0.1,<+qFODbTzDgB/AAAB>): exit_status=0 Mar 03 14:49:09 auth: Debug: client passdb out: OK 1 user=js Mar 03 14:49:09 auth: Debug: master in: REQUEST 4007395329 90856 1 29571963894e557ab643d2e51872ba55 session_pid=90899 request_auth_token Mar 03 14:49:09 auth: Debug: prefetch(js,127.0.0.1,<+qFODbTzDgB/AAAB>): success Mar 03 14:49:09 auth: Debug: master userdb out: USER 4007395329 js uid=143 gid=143 auth_token=e2d7c2463dd4c039010e904afb4ea45214cb7de5 Mar 03 14:49:09 imap-login: Info: Login: user=<js>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=90899, secured, session=<+qFODbTzDgB/AAAB> Mar 03 14:49:09 imap: Error: user js: Mail access for users with UID 143 not permitted (see first_valid_uid in config file, uid from userdb lookup).

[Dovecot] Tracking logins
by Alex 03 Mar '14

03 Mar '14

Hi, I'm using dovecot-2.1.17 on fc18 and wondered if there is some mechanism, perhaps a database, that can store the logins/logouts for each user? I realize there's something already logged to syslog, but I'd like more of a history. While lastlog is great for users that actually login, my dovecot users don't login, just check email via pop and imap. Any ideas greatly appreciated. Thanks, Alex

[Dovecot] maildir quota divergence
by Juan Carlos Sanchez 03 Mar '14

03 Mar '14

Hello; We are using maildir quotas and have found differences in many users in respect to what system command are showing and doveadm quotas. For example, four user test, we have: doveadm quota get -u test Quota name Type Value Limit % STORAGE 98066 102400 95 MESSAGE 883 - 0 But if we check user mail_location with "du" system command we get he is using 70458 Kb. We are running dovecot 2.1.17 ¿any clue? Thanks in advance.

[Dovecot] No speed improvement with FTS for iOS 7?
by Nicholas Riley 02 Mar '14

02 Mar '14

Hi, I recompiled Dovecot with Lucene FTS to try to improve iOS 7 IMAP search speed. Unfortunately this does not seem to help. I have 60 mailboxes, totaling 300 MB; lucene-indexes is 30 MB in size. % doveadm mailbox status -t all '*' messages=16335 recent=0 unseen=1736 vsize=280049586 Searching for a single word which is present in two messages of one mailbox takes 40 seconds to return. This is true whether or not fts is enabled. doveadm search takes much less than 1 second to do the same search. % time doveadm search BODY cython d8f09230c97af952b60c0000c1443b93 1 d8f09230c97af952b60c0000c1443b93 2 doveadm search BODY cython 0.18s user 0.05s system 99% cpu 0.230 total With fts disabled, it takes about 6.5 seconds. This is still a long way from 40 seconds. Is there any way I can make dovecot perform better here? Thanks, -- Nicholas Riley <njriley(a)illinois.edu>

[Dovecot] + prefix in dovecot-virtual
by Nicholas Riley 01 Mar '14

01 Mar '14

Hi, The "+" prefix in dovecot-virtual does not seem to be documented. only discovered it because I tried to include a mailbox whose name began with + and Dovecot gave me an error when I tried to copy to it. I see it was added here: http://hg.dovecot.org/dovecot-2.2/rev/be0f0de75e34 My dovecot-virtual file looked like this: !+/2014-03 +/2014-02 all I just added another + to the second line and it seems to work. I don't care about \Recent thankfully but is there a better way to specify a mailbox whose name begins with +? Thanks. -- Nicholas Riley <njriley(a)illinois.edu>

[Dovecot] Force SSL authentication per user basis
by Urban Loesch 28 Feb '14

28 Feb '14

Hi, I'm searching a way to force encrypted connections for POP3/IMAP on a per user basis. To not break clients which still connect in plaintext (there are still many of it) I must implement a mechanism to force encrypted connections on a per user basis. The users and passwords are stored in a mysql database. So there would be no problem to expand the database with a column like "ssl_tls" -> yes/no. The problem now: how can I get dovecot to process this field in the right way? I searched the list and googled about such a way, but I can't find any solution. My Dovecot version is 2.2.12. Many thanks and regards Urban Loesch

