Dovecot 2.1.9 shared folder deletion causes fault
by JT 19 Jun '15

19 Jun '15

Hey all, I'm getting a fault in dovecot (see below) using shared folders. I have a mailbox that receives new mail (Account X/INBOX). Another account (Account A) has access to the other account (Account X/INBOX) with ACL below. The ACL directory (.DEFAULT) contains: user=AccountA lrwst I removed a test email from Account A/INBOX, which is supposed to remove the email from Account X/INBOX. A fault occurs whenever my client (Thunderbird) attempts to connect and complete the deletion. Other actions complete successfully. It only appears to happen when using Thunderbird. Mac Mail does not cause the fault. I'm not getting a core dump so all I have is what the log outputs. I can reproduce this regularly so let me know if you need any additional information. Thanks, JT === Version: 2.1.9 (Ubuntu Trustydeb package) OS: Ubuntu trusty 14.04 2015-06-18T19:17:50.518505+00:00 mail-103 dovecot: imap(XXX): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x5e271) [0x7eff3f6d1271] -> /usr/lib/dovecot/libdovecot.so.0(+0x5e34e) [0x7eff3f6d134e] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7eff3f68ca9e] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0xa7cbc) [0x7eff3f9e2cbc] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_copy+0x6c) [0x7eff3f9ac8ec] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_move+0x15) [0x7eff3f9ac985] -> dovecot/imap(+0xded5) [0x7eff3fe78ed5] -> dovecot/imap(command_exec+0x3c) [0x7eff3fe836dc] -> dovecot/imap(+0x176cf) [0x7eff3fe826cf] -> dovecot/imap(+0x17785) [0x7eff3fe82785] -> dovecot/imap(client_handle_input+0x125) [0x7eff3fe82aa5] -> dovecot/imap(client_input+0x75) [0x7eff3fe82e35] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x27) [0x7eff3f6e1247] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xd7) [0x7eff3f6e1fd7] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7eff3f6e0de8] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7eff3f691c93] -> dovecot/imap(main+0x2c4) [0x7eff3fe772f4] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf5) [0x7eff3f2cfec5] -> dovecot/imap(+0xc460) [0x7eff3fe77460] 2015-06-18T19:17:50.736901+00:00 mail-103 dovecot: imap(XXX): Fatal: master: service(imap): child 4461 killed with signal 6 (core dumped) 2015-06-18T19:17:51.662157+00:00 mail-103 dovecot: imap(XXX): Panic: file mail-index.c: line 380 (mail_index_keywords_unref): assertion failed: (keywords->refcount > 0) 2015-06-18T19:17:51.662969+00:00 mail-103 dovecot: imap(XXX): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x5e271) [0x7f3fa05bb271] -> /usr/lib/dovecot/libdovecot.so.0(+0x5e34e) [0x7f3fa05bb34e] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f3fa0576a9e] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0xa7cbc) [0x7f3fa08cccbc] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_copy+0x6c) [0x7f3fa08968ec] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_move+0x15) [0x7f3fa0896985] -> dovecot/imap(+0xded5) [0x7f3fa0d62ed5] -> dovecot/imap(command_exec+0x3c) [0x7f3fa0d6d6dc] -> dovecot/imap(+0x176cf) [0x7f3fa0d6c6cf] -> dovecot/imap(+0x17785) [0x7f3fa0d6c785] -> dovecot/imap(client_handle_input+0x125) [0x7f3fa0d6caa5] -> dovecot/imap(client_input+0x75) [0x7f3fa0d6ce35] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x27) [0x7f3fa05cb247] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xd7) [0x7f3fa05cbfd7] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x38) [0x7f3fa05cade8] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f3fa057bc93] -> dovecot/imap(main+0x2c4) [0x7f3fa0d612f4] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf5) [0x7f3fa01b9ec5] -> dovecot/imap(+0xc460) [0x7f3fa0d61460] 2015-06-18T19:17:51.857451+00:00 mail-103 dovecot: imap(XXX): Fatal: master: service(imap): child 4464 killed with signal 6 (core dumped) protocol imap { imap_client_workarounds = tb-extra-mailbox-sep imap_idle_notify_interval = 1 mins mail_max_userip_connections = 10 mail_plugins = acl quota acl imap_acl quota imap_quota } plugin { acl = vfile:/etc/dovecot/acl acl_defaults_from_inbox = yes acl_shared_dict = proxy::acl ... } namespace { hidden = no inbox = yes list = yes location = prefix = separator = / subscriptions = yes type = private } namespace { hidden = no list = children location = maildir:/var/mail/public/Maildir:INDEX=/var/mail/%d/%n/Maildir/public prefix = public/ separator = / subscriptions = yes type = public } namespace { list = yes location = maildir:%%h/Maildir:CONTROL=~/Maildir/control/%%u:INDEX=~/Maildir/shared/%%u.indx:INDEXPVT=~/Maildir/shared/%%u.pvt prefix = shared/%%u/ separator = / subscriptions = no type = shared }

maildir, how to always add size tags to filename (,S=).
by Sergei Franco 19 Jun '15

