[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
by metro_domain_admin＠fastmail.fm 08 Apr '11

08 Apr '11

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. I checked `./configure --help', it did contain the '--docdir' option. I don't know how to fix it. Then I tried to remove ' --docdir=%{_docdir}/%{name}-%{version} \' and rebuild it again. It is shown another error message as following: mv: cannot stat `/var/tmp/dovecot-2.0.11-1_126-root//usr/share/doc/dovecot-2.0.11': No such file or directory I tried to modify dovecot.spec again, replace 'mv $RPM_BUILD_ROOT/%{_docdir}/%{name}-%{version} %{_builddir}/%{name}-%{version}/docinstall ' with 'mv $RPM_BUILD_ROOT/%{_docdir}/%{name} %{_builddir}/%{name}-%{version}/docinstall' and rebuild it again. Antoher error shown 'File must begin with "/": %{_initddir}/dovecot', therefore I add '%define _initddir /etc/rc.d/init.d' Finally, I can rebuild the RPMS, but it is shown error message again while I install RPMS: [root@testmail SPECS]# rpm -ivh ../RPMS/x86_64/dovecot-2.0.11-1_126.x86_64.rpm Preparing... ########################################### [100%] 1:dovecot ########################################### [100%] /var/tmp/rpm-tmp.13056: line 3: syntax error near unexpected token `fi' /var/tmp/rpm-tmp.13056: line 3: `fi' error: %post(dovecot-2.0.11-1_126.x86_64) scriptlet failed, exit status 2 Please advise me how to fix the problem and thank you in advance. -- Best Regards, Bruce

[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.

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

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.

[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).

[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?

[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

[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.

[Dovecot] v1.2.12 and debug
by Walt Shekrota 30 Mar '11

30 Mar '11

Is there some kind of extended debug that might show why my maildir is not foundat login? It has worked off and on, once briefly today then no more. I'm going around twiddling knobs guessing at this point which is foolish. I need some real bread crumbs to indicate what is going wrong. I've tried all kinds of .conf file ... example file etc. I figured using the least number of settings should get me somewhere but I still have no luck. I'd love to just give up and load that PPA for 2.x but I have no idea what package to install in debian. (I have the PPA update) Thanks. -Walt

In 1.2.12 or there abouts how do changes in the dovecot.conf happen? After doing the sig HUP I have noted there is generally a delay in the recognition of items in my .conf. An example I had logging set off, turned it on and it was several restarts before I again saw logging? This delay is driving me nuts in trying to figure out what needs to change. Thanks. -Walt

[Dovecot] migrating to dovecot
by Alexandre Chapellon 30 Mar '11

30 Mar '11

Hello, I am trying to setup a migration scenario from an proprietary solution to dovecot IMAP/POP3. Whereas am only at the strating point, things appear quite complicated because of the following reasons: - The proprietary solution uses special/own/proprietary mailbox format (wich is more like maildir but is not maildir) - I don't have direct access to the filesystem where the mails are stored. The best I could do would be a snapshots of the filesystem - I have about 1,5TB of mail data. - Having users to be forced to empty their mailbox before migration or re-download their whole mailbox after migration would be something hard for me to present as a correct option. Am looking for advices that would avoid me loosing time searching in bad directions. Or even point me to a miraculous tool thatdoes all magic while i have a beer :) Best regards. -- horoa: la voie est libre

[Dovecot] file permissions
by Walt Shekrota 29 Mar '11

29 Mar '11

Dovecot 1.2.12 maildir format using :LAYOUT=fs (my Mail dir came from KDE) I can't remember the permissions of the /Mail/ directory because I haven't been concerned with it too much until now. I think they were user:user or user:mail. Now a new mail ends up 600 root:mail. (in alternate directories) When I start my mutt client to the imap server it gets an error for any folder containing a root:mail new mail file. I think the root ownership is a procmail side effect? If I chmod 760 Mail/folder/* (then the new emails show in dovecot without the access error) It appears mail comes to the INBOX fine just not individual folders On the initial access, dovecot gets a "missing +r perm" or "+x" in the log. 1: What permission structure should permeate my Mail dir? 2: What might affect the incoming mail file getting wrong permissions/ownership? I'm thinking the later may be a procmail issue unless it is related to initial incorrect permissions? Thanks for any insight. -Walt

