[Dovecot] Command died with signal 6
by Gourav Joshi 12 Jul '10

12 Jul '10

Hi, We have dovecot 1.1.20 running on Fedora 7 with mail and indexes on NFS. On our delivery server we are getting "status=bounced (Command died with signal 6: "/usr/local/libexec/dovecot/deliver")" We are fetching these mails from another server which has Centos 5.2 installed. We have mail_nfs*=yes and mmap_disable=yes settings in dovecot.conf. Please let me know why the above error coming in dovecot logs? Regards, Gourav Joshi

[Dovecot] maildir / deliver question
by Martin Waschbuesch 12 Jul '10

12 Jul '10

Hi all, I have the following situation: On a qmail toaster I am running (with dovecot 1.2.12 as the IMAP server), spam mail gets automatically put into a 'this might be spam' folder (per user). Now, every user has the opportunity to move that mail into either a 'learn as spam' or a 'this was ham' folder and the mail items will be treated accordingly. As a cronjob, I run a script that loops through all the users' folders and either learns as spam and deletes or learns as ham and moves back to the user's inbox. My questions now are these: 1.) Is there any danger regarding maildir consistency in directly moving mail items about? 2.) Could I somehow use deliver to move the mails? I think I can recall that other LDAs (maildrop?) allow for that? This would of course be preferred as the maildir cache would also still be optimized after the operation. If anyone has any suggestions, I'd really appreciate this. Thanks a lot for your help and this great tool!

[Dovecot] Doveadmn Quota
by Steven King 12 Jul '10

12 Jul '10

Hey Everyone, I am running the new Dovecot 2.0 RC2. When I try to run 'doveadm quota recalc -A' I just get the usage info for doveadm. Running 'doveadm help quota' gives me the man page for the quota command, and I follow the man page examples as is. Is this feature not implemented yet? Or am I doing something wrong? I know quota is a "plugin" for the doveadm program, but there is no documentation on how to get this to load of if it needs to be loaded at all.

[Dovecot] SSL / TLS Problem
by Leander S. 11 Jul '10

11 Jul '10

P.S. Postfix TLS/SSL works still fine ... I don't understand why dovecot doesn't want to work with the new thunderbird version ... Hi, since I upgraded to the new Thunderbird version 3.1 I can't establish a TLS/SSL connection anymore. But before the update Thunerbird was able to establish an encrypted session ... Maillog shows me the following now: server dovecot: imap-login: Disconnected (no auth attempts): rip=84.157.133.248, lip=192.168.1.100, TLS handshaking: SSL_accept() failed: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca Why is the CA unknowen - all of a sudden - ?! Thanks

[Dovecot] Dovecot 2.0 RC1 and OpenBSD 4.7
by D F 10 Jul '10

10 Jul '10

Hello all, I'm currently doing some tests with Dovecot 2.0 RC1 and OpenBSD4.7 (socppc or i386 architectures) and I can't compile it : I "./configure" with default options and then "make" : $ make [...] Making all in doc Making all in man make: don't know how to make doveadm.1. Stop in /home/mail/dovecot-2.0.rc1/doc/man. *** Error code 1 Stop in /home/mail/dovecot-2.0.rc1/doc (line 386 of Makefile). *** Error code 1 Stop in /home/mail/dovecot-2.0.rc1 (line 505 of Makefile). *** Error code 1 Stop in /home/mail/dovecot-2.0.rc1 (line 328 of Makefile). $ Is there any thing I can try ? Thank you in advance, Denis

[Dovecot] --with-PACKAGE is not recognized (dovecot 2.0.rc2)
by Sven Kirmess 10 Jul '10

