[Dovecot] coredump in dovecot 2.0.11
by k b 09 Apr '11

09 Apr '11

Hi. I use dovecot-2.0.11-1.fc14.i686 on linux,redhat fedora 14. Using alpine 2.02 and Kmail 1.13.5 i have one IMAP connection to the dovecot server and one IMAP connection to a MS exchange server. After i moved a few messages from the exchange server i cannot open the folders where i placed the moved mails. instead dovecot crashes, all other directories and emails work fine. here is what i see in /var/log/messages: Apr 9 08:23:10 server00 abrt[28509]: saved core dump of pid 28508 (/usr/libexec/dovecot/imap) to /var/spool/abrt/ccpp-1302330190-28508.new/coredump (626688 bytes) Apr 9 08:23:10 server00 abrtd: Directory 'ccpp-1302330190-28508' creation detected Apr 9 08:23:10 server00 abrtd: Crash is in database already (dup of /var/spool/abrt/ccpp-1302111878-7921) Apr 9 08:23:10 server00 abrtd: Deleting crash ccpp-1302330190-28508 (dup of ccpp-1302111878-7921), sending dbus signal I can post the coredump but i will have to clean it first as i can see it contains a few emails. would it help to post the coredump or shuould i skip that?

[Dovecot] mysql lookup on another host performance q?

Hi, new to dovecot I'm setting a small postfix/dovecot server for virtual domain/users in mysql dovecot is on one host, mysql on another seems to be working, but I'm concerned over performance overhead of this setup; dumb Q, is there any 'proxy mysql' or cacheing option I can use ? any suggestions appreciated also, my mail users as set as 5000/5000 virtual_gid_maps = static:5000 virtual_uid_maps = static:5000 so, I should use uid/gid 5000/5000 in query below, yes ? thanks -- Voytek --------------------------------------------------------- # dovecot --version 1.2.9 Linux 2.6.32-21-generic-pae #32-Ubuntu SMP Fri Apr 16 09:39:35 UTC 2010 i686 GNU/Linux # grep -v '^ *$#.*$\?$' dovecot-sql.conf driver = mysql connect = host=host.tld dbname=ddd user=ccc password=xxx user_query = SELECT concat('/var/mail/vhosts/', maildir) as home, concat('maildir:/var/mail/vhosts/', maildir) as mail, 5000 AS uid, 5000 AS gid, concat('maildir:storage=', quota) AS quota FROM mailbox WHERE username = '%u' AND active = '1' default_pass_scheme = MD5 user_query = SELECT '/var/mail/vhosts/%d/%n@%d' as home, 'maildir:/var/mail/vhosts/%d/%n@%d' as mail, 5000 AS uid, 5000 AS gid, concat('dirsize:storage=', quota) AS quota FROM mailbox WHERE username = '%u' AND active = '1' password_query = SELECT username as user, password, '/var/mail/vhosts/%d/%n@%d' as userdb_home, 'maildir:/var/mail/vhosts/%d/%n@%d' as userdb_mail, 5000 as userdb_uid, 5000 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1'

[Dovecot] 143 STARTTLS/ 993 SSL/TLS query
by Voytek Eymont 09 Apr '11

09 Apr '11

I'm testing my new dovecot server with Thundirbird I can have it working on port 143 with STARTTLS, or on port 993 with SSL/TLS my uderstanding is that on 993 I get encrypted 'password and mail transfer' (yes ?) so what happens if I use 143 with STARTTLS, is that equivalent to port 993 if STARTTLS is used ? thanks for any insights.. -- Voytek

[Dovecot] Imap segfault on login with version 2.0.8 & 2.0.11
by Nicholas VonHollen 09 Apr '11

09 Apr '11

Hi everyone, I'm trying to upgrade/test our configuration files from Dovecot 1.2 to 2.0.11. I used the Dovecot config convert command, created a RHEL 5 x86_64 rpm, and tested it. I can connect, but once I login, the IMAP service segfaults. I've also reproduced this on version 2.0.8. I installed the debug RPM (for the stripped symbols), took a look at the core dump in gdb, and just got the _start method in ld_preload and a broken pointer in the backtrace. I tried to strace everything but the segfault doesn't happen then :-). I'm not sure what to do to get better information. I attached my client session, dovecot -n output, gdb trace, maillog, and the core dump. I published the RPMs I made at: http://c3205012.r12.cf0.rackcdn.com/dovecot-2.0.11-1_125.x86_64.rpm http://c3205012.r12.cf0.rackcdn.com/dovecot-debuginfo-2.0.11-1_125.x86_64.r… My platform is RHEL 5 with kernel 2.6.18 on x86_64. Is there anything else I can provide for more info? Thanks, Nick Nick VonHollen Rackspace Software Developer Desk: 540-443-2003 (internal 505-2003) Personal Cell: 757-710-7038

