[Dovecot] Dovecot write activity (mostly 1.1.x)
by mikkel＠euro123.dk 04 Nov '07

04 Nov '07

Im experiencing write activity thats somewhat different from my previous qmail/courier-imap/Maildir setup. This more outspoken in v.1.1.x than v1.0.x (Im using Maildir). Write activity is about half that of read activity when measuring throughput. But when measuring operations its about 5-7 times as high (measured with zpool iostat on ZFS). I think this might be due to the many small updates to index and cache files. Anyway since writing is much more demanding to the disk than reads dovecots ends up being slower (only a little though) than my old qmail/courier-imap/Maildir was. And the old setup didnt even benefit from indexes like Dovecot does. (What I mean saying slower is that it can service fewer users before it hits the wall). Of course theres also lots of benefits using Dovecot. Im just wondering whether this was a thing that should be focused on for later versions (maybe writes could be grouped together or something like that). Dovecot is very cheap on the CPU side so the only real limit in terms of scalability is the storage. Regards, Mikkel

[Dovecot] Sieve error messages (sieve 1.1.2, dovecot 1.1b6)
by mikkel＠euro123.dk 04 Nov '07

04 Nov '07

Sorry for spamming the list today:) Im getting a lot of these errors in the deliver log: deliver([recipient]): [date] Info: sieve runtime error: Fileinto: Generic Error deliver([recipient]): [date]:18 Error: sieve_execute_bytecode([path-to-sieve]) failed deliver([recipient]): [date] Info: msgid=<[msgid] >: save failed to [foldername]: Quota exceeded In this case the account is over the defined Dovecot quota limit. Dovecot knows what to do but sieve seems to throw its standard error message. Is there something wrong with Sieve or is it just that the error is misleading? This has been present in all v1.1.x I think (some changes was made to the error messages in b3 or b4 but believe this didnt change). Regards, Mikkel

[Dovecot] *notify config for 1.0.x doesn't enable inotify
by Paolo 03 Nov '07

03 Nov '07

hi, the current code has changed include linux/inotify.h to sys/inotify.h since 2006-01-17, but that won't work with inotify*.h as documented in the wiki. One has to either revert back to linux/inotify.h, or add #include <sys/inotify-syscalls.h> to both configure.in and src/lib/ioloop-notify-inotify.c Or, just symlink sys/inotify.h -> linux/inotify.h. That's on Debian 3.1 (Sarge). -- paolo GPG/PGP id:0x1D5A11A4 - 04FC 8EB9 51A1 5158 1425 BC12 EA57 3382 1D5A 11A4

[Dovecot] IMAP vs system username logging with checkpassword auth
by dale gallagher 03 Nov '07

03 Nov '07

Hi After upgrading to dovecot 1.0.7 I noticed that the actual username is no longer logged, but rather the system user (in my case 'vmail') under which my virtual set-up runs. Now I'm unable to see which virtual users log in. Any pointers on how to configure dovecot to log the actual username given during the IMAP dialogue would be appreciated. My dovecot.conf includes the following: auth default { mechanisms = plain passdb checkpassword { args = /var/qmail/bin/qmail-vauth } userdb prefetch { } user = auth } An example logfile entry: 2007-11-03 15:41:56.027191500 dovecot: Info: imap-login: Login: user=<vmail>, method=PLAIN, rip=192.168.0.141, lip=192.168.0.10, TLS

