[Dovecot] Solution: NFS & Dovecot!
by Apps Lists 05 May '06

05 May '06

Hi folks! It looks like Timo nailed down the NFS issues we've been seeing here in last night's CVS build. Anyone running Dovecot in a high-usage environment should check this out. Here are some relevant ChangeLog updates that seem to address the problem: 2006-05-02 11:11 Timo Sirainen <timo.sirainen(a)movial.fi> * src/lib-storage/index/maildir/: maildir-save.c, maildir-storage.h, maildir-sync.c, maildir-uidlist.c, maildir-uidlist.h: Adding mail to index while saving it had a race condition. Fixing it required a bit larger changes. Switched uidlist/index locking order so that uidlist is now locked first. 2006-05-02 11:04 Timo Sirainen <timo.sirainen(a)movial.fi> * src/lib-index/: mail-index-private.h, mail-index-sync-update.c, mail-index.c: mmap_disable: When syncing in-memory index from transaction log, we didn't skip external transactions which were already been in our in-memory mapping, causing "Append with UID n, but next_uid = m" errors. The build is available here: http://dovecot.org/nightly/dovecot-20060503.tar.gz Thus far, I've seen no complaints of corrupted indexes or core dumps. This is absolutely fantastic. As always... hats off to Timo. Great work! Steve

by Gavin Henry 05 May '06

Dear all, Getting lots of these errors in our maillog with the INDEX changed: dovecot: IMAP(ghenry): fchown() failed with file /home/ghenry/Maildir/index/.INBOX/dovecot.index.tmp: Operation not permitted For .log and .cache as well. We have: location = maildir:/home/%u/Maildir:CONTROL=%h/Maildir/control:INDEX=%h/Maildir/index I looked in safe-mkdir.c and saw: fchown() failed for (line 42) to change the owner first, so don't know why we are getting this error?

[Dovecot] dovecot LDA and pop3 session lock question
by Ken A 05 May '06

05 May '06

If pop3_lock_session = yes, how does Dovecot LDA handle the situation when the pop3 mbox is locked? Does it requeue mail for later delivery immediately (EX_TEMPFAIL), or wait until mbox_lock_timeout? Thanks, Ken A. Pacific.Net

[Dovecot] Problems with Dovecot 1.0 beta7 rpm form atrpm for RHEL4
by Oliver Schulze L. 05 May '06

05 May '06

Hi, I just want to install dovecot 1.0 beta7 from atrpm and noted that it depends on a non official dependency. If you have RHEL4 (Centos) 4.3 fully updated and you try to install: http://dl.atrpms.net/all/dovecot-1.0-0_10.99.beta7.el4.at.i386.rpm You get this error: # rpm -ivh dovecot-1.0-0_10.99.beta7.el4.at.i386.rpm error: Failed dependencies: openssl >= 0.9.7f-4 is needed by dovecot-1.0-0_10.99.beta7.el4.at.i386 The lates official openssl version for RHEL 4.3 is: # rpm -q openssl openssl-0.9.7a-43.8 I think I can solve this problem by compiling the src.rpm, but I get this error: # rpmbuild --rebuild --target=i686 --clean dovecot-1.0-0_10.99.beta7.el4.at.src.rpm Installing /opt/shares/tmp/dovecot-1.0-0_10.99.beta7.el4.at.src.rpm Building target platforms: i686 Building for target i686 error: line 4: Tag takes single token only: Release: 0_%atrelease 10.99.beta7 How can I compile the .src.rpm from atrpm? It seems that there is an error in the spec file: This line: Release: 0_%atrelease 10.99.beta7 should it looks like this: Release: 0_%{atrelease}10.99.beta7 Many thanks Oliver -- Oliver Schulze L. <oliver(a)samera.com.py>

[Dovecot] running only the dovecot-auth service
by Udo Rader 05 May '06

05 May '06

Hi, we are just testing postfix 2.3 in combination with its new dovecot SASL plugin. Now what we would like to have was dovecot SASL without acutally running dovecot ... The reason for this is because we have the "real" dovecot running on a different server than the postfix instance and it would be nice if it would not be necessary running an "full" dovecot on that server for only SASL support. So is it possible to start only the "dovecot-auth" part of dovecot? Another idea that I had was to export the created auth socket via nfs. Somewhere, sometimes I think to have read that it was possible to use unix domain sockets over nfs mounted shares, but I am not sure about this (and have failed so far).

[Dovecot] Bug in new mail-index-transaction.c
by Bill Boebel 04 May '06

04 May '06

These changes apparently broke something: > 2006-04-24 09:17 Timo Sirainen <timo.sirainen(a)movial.fi> > > * src/lib-index/mail-index-transaction.c: Fixed crash while > updating keywords (broken by recent changes). > > 2006-04-20 14:10 Timo Sirainen <tss(a)iki.fi> > > * src/lib-index/mail-index-transaction.c: If we sorted appended > messages, we weren't sorting extensions and keywords so they were > mapped to wrong messages (dbox-only problem, keywords not yet > fixed by this change). What I am seeing is when there are messages that have keywords set, Dovecot occasionally hangs while building the index and/or uidlist. It leaves a lock file "dovecot-uidlist.lock" around and the IMAP process reading that folder never completes successfully. To fix it, I have have to rename the message files to remove the keyword. For example: $ mv 1146246349.P365Q2.mail1b.r1.iad.emailsrvr.com:2,Sa 1146246349.P365Q2.mail1b.r1.iad.emailsrvr.com:2,S I reverted back to the copy of src/lib-index/mail-index-transaction.c from the 4/14/2006 CVS snapshot, and this problem completely went away. And mailboxes that were encountering the .lock problem suddenly worked again. If there is any additional information that you need in order to troubleshoot this bug, please let me know and I'll be happy to send it. Bill