[Dovecot] Logging authentication failures when Dovecot's auth service used to authenticate postfix smtpd
by MV 28 Feb '14

28 Feb '14

Hello, tl;dr: Is there a way to get dovecot's auth to log failed smtp authentications without having to switch on "auth_verbose"? postfix version 2.11.0 and dovecot version 2.2.12 I'm currently migrating my postfix+courier to postfix+dovecot and so far it's working as expected. Except for logging smtp login failures. Despite Postfix logging successful authentications (see sample below), it doesn't log failed smtp logins. Feb 25 22:28:53 mailer2 postfix/submission[20274]: C981B20198: client=A-B-C-D.*****.net[A.B.C.D]:63107, sasl_method=PLAIN, sasl_username=joe(a)example.net And since my postfix setup authenticates virtual users through Dovecot's auth, I thought maybe dovecot could report smtp login failures the same way it reports imap and pop3 login failures. Below is a sample extracted from "info_log_path" after several imap and pop3 login failures. (Obviously the IP 255.... is made up and irrelevant for this mater). # begin extract "/var/log/dovecot-info.log" 2014-02-27 21:14:26 auth: Info: passwd-file(joe(a)example.net,255.255.255.255,<Y0lbzmnzfwAuQV80>): Password mismatch 2014-02-27 21:16:46 auth: Info: passwd-file(foobar,255.255.255.255,<Y0lbzmnzfwAuQV80>): unknown user 2014-02-27 21:52:00 auth: Info: passwd-file(foo(a)example.net,255.255.255.255,<0Su6VGrzGwAuQV80>): unknown user 2014-02-27 21:53:35 auth: Info: plain(?,255.255.255.255,<0Su6VGrzGwAuQV80>): Empty username 2014-02-27 21:53:55 auth: Info: plain(?,255.255.255.255,<0Su6VGrzGwAuQV80>): Username character disallowed by auth_username_chars: 0x5c (username: \0) 2014-02-27 22:08:05 auth: Info: plain(?,255.255.255.255): invalid input 2014-02-27 22:09:36 auth: Info: passwd-file(joe(a)example.net,255.255.255.255): Password mismatch 2014-02-27 22:09:53 auth: Info: login(?,255.255.255.255): Empty username # end extract I've tried adding "-L -o info_log_path=/var/log/dovecot-info.log" to the both auth and auth-worker services but that yield nothing. ----------------------%<-------------------------------- auth_mechanisms = plain login auth_verbose = yes base_dir = /var/run/dovecot/ info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " passdb { args = scheme=CRYPT username_format=%u /etc/dovecot/virtual_users driver = passwd-file } userdb { args = username_format=%u /etc/dovecot/virtual_users default_fields = uid=vmail gid=vmail driver = passwd-file override_fields = home=/home/vmail/%d/%u result_failure = return-fail result_internalfail = return-fail } service auth-worker { executable = auth -w -L -o info_log_path=/var/log/dovecot-info.log } service auth { executable = auth -L -o info_log_path=/var/log/dovecot-info.log unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix user = postfix mode = 0660 } } service lmtp { executable = lmtp -L -o info_log_path=/var/log/dovecot-info.log unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix user = postfix mode = 0660 } } ---------------------->%-------------------------------- The relevant postfix config is ... smtpd_sasl_type = dovecot smtpd_sasl_path = private/dovecot-auth virtual_transport = lmtp:unix:private/dovecot-lmtp

[Dovecot] Dovecot2 vs. AD, "Inactivity during authentication"
by Jeroen Scheerder 28 Feb '14