[Dovecot] Trouble with password scheme module
by Ian R. Justman 29 Mar '11

29 Mar '11

Hi, all. About two and a half years ago, I wrote a hack to add an additional MD5-based password scheme to Dovecot, but I wrote it as a hack to src/auth/password_scheme.c since it was relatively easy to do, and I needed to get a machine running since the machine I was replacing, a Sun Ultra 5 running Post.Office, had dying hard drives. Now, I'm actually sitting down and adapting it as a module and am having trouble getting it to work. The code tarball itself can be picked up here: http://www.ian-justman.com/code/dovecot/password_scheme_po_smd5.tar.gz Before I continued, I made sure that a system-level account worked: # telnet <server IP> 110 Trying <server IP>... Connected to <server IP>. Escape character is '^]'. +OK Dovecot ready. user <username> +OK pass <password> +OK Logged in. quit +OK Logging out. Connection closed by foreign host. I then enabled the module, which introduces the password scheme "PO-SMD5". I have Dovecot's default scheme set to SMD5. If I get a password hash whose value has a {PO-SMD5} tag on it, the session looks like the following: # telnet <server IP> 110 Trying <server IP>... Connected to <server IP>. Escape character is '^]'. +OK Dovecot ready. user <user with PO-SMD5 password> +OK pass <user's password> -ERR Authentication failed. quit +OK Logging out Connection closed by foreign host. The following entry is deposited into the system log: Mar 28 17:44:51 <hostname> dovecot: auth: Error: sql(<username>,<server IP>): Unknown scheme PO-SMD5 However, when I try using an account covered by the system (which does work when the plugin isn't loaded in dovecot.conf), the session looks like the following: mikuru# telnet <server IP> 110 Trying <server IP>... Connected to <server IP>. Escape character is '^]'. +OK Dovecot ready. user <user with system password> +OK pass <user's password> Connection closed by foreign host. The following entry is deposited into the system log: Mar 28 17:45:13 <hostname> dovecot: pop3: Error: dlopen(/usr/local/lib/dovecot/lib_password_scheme_po_smd5.so) failed: /usr/local/lib/dovecot/lib_password_scheme_po_smd5.so: Undefined symbol "password_scheme_unregister" Otherwise, the patch I developed under 1.x applies cleanly to 2.0.x's password_scheme.c and works perfectly as a builtin. This work was done under FreeBSD 8.1-RELEASE amd64. Any ideas? --Ian. -- Ian R. Justman UNIX hacker. Anime fan. Any questions? ianj (at) ian-justman.com

[Dovecot] dovecot auth password mismatch
by david＠davidwbrown.name 28 Mar '11

28 Mar '11

Hello dovecot gods, after using Postfix with webmail for 8 years the new gen of email smartphones forces me to consider using IMAP. Actually, for several months I was successfully using IMAP. I believe the reason why IMAP worked previously (before migrating to the Cloud) the hosting server and the client machines were considered local by the system. Now, I have moved everything to a Cloud service. And, now attempts to use my Ubuntu Evolution or iPhone generates the following error condition in my logs: dovecot: auth(default): client in: AUTH 1 PLAIN service=imap lip=xxx.yyy.www.zzz rip=75.214.160.72 lport=143 rport=59107 resp=AGRhdmlkAGx1dGVmaXNr dovecot: auth(default): passwd(kilroy,75.214.160.72): lookup dovecot: auth(default): passwd(kilroy,75.214.160.72): Password mismatch dovecot: auth(default): passwd(kilroy,75.214.160.72): CRYPT(mypass) != 'x' dovecot: auth(default): new auth connection: pid=15522 dovecot: auth(default): client out: FAIL 1 user=kilroy ******************* dovecot -n ******************* 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.34.1-rscloud x86_64 Ubuntu 10.04.2 LTS log_timestamp: %Y-%m-%d %H:%M:%S disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_location: maildir:~/Maildir mbox_write_locks: fcntl dotlock auth default: realms: myname.name, hisname.name, hername.name default_realm: myrealm.com username_format: %n verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd userdb: driver: passwd

[Dovecot] Errors logged from 2.0.11
by Andreas Kossack 28 Mar '11

28 Mar '11

Hi all, we use dovecot 2.0.11 with local (LDAP based) users and see (occasionally) error messages like "Mar 15 09:29:26 MailServ local3:err|error dovecot: imap(xxxx): Error: creat(/dovecot.mailbox.log) failed: Permission denied (euid=1985(xxxx) egid=219(yyyy) stat() failed: No such file or directory, euid is not dir owner) but all (filesystem) permissions are correct and the user doesn't report any errors. All works as expected. What can be the reason for such messages? -- Mit freundlichen Grüßen A.

[Dovecot] IMAP move extension support
by Nikolay Shopik 28 Mar '11

28 Mar '11

Hi Timo, Any chance we could get IMAP move extension support in Dovecot? http://tools.ietf.org/html/draft-krecicki-imap-move-01 This is now landed in Thunderbird trunk, so it will be great to have server to test and use with :). Thanks

[Dovecot] Regression in settings-parser.c (dovecot 2.0.11)
by Michal Hlavinka 28 Mar '11