[Dovecot] restarting director
by Cor Bosman 08 Apr '11

08 Apr '11

Hi all, anyone having any problems with restarting the director? Every time I bring down 1 of the director servers, reboot it, or just restart it for whatever reason, im seeing all kinds of problems. Dovecot generally always gives me this error: Jan 20 22:49:55 imapdirector3 dovecot: director: Error: Director 194.109.26.173:444/right disconnected before handshake finished It seems the directors cant agree on forming a ring anymore, and this may be leading to problems with clients. I mostly have to resort to bringing down all directors, and restarting them all at once. Not really a workable solution. As an example, last night for a few hours we were getting complaints from customers about being disconnected, and the only obvious error in the log was the one above, after one of my colleagues had to restart a director because of some changes in the syslog daemon. After I restarted all directors withing a few seconds of each other, all complaints disappeared. Timo, i know ive asked similar questions before, but the answer just eludes me. If I have 3 director servers, and need to take one down and restart it, what is the proper method to reconnect the ring? In practice, I cant seem to work it out and I mostly end up with the above error until I just restart them all. Not fun with 20.000 clients connected. Cor

[Dovecot] Thunderbird 3.1 unable to delete subfolder of Trash under mdbox
by William Blunn 08 Apr '11

08 Apr '11

Thunderbird 3.1.9 over Windows 7. Dovecot 2.0.11 (2:2.0.11-0~auto+41 from http://xi.rename-it.nl/debian/ source on 8 Apr 2011) over Ubuntu 10.04 LTS. Trying to set up a Dovecot system with mdbox. But I also wanted to keep some Maildir. So I ended up with both mdbox and Maildir side-by-side and noticed an issue. On this system, Dovecot's global mail location is configured with maildir:~/Maildir I have a two users configured in a password-file passdb/userdb: One using the Dovecot global mail location (maildir:~/Maildir) the other with an override mail location (userdb_mail) of mdbox:~/mdbox (The only other configurations different to the default were to turn off the default system password passdb and userdb, and enable my local password-file-format passdb and userdb.) I have configured two IMAP accounts in Thunderbird 3.1.9, one to access each of the two users above. The test procedure is: In Thunderbird, create a folder at the top level (i.e. alongside Inbox), say "foo". In Thunderbird, delete the folder just created. This results in Thunderbird "moving" the folder to "Trash", resulting in a folder "Trash/foo". Up to this point, both the Maildir and mdbox users behave OK. Then in Thunderbird, delete the trashed folder "Trash/foo". At this point, things start to happen differently. With the Maildir user, the folder "Trash/foo" deletes successfully. But with the mdbox user, Thunderbird pops up an error: The current command did not succeed. The mail server for account <accountname> responded: Invalid mailbox name: Trash/foo/. The folder does disappear from the Thunderbird folder pane, but if Thunderbird is "prodded" to refresh what folders it thinks are there, then the folder reappears. If we check the user's mdbox directory, we can see that indeed the mailbox has not been deleted. Whatever I then do, I am unable to delete this folder in the mdbox user through Thunderbird. The only way I have found to safely delete the folder is to use "doveadm mailbox delete", but this requires root privilege on the server, which is not really a practical solution. It maybe a Thunderbird problem, but the question then arises: Why does it work under Maildir but doesn't work under mdbox? Any ideas? Bill

[Dovecot] fstat no such file or directory error
by Mark Dieterich 08 Apr '11

08 Apr '11

Periodically, we will have users IMAP sessions get hung. Their client sees a message like: The server responded: 'SERVERBUG] Internal error occurred. Refer to server log for more information On the server, we see the following in the logs: IMAP(<username>): Transaction log dovecot.index.log: duplicate transaction log sequence (37) IMAP(<username>): fscking index file dovecot.index IMAP(<username>): fstat() failed with index file dovecot.index: No such file or directory After the fstat message shows up, there doesn't appear to be anything on the user side that can be done to fix the problem. We've seen multiple instances where the file dovecot is complaining about not existing is visible, readable, and writable by the user in question, but dovecot is convinced it's not. The only way we've found to fix this issue is to kill off all user connections. When the user reconnects, then all appears to work fine. We have not found a way to recreate this problem. Some details: # 1.2.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-686 i686 Debian 5.0.8 Mail files are stored on NFS. All imap connections for a given user are are mapped to a particular server at any given time. We have a script in place that watches our logs for this order of events, so the problem self corrects relatively quickly. But it would certainly be nice not have this happen at all. Thanks, Mark -- ---------- I'd rather be burning carbohydrates than hydrocarbons

[Dovecot] shared folder: messages become invisible
by Burckhard Schmidt 08 Apr '11