28 Feb '14

Hi, I'm trying to setup Dovecot2 for o IMAP client access o LDA for postfix mail delivery (with SIEVE) ... on a FreeBSD host. The FreeBSD server has no users (by intention), so I've set up a virtual mail domain, using LDAP lookups in Postfix. So far so good. Mail delivers into the proper mailbox. But I'm stuck getting Dovecot to authenticate. User- and passwd DB's are set up for LDAP lookups to AD, using an authenticated bind (the AD server offers no anonymous binds, yet). I've enabled all the debugging I can find, but my logs have little information to offer. Any help in getting me a step further would be much appreciated. In particular, I'd like to learn how do diagnose these userdb/passdb issues properly. Here's what I see in the logs: Feb 27 12:25:49 <mail.info> ponyboy dovecot: imap-login: Disconnected: Inactivity during authentication (disconnected while authenticating, waited 172 secs): user=<>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured, session=<r/ERi2HzQAB/AAAB> Feb 27 12:26:42 <mail.err> ponyboy dovecot: auth: Error: PLAIN(js,127.0.0.1,<r/ERi2HzQAB/AAAB>): Request 74099.1 timed out after 225 secs, state=1 This logging is related to the folloging IMAP session: ponyboy% telnet localhost 143 Trying 127.0.0.1...

Following this guide: http://sys4.de/en/blog/2013/04/08/postfix-dovecot-mailbox-quota/ I can't seem to get it to work, as soon as I add the smtpd_recipient_restrictions setting to postfix I can no longer send mail at all. I get the message SMTP Error (450): Failed to add recipient "postmaster(a)example.com" (4.7.1 : Recipient address rejected: Internal error occurred. Refer to server log for more information.). I googled around and found this command to test the quota-status service: printf "recipient=postmaster at example.com\nsize=1234\n\n" | nc 127.0.0.1 12340 It seems to always return the quota_status_nouser message. I'm really stumped here. What logs do I need to check for errors and does anyone have any experience with this? I'm running Dovect 2.2.10 with Postfix 2.6.6 Here's my dovecot -n result: # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.5.1.el6.x86_64 x86_64 CentOS release 6.5 (Final) auth_master_user_separator = * auth_mechanisms = PLAIN LOGIN dict { acl = mysql:/etc/dovecot/dovecot-share-folder.conf quotadict = mysql:/etc/dovecot/dovecot-used-quota.conf } first_valid_uid = 2000 last_valid_uid = 2000 listen = * log_path = /var/log/dovecot.log mail_gid = 2000 mail_location = maildir:/%Lh/Maildir/:INDEX=/%Lh/Maildir/ mail_plugins = quota mail_uid = 2000 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 namespace { inbox = yes location = prefix = separator = / type = private } namespace { list = children location = maildir:/%%Lh/Maildir/:INDEX=/%%Lh/Maildir/Shared/%%u prefix = Shared/%%u/ separator = / subscriptions = yes type = shared } passdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } passdb { args = /etc/dovecot/dovecot-master-users-password driver = passwd-file master = yes } plugin { acl = vfile acl_shared_dict = proxy::acl auth_socket_path = /var/run/dovecot/auth-master autocreate = INBOX autocreate2 = Sent autocreate3 = Trash autocreate4 = Drafts autocreate5 = Junk autosubscribe = INBOX autosubscribe2 = Sent autosubscribe3 = Trash autosubscribe4 = Drafts autosubscribe5 = Junk quota = dict:user::proxy::quotadict quota_grace = 10%% quota_rule = *:storage=1G quota_status_nouser = DUNNO quota_status_overquota = 552 5.2.2 Mailbox is full quota_status_success = DUNNO quota_warning = storage=85%% quota-warning 85 %u quota_warning2 = storage=90%% quota-warning 90 %u quota_warning3 = storage=95%% quota-warning 95 %u sieve = /%Lh/sieve/dovecot.sieve sieve_dir = /%Lh/sieve sieve_global_dir = /var/vmail/sieve sieve_global_path = /var/vmail/sieve/dovecot.sieve } protocols = pop3 imap sieve service auth { unix_listener /var/spool/postfix/dovecot-auth { group = postfix mode = 0666 user = postfix } unix_listener auth-master { group = vmail mode = 0666 user = vmail } unix_listener auth-userdb { group = vmail mode = 0660 user = vmail } } service dict { unix_listener dict { group = vmail mode = 0660 user = vmail } } service imap-login { process_limit = 500 service_count = 1 } service pop3-login { service_count = 1 } service quota-status { client_limit = 1 executable = quota-status -p postfix inet_listener { port = 12340 } } service quota-warning { executable = script /usr/local/bin/dovecot-quota-warning.sh unix_listener quota-warning { group = vmail mode = 0660 user = vmail } } ssl = required ssl_cert = </etc/pki/tls/certs/iRedMail_CA.pem ssl_key = </etc/pki/tls/private/iRedMail.key userdb { args = /etc/dovecot/dovecot-mysql.conf driver = sql } protocol lda { auth_socket_path = /var/run/dovecot/auth-master lda_mailbox_autocreate = yes log_path = /var/log/sieve.log mail_plugins = quota sieve autocreate postmaster_address = root } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep mail_plugins = quota imap_quota autocreate } protocol pop3 { mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } For my postfix/main.cf I have this relevant setting: smtpd_recipient_restrictions = reject_unknown_sender_domain, reject_unknown_recipient_domain, reject_non_fqdn_sender, reject_non_fqdn_recipient, reject_unlisted_recipient, check_policy_service inet:127.0.0.1:7777, check_policy_service inet:127.0.0.1:10031, check_policy_service inet:127.0.0.1:12340, permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination

