Hello, >>> Lucene library is throwing an error, which crashes Dovecot. Maybe Dovecot >>> should catch the error, but it would still be broken. Try deleting the lucene indexes and rebuilding them? >> Deleting the indexes helped, but after they had been rebuilt, the error occurred again. > Could you enable core dumps and run bt full in gdb?

Dictionary quota with Flat file database
by Sam 30 Jun '16

30 Jun '16

Hello, I want specific quotas for certain users and I looking for doing that with dictionary quota backend and Flat file. Because I am using "active directory" with PAM for authenticate, I can't get per-user quota limits with set/override them by returning "quota_rule" extra field from userdb. I started reading http://wiki1.dovecot.org/Quota/Dict, saw some good stuff... The problem is that I don't understand how to set the limit in the users files. If I open one created file I only see the current number of messages and the actual size. Not the quota limits... vi /home/vmail/john.doe/Maildir/dovecot-quota : priv/quota/messages 13 priv/quota/storage 600201 Here is /etc/dovecot/conf.d/90-quota.conf file details : plugin { # I think I have to set the default limits here quota_rule = *:storage=10G:messages=10000 } ... plugin { quota = dict:user::file:%h/Maildir/dovecot-quota # same result with : # quota = dict:User::file:%h/Maildir/dovecot-quota } my server : CentOS Linux release 7.2.1511 dovecot : dovecot-2.2.10-5.el7.x86_64 Thanks for helping.

Unread Mail flag being reset frequently with dovecot -git master-2.2
by Reuben Farrelly 30 Jun '16

30 Jun '16

Hi again, I'm experiencing problems with the Dovecot git master-2.2 branch, in which mails that have been previously read are randomly appearing as unread. This happens slowly and affects more and more emails the more changes that occur to a mailbox. I am using Maildir format and on Gentoo Linux x86_64 on local disks. Usually only a few at a time change their status - and it seems to be random which ones lose their read status. Typically though they are the most recent emails that have been delivered in the past few months (I haven't yet seen this occur with any really old emails). This problem is MUA independent, it can be observed with Thunderbird as well as Roundcube. If I go in and mark all mails as read then they will show as read for a short while until they too slowly start become 'unread' again. Currently I'm running git rev from https://github.com/dovecot/core/commits/master-2.2 : f292589f4b85e02d97d974dfe34324c6c0bb9d9f (I can't run anything newer due to an SSL symbol error which I reported earlier). This rev: b1254dfe442639236f881afae85e0739520ab409 Is known to be good, so the problem started happening somewhere between these two. (I know there are a lot of in-between revisions, but bisecting that could take days of time). Dovecot config is up at: http://www.reub.net/files/dovecot/thunderstorm-dovecot.conf Rawlog debug files are at http://www.reub.net/files/dovecot/rawlogs/ Hopefully someone else may have seen this happen before. Are there any other debugs I can gather which will help get to the bottom of this? Reuben

Yes "dovecot purge" is certainly my mistake in the script but it really works completely analogous "doveadm purge" probably why I did not notice the difference before :) It looks like it just launches the doveadm in this case. Adding slashes after asterisks unfortunately they also adds to the variable and the script gives an error like "doveadm(user/(a)example.org/): Error: User doesn't exist" Thanks for the idea , I think it will be now more correctly : === #!/bin/sh cd /backup/MailRoot/dovecot/domains || exit 1 for i in * do if [ -d $i ]; then cd $i for j in * do if [ -d $j ]; then dovecot purge -u $j@$i fi done cd .. fi done === >Четверг, 30 июня 2016, 13:53 +03:00 от Alexander Moisseev <moiseev(a)mezonplus.ru>: > >On 30.06.16 12:51, Николай Мананков wrote: >> -----screenshot begin----- >> >> mail:/etc/cron.daily # cat ./dovepurge.sh >> #!/bin/sh >> >> cd /MailRoot/dovecot/domains >> >> for i in * >> do >> cd $i >> for j in *; do dovecot purge -u $j@$i; done >> cd .. >> done >> >> -----screenshot end ----- >> >It might be worth to add slashes after asterisks to process only directories. >Does "dovecot purge" actually work? > >-----screenshot begin----- > >#!/bin/sh > >cd /MailRoot/dovecot/domains || exit 1 > >for i in */ > do > cd $i > for j in */; do doveadm purge -u $j@$i; done > cd .. >done > >-----screenshot end ----- > >> It is strange that the daemon does not do this automatically, and even setting up autoexpunge option does not help.

[patch] Support redis AUTH
by Dave 30 Jun '16

30 Jun '16

A very minor patch to support redis AUTH (for all that's worth) using an extra password= field. I'm not sure if this will be of any value to anyone here. We're testing it in development and "it works for us" but it's yet to be used in anger. Sorry if I'm going about this the wrong way, I tried emailing this directly but heard nothing back; so I'm reposting to the list as I'm honestly not sure what established protocol is regarding code contribution. -- Dave

filtering ssl_cert
by Russell Stuart 30 Jun '16

30 Jun '16

In dovecot 1 I was able to do something like this: protocol imap { ssl_cert = cert-imap.pem ssl_key = key-imap.pem } local ww.xx.yy.zz { protocol imap { ssl_cert = cert-imap-ww.xx.yy.zz.pem ssl_key = key-imap-ww.xx.yy.zz.pem } } The intent is ww.xx.yy.zz is an externally routable IP address which has a Cert signed by a real CA, other addresses are internal which have a variety of domain names, signed by a self-signed cert. That worked in dovecot 1, but in dovecot 2 I get the error: "Conflict in setting ssl_cert found from filter". Weirdly, this works in dovecot 2: local 0.0.0.0/0 { ssl_cert = cert-imap.pem ssl_key = key-imap.pem } local ww.xx.yy.zz { ssl_cert = cert-imap-ww.xx.yy.zz.pem ssl_key = key-imap-ww.xx.yy.zz.pem } But this doesn't: local 0.0.0.0/0 { protocol imap { ssl_cert = cert-imap.pem ssl_key = key-imap.pem } } local ww.xx.yy.zz { protocol imap { ssl_cert = cert-imap-ww.xx.yy.zz.pem ssl_key = key-imap-ww.xx.yy.zz.pem } } It smells like a bug. Anyway, does anybody know of a way to port my config to dovecot 2?