[Dovecot] MANAGESIEVE patch v8 for dovecot 1.0.7
by Stephan Bosch 02 Nov '07

02 Nov '07

Hello dovecot users, I have updated the MANAGESIEVE patch to the latest stable version of dovecot (1.0.7). This new version also adds extra configuration settings to explicitly specify the location of the sieve storage and the active sieve script. Additionally, the README now more clearly explains the configuration of the daemon. It currently won't compile with 1.1 due to significant changes in the master code. However, because 1.1 now approaches a stable release, the next version is going to be updated to version 1.1. Change Log V8 ------------- + Fixed a few incompatibilities with 1.0.7 version. For instance, the "Logged in" message is now sent by the -login process and not by the managesieve daemon anymore. This caused a segfault every once in a while. + Probably fixed the settings problem reported by Steffen Kaiser regarding login_dir. 'dovecot -n' now reports correct results, but testing will show whether the whole problem is solved. + The managesieve daemon now accepts the sieve_storage and sieve configuration settings, so it is now possible to explicitly configure the location of the sieve storage and the active script respectively. The daemon still falls back to using the mail_location (MAIL) settings if nothing else is specified. + The cyrus timsieved does not use the + character in string literals and many clients have adopted to this behaviour. The latest managesieve (08) advises to accept a missing + from clients. The server should not send any + characters as well. This behavior is now implemented on the server. + Cleaned up sieve-storage.c: split up the sieve_storage_create function in various sub-functions for obtaining the various paths and directories. + Forced manual intervention if rescueing a non-symlink file at the active script path fails somehow. Previously, this presented the admin with a log message that it had just eaten the script, which is not very nice. + Restructured the README.managesieve file and added some more explanation with regard to the configuration of the daemon. This patch still includes (yet another) instance of the CMU Sieve source, as explained in one of my previous e-mails (http://dovecot.org/list/dovecot/2006-July/015016.html) The patch can be downloaded at: http://sinas.rename-it.nl/~sirius/dovecot-1.0.7-MANAGESIEVE-v8.diff.gz The README.managesieve is located in the root of the dovecot source tree after applying the patch. Have fun testing the patch. Don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl IRC: Freenode, #dovecot, S[r]us

[Dovecot] Listening only on localhost
by tobias-mail＠gmx.net 02 Nov '07

02 Nov '07

Hi! I've got dovecot 1.0.rc15. I want dovecot to listen only on localhost for imap, and on any interfaces for imaps. So I put the following into my config: protocol imap { listen = 127.0.0.1:143 ssl_listen = *:10993 .. } dovecot -n correctly reports: listen: 127.0.0.1:143 ssl_listen: *:10993 But I can still do a 'telnet MY_HOST 143' from the outside, and 'netstat -pltn | grep dovecot' reports: [ip changed ;)] tcp 0 0 77.my.ip.253:10993 0.0.0.0:* LISTEN 4847/dovecot tcp 0 0 77.my.ip.253:143 0.0.0.0:* LISTEN 4847/dovecot Am I doing something wrong?

[Dovecot] caching custom headers (via plugins)
by Paolo 02 Nov '07

02 Nov '07

hi, currently dovecot caches on disk some most common headers. Is it possible to tweak such headers list via plugins, eg to cache custom X-* headers, or do I need to hack the actual index/cache src? if so, which are the .c/.h files to touch? thanks -- paolo GPG/PGP id:0x1D5A11A4 - 04FC 8EB9 51A1 5158 1425 BC12 EA57 3382 1D5A 11A4

[Dovecot] Errors in Dovecot 1.0.5
by Jeff Tucker 02 Nov '07

02 Nov '07

Hello, I am running Dovecot 1.0.5 and seem to have lots of errors in my Dovecot logs. The worst errors are things like: Oct 30 16:11:42 delta2 dovecot: IMAP(x): Corrupted transaction log file /home/spamcop-net2/deputies/dovecot.index.log: end_offset (392) > current sync_offset (388) Oct 30 16:11:42 delta2 dovecot: IMAP(x): file mail-index-sync-update.c: line 841 (mail_index_sync_update_index): assertion failed: (view->hdr.messages_count == map->hdr.messages_count) Oct 30 16:11:42 delta2 dovecot: IMAP(x): Raw backtrace: imap [0x462a7e] -> imap [0x46234c] -> imap(mail_index_sync_update_index+0x7b2) [0x44a982] -> imap(mail_index_sync_commit+0xe7) [0x447f87] -> imap(maildir_sync_index_finish+0xd2) [0x420b32] -> imap [0x4225af] -> imap(maildir_storage_sync_init+0x63) [0x4227b3] -> imap(imap_sync_nonselected+0xf) [0x41be9f] -> imap(_cmd_select_full+0xc5) [0x413f95] -> imap(cmd_select+0xb) [0x41411b] -> imap [0x415a87] -> imap [0x415b2c] -> imap(_client_input+0x75) [0x415cd5] -> imap(io_loop_handler_run+0xee) [0x4684ce] -> imap(io_loop_run+0x2d) [0x46797d] -> imap(main+0x3e3) [0x41d7b3] -> /lib/libc.so.6(__libc_start_main+0xdb) [0x2aaaaace049b] -> imap [0x410cca] When this happens, my users just get timeouts trying to do stuff. I have my messages (maildirs) and indices all stored on NFS. For locking, I have mmap_disable = yes and lock_method = dotlock Do you have any idea what is going on here? In general, I get tons of errors about corrupted transaction log files for all users. Is this normal? Thanks Jeff
