[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.

[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>

[Dovecot] configure: error: unrecognized option: --docdir=/usr/share/doc/dovecot-2.0.11
by Bruce Cheng 07 Apr '11

07 Apr '11

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