08 Apr '11

Hello, after dealing with shared folder within version 2.0 rc* I started using it with a group of users. user1 shares a folder to user2. user2 has access to messages of this shared folder. After a "random" time (minutes up to several days) user2 doesn't see those messages anymore. user1 (the owner) hasn't changed anything inside this folder. All messages are still in place and normal visible for him. If user1 copies (whit TB) a messages into that folder user2 can see sometimes all messages again. But after a "random" time it happens again. user2 sees an empty shared folder. Deleting dovecot.index.log and dovecot.index.cache does not help. I have version 2.0.11 (2.0.10 same problem). mail_gid = sysdov mail_uid = sysdov namespace { inbox = yes list = yes location = prefix = separator = / subscriptions = yes type = private } namespace { list = yes location = maildir:%%h/maildir:CONTROL=~/control/FremdeOrdner/%%u:LAYOUT=fs prefix = FremdeOrdner/%%u/ separator = / subscriptions = no type = shared } mail_location = maildir:~/maildir:INDEX=/addons/index/%u:CONTROL=~/control:LAYOUT=fs I checked in a dialog: user1: 1 login user1 ... 1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS ACL RIGHTS=texk] Logged in 1 list "" "*" ... * LIST (\HasChildren) "/" "94ssl" #this one is shared to user2 * LIST (\HasNoChildren) "/" "94ssl/ansicht" #this one too user2: 1 login user2 ... 1 OK [CAPABILITY ... 1 list "" "*" ... * LIST (\HasChildren) "/" "FremdeOrdner/user1/94ssl" * LIST (\HasNoChildren) "/" "FremdeOrdner/user1/94ssl/ansicht" ... user1: 1 examine 94ssl * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 2 EXISTS # 2 messages * 0 RECENT * OK [UIDVALIDITY 1301570235] UIDs valid * OK [UIDNEXT 3] Predicted next UID * OK [HIGHESTMODSEQ 4] Highest 1 OK [READ-ONLY] Select completed. 1 examine 94ssl/ansicht * OK [CLOSED] Previous mailbox closed. * FLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-0) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 6 EXISTS # 6 messages * 0 RECENT * OK [UIDVALIDITY 1301570236] UIDs valid * OK [UIDNEXT 7] Predicted next UID * OK [HIGHESTMODSEQ 14] Highest 1 OK [READ-ONLY] Select completed. user2 1 examine FremdeOrdner/user1/94ssl * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 0 EXISTS # no message, should be 2 * 0 RECENT * OK [UIDVALIDITY 1301570944] UIDs valid * OK [UIDNEXT 6] Predicted next UID * OK [HIGHESTMODSEQ 11] Highest 1 OK [READ-ONLY] Select completed. 1 examine FremdeOrdner/user1/94ssl/ansicht * OK [CLOSED] Previous mailbox closed. * FLAGS (\Answered \Flagged \Deleted \Seen \Draft NonJunk unknown-0) * OK [PERMANENTFLAGS ()] Read-only mailbox. * 0 EXISTS # no message, shold be 6 * 0 RECENT * OK [UIDVALIDITY 1301570943] UIDs valid * OK [UIDNEXT 33] Predicted next UID * OK [HIGHESTMODSEQ 37] Highest 1 OK [READ-ONLY] Select completed. user1/control/94ssl/dovecot-uidlist: 3 V1301570235 N1 G8406fb358864944d710300000cd09d4f 1 :1301570819.M719509P910.suncom2,S=1319,W=1348 2 :1301585261.M338176P881.suncom2,S=23758,W=24220 user1/control/94ssl/ansicht/dovecot-uidlist: 3 V1301570236 N1 G3e8f0f00b862944d6f0300000cd09d4f 1 :1301570366.M22178P901.suncom2,S=1149,W=1173 2 :1301575917.M12924P1028.suncom2,S=1035,W=1055 3 :1301576897.M502460P1043.suncom2,S=1156,W=1183 4 :1301580697.M399644P1089.suncom2,S=1147,W=1174 5 :1285149220.M287482P15434.suncom2,S=1122,W=1149 6 :1301582382.M287792P1196.suncom2,S=1019,W=1039 user2/control/FremdeOrdner/user1/dovecot-uidvalidity: 4d946580 user2/control/FremdeOrdner/user1/dovecot-uidvalidity.4d946580 user2/control/FremdeOrdner/user1/94ssl/dovecot-uidlist: 3 V1301570944 N6 G9536eb178474944db10300000cd09d4f 3 :1301585261.M338176P881.suncom2,S=23758,W=24220 4 :1301570819.M719509P910.suncom2,S=1319,W=1348 user2/control/FremdeOrdner/user1/94ssl/ansicht/dovecot-uidlist: 3 V1301570943 N33 G5efdb6247f65944d880300000cd09d4f 21 :1301570366.M22178P901.suncom2,S=1149,W=1173 22 :1301575917.M12924P1028.suncom2,S=1035,W=1055 23 :1301576897.M502460P1043.suncom2,S=1156,W=1183 24 :1301580697.M399644P1089.suncom2,S=1147,W=1174 25 :1301582382.M287792P1196.suncom2,S=1019,W=1039 26 :1285149220.M287482P15434.suncom2,S=1122,W=1149 -- regards --- Burckhard Schmidt

[Dovecot] doveadm search doesn't update fts

Hello, Doveadm search is failing to update our Squat indexes. The search itself works fine but the dovecot.index.search* files remain unchanged. I tried: doveadm search -u test mailbox INBOX body sometext doveadm search -u test mailbox INBOX text sometext I also tried the exact syntax Timo expressed in an earlier post: doveadm search -A body asdf If I run the same search through IMAP, the index files update as expected. The searches finish with a clean exit status and nothing shows up in the logs. I upgraded from 2.0.0 to 2.0.11 but the problem remains. >From doveconf -n: plugin { fts = squat } protocol imap { mail_max_userip_connections = 16 mail_plugins = $mail_plugins fts fts_squat } Thank you, Tony