19 Jun '15

Hi There, I have thoroughly read through documentation and wiki and I simply cannot find how to force dovecot to always add the size tag to the filename when using maildir format. We are using dovecot 2.2.9 (whatever comes from ubuntu 14.04 LTS). We are using dovecot in conjunction with exim with maidirsize file enabled and maildir quotas. For example exim has following configuration: maildir_tag = ,S=$message_size Which adds the size to the filename of the message. This has enormous (orders of magnitude) performance benefit as to calculate quota one does not need to stat every single file (only getents for each directory). I have wrote a script that adds the size tag retrospectively to files it didn't had it, and rebuild the dovecot index/cache if changes where made. This worked fine. Behaviour of dovecot is very peculiar: it generally adds the ,S= tag (along with ,W= tag) but occasionally it does not (I wander if it depends on the IMAP client). Is there anyway to force dovecot to add size tag to the files (like with exim example above)? Thank you very much. Sergei.

Best practices for mailbox network file storage?
by Andy Csillag 18 Jun '15

18 Jun '15

Is there a current best practice for a shared filesystem backend for mailboxes (in my case, all virtual accounts)? NFS 3/4, GFS2, GlusterFS, other? In the case of the latter ones, is the use of Director necessary? Any specific anti-recommendations? Also, if it matters, I *think* I want to use BackBlaze racks for storage. Also, I've seen recommendations for the filesystem underneath like XFS or ext4 or whatever. Is there a best practice? Thanks, Drew

Most of my users are virtual. Do I need defined namespaces or is the default undefined one OK?

LMTP with Postfix Problem
by Steve Matzura 18 Jun '15

18 Jun '15

Here's a maillog entry that's one of many I receive when I try sending a test message to my system. The recipient is a virtual user in /etc/virtual. The way I'm expecting it to work is that my message from me to this Postfix virtual user will be sent back to me. Every time the message delivery is attempted, Dovecot says the LMTP directory doesn't exist. I thought it was created automatically as messages arrive.

Pigeonhole vacation from alias address
by Dino Blazeka 18 Jun '15

18 Jun '15

Hi everyone. I've set up my instance not to check recipient address with sieve_vacation_dont_check_recipient=yes to enable users to set up their vacation script without listing addresses (there are to many). Only problem remaining is that when they receive an e-mail sent to their alias, the vacation response comes from their original mail address. Is there a setting or workaround that would enable vacation extension to send response with from field set to whichever address the original message was addressed to. Thank you in advance, Dino P. S. This is my first message to the list so I apologize in advance if I have broken any rules. It was not done intentionally

privilege of process executed by extprograms plugin
by Takahiro Yakoh 18 Jun '15

18 Jun '15

Hi, I'm just a beginner of extprograms plugin of sieve. When I execute a process via execute or pipe command, the process start with "root" privilege. Why? I believe the process must be executed with recipient privilege. Give me some checkpoints, or hints, please. My setup is as follows: Ubuntu 14.04.2 LTS 64bit + dovecot-core, dovecot-sieve plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_execute_bin_dir = /some/where sieve_extensions = +vnd.dovecot.execute +vnd.dovecot.pipe sieve_pipe_bin_dir = /some/where sieve_plugins = sieve_extprograms } protocol lmtp { mail_plugins = " sieve" postmaster_address = postmaster(a)some.where } Yakoh

bug in indexer/indexer-worker
by Infoomatic 18 Jun '15

18 Jun '15

Hi, I have already mentioned this in http://www.dovecot.org/pipermail/dovecot/2014-November/098592.html I could reproduce the errors above in a self-compiled v2.2.18 and the prebuilt packages from xi.rename-it.nl (in addition to version 2.2.15 mentioned in the link) The problem occurs when enabling fts_tika in the plugins (tried tika 1.6, 1.7 and 1.8). I tried to move a folder of my mailbox with about 2000 mails to my server (no users, modern hardware). At some point I get an error and from this time on dovecot keeps repeating the last lines with every mail that comes in ... see [1] I then get kernel syslog messages like in [2]. when I try to index all users (had another testuser) mailboxes with "doveadm index" I get the errors of [3]. The mailfolder does contain mails with attachments of all sorts, videos, office documents etc. When disabling fts_tika it works. dovecot -n output is [4] Could someone of the devs please have a look? best regards, infoomatic [1] Then comes the panic which produces loads of errormessages below the "Raw backtrace" part: Jun 16 10:11:08 testhost dovecot: indexer-worker(user1): Warning: I/O leak:
