[Dovecot] Dovecot 1.2.5 segfaults.

Hi, I just updated to dovecot 1.2.5 on centos5. 1.2.4 did not show this problem. I am going to roll back for the time being but I am willing to do whatever I need to to fix this. This is an x86_64 system. filesystem is ext3. I am now seeing the following in the logs: Sep 22 17:31:06 vfoggy kernel: imap[18644]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007fff83e31c88 error 14 Sep 22 17:31:06 vfoggy kernel: imap[18645]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007fffe70ee878 error 14 Sep 22 17:31:07 vfoggy kernel: imap[18682]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007fff3f95ac18 error 14 Sep 22 17:31:52 vfoggy kernel: deliver[18748]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007ffffd6d3aa8 error 14 Sep 22 17:32:07 vfoggy kernel: deliver[18782]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007fff89c022e8 error 14 Sep 22 17:32:07 vfoggy kernel: deliver[18784]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007fff40a23718 error 14 Sep 22 17:32:07 vfoggy kernel: deliver[18786]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007ffff66eedb8 error 14 Sep 22 17:32:26 vfoggy kernel: deliver[18896]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007ffffe99f0c8 error 14 Sep 22 17:33:07 vfoggy kernel: deliver[18994]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007fffb2b5ddc8 error 14 Sep 22 17:34:30 vfoggy kernel: deliver[19022]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007fffdfaac988 error 14 Sep 22 17:35:25 vfoggy kernel: deliver[19050]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007fff7865f198 error 14 Sep 22 17:35:26 vfoggy kernel: deliver[19052]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007fffb61b0f68 error 14 Sep 22 17:36:42 vfoggy kernel: imap[19072]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007fffc7bd1118 error 14 Sep 22 17:36:42 vfoggy kernel: imap[19073]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007fff9ceb4f48 error 14 Sep 22 17:36:42 vfoggy kernel: imap[19074]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007fff7d762c78 error 14 Sep 22 17:36:42 vfoggy kernel: imap[19075]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007fffefebafa8 error 14 Sep 22 17:36:42 vfoggy kernel: imap[19076]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007fffe568c798 error 14 Sep 22 17:36:42 vfoggy kernel: imap[19077]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007fffc2f2d2b8 error 14 Sep 22 17:36:42 vfoggy kernel: imap[19078]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007fff6bb39a68 error 14 Sep 22 17:36:42 vfoggy kernel: imap[19079]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007fff5c3ae628 error 14 Sep 22 17:36:42 vfoggy kernel: imap[19081]: segfault at 0000000000000000 rip 0000000000000000 rsp 00007fffb75b4958 error 14 As per http://dovecot.org/bugreport.html Dovecot -n follows: (vfoggy pts1) #

[Dovecot] Solr Plugin make only INBOX able to search
by rui.carneiro＠portugalmail.net 23 Sep '09

23 Sep '09

Hi all, I have downloaded and installed dovecot 1.2.4 with Solr plugin. After that, when I try to do some searches the results are weird. All messages that aren't on INBOX folder are ignored. For example, if I have a folder named "Test Folder", when I try to do ". search text <string>" the result is always empty. I tried TEXT, SUBJECT and BODY arguments and none of them returned any email. Any idea of the problem's source? Regards, Rui Carneiro

[Dovecot] SharedMailboxes in a distributed environment
by Christian Rohmann 23 Sep '09

23 Sep '09

Hello folks, I'd like your thoughts on the following problem: If one is using v1.2+ IMAP ACLs to allow users to share their mailbox and uses SQL as dictionary backend, every dovecot server would know which ACLs to enforce. But as the wiki states here "http://wiki.dovecot.org/SharedMailboxes/Shared" dovecot needs access to the other mailbox. Does that automatically mean that one dovecot machine needs to have filesystem access to the all mailboxes that are to be shared? Is there no way to share mailboxes (folders) between different servers? (apart from using NFS i.e.) -- Christian Rohmann Content Delivery Server u.

[Dovecot] shared/public mailbox doesn't exist
by Eric Shubert 22 Sep '09

22 Sep '09

I have 3 servers running dovecot 1.0.10. 2 of them are configured with a shared/public namespace, but I'm having trouble getting it to work on the third, even with 2 working examples to go by. There's something I'm missing, and I'm hoping that someone here can see/tell what it is. I've created the maildir for sharing: # cd /home/vpopmail/domains/mydomain.com # maildirmake shared # chown -R vpopmail:vchkpw shared Then added the configuration to dovecot.conf: # shared namespace namespace shared { separator = . prefix = shared. location = maildir:/home/vpopmail/domains/mydomain.com/shared } Restarted dovecot: # service dovecot restart When I try to subscribe to the shared namespace though with Outlook, I get: "Failed to subscribe the folder. Server responded: 'Mailbox doesn't exist: shared'." When I try to subscribe with Squirrelmail I get: "ERROR: Could not complete request. Query: SUBSCRIBE "shared" Reason Given: [TRYCREATE] Mailbox doesn't exist: shared" I've tried various combinations of permissions to no avail. Suggestions welcome. I'm at my wits end. -- -Eric 'shubes'