I am trying > not to chmod 777 every mailbox. I was going to write about the same problem. This got me over the hump: chmod 0600 /var/spool/mail/* All my user's mailboxes used to be group=mail mode=0660. I think these settings were left over from Solaris' mail.local: I can't reproduce these permissions now, even for new mailboxes. Maybe it's because the spool directory is now mode=1777 (not g+s mail). Not too keen on these permissions either, but it seems to work. Dovecot seems to transfer group permissions of the mailbox to its corresponding cache. If it can't set group ownership, you get the fatal error message above. If the original mailbox is mode 0600, dovecot is smart enough not to set group ownership. I couldn't find this information: shouldn't it be documented here? http://wiki2.dovecot.org/SharedMailboxes/Permissions This situation could also happen if a user is revoked from a group's membership. Would it be useful to make this a configurable behaviour whereby a chgrp() failure of cache files will fall back to chown'ing to user=owner, mode=0600 instead? Or just leave the user to scratch their head? Joseph Tam <tam(a)math.ubc.ca>

[Dovecot] LDA vs LMTP, Cyrus SASL, verbose_proctitle
by Joseph Tam 08 Apr '11

08 Apr '11

Is there a reason I should prefer LMTP over LDA for local delivery? Performance? Security? The Wiki doesn't differentiates LMTP vs LDA with respect to sendmail configuration, so am I correct that I just need to replace mail.local with dovecot-lda, which will choose LDA/LMTP based on dovecot.conf? Also, can I consolidate authentication by configuring dovecot to use what sendmail uses (Cyrus SASL) or vice versa? The Wiki hints this is in the works. Lastly, toggling verbose_proctitle seems to have no effect on the output of ps. Is verbose_proctitle broken for Solaris? Thanks, Joseph Tam <jtam.home(a)gmail.com>

Hi, I tried to use ATrpms (http://dl.atrpms.net/all/dovecot-2.0.11-1_126.src.rpm) to rebuild the rpms. It is shown the error message as following: configure: error: unrecognized option: --docdir=/usr/share/doc/dovecot-2.0.11 Try `./configure --help' for more information.

by tl511 07 Apr '11

07 Apr '11

I cant figure out permissions with Dovecot. I am new with this program and have tried setting the mail group to "mail" which is the group of my mailboxes which are located in /var/spool/mail. Here's the error I get. fs1 dovecot: imap(tl511insight): Error: chown(/home/tl511insight/mail/.imap/INBOX, -1, 12(mail)) failed: Operation not permitted (egid=504(tl511insight), group based on /var/mail/tl511insight) Apr 7 07:44:51 fs1 dovecot: imap(tl511insight): Error: mkdir(/home/tl511insight/mail/.imap/INBOX) failed: Operation not permitted Apr 7 07:44:51 fs1 dovecot: imap(tim): Error: chown(/home/tim/mail/.imap/INBOX, -1, 97(dovecot)) failed: Operation not permitted (egid=500(tim), group based on /var/mail/tim) Apr 7 07:44:51 fs1 dovecot: imap(tim): Error: mkdir(/home/tim/mail/.imap/INBOX) failed: Operation not permitted How do I give permissions to dovecot program to create these?

[Dovecot] dovecot: auth(default): Can't open configuration file /etc/dovecot/dovecot-sql.conf: Permission denied
by Kevin P. McDonough 05 Apr '11

05 Apr '11

Hello, I have been searching all day for help on an issue I am having after installing and just having begun to configure dovecot. Whenever I try to start the dovecot daemon I receive the following errors in the syslog: Apr 4 13:15:03 ***** dovecot: auth(default): Can't open configuration file /etc/dovecot/dovecot-sql.conf: Permission denied Apr 4 13:15:03 *****dovecot: dovecot: Fatal: Auth process died too early - shutting down Now, I have gone through the config file (see below) trying various settings for auth including running it as root and as vmail. I have tried a number of permutations for the permissions and ownership on the file specified above from 600 root -> 777 vmail and everything in between, yet always the same issue. If I rename the file and try to start dovecot it notices that the file is missing and gives an appropriate error. I cannot figure out how the permissions can be wrong on the file, I am starting to assume it is a problem elsewhere. (One other note, I was initially getting an error regarding the rawlog permissions, and just removed the rawlog part of the IMAP config to work around that). ---cut--- *****:~ # l /etc/dovecot/ total 160 drwxr-xr-x 2 root root 4096 Apr 4 14:18 ./ drwxr-xr-x 98 root root 12288 Apr 4 17:41 ../ -rw-r--r-- 1 root root 52110 Apr 4 14:18 dovecot.conf -rw-r--r-- 1 root root 51576 Mar 16 13:31 dovecot.conf~ -rw-r--r-- 1 root root 410 Feb 22 19:03 dovecot-db-example.conf -rw-r--r-- 1 root root 782 Feb 22 19:03 dovecot-dict-sql-example.conf -rw-r--r-- 1 root root 4986 Feb 22 19:03 dovecot-ldap-example.conf -rw-r--r-- 1 root root 5589 Apr 4 13:25 dovecot-sql.backup -rw------- 1 root root 5589 Mar 16 13:31 dovecot-sql.conf -rw-r--r-- 1 root root 5097 Feb 22 19:03 dovecot-sql-example.conf ---cut--- ---cut--- *****:~ # dovecot -n # 1.2.16: /etc/dovecot/dovecot.conf Error: setmntent(/etc/mtab) failed: Permission denied # OS: Linux 2.6.37.1-1.2-desktop i686 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3 pop3s ssl: no disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login first_valid_uid: 5000 last_valid_uid: 5000 first_valid_gid: 5000 last_valid_gid: 5000 mail_location: maildir:/var/vmail/%d/%n/Maildir mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/rawlog /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 lda: postmaster_address: postmaster(a)example.com mail_plugins: sieve quota mail_plugin_dir: /usr/lib/dovecot/modules/lda auth_socket_path: /var/run/dovecot/auth-master auth default: mechanisms: plain login passdb: driver: pam passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail plugin: quota: maildir sieve: ~/.dovecot.sieve sieve_dir: ~/sieve ---cut--- I just noticed that setmntent error above, I havent seen that anywhere else previously.