[Dovecot] dsync mirror to mailstores in director setup

27 Feb '14

Hi All, I have dsync mirror command working between a standalone dovecot server and a backend mailstore in a Dovecot Director setup. Is it safe to do the dsync directly to the backend mailstore in this setup? It doesn't seem to work via the director proxy. Thanks Murray

[Dovecot] 2 users database on same LDAP with different mail location
by Francesco 26 Feb '14

26 Feb '14

Hello, i know i know, i'm getting annoying but appearently i always come up with weird ideas and i cant seem to accomplish such a task. the scenario is that i have an LDAP server with a bunch of users. some of them are in a specific OU, and i'd like to define for all these users belonging to this OU an alternative mail location/storage. in details for all the users i'd like to use maildir storage in a directory, while for the users belonging to a specific OU i'd like to use dbox with an alternative storage attached. so i created 2 userdb like this: userdb { driver = ldap args = /etc/dovecot/dovecot-ldap-maildir.conf.ext } userdb { driver = ldap args = /etc/dovecot/dovecot-ldap-dbox.conf.ext } and then defined these 2 args files: maildir: hosts = localhost dn = CN=ldapadmin,OU=administrators,DC=plutone,DC=local dnpass = <password> auth_bind = yes ldap_version = 3 base = DC=plutone,DC=local user_attrs = sAMAccountName=home=/var/vmail/%$ dbox: hosts = localhost dn = CN=ldapadmin,OU=administrators,DC=plutone,DC=local dnpass = <password> auth_bind = yes ldap_version = 3 base = OU=dboxusers,OU=lowpriority,DC=plutone,DC=local user_attrs = sAMAccountName=home=/var/local_dbox/%$, =mail=dbox:/var/local_dbox/%$:ALT=/var/iscsi_dbox/%$ user_filter = (&(ObjectClass=person)(mail=%u)) yet it doesn't matter how hard i try if i send an email to a user belonging to the dboxusers OU i still have the user to be addressed to the maildir storage in /var/vmail am i missing something? Thanks Francesco

[Dovecot] Dovecot upgrade 1 to 2 on Debian Squeeze : broken /var/run/dovecot

Hi, I just upgraded from version 1 to version on Debian Squeeze using their backports. Like I expected my dovecot1 config had to be converted using doveconf and this I did. However, I see problems with files inside directory: drwxr-xr-x 4 dovenull root 4096 Feb 25 20:35 /var/run/dovecot All of them were created owned by root:root rw. I tried to changed, for example : chown postfix:dovecot /var/run/dovecot/auth-master but noticed when I restarted dovecot it reset the permissions back to root:root rw.

