curious when certain patches might become part of a release
by Benjamin Connelly 13 Feb '15

13 Feb '15

We ran in to this same problem others discussed in this thread: http://dovecot.org/list/dovecot/2014-November/098927.html and have also applied the patches (31262a892ba7 and 80ed82a93c1a) and it seems to have stopped the panics. We usually just use the FreeBSD ports tree to install software, so I'm looking forward to the time when we can go back to that. Will those patches be part of the next release? Benjamin

[SOLVED] Thunderbird client certification validation fails with same profile but changed IMAP server software (Re: It works for two SMTP servers and cyrus-imap, why not Dovecot?)
by Daniel Dickinson 13 Feb '15

13 Feb '15

In hopes that searching may turn up the solution for others: The reason client certificate validation was failing in Thunderbird when it had previously succeeded with other servers (both IMAP and SMTP) is precisely that: the client and profile where the same ones used to connect to the server who's hostname hadn't changed, and email addresses and usernames were the same, and Thunderbird can't handle that. Keeping your existing Thunderbird profile when switching the IMAP server software running on the hosting server doesn't work even if you change all the configs that should matter (rename old accounts out of the way, replace the server they are supposed to be contacting with blank, and so on) and create new accounts within the same profile. The workaround for this bug in Thunderbird is to move the old profile out of the way and start fresh. The apparent cause of failure (invalid cert messages and other messages that make it look like it's a configuration or certificate/CA file issue) actually has nothing to do with the actual issue and is a major red herring. Sorry for the noise, back to regular scheduled program... Regards, Daniel On 2015-02-12 6:29 AM, Daniel Curran-Dickinson wrote: > Ok, the patch doesn't actually fix the bug.

Howto NTML
by Mark Foley 13 Feb '15

13 Feb '15

Has anyone gotten NTLM working with Dovecot and Outlook? I have a Samba4 domain controller / active directory running just fine on Linux Slackware64 14.1. PLAIN authenticiation works just fine if I create /etc/passwd accounts for the domain users. I've tried for over two weeks to get NTLM working from Outlook 2007 on a domain workstation without success. I end up with various permission errors and ultimately procmail won't deliver if I "adjust" mailbox folder permissions too liberally. Also it seems I have to log in each time in Outlook. If someone has made this work, I'd be very interesting in seeing the doveconf -n output, the permissions on the mailbox directories, the nsswitch.conf, and anything else you had to tweak to get this working. I'd really love to have AD authentication working on this setup! --Mark

Enabling mod-sequences
by Luca Bertoncello 13 Feb '15

13 Feb '15

Hi list! I have Dovecot 1.2.9 from Ubuntu repositories on my server. Now I installed Horde and it give me sometimes the error "Mailbox does not support mod-sequences". Well, I must say, that I didn't know these mod-sequences, but I can' know all... Well, the question now is: how can I enable the support of the mod-sequences on the mailboxes of my Server? I searched in the Dovecot-Wiki, but I didn't found anything... Thanks a lot for your help Luca Bertoncello (lucabert(a)lucabert.de)

Dovecot dsync not replicating ".dovecot.sieve -> .sieve/managesieve.sieve" / setactive
by Martin Štefany 12 Feb '15

12 Feb '15

Hello, I've ran into problem with Dovecot and dsync replication. Everything works perfectly, including replication of sieve scripts, except fact that if user activates the 'managesieve' ruleset (I'm using currently Roundcubemail) on "mail1" host, it wouldn't be activated on "mail2" host, by creating symlink ".dovecot.sieve -> .sieve/managesieve.sieve". I've also tried to use 'replication_full_sync_interval', but symlink is not created anyway. I found 2 references already for this problem, but none came to any conclusion: http://dovecot.org/pipermail/dovecot/2014-June/096650.html http://www.dovecot.org/list/dovecot/2014-September/097857.html Here is the output from 'doveconf -n' from both hosts for reference :: mail1 :: # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux

[Patch] Allow for more than one recipient_delimiter (a la postfix 2.11)
by Lennart Weller 12 Feb '15

12 Feb '15

Hey everyone, as my previous emails apparently got stuck in a spam filter I'll try this again. The patches attached here allow for more than one recipient delimiter in the address. Which is allowed in postfix since version 2.11. E.g. lhw+postfix(a)ring0.de would be equal to lhw-postfix(a)ring0.de if configured that way. Same as postfix only the first discovered delimiter is taken into account and the priority is first to last in the list. Lennart

Controlling inactivity timeout for IMAP
by Joseph Tam 12 Feb '15

12 Feb '15

I have a problem with a user who uses a wireless carrier that keeps changing his IP as he travels throughout the city. From the perspective of our dovecot IMAP server, the user keeps logging in from another IP, and after a short while, hits up against the mail_max_userip_connections limit. It takes 30 minutes before those orphaned connections times out. Is there any way to decrease the IMAP idle timeout other than to recompile dovecot with a new value? imap-common.h:#define CLIENT_IDLE_TIMEOUT_MSECS (60*30*1000) For example, will this work? service imap { idle_kill = 600 } Joseph Tam <jtam.home(a)gmail.com>