[Dovecot] squirrelmail doesn't display share

[Dovecot] imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed:

My dovecot directors (v2.0.8) had 3 instances of these yesterday: imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) master: Error: service(imap-login): child 17374 killed with signal 6 (core dumps disabled) imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) master: Error: service(imap-login): child 1780 killed with signal 6 (core dumps disabled) imap-login: Panic: file ioloop.c: line 35 (io_add): assertion failed: (fd >= 0) master: Error: service(imap-login): child 10349 killed with signal 6 (core dumps disabled) dovecot "assertion failed" normally scares me quite a bit, but I don't think this can be very bad, since it's only on the directors and we're not doing lmtp here yet.. More of a FYI, and please let me know if I should enable something to get better debug data if/when it happens again. -jf

[Dovecot] Master credentials for sieve

Is there a method for using master credentials for sieve only? We sometimes need to install/edit sieve script for some of our users. Currently, we just edit the files on the file server, but that doesn't appear the most sensible way for me

[Dovecot] Invalid old index files
by Reinhard Vicinus 05 Apr '11

05 Apr '11

Hi, i'm in the process of evaluating dovecot. I have a rather big testing environment with four dovecot director frontend instances and four dovecot backend instances. Mailboxes are all in mdbox format and stored on nfs. Indexes are stored locally. dovecot nfs setup for high performance is used (mmap_disable = no, dotlock_use_excl = yes, mail_nfs_storage = yes, mail_nfs_index = no). The remaining problem is, if i disable a backend server and the backend server which took over the connection already has some old index files, this index files aren't updated. If there aren't any index files all is fine and the index files are created anew. I can solve this by regularly deleting old index files via a cronjob. But i'm not sure if i made a configuration mistake and dovecot somehow can detect old index files automatically and invalidate them? Thanks in advance Reinhard

[Dovecot] Dsync & random delete problem
by Antoine Millet 04 Apr '11

04 Apr '11

Hello, I've updated my home mail server with dovecot 2.0.11 with idea of using dsync to synchronize two master servers (one at home behind an ADSL connection, and another in a DC with a gigabit connection). Dsync is launched every minutes by a cron job for each hosted mailboxes (in Maildir format). Obviously, a lock prevents to launch more than one dsync process at time. On a test mailbox, it worked perfectly, but when I decided to use it on my own mailbox: big drama :-). Some trashed messages reappear after the next sync, by dint of insisting, sometime it are duplicated. Occasionally, the synchronization has the desired effect, but messages reappear few hours later... So, my questions are: * Dsync is it supposed to be used to synchronize two mailboxes on continuously? * Are these problems known? I've found one thread about a random delete problem, so it seem to be? Do you need more informations to debug it? My informations: * Dovecot version: 2.0.11 * Distro: Debian Squeeze amd64 * FS: ext4 * Mailbox format: Maildir * Dsync command: "dsync -u {account} mirror ssh -i /var/vmail/sync/id_vmail -C {dest} dsync -u {account}" * Bug happen randomly, I haven't found a way to reproduce it. * Dovecot configuration: A part in particular is interesting? Thanks in advance, -- Antoine Millet http://inaps.org

[Dovecot] doveadm mailbox status - getting the size in bytes
by Patrick McLean 04 Apr '11

04 Apr '11

Hi, doveadm has an option to get the "vsize" of mailboxes, which is calculated by counting the number of linefeeds, but there does not appear to be way to simply get the size in bytes of a mailbox. I was wondering if there is something I am missing (I am using mdbox), or if not is it possible to implement this. Thanks

