[Dovecot] Fatal: chdir( ) failed: Permission denied
by Vallo Kallaste 05 Feb '10

Hi Dovecot fails to chdir() into users home directory giving the following error: Oct 9 16:43:49 jura dovecot: dovecot: Fatal: chdir(/a/home/mina) failed: Permission denied (euid=1118 0(mina) egid=11332(devel) missing +x perm: /a/home) Oct 9 16:43:49 jura dovecot: dovecot: child 14441 (imap) returned error 89 (Fatal failure) The reason seems to be that user primary group is "devel" and directory /a/home has ACL which gives execute permission only to the users in "domain users" group. Now the catch is that the user _is_ member of "domain users" group and is happily accessing his home directory over CIFS(Samba) for long time. Also, the user has no problem entering his home directory when using shell access. It just seems like the user lost membership of a bunch of supplementary groups. The group membership info is coming from M$ PDC via winbind and NSS. We have few users and can change the users primary group and/or relax the /a/home directory ACL, but overall this is not right. Shall I shut up or can we hope for a fix or at least explanation? Thanks jura:/a # ls -la drwxrws--T+ 3 root domain admins 18 Oct 8 15:10 home jura:/a # getfacl home/ # file: home # owner: root # group: domain\040admins user::rwx group::rwx group:domain\040users:--x mask::rwx other::--- -- Vallo

[Dovecot] Two different issues with dovecot 1.1.13
by Stuart Rowan 20 Jan '10

20 Jan '10

Hi Timo, I'm using Debian backports.org dovecot-imapd, 1:1.1.13-2~bpo50+1. I've got two different issues, a reoccurring, seemingly harmless one about "Corrupted index cache file" (boring.txt) and one that went bonkers over the least few days (bt.txt) causing much spamming of the logs. I've made bt.txt stop happening by just rm'ing dovecot.index* : find Maildir/ -type f -name 'dovecot.index*' -print0 | xargs -0r rm ... which I realise may not be the most helpful thing to have done from your point of view. Anyway I just wanted to let you know about both of these. If one or both are already known about or already fixed by a later version of Dovecot, great and sorry for the noise! If not, and you want any more information etc., let me know. Many thanks, Stu. dovecot: 2009-07-28 10:23:16 Error: IMAP(strr): Corrupted index cache file /home/local/strr/Maildir/dovecot.index.cache: record continues outside its allocated size dovecot: 2009-07-28 10:23:56 Error: IMAP(strr): Corrupted index cache file /home/local/strr/Maildir/dovecot.index.cache: record continues outside its allocated size dovecot: 2009-07-28 08:05:54 Panic: IMAP(strr): file index-mail-headers.c: line 77 (index_mail_parse_header_finish): assertion failed: ((match[match_idx] & HEADER_MAT CH_FLAG_FOUND) == 0) dovecot: 2009-07-28 08:05:54 Error: IMAP(strr): Raw backtrace: imap [0x48dbf2] -> imap [0x48dc73] -> imap [0x48d346] -> imap(index_mail_parse_header+0x617) [0x4545f7] -> imap [0x483284] -> imap [0x483478] -> imap(i_stream_read+0x2c) [0x491d7c] -> imap(i_stream_read_data+0x46) [0x491f16] -> imap(message_get_body_size+0x108) [0x4885 a8] -> imap [0x4226c3] -> imap(imap_fetch+0x162) [0x420852] -> imap(cmd_fetch+0x23c) [0x41a27c] -> imap [0x41e46c] -> imap [0x41e51d] -> imap [0x41eb25] -> imap(clien t_input+0x63) [0x41efd3] -> imap(io_loop_handler_run+0xcb) [0x49515b] -> imap(io_loop_run+0x18) [0x4945c8] -> imap(main+0x3da) [0x426bea] -> /lib/libc.so.6(__libc_sta rt_main+0xe6) [0x7f0e851941a6] -> imap [0x418859] dovecot: 2009-07-28 08:05:54 Error: child 20007 (imap) killed with signal 6 (core dumps disabled) dovecot: 2009-07-28 08:05:56 Panic: IMAP(strr): file index-mail-headers.c: line 77 (index_mail_parse_header_finish): assertion failed: ((match[match_idx] & HEADER_MAT CH_FLAG_FOUND) == 0) dovecot: 2009-07-28 08:05:56 Error: IMAP(strr): Raw backtrace: imap [0x48dbf2] -> imap [0x48dc73] -> imap [0x48d346] -> imap(index_mail_parse_header+0x617) [0x4545f7] -> imap [0x483284] -> imap [0x483478] -> imap(i_stream_read+0x2c) [0x491d7c] -> imap(i_stream_read_data+0x46) [0x491f16] -> imap(message_get_body_size+0x108) [0x4885 a8] -> imap [0x4226c3] -> imap(imap_fetch+0x162) [0x420852] -> imap(cmd_fetch+0x23c) [0x41a27c] -> imap [0x41e46c] -> imap [0x41e51d] -> imap [0x41eb25] -> imap(clien t_input+0x63) [0x41efd3] -> imap(io_loop_handler_run+0xcb) [0x49515b] -> imap(io_loop_run+0x18) [0x4945c8] -> imap(main+0x3da) [0x426bea] -> /lib/libc.so.6(__libc_sta rt_main+0xe6) [0x7f2edf08b1a6] -> imap [0x418859] dovecot: 2009-07-28 08:05:56 Error: child 20984 (imap) killed with signal 6 (core dumps disabled)

