[Dovecot] Dovecot 2.0 progress?
by Guy 21 Jul '10

21 Jul '10

Hi, Been having a look at the roadmap on the wiki for Dovecot 2.0 and I was wondering how that's progressing? Are you able to offer a guesstimate on how far it is from stable Timo? Just asking because we're moving to new servers soon and I'm considering using the opportunity to switch from Dovecot/Maildrop/Maildir to Dovecot/deliver/mdbox if 2.0 is likely to be reasonably safe to use in the next month or so. Thanks Guy -- Don't just do something...sit there!

Hi In http://wiki.dovecot.org/Variables I found: %s service imap, pop3, smtp, deliver and that can be use in userdb and SQL query string. How exactly can I use %s in the query string if I want for ex to disable a service (just one service - ex pop3) for a specific user. Alex

[Dovecot] Dinamic 'mail_location' for each user
by Thiago Henrique 21 Jul '10

21 Jul '10

Hello, I have a lot of domains in a mail server, so I make a balanced allocation of mailboxes in the storage disks. That improves performance of access to records. Therefore, I want to overwrite 'mail_location' directive for each user. But I also want to use the modifier 'H' to spray the mailboxes of the same partition in a hash. Then, each user has your own 'mail_location' that I would like load from database. Like this: mdbox:/var/spool/imap/partition1/%256HRu/%u:INDEX=/var/lib/imap/user/% 256HRu/%u partition1 is in range [partition1 .. partiton7] In my tests the '%256HRu/%u' kind of 'mail_location' is not being interpreted by Dovecot. Can Dovecot to interpret 'mail_location' load from database ? Thank you. -- []'s Thiago Henrique Network Administration Digirati Networks K8 Networks

[Dovecot] Login process connection routing
by Brandon Davidson 20 Jul '10

20 Jul '10

Timo, Just out of curiosity, how are incoming connections routed to login processes when run with: service imap-login { service_count = 0 } I've been playing with this on our test director, and the process connection counts look somewhat unbalanced. I'm wondering if there are any performance issues with having a single process handle so many connections. It seems fine (system load is actually lower than with service_count = 1), but I thought I'd ask. /usr/sbin/dovecot \_ dovecot/imap-login \_ dovecot/imap-login [1 connections (1 TLS)] \_ dovecot/imap-login \_ dovecot/imap-login [5 connections (5 TLS)] \_ dovecot/imap-login [1 connections (1 TLS)] \_ dovecot/imap-login [4 connections (4 TLS)] \_ dovecot/imap-login [1 connections (1 TLS)] \_ dovecot/imap-login [1 connections (1 TLS)] \_ dovecot/imap-login [315 connections (315 TLS)] \_ dovecot/imap-login [63 connections (63 TLS)] \_ dovecot/imap-login [12 connections (12 TLS)] \_ dovecot/imap-login \_ dovecot/imap-login [10 connections (10 TLS)] \_ dovecot/imap-login [2 connections (2 TLS)] \_ dovecot/imap-login [370 connections (370 TLS)] \_ dovecot/imap-login [24 connections (24 TLS)] -Brad

[Dovecot] Doveadm director flush/remove
by Brandon Davidson 20 Jul '10

20 Jul '10

I've got a couple more issues with the doveadm director interface: 1) If I use "doveadm director remove" to disable a host with active users, the director seems to lose track of users mapped to that host. I guess I would expect it to tear down any active sessions by killing the login proxies, like I'd done 'doveadm direct add HOSTNAME 0 && doveadm director flush HOSTNAME' before removing it? Here's what I see with an active open connection: [root@cc-popmap7 ~]# doveadm director status brandond Current: 10.142.0.179 (expires 2010-07-14 01:26:14) Hashed: 10.142.0.179 Initial config: 10.142.0.161 [root@cc-popmap7 ~]# doveadm director remove 10.142.0.179 [root@cc-popmap7 ~]# doveadm director status brandond Current: not assigned Hashed: 10.142.0.174 Initial config: 10.142.0.161 2) "doveadm director flush" returns the wrong usage: [root@cc-popmap7 ~]# doveadm director flush doveadm director remove [-a <director socket path>] <host> 3) "doveadm director flush" all breaks the ring: [root@cc-popmap7 ~]# doveadm director flush all Jul 14 01:26:33 cc-popmap7 dovecot: director: Error: Director 10.142.0.180:1234/right disconnected Jul 14 01:26:33 cc-popmap7 dovecot: director: Error: Director 10.142.0.180:1234/left disconnected Jul 14 01:26:33 oh-popmap7 dovecot: director: Error: director(10.142.0.162:1234/left): Invalid HOST-FLUSH args Jul 14 01:26:33 oh-popmap7 dovecot: director: Error: director(10.142.0.162:1234/right): Invalid HOST-FLUSH args For some reason, flushing a host address only disconnects one side: [root@cc-popmap7 ~]# doveadm director flush 10.142.0.160 Jul 14 01:28:23 cc-popmap7 dovecot: director: Error: Director 10.142.0.180:1234/right disconnected Jul 14 01:28:23 oh-popmap7 dovecot: director: Error: director(10.142.0.162:1234/left): Invalid HOST-FLUSH args -Brad