[Dovecot] dovecot ldap failed to recover
by Jan-Frode Myklebust 04 Apr '11

04 Apr '11

One of our backend pop/imap-server running dovecot v1.2.16 experienced some problems yesterday. It suddenly couldn't authenticate users anymore, flooding the logs with: pop3-login: Disconnected (auth failed, 1 attempts): user=<user1(a)example.com>, method=PLAIN, rip=192.168.42.15, lip=192.168.42.28 The problem seemed to start with this log entry: Mar 29 18:57:21 popimap1 dovecot: auth(default): ldap(userX(a)example.com,192.168.42.15): Connection appears to be hanging, reconnecting and this suspicious entry a few seconds later: Mar 29 18:57:41 popimap1 dovecot: auth(default): LDAP: Reply with unknown msgid 2 Afterward 18:57:21 it was unable to authenticate any users before I restarted the dovecot service. Also some of our postfix servers reported ldap lookup failures between 18:56-18:58, but then recovered. Looking at the ldap server side, we saw no problems logged, but netstat reports there being 3 active ldap sessions towards the dovecot server that failed yesterday, while the dovecot server only has 1: ldap1$ netstat -na |grep 192.168.42.28 tcp 0 0 192.168.43.2:389 192.168.42.28:44408 ESTABLISHED tcp 0 0 192.168.43.2:389 192.168.42.28:36464 ESTABLISHED tcp 0 0 192.168.43.2:389 192.168.42.28:60580 ESTABLISHED popimap1$ netstat -na| grep 192.168.43.2 tcp 0 0 192.168.42.28:60580 192.168.43.2:389 ESTABLISHED So it looks to us like there was some problem with either the network, or the ldap-server for a short periode, and that dovecot then wasn't able to recover from this. -jf

[Dovecot] install question
by Gerard Ranke 04 Apr '11

04 Apr '11

Dear list, I'm trying to build a dovecot-2.0.11 package for our systems, and so I would like to install it to a temporary directory. But when I use "gmake DESTDIR=/tmp/build install", instead of binaries, it's wrapper scripts that get installed for dovecot, doveconf and doveadm. When I install to the default location all is well. Does anybody know how how to install to a temp location? Thanks in advance for your answer! Best regards, Gerard Ranke

[Dovecot] Segmentation fault with vpopmail auth
by Samuel Montosa 04 Apr '11

04 Apr '11

Hi. I am new in the list. First, excuse my english. I am not native speaker. A few hours ago I had a problem with process dovecot-auth and vpopmail. Versions I had using, working, were: vpopmail 5.4.28 dovecot-1.1.12 I tried to compile dovecot-1.2.16. Compilation was well but in execution system said: kernel: dovecot-auth[2842]: segfault at 645f20 ip 0000000000645f20 sp 00007fff69bd3708 error 15 in dovecot-auth[645000+1000] and so. Then, I tried to recompile dovecot-1.1.12 (original version I had working) but system said the same. After investigation, I saw I had mixed of vpopmail versions. Problem was I had /home/vpopmail/lib/libvpopmail.so in my system. When this file is present, compilation of dovecot link dovocot-auth to dynamic library libvpopmail.so, but it is not necessary since I had my system working using vpopmail without this .so. What I recommend is to compile a fresh vpopmail. Now I am using vpopmail-5.4.32 (at now, stable version) and dovecot-1.2.16. First, compile vpopmail and make sure you purge /home/vpopmail/lib/ of libvpopmail.so. Fresh installations of vpopmail, from tar.gz (not from SVN) _doesn't_ build libvpopmail.so, so make sure this file doesn't exist before you compile dovecot. For me, library dependencies are: mymachine:/usr/local/src/dovecot-1.2.16# ldd src/auth/dovecot-auth linux-vdso.so.1 => (0x00007fff63df5000) libpam.so.0 => /lib/libpam.so.0 (0x00007f9f925e1000) libcrypt.so.1 => /lib/libcrypt.so.1 (0x00007f9f923aa000) libdl.so.2 => /lib/libdl.so.2 (0x00007f9f921a5000) librt.so.1 => /lib/librt.so.1 (0x00007f9f91f9d000) libc.so.6 => /lib/libc.so.6 (0x00007f9f91c3c000) /lib64/ld-linux-x86-64.so.2 (0x00007f9f927f7000) libpthread.so.0 => /lib/libpthread.so.0 (0x00007f9f91a1f000) I hope this helps. It was a strange "bug". Regards. -- Samuel Montosa

[Dovecot] Maildir
by Walt Shekrota 01 Apr '11

01 Apr '11

I noticed in Cyrus they seem to address maildir++ recognised by IMAP. I need to know does Dovecot recognise this format? Procmail has an ability to deliver mails to different folders which if unrecognised renders the whole process useless. Does Dovecot have a similar deliver method? Thanks. -Walt

[Dovecot] inotify and network/cluster filesystems
by Jan-Frode Myklebust 01 Apr '11

01 Apr '11

(dovecot v1.2.16) I've notice the log notices about increasing /proc/sys/fs/inotify/max_user_instances on my servers, and started wondering if inotify works for network/cluster filesystems.. I found this: http://www.ibm.com/developerworks/forums/thread.jspa?threadID=311194 which says that there's no mechanism for one node to tell another node that a directory changed for GPFS.. And I would assume the same applies for NFS and other network filesystems. (Yes I know, we should use director to make users sticky to one host -- but we're not yet ready for that for lmtp). So, are there any recommendations for what settings one should use for for filesystems where inotify woun't work ? Are there settings for disabling it (without recompiling)? And does mailbox_idle_check_interval happen in addition to inotify, so that clients will be notified even with a broken inotify ? -jf