[Dovecot] Upgrading from 1.2.x -> 2.2.x in one step possible
by Götz Reinicke - IT Koordinator 26 Feb '14

26 Feb '14

Hi, after some off-ML discussions to and some reconsiderations, we might do the "big jump" from our current 1.2.17 to the atrpms 2.2. From googling and reading the dovecot upgrade wiki I don't see any (big) pitfalls. Basically we use the default config options, mbox, pop3s/imaps on RH EL 5. So "just" run the upgrade-config script, fingers crossed and thats it? Ii it possible to do such a big step form 1.2 to 2.2? Thanks for comments and suggestions .

[Dovecot] Removing Mount Points
by Jeff Geiger 26 Feb '14

26 Feb '14

Dovecot version 2.1.7 If a dovecot mount point (drive) dies, and the data is restored into the same path that's no longer a mount point (subfolder), dovecot complains about a missing mount point. Is it safe to do a `doveadm mount remove {path}` to fix the error since it's no longer a legit mount point? Example: We were storing indexes on an SSD drive mounted at /mnt/ssd. That drive died. I was able to put everything back into the /mnt/ssd folder (no longer mounted, just a folder). Everything seems to be working as expected. But, when I just went to dsync an account from another server to this one, I got the following error: dsync(sales(a)foo.com): Error: Couldn't create index dir /mnt/ssd/indexes/6/a/ sales(a)foo.com/mailboxes: Can't create mailbox root dir /mnt/ssd/indexes/6/a/ sales(a)foo.com/mailboxes: Mountpoint /mnt/ssd isn't mounted. Mount it or remove it with doveadm mount remove Would doing a `doveadm mount remove /mnt/ssd` fix my issue, or cause some type of catastrophe? Thanks, Jeff Geiger jeff.geiger(a)firespring.com

Re: [Dovecot] AUTH_USER variable has invalid value in checkpassword Script

26 Feb '14

answering my own questions: > This has somehow changed and now AUTH_USER always > contains the username. This has fatal consequences as no > every owner of a valid certificate can logon as any user. I now use auth_ssl_username_from_cert = yes and this temporarily fixes my problem. Now if user A authenticates with his certificate and claims to be user B he will be logged on as user A. With ssl_username_from_cert = no (default) he was logged in as User B. > I'm absolutely sure that the value of the x500UniqueIdentifier > was stored into the AUTH_USER when I tested my setup > last year. If one looks at the source code, in particular routine env_put_auth_vars() in src/auth/db-checkpassword.c and routine auth_request_get_var_expand_table() in src/auth/auth-request.c it is clear, that this has never worked. The environemnt variable AUTH_USER always contais the username (in all Dovecot versions). It dows NOT contain the Dovecot auth_user-variable. Comparing AUTH_USER with the username makes no sense in a checkpassword-script So here's my next question: How do I find out the original username from within a chackpassword script after it has been replaced by the x500UniqueIdentifier value from a client certificate? Why is request->requested_login_user == NULL in env_put_auth_vars(). request->user contains the x500UniqueIdentifier value from the clients certificate so the original username was replaced and therefore should have been moved into request->requested_login_user. Kind regards Peter Koch

Hi, we still run dovecot 1.2.17 and upgrading is not planed for some time. But I'm asked to install a sieve system to be used with SOGo soon. What do I have to install / configure? Is installing/configuring the dovecot-sieve-0.1.19 and dovecot-managesieve-0.11.13 enough? We still use mostly the default settings for imaps/pop3s. And of course configure SOGo.

[Dovecot] AUTH_USER variable has invalid value in checkpassword Script
by dovecot.pkoch＠dfgh.net 25 Feb '14