28 Mar '11

Hi, one Fedora user sees regression in dovecot 2.0.11 (compared to prev. 2.0.9). There was change recently: http://hg.dovecot.org/dovecot-2.0/diff/bc77e80947c0/src/lib-settings/settin… which adds call to settings_find_key_nth(...., &parent_def,...). This function can set parent_def to NULL, but there is no check for this situation in the code. So on next line if (parent_def->type !=... dovecot crashes. We've tested simple fix: if (parent_def==NULL) return FALSE; and everything was working again. Michal Backtrace of the crash: Program received signal SIGSEGV, Segmentation fault. settings_find_key_nth (ctx=0x99e4050, key=0x99c4330 "plugin//etc", n=0xbff9bdac, def_r=0xbff9bda8, link_r=0xbff9bda4) at settings-parser.c:696 696 if (parent_def->type != SET_STRLIST) (gdb) p parent_def $1 = (const struct setting_define *) 0x0 (gdb) bt #0 settings_find_key_nth (ctx=0x99e4050, key=0x99c4330 "plugin//etc", n=0xbff9bdac, def_r=0xbff9bda8, link_r=0xbff9bda4) at settings-parser.c:696 #1 0x004f9ce5 in settings_find_key_nth (ctx=0x99e4050, key=0x99c4318 "plugin//etc/dovecot", n=0xbff9be1c, def_r=0xbff9be18, link_r=0xbff9be14) at settings-parser.c:693 #2 0x004f9ce5 in settings_find_key_nth (ctx=0x99e4050, key=0x99c42f8 "plugin//etc/dovecot/users", n=0xbff9beb4, def_r=0xbff9bebc, link_r=0xbff9beb8) at settings-parser.c:693 #3 0x004f94fd in settings_parse_keyvalue (ctx=0x99e4050, key=0x99c42f8 "plugin//etc/dovecot/users", value=0x99c42f2 "yes") at settings-parser.c:760 #4 0x004fa270 in settings_parse_line (ctx=0x99e4050, line=0x99c42d8 "plugin//etc/dovecot/users=yes") at settings-parser.c:862 #5 0x00dededa in set_line (ctx=0x99cd468, input=0xbff9c100, user_r=0xbff9c04c, error_r=0xbff9c0fc) at mail-storage-service.c:134 #6 user_reply_handle (ctx=0x99cd468, input=0xbff9c100, user_r=0xbff9c04c, error_r=0xbff9c0fc) at mail-storage-service.c:227 #7 mail_storage_service_lookup (ctx=0x99cd468, input=0xbff9c100, user_r=0xbff9c04c, error_r=0xbff9c0fc) at mail-storage-service.c:843 #8 0x00deeaae in mail_storage_service_lookup_next (ctx=0x99cd468, input=0xbff9c100, user_r=0xbff9c0ac, mail_user_r=0xbff9c0a8, error_r=0xbff9c0fc) at mail-storage-service.c:968 #9 0x0805f2e7 in client_create_from_input (input=<value optimized out>, ---Type <return> to continue, or q <return> to quit--- login_client=0x99ce810, fd_in=11, fd_out=11, input_buf=0xbff9c0e0, error_r=0xbff9c0fc) at main.c:202 #10 0x0805f5dd in login_client_connected (client=0x99ce810, username=0x99c409b "sjoerd", extra_fields=0x99c4110) at main.c:267 #11 0x0051606f in master_login_auth_finish (client=0x99ce810, auth_args=<value optimized out>) at master-login.c:206 #12 0x005163c2 in master_login_auth_callback (auth_args=0x99c410c, errormsg=0x0, context=0x99ce810) at master-login.c:374 #13 0x00516d3e in master_login_auth_input_user (auth=0x99cdcd8) at master-login-auth.c:239 #14 master_login_auth_input (auth=0x99cdcd8) at master-login-auth.c:359 #15 0x0052cc72 in io_loop_call_io (io=0x99cea10) at ioloop.c:384 #16 0x0052ded3 in io_loop_handler_run (ioloop=0x99cc390) at ioloop-epoll.c:213 #17 0x0052cbf0 in io_loop_run (ioloop=0x99cc390) at ioloop.c:405 #18 0x005181fb in master_service_run (service=0x99cc2e0, callback=0x805f100 <client_connected>) at master-service.c:478 #19 0x0805fb0d in main (argc=1, argv=0xbff9c4c4) at main.c:375

[Dovecot] FTS Compound Search
by duonut 28 Mar '11

28 Mar '11

Hi I use roundcube as the webmail fronted to a dovecot server. It currently has squat enabled. When round cube performs a search, it does a compound search even if only one field is selected. >From another thread i read, dovecot in the v1 period did not support compound searches for squat. Does the latest version of V2 support compound searches with fts squat? If not, does fts with solr support compound searches? -- View this message in context: http://old.nabble.com/FTS-Compound-Search-tp31241908p31241908.html Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] Dovecot 2.0.9: Thunderbird 3.1.9: Very slow while open sent folder with many (4k>) mails
by Denny Schierz 27 Mar '11

27 Mar '11

hi, one customer told us, that he has performance problem in his Thunderbird 3.1.9, while open his sent folder, which has round about 4000 mails in it, and 20k in his Inbox. For example TB, tries to sync the sent-folder list (over SSL) from the sent folder for now over 15min. In the log, I can't see any strange things, so for me, Dovecot works ok. Maybe, I should use better cache options? Now he tries to move many messages to separate folders, but thats also a bit slow. So, is it a TB problem, with so many messages?

[Dovecot] How can I view these email files?
by Phill Edwards 27 Mar '11

27 Mar '11

I messed up my email today through a combination of stuff-ups with procmail and dovecot. The result was that I ended up delivering some email messages to the root Maildir folder instead of the sub-folders. The files are in the correct format but have names like msg.3BXE, msg.2BXE etc. Of course these don't show up in my IMAP client so I can't read them. Does anyone know a way I can point some sort of email client at these to read them? Or a way to transfer them under Maildir/new so that I can read them as part of my normal inbox?

