by Frank Bonnet 09 May '11

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

[Dovecot] NONEXISTENT handling
by Michael M Slusarz 09 May '11

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?

[Dovecot] calling dovecot exported auth from Java
by WJCarpenter 30 Apr '11

30 Apr '11

As far as I have been able to figure out, dovecot auth always works over a Unix domain socket. I believe it is not currently possible to operate dovecot auth over an Internet domain (TCP) socket. Am I correct? I want to call dovecot's exported authentication from a Java application. Java doesn't natively know how to talk to a Unix domain socket, so there are inconveniences. There are 3rd party JNI libraries to allow Java to do it, but I'm not too wild about the idea of using JNI. My current thinking is to rig up some kind of proxy/shuttle arrangement between a localhost TCP port and the dovecot auth Unix domain socket in the filesystem. I'm looking at using the more or less standard tool "socat" to do that. ('m on a mainstream Linux distribution.) Has anyone else confronted and solved this problem? Do tell us the details .... :-) TIA!