[Dovecot] Sieve: unknown tagged argument ':create' for the fileinto command
by mailing＠securitylabs.it 01 Apr '11

Hello, I've upgraded from dovecot 1.2.x with sieve to dovecot 2.0.11 with sieve. I've noticed that folders are no more created at delivery time now. I've read that I have to do two things: lda_mailbox_autocreate = yes in dovecot.conf and fileinto :create in the sieve script. Now the error message I receive is: error: unknown tagged argument ':create' for the fileinto command (reported only once at first occurence). My sieve script: require ["date", "variables", "fileinto"]; if header :contains "subject" "Bacula:" { if currentdate :matches "month" "*" { set "month" "${1}"; } if currentdate :matches "year" "*" { set "year" "${1}"; } fileinto :create "INBOX.Bacula.${month}-${year}"; } else { # The rest goes into INBOX # default is "implicit keep", we do it explicitly here keep; } My dovecot conf: papua:/usr/local/bin# dovecot -n # 2.0.11: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.1 auth_cache_negative_ttl = 2 mins auth_cache_size = 1000 M auth_cache_ttl = 2 mins auth_mechanisms = plain cram-md5 apop auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@& disable_plaintext_auth = no first_valid_uid = 100 last_valid_uid = 105 lda_mailbox_autocreate = yes lock_method = dotlock log_timestamp = "%Y-%m-%d %H:%M:%S " login_greeting = Server ready. mail_fsync = never mail_gid = Debian-exim mail_location = maildir:~/Maildir mail_privileged_group = Debian-exim mail_uid = Debian-exim 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 namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = /usr/local/etc/dovecot-sql.conf driver = sql } plugin/mail_log_events = delete expunge plugin/mail_log_group_events = plugin/quota = maildir plugin/quota_warning = storage=80%% /usr/local/bin/dovecot-quota-warning.sh 80 plugin/quota_warning2 = storage=90%% /usr/local/bin/dovecot-quota-warning.sh 90 plugin/sieve = ~/.dovecot.sieve protocols = imap service auth { unix_listener auth-userdb { group = Debian-exim mode = 0600 user = Debian-exim } } service imap-login { client_limit = 256 process_limit = 128 process_min_avail = 3 service_count = 1 } service imap { drop_priv_before_exec = yes process_limit = 256 vsz_limit = 256 M } service pop3-login { client_limit = 256 process_limit = 128 process_min_avail = 3 service_count = 1 } service pop3 { drop_priv_before_exec = yes process_limit = 256 vsz_limit = 256 M } ssl_cert =</usr/local/etc/dovecot.crt ssl_key =</usr/local/etc/dovecot.key userdb { args = /usr/local/etc/dovecot-sql.conf driver = sql } protocol imap { mail_max_userip_connections = 10 mail_plugins = " notify quota imap_quota mail_log" } protocol lda { mail_plugins = quota sieve postmaster_address = postmaster(a)me.com }

[Dovecot] Mail_location and formats
by Walt Shekrota 31 Mar '11

31 Mar '11

Hi, Ok I know that the Maildir hierarchical structure works because I saw it intermittantly in my setup. At times I could look at ALL folders in my client. mail_location = maildir:~/Maildir:LAYOUT=fs http://wiki1.dovecot.org/MailLocation/Maildir this says 1.1 only? My maildir folder has a collection of maildir folders ie each has cur new tmp folders. As an experiment I took the cur new tmp out of my INBOX folder and put it in the root of Maildir. This worked with dovecot using the inbox only or the standard maildir++ format. Although it would not see the old mail in the folder not sure why. mail_location = maildir:~/Maildir This setup also ignores the remainder of folders. I know the dovecot support of maildir is shakey due to standards compliance but this is crazy ... and unusable. Does ANYONE have a working maildir setup in the hierarchical layout? Maildir/ inbox mail-sent outbox otherfolder Fred Sue Thanks. -Walt

[Dovecot] POP3 connection issue & SASL not compiled in
by sunhux G 31 Mar '11

31 Mar '11

After I've configured dovecot for SSL according to the info given in the link below: https://access.redhat.com/kb/docs/DOC-6671 (tried both POP3 & secure POP3 & got the same result) I tested POP3 access from my unblocked (no firewall rule for outgoing) broadband PC's Outlook to connect to the postfix/dovecot server & got the following : Tasks Status ===================== ======== Establish network connection Completed Find outgoing mail server (SMTP) Completed Find incoming mail server (POP3) Completed Log onto incoming mail server (PO... Send test e-mail message Completed (yep, this email was received in postfix mailbox) & seconds later, the following messages returned: Log onto incoming mail server (POP3): The specified server was found, but there was no response from the server. Please verify that the port and SSL information is correct. To access these settings close this dialog, then click More Settings and click on the Advanced tab. Find incoming mail server (POP3): Outlook could not connect to the incoming mail server (POP3). The problem could be the server name or port, or your server may not support SSL. Verify your port and SSL settings in More Settings under the Advanced tab. Q1: What do I need to provide to this list for further troubleshooting? Q2: I have the following log entry in /var/log/mailog : Mar 31 10:48:36 hostname postfix/smtpd[22258]: warning: smtpd_sasl_auth_enable is true, but SASL support is not compiled in Is this related to my POP3 connection issue? Q3: Is the following related to the sasl issue in Q2 & the POP3 connection issue ?