[Dovecot] Multiple versions of Dovecot installed
by Phill Edwards 26 Mar '11

26 Mar '11

I have had to rebuild my 64-bit CentOS 5 email server and after installing dovecot rpms (using yum) I seem to have multiple versions installed: dovecot-1.1.20-1_98.el5 - from ATrpms repo dovecot-1.0.7-7.el5 - from CentOS repo dovecot-sieve-0.1.18-6.1.el5 - from ATrpms repo I have tried to install just the ATrpms version but when I do "yum install dovecot" the CentOS one always gets pulled in as well. Is this normal, or does it indicate that something has gone wrong in the installation process? I'm having an issue with Dovecot sieve because it can't find a sieve plugin in /usr/lib64/dovecot/lda/. However, there is one in /usr/lib/dovecot/lda/. Do I have some sort or 32-bit/64-bit mismatch?

Hi help is preciated, PROBLEM The dovecot-ldap.conf of "proxy server A" is working when the "host" attribute is the FQDN of other server: pass_attrs = uid=user,userPassword={SSHA}password,\ =proxy_maybe=,maildrop=host,=port=143,=destuser=%u,=starttls=any-cert pass_filter = (&(objectClass=posixAccount)(uid=%u)) CASES When the "host" attribute is the "FQDN of server A" dovecot imap-login start and infinite loop which swallow all RAM, and process are showing many connections although is just 1 test user connected.

[Dovecot] mdbox, quota, ns, maildir quota?
by Brandon Lamb 26 Mar '11

26 Mar '11

Hello, I pasted my config below, hoping someone can point out something obvious. In my dovecot.log I am seeing: Warning: quota: Namespace '' is not Maildir, skipping for Maildir++ quota I am using mysql userdb_* and passing maildir:~/maildir or mdbox:~/mdbox for mail. When its maildir its fine, I had that originally then used dsync to convert to mdbox, updated mysql entry to point to mdbox:~/mdbox and now I keept getting those quota errors. It IS possible to have mixed environment still correct? Some users can be maildir and some can be mdbox since Im using the per-user userdb options? Any hints here? I would swear this was all working on a different server I had setup but Im no longer employed there so I cant peek at the config =P Thanks for any help or tips Brandon ------------------------------------------------------------------------------- root@mail1:~# dovecot -n # 2.0.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.37-2-amd64 x86_64 Debian wheezy/sid auth_cache_negative_ttl = 30 secs auth_cache_size = 4 k auth_cache_ttl = 30 secs auth_default_realm = greencrane.com auth_mechanisms = plain login auth_username_format = %Lu auth_verbose = yes auth_worker_max_count = 60 base_dir = /var/run/dovecot debug_log_path = /var/log/dovecot/debug.log default_client_limit = 1024 default_internal_user = mail default_login_user = mail deliver_log_format = %s from %f %$ dict/expire = mysql:/etc/dovecot/conf.d/dovecot-dict-expire.conf.ext disable_plaintext_auth = no first_valid_gid = 8 first_valid_uid = 8 info_log_path = /var/log/dovecot/info.log last_valid_gid = 8 last_valid_uid = 8 log_path = /var/log/dovecot/dovecot.log log_timestamp = "%Y-%m-%d %H:%M:%S " login_log_format = %s login_log_format_elements = (%u) (%r) mail_access_groups = mail mail_fsync = never mail_gid = 8 mail_location = maildir:~/maildir mail_log_prefix = "%Ls <%u>: " mail_max_userip_connections = 4 mail_plugins = quota expire mail_privileged_group = mail mail_uid = 8 mailbox_idle_check_interval = 1 mins maildir_very_dirty_syncs = yes passdb { args = /etc/dovecot/conf.d/dovecot-sql.conf.ext driver = sql } plugin/auth_socket_path = /var/run/dovecot/auth-master plugin/autocreate = Trash plugin/autocreate2 = Sent plugin/autocreate3 = Drafts plugin/autocreate4 = Spam plugin/autosubscribe = Trash plugin/autosubscribe2 = Sent plugin/autosubscribe3 = Drafts plugin/autosubscribe4 = Spam plugin/quota = maildir:User quota plugin/quota_warning = storage=95%% quota-warning 95 %u plugin/quota_warning2 = storage=80%% quota-warning 80 %u protocols = imap pop3 service auth { executable = /usr/local/libexec/dovecot/auth unix_listener auth-client { group = mail mode = 0666 user = mail } unix_listener auth-master { group = mail mode = 0666 user = mail } unix_listener auth-userdb { group = mail mode = 0666 user = mail } vsz_limit = 512 M } service dict { unix_listener dict { group = mail mode = 0666 } } service imap-login { chroot = login client_limit = 512 executable = /usr/local/libexec/dovecot/imap-login process_limit = 20 process_min_avail = 4 service_count = 0 user = dovecot vsz_limit = 128 M } service imap { drop_priv_before_exec = no executable = /usr/local/libexec/dovecot/imap vsz_limit = 512 M } service pop3-login { chroot = login client_limit = 512 executable = /usr/local/libexec/dovecot/pop3-login process_limit = 20 process_min_avail = 4 service_count = 0 user = dovecot vsz_limit = 128 M } service pop3 { drop_priv_before_exec = no executable = /usr/local/libexec/dovecot/pop3 vsz_limit = 512 M } service quota-warning { executable = script /etc/dovecot/quota-warning.sh user = mail } ssl_cert = </etc/dovecot/ssl/dovecot-cert.pem ssl_key = </etc/dovecot/ssl/dovecot-key.pem userdb { driver = prefetch } userdb { args = /etc/dovecot/conf.d/dovecot-sql.conf.ext driver = sql } valid_chroot_dirs = /mail verbose_proctitle = yes protocol lda { auth_socket_path = /var/run/dovecot/auth-userdb info_log_path = /var/log/dovecot/deliver.log lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes log_path = /var/log/dovecot/deliver.log mail_fsync = optimized mail_plugin_dir = /usr/local/lib/dovecot mail_plugins = quota expire trash autocreate postmaster_address = postmaster(a)greencrane.com quota_full_tempfail = yes rejection_reason = Your message to <%t> with subject of <%s> was automatically rejected:%n%r rejection_subject = Mailbox Full: %s sendmail_path = /usr/sbin/exim } protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep imap_id_log = * imap_logout_format = bytes=%i/%o imap_max_line_length = 64 k mail_max_userip_connections = 20 mail_plugin_dir = /usr/local/lib/dovecot mail_plugins = quota expire imap_quota autocreate trash } protocol pop3 { mail_max_userip_connections = 2 mail_plugin_dir = /usr/local/lib/dovecot mail_plugins = quota expire pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_enable_last = no pop3_lock_session = no pop3_logout_format = retr=%r/%b, del=%d/%m, size=%s pop3_no_flag_updates = yes pop3_reuse_xuidl = no pop3_save_uidl = yes pop3_uidl_format = %g }