25 Feb '14

Dear dovecot experts: We are using client certificates to authenthicate against a Dovecot server. Our certificates contain a x500UniqueIdentifier. I'm absolutely sure that the value of the x500UniqueIdentifier was stored into the AUTH_USER when I tested my setup last year. This has somehow changed and now AUTH_USER always contains the username. This has fatal consequences as now every owner of a valid certificate can logon as any user. Here are some more details of our setup: We are using a checkpassword-Script that does the following: 1. Read Username and Password from file descriptor 3 2. If (AUTH_CERT=="valid") and (AUTH_USER==Username) then user is authenticated 3 If (AUTH_CERT=="valid") and (AUTH_USER<>Username) then authentication is rejected (User a tries to logon as User B) 4 If (AUTH_CERT<>"valid) we calculate the current OATH value for Usernames TOTP-token and compare that with the provided password. The last step is the reason why we are using a checkpassword script. Our smartphone users cannot use a smartcard but enter a password that was created by an OTP generator, so programming my own checkpassword script was my only option. AUTH_USER contains the username even if the x500UniqueIdentifier from the users certificate does not, so step 2 happens when step 3 should happen. I did the initial testing with Dovecot 2.2.6. At that time we were using both port 143 and 993. We now use Dovecot 2.2.7 and port 993 only. This should not make a difference but I will recompile 2.2.6 right after sending this posting. Kind regards and thank you very much for this wonderful IMAP server Peter Koch current dovecot.conf: --------------------------------------------------------- # Dovecot configuration file default_process_limit = 2048 protocols = imap listen = * base_dir = /var/dovecot/ mail_location = maildir:/mail/%u:LAYOUT=fs ssl_cert = </etc/ssl/certs/imap.crt ssl_key = </etc/ssl/private/imap.key ssl_ca = </etc/ssl/certs/imap-ca.crt ssl_verify_client_cert = yes ssl_cert_username_field = x500UniqueIdentifier service imap-login { inet_listener imap { port = 0 } } service auth { client_limit = 4096 } service anvil { client_limit = 5000 } passdb { driver = checkpassword args = /usr/dovecot/bin/checkpassword } userdb { driver = passwd override_fields = home=/mail/%u } protocol imap { mail_max_userip_connections = 1000 }

[Dovecot] A question regarding doveadm replicator status
by XarHs 25 Feb '14

25 Feb '14

Hello, I am using Dovecot version 2.2.10. I am quite familiar with ssh replication and I managed to set it up correctly. The only problem I see is that when i run the command: doveadm replicator status I get a wrong "Total number of known users" which is a) is different between the two (2) replicated dovecot servers, i.e. in mail1 I get a total of 21 users and in mail2 I get a total of 20 users (it should be the same, correct?) b) is not matching the total number of users I have in each server (mail1, mail2) which I am also getting when counting the total users with "doveadm" service enabled. (the command doveadm user '*' | wc lists a total of 16 users for both mail1, mail2 servers, which is also the total number of users that exist indeed in the LDAP structure with the doveadm service enabled. Is there any way to reset the value of "Total number of known users"? Do I have to delete a file in /var/run/dovecot or something in order to do it? The only way I tried (not successfully though) to reset it is by executing the command: for i in `doveadm user '*'` ;do doveadm replicator remove $i ; done which does empties all existing users (16), but leaves me with Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 0 Waiting 'failed' requests 0 Total number of known users 5 in mail1 server and Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 0 Waiting 'failed' requests 0 Total number of known users 4 in mail2 server, i.e. the value is 5 (21-16) for mail1 and 4 (20-16) for mail2 server. After seeing that I tried to restart dovecot service, which again ended in the following numbers: Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 0 Waiting 'failed' requests 0 Total number of known users 21 in mail1 server and Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 0 Waiting 'failed' requests 0 Total number of known users 20 in mail2 server thus their values augmented back to +16, meaning dovecot read succesfully my 16 users. I have not found a way to successfully reset the "Total number of known users" numbers back to the valid 16 users, which is also returned by running the command: doveadm user '*' | wc Why do I have those differences? How is the "Total number of known users" being calculated? What should I do to effectively reset to to the normal value (which in my case is 16)? Thanks in advance.

[Dovecot] tests with metadata module
by Mihai Badici 25 Feb '14

25 Feb '14

--Repost after subscription as list member --- I made some tests with metadata support in dovecot 2.2.10. Previously I had dovecot 2.2.4 with external metadata plugin who work well. I use dovecot with roundcube and roundcube plugins from kolab project . First, the feature activation was tricky and rather undocumented. I spent about half hour googling, after that I set: imap_metadata = yes and mail_attribute_dict = file:%h/shared_metadata I think you cold put those lines in the 20-imap.conf example file commented; that way will be easy for us to activate. Because I changed the location of shared_metadata, all folders was unannotated . I went in folder manager in roundcube and set folder "calendar" as calendar type and so on.