[Dovecot] expire plugin + --exec-mail in 1.2.6 version
by Nikita Koshikov 25 Nov '09

25 Nov '09

Hello list, After upgrade to dovecot version 1.2.6 I have noticed some quota malfunctions(users become often overquota). Looking at logs closely I have found that quota value resets to general dovecot-config( quota = maildir:Mailbox quota quota_rule = *:storage=500M quota_rule2 = Trash:storage=10%% ), after dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool.sh command. The problem that some users have their own quotas stored in ldap. For example, user sr(a)domain.com have maildirsize before running expire-tool(1G value from ldap): # head -2 /data/mail/domain.com/sr/data/maildirsize 10485760000S 836423205 8285 Then I run expire-tool with mail_debug enabled: # /usr/sbin/dovecot --exec-mail ext /usr/libexec/dovecot/expire-tool.sh Info: Loading modules from directory: /usr/lib/dovecot/imap Info: Module loaded:

In changes to version 1.2.6 I see - dovecot --exec-mail was broken. Is fixes to 1.2.6 touch userdb lookups from --exec-mail ? With 1.2.4 expire-tool works correct and I have no config changes to dovecot setup. If dovecot -n output is needed, please let me know. Thanks.

1. My earlier patch to fix a typo in array.h was not good enough.

[Dovecot] v2.0 lmtp logging
by Pascal Volk 05 Nov '09

05 Nov '09

Hi, I am not yet completely happy with the logging behavior of the lmtp. It logs informative messages like 'lmtp: Info: Connection closed' or 'lmtp: Info: Disconnected for inactivity'. Hm, which server was connected to the lmtp? Who was disconnected for inactivity? I think it would be useful if the lmtp would also log new connections. For example: a) TCP connections: lmtp: Info: Connection: rip=10.1.2.3, lip=10.1.2.5, cid=1255555555.12345 b) Socket connections: lmtp: Info: Connection: via socket, cid=1255555777.10452 rip: There may be multiple SMTP servers in front the IMAP server(s) lip: The lmpt may listen to more than one address cid: The 'connection ID', consists of the current unix time and the pid of the lmtp process. (Or some other values in some other format) The cid should be used in the 'saved' messages. So the delivering MTA would see something like '250 2.0.0 OK: 1255555555.12345 Saved', instead of a message like '250 2.0.0 <jdoe(a)example.com> Saved'. The lmtp should also write the cid to the log. For example: 'lmtp(jdoe): Info: msgid=123, cid=1255555555.12345: saved mail to INBOX' (or discarded because of a matching sieve rule). With this connection ID it would be possible to trace the route which the e-mail has taken. Regards, Pascal -- The trapper recommends today: c01dcafe.0929623(a)localdomain.org

[Dovecot] meaning of parameter imap_idle_notify_interval??
by Ingo Thierack 05 Nov '09

05 Nov '09

Hello, is my understanding of the parameter "imap_idle_notify_interval" right, if i say, it's the time between two point where dovecot tells the client he is here, and sould have nothing directly todo with the notification of new mails arrived. I played with the values around. And the courios is, in thunderbird the folloing. set to 30 seconds. Thunderbird pop up around 25 seconds after the message is deliverd to the inbox. set to 60 seconds. Thunderbird pup up around 50 seconds after the message is deliverd to the inbox. I switch over from archiveopteryx, where no such delay was. Regards, Ingo