by Frank Bonnet 26 Mar '11

26 Mar '11

Hello Is there a way to restrict access to Dovecot server during mailboxes convertion ? I need dovecot to be running to convert mailboxes from a format to another, but I would like to block all our LAN clients until the end of convertion. If there is no internal Dovecot mechanism I will use some firewall rule on the server. Thanks

[Dovecot] lda_mailbox_autocreate and lda_mailbox_autosubscribe
by Frank Bonnet 25 Mar '11

25 Mar '11

Hello I use real unix users on the mailhub and I would like to automate home directories creation for new users. I found lda_mailbox_autocreate and lda_mailbox_autosubscribe statements in 15-lda.conf file ( dovecot 2.0.11 ) which seem to be the right things for me :-) I use Postfix 2.8.1 with Dovecot LDA mailbox_command = /usr/local/libexec/dovecot/dovecot-lda All Mailboxes are located in /user/$USER/mail/ Does those two statements means that if a home directory does not exists it will be created at the first login of the new user ? I mean if new user "toto" has no homedir at all , dovecot will create /user/toto/mail at the very first successful connection ? Thanks a lot

[Dovecot] Issue with Dovecot v2.0 auto packages
by Stephan Bosch 25 Mar '11

25 Mar '11

Hi, Yesterday night I upgraded the automated packages built at Xi to the latest experimental Debian packages for v2.0. This unfortunately causes a problem upon upgrade. I've contacted the maintainer, so this issue should resolve itself soon. The issue manifests as follows: Setting up dovecot-imapd (2:2.0.11-0~auto+25) ... ucfr: Attempt from package dovecot-imapd to take /etc/dovecot/conf.d/20-imap.conf away from package dovecot-common ucfr: Aborting. dpkg: error processing dovecot-imapd (--configure): subprocess installed post-installation script returned error exit status 4 configured to not write apport reports The Debian maintainer split dovecot-common in various new packages and moved config files in the process. Use ucfr --purge --force dovoecot-imapd /etc/dovecot/conf.d/20-imap.conf ucfr --purge --force dovoecot-managesieved /etc/dovecot/conf.d/20-managesieve.conf ucfr --purge --force dovoecot-sieve /etc/dovecot/conf.d/90-sieve.conf to get rid of these errors as a workaround. I did this in combination with temporarily purging and removing Dovecot, but that is probably not necessary. Once you have upgraded, you will not encounter this problem again. And yes, if you are using Sieve, be sure to install the new dovecot-sieve and dovecot-managesieved packages. Regards, Stephan.

[Dovecot] Dotlock dovecot-uidlist errors / NFS / High Load
by list＠airstreamcomm.net 24 Mar '11

24 Mar '11

As of late our four node dovecot 1.2.13 cluster has been experiencing a massive number of these dotlock errors: Created dotlock file's timestamp is different than current time (1295480202 vs 1295479784): /mail/user/Maildir/dovecot-uidlist These dotlock errors correspond with very high load averages, and eventually we have to turn off all but one server to stop them from occurring. We first assumed this trend was related to the NFS storage, but we could not find a networking issue or NFS related problem to speak of. We run the mail storage on NFS which is hosted on a Centos 5.5 host, and mounted with the following options: udp,nodev,noexec,nosuid. Secondly we thought the issues were due to NTP as the time stamps vary so widely, so we rebuilt our NTP servers and found closer stratum 1 source clocks to synchronize to hoping it would alleviate the problem but the dotlock errors returned after about 12 hours. We have fcntl locking set in our configuration file, but it is our understanding from look at the source code that this file is locked with dotlock. Any help troubleshooting is appreciated.

[Dovecot] Problem with expire plugin and expunge
by Christoph Pleger 24 Mar '11

24 Mar '11

Hello, I am running dovecot 2.0.9 with expire plugin, using the sqlite backend. The following command is executed every day by cron: doveadm expunge -A mailbox Trash savedbefore 30d I started to use the expire plugin about one month ago. Since then, using "doveadm search -A mailbox Trash savedbefore <days>" with different values for <days>, I could see every day how the messages were getting older. Yesterday was the first time that the expression "savedbefore 30d" became true for the oldest messages in the Trash mailbox and these messages were actually deleted from Trash. But today, all messages that were not deleted yesterday are new to "doveadm search", that means that "doveadm search -A mailbox Trash savedbefore 0d" shows all messages from Trash, but "doveadm search -A mailbox Trash savedbefore 1d" shows no messages from Trash, though during the last month I moved messages to Trash every day.

[Dovecot] Configure Dovecot For IMAP Only?
by Carlos Mennens 23 Mar '11

23 Mar '11

I've install Dovecot 2.0.11-1 on my Linux server and all the guides and tutorials I've found on Google don't work since I'm running 2.x and it seems most guides were done with 1.x. I've opened up the configuration file /etc/dovecot/dovecot.conf & from what I can see, this is all I could come up with: protocols = imap listen = * base_dir = /var/run/dovecot login_greeting = Server ready. mail_location = maildir:~/mail I obviously want / need IMAP4 access ONLY and not POP3. I've got only 12 local Linux shell users and all authentication is done by I think PAM. My friend sent me his configuration file to see if it would work on Dovecot 2.x however I don't think it does: auth_mechanisms = plain login mail_location = maildir:~/mail passdb { driver = pam } protocols = imap service auth { unix_listener auth-client { group = postfix mode = 0660 user = postfix } user = root } ssl_cert = </etc/ssl/certs/cert.pem ssl_key = </etc/ssl/private/key.pem userdb { driver = passwd } #protocol imap { # imap_client_workarounds = delay-newmail tb-extra-mailbox-sep #} Can anyone please tell me what I need to add to get this very basic IMAP server up and running?

[Dovecot] Mail Sync
by Scott Hughes 23 Mar '11

23 Mar '11

I am trying to sync my mail on two different servers as testing for converting our business over to a server using dovecot. I am currently running dovecot version 2.0.11 While trying to sync the messages using Thunderbird and a program named imapsync, I run into an error stating that the dovecot server does not know how to handle messages with the FORWARD flag set. Is the FORWARD flag some type of non-standard flag or is there something I need to do in dovecot to allow for this flag? Thanks

[Dovecot] Bug: Creating mbox folders
by Kelly Stephens 23 Mar '11

23 Mar '11

Hey, I had trouble this morning creating a folder to contain sub-folders. I am using the mbox format. Turns out that the .imap directory in the new folder (directory) was not being created. Anytime I tried to view a sub-folder (using Thunderbird) dovecot would dump. Once I manually created the .imap directory, it works fine. dovecot --version -> 2.0.9 dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.35.11-83.fc14.i686 i686 Fedora release 14 (Laughlin) listen = * mbox_write_locks = fcntl passdb { driver = pam } protocols = imap ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } The maillog dump...

by Vincent Artzner 23 Mar '11

Hi there, I juste set up dovecot as local imap server last week, with maildir format. Things went fine with two "low volume" accounts, until I added another one. Then I see two different things with connected clients: 1/ Quite oftent well formed messages that appear... and disappear quite immediately. On the server, the messages concerned by 2/ seem to be there, I can open the files and it looks ok (header, content). The only error log I get is this: 2011-03-18 14:43:14 IMAP(info): Info: Disconnected: FETCH failed bytes=109363/174063195 2011-03-18 14:43:14 imap-login: Info: Login: user=<info>, method=PLAIN, rip=192.168.0.191, lip=192.168.0.10, TLS 2011-03-18 14:43:15 IMAP(info): Error: FETCH [] for mailbox Envois UID 11572 got too little data: 63454 vs 63455 2011-03-18 14:43:15 IMAP(info): Error: Maildir filename has wrong W value: /home/info/Maildir/.Envois/cur/1300450349.M120256P3108.Serveurlinux,S=460764,W=460768:2,S 2011-03-18 14:43:15 IMAP(info): Error: Corrupted index cache file /home/info/Maildir/.Envois/dovecot.index.cache: Broken virtual size for mail UID 11572 Please note the size: 63454 vs 63455: it's always like that: one byte difference.