[Dovecot] Detail improvement: %c variable
by Hadmut Danisch 25 Feb '14

25 Feb '14

Hi, although dovecot is great and almost exactly solving my problems and fitting my requirements, there is an odd detail that causes me problems: The %c variable. (See http://wiki2.dovecot.org/Variables ) I'm managing an IMAP server for an association, which is connected to an LDAP server. Users can connect in three ways: IMAPS from the internet, IMAP from local acccounts, and IMAP through a Web->IMAP interface, which is protected through additional one-time-passwords. The web gateway is intended to be used from untrusted computers as well, so the IMAP password entered through the Web site must not be the same as the password used on IMAPS. I have solved this problem by using %s%c as part of the LDAP user_filter. When people connect over IMAPS, this becomes imapsecured (%s=imap, %c=secured), while an unencrypted connect becomes imap (%s=imap, %c=) Unfortunately, this works only, if the web interface and the IMAP server are located on different (virtual) machines. But if the web gateway and dovecot are no the /same/ machine, this does not work anymore, since %c becomes "secured" on localhost, even if unencrypted. It causes a lot of trouble and headache. Please add a configuration variable to configure, whether %c should become "secured" for unencrypted traffic on the loopback device (localhost). regards Hadmut

[Dovecot] realtime backup with LDA?
by Francesco 25 Feb '14

25 Feb '14

Hello everyone, i was reading the dovecot-lda documentation as i'm using LDA as a delivery agent on my current mailserver configuration. I was curious to know if there are some options for having a message to be delivered to a "twin mailbox" upon delivery. this twin mailbox would work as a backup archive for recovering emails in case the user accidentally deletes them. so if i have a user which is alice i would create a second mailbox named backup_alice or whatever respecting a predictable schema and then every mail delivered to alice would also be delivered to backup_alice. do you know if this can be done? have any example? i was also planning to use shared folders + ACLS to have backup_alice accessible as a read only mailbox directly from the alice imap account. thanks in advance Francesco

[Dovecot] Why are ACLs for non-existent mailboxes accepted?
by Boris 25 Feb '14

25 Feb '14

Dovecot 2.2.9-1 accepts SETACL commands that share mailboxes to non-existent mailboxes. There is no error message. Is this intended behavior? I think it's bad because clients present a success message when indeed the intent of the user failed. Typos are hard to catch.

[Dovecot] dsync, a zero-way synchronisation tool?
by Fabiano Sidler 24 Feb '14

24 Feb '14

Hi folks! I have set up dsync replication with SSH according to http://wiki2.dovecot.org/Replication with the exception of having system users and calling doveadm dsync-server directly from authorized_keys, because the wrapper script posted on the above site is needless (at least in 2.2.10). However, while the two instances connect well to each other, no synchronisation is performed at all, the mailboxes happily remain untouched. I've then temporarily replaced SSH with socat and captured the traffic. Any hints what goes wrong? Unfortunately there are no logs to provide... Greetings, Fabiano

[Dovecot] doveadm mailbox command in multi instance setup
by Peer Heinlein 22 Feb '14

22 Feb '14

We're running Dovecot in a multipe instance cluster with individual userdb-querys to different LDAP-Servers. As far as I can see there's no way to use the doveadm mailbox command with different Auth-Sockets or different configurations. While root@dobby4:/etc/dovecot# doveadm user -a /var/run/dovecot-xy/auth-master p.heinlein(a)example.com field value uid 10000 gid 10000 home /mail/example.com/123456/ mail mdbox:~/mdbox quota_rule2 *:storage=50G is working, using doveadm -c /etc/dovecot/dovecot-xy.conf mailbox list -u p.heinlein(a)example.com does NOT an (user unknown). How can use a different auth socket with "doveadm mailbox" commands? (Maybe using the network socket could be a working way, but what about normal way on the command line?)