[Dovecot] How to grant a kerberos ticket after successful imap authentication from dovecot
by André Rodier 31 Mar '11

31 Mar '11

Hello everybody, I hope this question is appropriate for this list. Apologies if not. I am running a set of virtual machines under debian 6, to build a mail/collaboration server. I am mainly using dovecot, postfix, openldap and heimdal. Mails are stored using maildir, on a NFSv4 share. My users are system users, but using LDAP and libpam-ldap and libnss-ldap for caching credentials information. Everything is working as expected, well, /almost/. Since NFS is using kerberos, by defaults, my users are not able to access their mail storage if they have not received their kerberos ticket. For instance, if I do nothing, this is the errors I have from dovecot when trying to logon using any imap client: Mar 31 09:33:07 titan dovecot: imap-login: Login: user=, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Mar 31 09:33:07 titan dovecot: dovecot: Fatal: chdir(/home/emails/team/arodier/) failed: Permission denied (euid=1003(arodier) egid=1001(red2team) missing +x perm: /home/emails) Mar 31 09:33:07 titan dovecot: dovecot: child 5089 (imap) returned error 89 (Fatal failure) However, if I just login on a console for the user "/arodier/", I see that I have received a ticket, and I can see it with klist: Credentials cache: FILE:/tmp/krb5cc_1001_ywvktf Principal: arodier(a)RED2.SRV Issued Expires Principal Mar 31 09:25:55 Mar 31 19:25:53 krbtgt/RED2.SRV(a)RED2.SRV Mar 31 09:25:57 Mar 31 19:25:53 nfs/ananke.red2.srv(a)RED2.SRV Once I have simply logged myself on a console, I can access my emails using any IMAP client. The question is: How should I configure libpam (or dovecot ?) to initialise/receive a kerberos ticket after successful authentication ? Thanks for your answers.

[Dovecot] debugging mail_location issues
by Walt Shekrota 31 Mar '11

31 Mar '11

Type of Maildir structure I am using came from KDE. No '.'s just folders. something like Maildir/ INBOX mail-sent outbox other where each has cur new and tmp folders. if I access this directory with IMAP it creates cur new and tmp in the root. ie Maildir/ INBOX cur new tmp mail-sent outbox other This implies to me 1. it finds the Maildir directory 2. it apparently does not have access to the directories like INBOX so it makes its own in the root? or is this a side effect I'm misunderstanding? The resulting IMAP session shows an empty INBOX only (this must be the cur new tmp it added) The real INBOX is not accessible but still intact. In a session this morning I could access all the folders just not the real INBOX. INBOX was as is here empty with cur new tmp in the root of the Maildir folder. This behavior makes no sense. I'm using the hierarchical structure as pointed to in. http://wiki1.dovecot.org/MailLocation/Maildir It appears my grief surrounds dovecot's detection of mailbox. This is kind of what I said days ago. Setting up requires you to know expected states. Something in my environmment I haven't been able to identify (yet) is influencing recognising that hierarchical maildir structure. -Walt

Hi, small question: Will the WiKi of the version 2 be updated shortly? Many things are not right at all. This would be really very nice. Many thanks in advance. -- Mit freundlichen Grüßen, Jim Knuth P.S.: Bitte senden Sie KEINE HTML-Mails! Zufallszitat: Das Schweigen von gestern rechtfertigt nie das Schweigen von heute. (Otto Schily)

[Dovecot] Message file prefetching to memory
by Timo Sirainen 31 Mar '11

31 Mar '11

I added a new mail_prefetch_count setting to Dovecot v2.1 (http://hg.dovecot.org/dovecot-2.1/) Its main purpose is to avoid unnecessary latency while waiting for replies from remote server with imapc, i.e. instead of doing (FETCH, wait, FETCH, wait, ...) it can do (FETCH, FETCH, .., wait). For the same reason it's also going to be very useful once I add support for key-value databases / other high latency cloud filesystems. It also works with Maildir, single-dbox and cydir backends by calling posix_fadvise(POSIX_FADV_WILLNEED) for the files. This syscall is apparently only implemented by Linux. It should tell the kernel to start reading the files from disk to page cache. By calling this for multiple files, it should help the kernel optimize disk I/O. For example if 10 files are prefetched, the kernel might figure out that it should read them in a different order to avoid extra disk seeks. Perhaps it also does something useful with NFS, I don't know. I'm not sure if it would be a good idea to use this for mbox or multi-dbox files, since they already have multiple messages in same file so kernel probably already did some prefetching. With mdbox I guess it could be useful if the message file changes.. This optimization currently works only for FETCH command (and POP3 RETR and TOP). SEARCH/THREAD/SORT commands will hopefully implement it soon also. I'd be interested in knowing what the effects of this setting are if anyone tests this some day.