I also reproduced it with opera mail client. I tried to rename/delete dovecot.index.cache files as I have read about it, but doesn't changed anything. The incoming mails are provided to dovecot by procmail, so I think dovecot is responsible for settings the S, W params in the filenames. No other process should alter the messages (i still have to fully check this). I am a bit lost (not a system administrator at all) and would be grateful for any advice. Vincent

[Dovecot] DoveCot 2.0.9: Problem with some Clients and separator (migrate from Cyrus)
by Denny Schierz 23 Mar '11

23 Mar '11

hi, we had to move from a old dieing Sparc very quickly our Cyrus IMAP Users to Dovecot. Most things works, but some Clients (like Evolution or Thunderbird) are strange. Our separator in Dovecot2 is "^", the mailboxes on the filesystem are something like "INBOX.subfolder1.subfolder2", but in TB and Evo I see INBOX^subfolder1^subfolder^ In Roundcube Webmail, I have just a normal tree, as I expected. I used cyrus2dovecot.pl for converting. On Evolution I deleted the IMAP Profile and recreated it, and that was working, but it isn't a workaround for TB So, how can I fix it? namespace { type = private separator = ^ prefix = inbox = yes hidden = no subscriptions = yes } cu denny

[Dovecot] Master user creds for proxy stored statically/locally?
by Edward Carraro 22 Mar '11

22 Mar '11

I have successfully set up the master user on the destination server (2.0.11) and tests have worked. now I'm working on the proxy Before I had the proxy just forward everything to the backend and had the destination server do the authentication. My authentication is done via LDAP but not really sure how to append the master user and password to the users credentials after authentication is done. id rather not have the master user/pass in each users ldap entry and returned after doing a lookup or add a destuser field for each user... basically i prefer not having to add any new attributes to LDAP Can the information be stored locally in a file on the proxy? do i just make the same master user file that I have on the backend? Thanks!

[Dovecot] Change password cheme
by Pascal Nobus 22 Mar '11

22 Mar '11

We want to update our password scheme from crypt to SHA256. Because usernames/passwords are in MySQL I thought this wouldn't be a problem. We have about 3000 users that need to be updated, so make a new password for them isn't possible. I was thinking of an automated script that would update the database after every login. So we did this: dovecot.conf: mail_executable = /usr/local/etc/updatepwd.sh updatepwd.sh: #!/bin/sh $USER $PASSWORD|/usr/local/etc/do_updatepwd.pl exec /usr/local/libexec/dovecot/imap "$@" (do_updatepwd.pl is a perl script that makes a sha256 from the second argument, and then update the mysql-query) However: the password is not in the ENVIROMENT anymore. I changed in dovecot the settings: auth_debug = yes auth_debug_passwords = yes Anyone a solution for this? Best regards, Pascal

[Dovecot] http://wiki2.dovecot.org/MailServerOverview contains poppycock
by William Blunn 22 Mar '11

22 Mar '11

Just having another look at http://wiki2.dovecot.org/MailServerOverview , it seems to have some statements in it which are misleading, and some which are really ... well ... wrong. Quote: "With the possible, optional, exception of the deliver MDA, Dovecot is not involved with reception, delivery, and storage of mail. That function is provided by a MTA such as postfix <http://www.postfix.org>. It is the MTA that determines where and how mail is stored - Dovecot must then be configured to retrieve the mail accordingly." (Entered by user "amfes".) This contains a significant proportion of poppycock. Dovecot includes extensive functionality for the storage (as in the action of storing) of e-mail as well as retrieval, in the shape of the LDA. Using Dovecot's LDA is /required/ in the case of Dovecot-specific mail storage formats (sdbox, mdbox). With mbox, use of the Dovecot LDA is advisable since it will guarantee a locking strategy which is compatible with Dovecot's mail retrieval functionality. And in any case, use of the Dovecot LDA has merit in that it should guarantee line-up between the mailstore configurations used for storage and retrieval. It is NOT the MTA that determines where and how mail is stored. It is the PERSON who configures the system who decides this, and codifies that configuration into whatever systems carry out local delivery and retrieval. It IS true that use of Dovecot's LDA is optional, but to say that it is a "possible exception" is misleading. People /should/ use the Dovecot LDA if they are using Dovecot IMAP/POP, and the /option/ is to use the MTA's local delivery system /if/ it is so indicated on a particular system. Quote: "Again, it bears repeating, Dovecot /is not responsible for mail delivery or storage/. Any questions on these issues involve your MTA and MDA. Get those working first." (Entered by user "DanielMiller".) Again, contains quite a lot of misleading nonsense. "Mail delivery" includes the hand-off of the message by the MTA to the LDA, and the storage of the message by the LDA. The LDA should probably be Dovecot, so really Dovecot /is/ partially responsible for mail delivery. "Storage" involves that placing of message into the message store. This should be done by Dovecot, so Dovecot is responsible for this. Bill

[Dovecot] dsync inbox conversion problem (mbox -> mdbox)

[Dovecot] Request - please uncomment !include_try /etc/dovecot/local.conf in example config
by Ng Oon-Ee 22 Mar '11

22 Mar '11

Hi, could I request that the example config in doc/dovecot/example-config/dovecot.conf be slightly altered to uncomment the last line? The point of include_try is that it only includes if such a file exists, and doesn't break anything if the file does not exist. My distro (Arch) has a policy not to apply non-essential patches, rather asking users to forward requests upstream, hence this email. It allows users to simply keep a local.conf with all their settings and not have to worry that it would not be used when the dovecot package gets upgraded (which mostly means /etc/dovecot/dovecot.conf gets replaced, depending on packaging standards). Thanks.