Dovecot Version: 2.2.12 Postfix Version: 2.9.6 Hello I've configured the quota-status service (socket and port).

How it's possible to debug the quota-status for understand why to postfix the service return DUNNO and not 552 ?

It seems that dovecot is using the current time, not a maildir file's mtime for INTERNALDATE when a message is re-indexed: $ cd Index $ rm -rf .INBOX $ cd ../Maildir/cur $ stat * File: `1392914632.P54451Q0M08633.smtpin01,S=2215,W=2249:2,' Size: 960 Blocks: 8 IO Block: 1048576 regular file Device: 36h/54d Inode: 11132959 Links: 1 Access: (0600/-rw-------) Uid: ( 8/ mail) Gid: ( 8/ mail) Access: 2012-01-01 00:00:00.000000000 +0000 Modify: 2012-01-01 00:00:00.000000000 +0000 Change: 2014-02-20 16:46:20.000000000 +0000 Birth: - $ telnet imap01 143 Trying 10.5.45.1...

Connection closed by foreign host. $ date Thu Feb 20 16:59:58 UTC 2014 Stracing the imap process, it seems dovecot does not stat the message file at all. Performing the above with an old dovecot 1 server yields the expected result, the INTERNALDATE of the message is the file's mtime. $ dovecot -n -c /he/dovecot/conf/dovecot.conf # 2.2.10.3: /he/dovecot/conf/dovecot.conf # OS: Linux 3.4.46-dom0-2.0.0 x86_64 Debian 7.0 debug_log_path = syslog disable_plaintext_auth = no first_valid_uid = 8 info_log_path = syslog lock_method = dotlock log_timestamp = mail_fsync = always mail_gid = mail mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = zlib quota tc_mail_log notify tc_proc mail_temp_dir = /var/run/dovecot_tmp mail_uid = mail maildir_very_dirty_syncs = 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 mmap_disable = yes namespace inbox { inbox = yes location = prefix = } passdb { args = host=localhost port=1143 username=%L{user}::%L{service}::%L{rip}::%L{session} driver = imap } plugin { antispam_backend = pipe antispam_debug_target = syslog antispam_pipe_program = /he/dovecot/utils/he_spamtrain.pl antispam_pipe_program_args = --user=%u antispam_pipe_program_notspam_arg = --falsepositive antispam_pipe_program_spam_arg = --missed antispam_pipe_tmpdir = /var/run/dovecot_as_tmp antispam_signature_missing = move antispam_spam = Spam;Inbox.Spam;INBOX.Spam;Junk;INBOX.Junk antispam_trash_pattern_ignorecase = trash mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename flag_change append mail_log_fields = uid box msgid flags hetag memcached_servers = 10.5.47.223,10.5.47.222 zlib_save = gz zlib_save_level = 6 } protocols = imap pop3 service anvil { unix_listener anvil-auth-penalty { mode = 00 } } service imap-login { inet_listener imap { address = 0 } inet_listener imaps { port = 0 } process_limit = 29 process_min_avail = 14 service_count = 0 } service imap-postlogin { executable = script-login -d /he/dovecot/utils/post_login.sh } service imap { executable = imap imap-postlogin process_limit = 1270 vsz_limit = 0 } service pop3-login { inet_listener pop3 { address = 0 } inet_listener pop3s { port = 0 } process_limit = 29 process_min_avail = 14 service_count = 0 } service pop3-postlogin { executable = script-login -d /he/dovecot/utils/post_login.sh } service pop3 { executable = pop3 pop3-postlogin process_limit = 206 vsz_limit = 512 M } ssl = no userdb { args = /he/dovecot/conf/dovecot-tc-dict-auth.conf driver = dict } verbose_proctitle = yes protocol imap { mail_max_userip_connections = 30 mail_plugins = zlib quota tc_mail_log notify tc_proc imap_quota antispam } protocol pop3 { mail_max_userip_connections = 30 pop3_uidl_format = %08Xv%08Xu }