[Dovecot] [dovecot] Dovecot Migration so far
by Mark Moseley 20 Jul '10

20 Jul '10

We've been doing our own beta testing of Dovecot 2.0-beta4 IMAP (both direct IMAP and webmail-fronted), and we've had nothing but glowing compliments from our beta users/victims. I've also been running a lone box with the latest mercurial build and that's been running just fine too. All mail data is on NFS, but I've put indexes on the local disk, which has worked just dandy so far. Everything's been great and all I've seen amiss are a few random problems -- all of which are are barely impacting us and I mention only for the sake of feedback. All boxes are Debian Lenny i386, running 2.6.33.1. One oddity is that I see lots of messages like this (I've obfuscated paths/IPs/usernames, so assume paths are all actually correct) for a variety of different mailboxes prior to their indexes directory getting initially created: Apr 02 13:25:24 imap(mail@box): Error: creat(/var/tmp/Indexes/14/75/mail(a)box/dovecot.mailbox.log) failed: No such file or directory Judging by the mtimes of the containing directories, the directory was created a couple of seconds after the error gets logged, so I'm guessing mailbox_log_alloc is just getting called too early. It obviously just happens that first time. Doesn't seem to actually be hurting anything, that I can tell. One other kind of weird thing I saw was that originally I had my indexes on a dedicated partition with ext4 (Debian Lenny, i386, 2.6.33.1), I was seeing scattered messages like this: Mar 29 18:02:38 imap(mail@box): Error: FETCH [] for mailbox INBOX UID 3244 got too little data: 1116 vs 1087383 Mar 29 18:02:38 imap(mail@box): Error: Corrupted index cache file /var/tmp/Indexes/12/dc/mail(a)box/.INBOX/dovecot.index.cache: Broken virtual size for mail UID 3244 The message corresponding with UID 3244 was around 1116 bytes (+32 bytes, IIRC), so no clue where the 1087383. In all the cases of that error I saw, the lefthand number of bytes was very closer to correct and the righthand was way way off, and the S= flag in the filename was correct too. I'm guessing that the random righthand number was just due to corrupted cache. When I reformatted that partition as ext3, the error went almost completely away (just a few total over the past few days, as opposed to a few per hour when it was on ext4). I don't even have an educated guess as to why that'd happen. A wild guess would be that ext4's delayed allocation was causing problems. Even under ext4, it was still pretty rare and only, say, 1 out of 100 imap logins. And ext3 performance on the indexes partition so far has been just fine, so I don't plan on switching back to ext4 -- though if anyone has any experience with putting indexes on reiserfs and/or xfs versus ext3, I'd love to hear your thoughts. I've also seen a couple of these in the past few days (on beta4, not repo version -- haven't been running repo version long enough to say if it'd do the same): Mar 31 21:52:54 imap(mail@box): Error: fdatasync(/mail/username/mail@box/Maildir/dovecot-uidlist) failed: Input/output error Mar 31 21:52:54 imap(mail@box): Error: Raw backtrace: /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot.so.0 [0xb77c0b71] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot.so.0 [0xb77c0bef] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot.so.0(i_error+0) [0xb77c0ea8] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_begin_to+0x9a9) [0xb7837ca9] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_begin+0x56) [0xb7837d56] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0(maildir_sync_index_begin+0x51) [0xb78734d1] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0 [0xb78716eb] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0(maildir_storage_sync_force+0x4d) [0xb78719bd] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0(maildir_uidlist_lookup+0x96) [0xb7877646] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0 [0xb787215a] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0(maildir_sync_index+0x7f0) [0xb78729d0] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0 [0xb78715b6] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0(maildir_storage_sync_init+0x162) [0xb7871b92] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0(mailbox_sync_init+0x39) [0xb7815759] -> dovecot/imap [mail@box 215.108.28.102 UID](imap_sync_init+0x54) [0x805efa4] -> dovecot/imap [mail@box 215.108.28.102 UID](cmd_sync_delayed+0x223) [0x805f2a3] -> dovecot/imap [mail@box 215.108.28.102 UID](client_output+0xb6) [0x8056de6] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot.so.0 [0xb77d5d4a] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xf5) [0xb77cd1d5] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot.so.0(io_loop_run+0x30) [0xb77cc220] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot.so.0(master_service_run+0x2a) [0xb77b9e1a] -> dovecot/imap [mail@box 215.108.28.102 UID](main+0x1c5) [0x805f8e5] -> /lib/libc.so.6(__libc_start_main+0xe5) [0xb764d455] -> dovecot/imap [mail@box 215.108.28.102 UID] [0x804e621] Mar 31 21:52:54 master: Error: service(imap): child 4500 killed with signal 6 (core dumps disabled) In 4 days of beta testing with a fair number of users, I've seen maybe 4 of these backtraces total, so not exactly a big issue.
