[Dovecot] example-config mail_log plugin options
by Lutz Preßler 09 May '11

09 May '11

Hello, dovecot-2.0.12/doc/example-config/conf.d/10-logging.conf contains # mail_log plugin provides more event logging for mail processes. plugin { # Events to log. Also available: flag_change append #mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename # Group events within a transaction to one line. #mail_log_group_events = no # Available fields: uid, box, msgid, from, subject, size, vsize, flags # size and vsize are available only for expunge and copy events. #mail_log_fields = uid box msgid size } "mail_log_group_events" seems to be gone (when and why?). And it's now "save" instead of "append", with "mailbox_create" also available.

09 May '11

Hello I got this error message yesterday evening for a user I've checked LDA error log it happened 6 times in 3 days for 5 differents users, not much but I wonder what's going on as actually the server is moderately loaded ( Easter holidays ) we have currently 250/300 IMAP processes , in "normal" production time we have approx 1000 IMAP processes running. Apr 14 19:24:37 imap(xxxxxxx): Error: FETCH [] for mailbox Drafts (Hugues at ESIEE) UID 17836 got too little data: 16384 vs 18012 Apr 14 19:24:37 imap(xxxxxxx): Error: Corrupted index cache file /var/cache/dovecot/index/xxxxxxx/.imap/Drafts (Hugues at ESIEE)/dovecot.index.cache: Broken virtual size for mail UID 17836 The machine is supposed to be HUDGE for our 4000 mailboxes HP Proliant DL380 G7 , 12 Gb RAM 24 cores !!! I've located index/cache files on another disk than users mailboxes mailboxes are living on a 2Tb RAID array ( 50% full ) index/cache are living on another single disk ( 10% full ) I run Dovecot 2.0.11 + dovecot2-pigeonhole compiled from FreeBSD 8.2 ports Dovecot or hardware problem ??? Thanks a lot for any ideas/infos

by Michael M Slusarz 09 May '11

As of 2.0.12, looks like NONEXISTENT response code isn't working properly again. Previously brought up issues relating to this here: http://markmail.org/message/jxbgdfv26pws66og With a nonexistent mailbox "FOO", I see this: 1 DELETE "FOO" 1 NO Mailbox doesn't exist: FOO // Should be: 1 NO [NONEXISTENT] Mailbox doesn't exist: FOO 2 RENAME "FOO" "BAR" 2 NO Mailbox doesn't exist: FOO // Should be: 2 NO [NONEXISTENT] Mailbox doesn't exist: FOO michael

[Dovecot] Encoding dovecot keywords
by Алексей Сундуков 06 May '11

06 May '11

Hello. If mailbox name include non latin chars, dovecot save it encode to modification UTF-7. Example "тест" convert to "&BEIENQQ6BEEEQg-". If replace & to + I can decode it: <?php $str = '+BEIENQQ6BEEEQg-'; echo iconv('UTF-7', 'UTF-8', $str); ?> But I can't understand what encoding use dovecot for keywords? I set "тест" (number 5) keyword: cat dovecot-keywords 0 &bcienqrbbeiepgqybdaetw-_&bdwenqrcbdoema- 1 test 2 $label1 3 $label2 4 $label3 5 &beienqq6beeeqg- but "&beienqq6beeeqg-" do not convert to "тест". Why?