[Dovecot] dovecot proxy, imapproxy, perdition . . . or?
by Lorens Kockum 21 Mar '11

21 Mar '11

Hi, I have two load-balanced dovecot servers using a single NFS mount. The version is 1.2.11. I chose this so that if one server goes down the other will take up the load, and if my load is too much for one server I just have to add more identical servers. It works, but I wish to move to SAN storage because the NFS server is exhibiting irregular performance. (I spent a lot of time with tcpdump to check that it wasn't NFS locking problems). Performance is very important to me, not in the sense of many users but in the sense of quick response time, since the main use is as a webmail backend. That means that instead of load-balancing connections between servers I will have to partition users between servers (all on one to begin with) and direct users to the corresponding server. I expected to use perdition, but when reading up on that I found imapproxy, which could be interesting for performance reasons, and also that dovecot has an included proxy, and that its performance is better than perdition. However on http://wiki.dovecot.org/HowTo/ImapProxy the feature "IMAP/POP3 server with proxy feature" is noted as "This model is still a bit unfinished in current code." Is this still true? There's also a general note that "This page was written quite a long time ago and may not match reality anymore" . . .

[Dovecot] Virtual and system users with public mailboxes
by kshaw＠kendallshaw.com 21 Mar '11

21 Mar '11

Hi, I am running dovecot 1.2.9 and postfix, and I am trying to setup a public mailbox. My thought is that there would be one system user with a sieve script to deliver messages to the public mailbox. And, I would like to give virtual users access to the mailbox. On this list, I read how you can have both system and virtual users by using passdb and static userdbs. But, I don't understand how this can be combined with namespaces, where I specify the location. For all virtual users I had: mail_location = maildir:/var/somewhere/%u/maildir/ I think I need that for virtual users and: maildir:~/Maildir for the system users. namespace private { location = ? # how do I have the location be different for system and virtual users? } namespace public { location = ? # ditto (for the index)? } Kendall

[Dovecot] maildir location
by upen 21 Mar '11

21 Mar '11

Hello, I am trying to use dovecot (v. 2.0.11) and postfix (v. 2.7.3) together. The email server is an ldap client and user's home directories on NFS server are mounted using autofs. As I understand, Maildir performance is better than mbox type, so I'd like to use Maildir instead of mbox. However, when I checked conf.d/10-mail.conf file, there is mail_location = maildir:~/.maildir already configured in it which means user's email will reside in their home directories on the NFS server rather than being on Email server's local storage where plenty of space is available. I anticipate due to NFS there will again be a performance hit . Question : Can I change mail_location for maildir to be somewhere other than ~/.maildir. ( like /var/mail/%u/Maildir, where /var/mail is local storage). There are about 200 ldap users who will be using this email server through squirrel-mail or access them through email clients. By the way, I am confused about one setting in postfix : home_mailbox = .maildir/ in main.cf . Does this really play any role? If so, which parameter should be changed and to what and with what permissions to the new directory. Hope I was able to explain, if not please let me know for more details.. Thanks, U

[Dovecot] Can't disable chroot to 'empty' dir, but need to... how to do it?
by Tim Bessie 21 Mar '11

21 Mar '11

Hello all... I've installed dovecot on my ISP's shell server, and am using SSH tunnelling so that I can retrieve my mbox-format mail from procmail-processed mailboxes on that server (normally I just ssh there and read them locally with pine, but now that I have a phone with an IMAP client, I wanted to be able to read it more easily there). The problem I'm having is, although it's working, whenever dovecot starts up, or I try to log in, it attempts to chroot to /home/mydir/dovecot/var/run/dovecot/empty (where /home/mydir/dovecot is the path to my dovecot installation). I've turned off all chroot'ing in all the config files, but it still seems to want to chroot to that one directory. The message I see in the log is: Mar 19 02:09:43 master: Info: Dovecot v2.0.11 starting up (core dumps disabled) Mar 19 02:09:44 anvil: Fatal: chroot(/home/mydir/dovecot/var/run/dovecot/empty) failed: Operation not permitted Mar 19 02:09:44 master: Error: service(anvil): command startup failed, throttling This doesn't cause a problem accessing my mail, but it DOES seem to wait 60 seconds between attempts at chroot'ing, so logins to the server take that long (until the chroot fails). Is there any way I can disable this? Again, I've followed the instructions and set 'chroot=' (empty) for all services, but that hasn't helped. - Tim

[Dovecot] Sieve problems (not matching emails expected to match)
by Michael Welsh Duggan 21 Mar '11

I have a sieve file that reads like this: require "fileinto"; # Emacs if header :contains "List-Id" "emacs-devel.gnu.org" { fileinto "mail.emacs-devel"; } elsif header :contains "List-Id" "emacs-bidi.gnu.org" { fileinto "mail.emacs-bidi"; } ... Unfortunately the List-Id based lines don't appear to be working, although some other ones do. The attached test message does not get delivered to the mail.emacs-devel list. Why? -- Michael Welsh Duggan (md5i(a)md5i.com)