10 Jul '10

The build process/configure script does not recognize the --with-PACKAGE option. Unfortunately I have no experience with autoconfigure/automake but maybe someone on the list knows how to fix this? I assume it should be an easy fix as most software recognizes the --with-PACKAGE flag. :) This is how I build dovecot: LDFLAGS=-L/opt/openssl \ CPPFLAGS=-I/opt/openssl \ ./configure --prefix=/opt/dovecot-2.0.rc2 --sysconfdir=/etc/opt/dovecot --localstatedir=/var/opt/dovecot --datarootdir=/opt/dovecot-2.0.rc2 --docdir=/opt/dovecot-2.0.rc2/doc --with-rundir=/var/opt/dovecot/run --with-statedir=/var/opt/dovecot/state --with-PACKAGE=no --with-ssl=openssl --with-ssldir=/etc/opt/dovecot; \ /usr/sfw/bin/gmake And I get the following warning: configure: WARNING: unrecognized options: --with-PACKAGE Same for --without-PACKAGE: configure: WARNING: unrecognized options: --without-PACKAGE This results in dovecot installing in the following wrong directories: /etc/opt/dovecot/dovecot /opt/dovecot-2.0.rc2/include/dovecot /opt/dovecot-2.0.rc2/lib/dovecot /opt/dovecot-2.0.rc2/libexec/dovecot The argument --with-PACKAGE=no should be usable to disable these interemiate dovecot directories which are only useful if you install all software in /usr/local.

[Dovecot] dsync duplicates messages/crashed if a 'large' number of messages has been deleted

Hi, I try to mirror two dovecots with: dsync -v -f -u login mirror ssh -o IdentityFile=/etc/dovecot/dsync.d/id_rsa root@shrike dsync -u login This usually works, but if I delete a certain number of emails, I get this messages: dsync-local(mailverwalter): Info: Posteingang: Ignored 178 modseq changes dsync-local(mailverwalter): Info: Posteingang: Couldn't keep all uids dsync-local(mailverwalter): Warning: Mailbox changes caused a desync. You may want to run dsync again. after a second try I get: dsync-local(mailverwalter): Panic: dsync brain state=10 dsync-local(mailverwalter): Error: Raw backtrace: /usr/local/lib/dovecot/libdovecot.so.0 [0xf7e44541] -> /usr/local/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x4e) [0xf7e4466e] -> /usr/local/lib/dovecot /libdovecot.so.0(i_error+0) [0xf7e44878] -> dsync [0x804f4d6] -> dsync [0x80537c7] -> dsync [0x8053a82] - > /usr/local/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xf5) [0xf7e50bc5] -> /usr/local/lib/dovecot /libdovecot.so.0(io_loop_run+0x30) [0xf7e4fc10] -> /usr/local/lib/dovecot/libdovecot.so.0(master_service_ run+0x2a) [0xf7e3d29a] -> dsync(main+0x732) [0x804db32] -> /lib/libc.so.6(__libc_start_main+0xe5) [0xf7cd 1455] -> dsync [0x804d0c1] Regards, Matthias

[Dovecot] Mercurial dovecot-2.0 branch change
by Timo Sirainen 10 Jul '10

10 Jul '10

I got tired of seeing the HEAD branch name in hg.dovecot.org (caused by the initial import from CVS), so I finally switched to "default" branch name where it doesn't show it. But apparently now everyone using dovecot-2.0 hg needs to switch to the default branch. You should see something like: ~/cvs/dovecot-2.0% hg pull -u .. not updating, since new heads added (run 'hg heads' to see heads, 'hg merge' to merge) Now give a command: hg up -C default Hopefully there won't be other problems with the change.

[Dovecot] TLS handshaking error: unknown ca
by Ben Jordan 10 Jul '10

10 Jul '10

I'm running Ubuntu 10.04, recently upgraded. My dovecot version is 1.2.9. My SSL/TLS authentication with dovecot from non-local IP's has stopped working, and I can no longer access my mail securely. I have changed all entries to refer to my server as "host". I am the only user, and am OK with the a self-signed cert. When I try to connect using Thunderbird, the certificate window says "unable to obtain identification status for the given site".