[Dovecot] Dovecot versions and index compatibility
by Steven F Siirila 22 Sep '09

22 Sep '09

I realize these are older versions, but I'd like to know specifically whether dovecot 1.1.6 and dovecot 1.1.8 are compatible index-wise. In particular, if we downgraded from 1.1.8 to 1.1.6 would there be any issues with doing so? I realize there are later versions, but we've tested both of the above extensively, but recently loaded up a server with 1.1.8 and found that the 'imap' process core dumps frequently, so before we pursue later versions we thought it would be best to downgrade to 1.1.6. -- Steven F.

[Dovecot] Managesieve displays folder name (dovecot/sieve)
by Seba 21 Sep '09

21 Sep '09

Hi, I'm using Dovecot 1.2.4 with ManageSieve 0.11.9 and Sieve. All works fine but users can subscribe to the folder "dovecot/sieve" which is also displayed in the folders list. protocols = imap managesieve protocol managesieve { listen = ip_address:2000 managesieve_logout_format = bytes ( in=%i : out=%o ) } plugin { sieve=~/Maildir/.dovecot.sieve sieve_dir=/home/vmail/%d/%n/Maildir } In the maildir of the user I see this folders and files: .Drafts/ .Sent cur/ new/ temp/ sieve/ @.dovecot.sieve ingo.sieve The file "ingo.sieve" comes from Horde Ingo because users manage their scripts with ingo.The symlink "dovecot.sieve" is correct and point to ingo.sieve. When users browse their available IMAP folders they'll see a folder "dovecot/sieve". Can this be turned off or restricted with acl's? Without an symlink all folders are displayed normally without the "dovecot sieve" folder. Thanks.

[Dovecot] Maildir quota reporting
by David Kmoch 21 Sep '09

21 Sep '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm little confused with the way dovecot (1.2.4) is reporting quota. with this config protocols: imaps ssl: required ssl_ca_file: /root/cert/CA_Bundle_Trans.crt ssl_cert_file: /root/cert/mails.crt ssl_key_file: /root/cert/mails-key.pem.rsa disable_plaintext_auth: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login mail_location: maildir:%h/Maildir mail_debug: yes mail_plugins: quota imap_quota lda: postmaster_address: postmaster(a)example.com mail_plugins: quota cmusieve mail_plugin_dir: /usr/lib/dovecot/lda auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd plugin: quota: maildir:User quota quota_rule: ?:storage=20G sieve: ~/.dovecot.sieve everything works fine. TB says, there 20G quota. Command echo "1 GETQUOTAROOT INBOX" | USER=foo dovecot --exec-mail imap reports * QUOTAROOT "INBOX" "User quota" * QUOTA "User quota" (STORAGE 0 20971520) 1 OK Getquotaroot completed. Now I change the first line in foo's maildirsize file to "0S" to allow unlimited quota. Then I boost it's size to force recalculation (just to be sure) dd if=/dev/zero bs=1k count=6 >> ~foo/Maildir/maildirsize - From now, TB still reports 20GB quota for user foo, the above "echo" command still reports 20971520, but(!), quota is actually unlimited for user foo. OK, now I stop dovecot, delete maildirsize, change line in dovecot.conf quota_rule = ?:storage=0 and start dovecot again. The same result - TB still reports 20GB quota for user foo, the above "echo" command still reports 20971520, but(!), quota is actually unlimited for anyone. When I set some limit in ~foo/Maildir/maildirsize now, same values 20971520) are reported, although the limit works! Looks like LDA (deliver) works fine, but imap_quota plugin is doing something weird. Finally, the question ;-) Where does that value (20971520) come from? Is it a feature or a bug? - -- David Kmoch -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkqfhQoACgkQsUUM+N2AWobj7ACgh3yCU9LVfe1Pp2lO0nBG9iKf zbgAn15UvkVM0AeCxaUlDeYgFu++8TOn =CAoG -----END PGP SIGNATURE-----

[Dovecot] plugin development guide for non-FS backing store
by Chang Song 21 Sep '09

21 Sep '09

Hi, folks. I was wondering if anyone has some sort of guide or reference on plugin development. We are trying to develop a non-filesystem backing store. So basically we do not store mailboxes for users in local filesystem. We do RPC call to fetch from fileservers. Thank you in advance. Chang
