Outlook 2010 woes
by Bryan Holloway 12 Oct '16

12 Oct '16

Hello, everyone. We have recently begun migrating folks from an older server to a newer one, and things have been going quite well except for -- you guessed it -- Outlook 2010 users. Specifically it appears to be one customer in particular, and this particular customer has many nested mailboxes and lots of e-mail in general. Not sure if this is a factor. Old server: * Ubuntu 10.04.4 LTS * Dovecot 2.1.13 * Maildir++ * Local auth via passwd/shadow files New server: * Debian GNU/Linux 8.6 * Dovecot 2.2.13 * Maildir++ * Quotas enabled * LDAP Basically what's happening is that users are seeing large delays when navigating between different IMAP folders. So, for example, user "X" is sitting idle in their INBOX. If they then click on another folder there's a good 6-7 second delay before you can view its contents. If you immediately then navigate to other folders, you get a rapid response. But if the client then goes idle again for 10+ seconds, you will get this delay again. Some are reporting the OS saying "Outlook is not responding." (Everyone is running Windows 7.) Disclaimer: Yes, I know Outlook 2010 is a giant steaming pile of ____. However, everything worked dandy with Dovecot 2.1 and of course my customer is harping on this fact. Things I have tried/read about in the Dovecot list: * Check headers only -- doesn't seem to help. * Had a user completely remove their IMAP profile and re-add: no change. * Had a user set up an entirely new account on a new computer: same symptoms. * Someone mentioned to enable the "delay-newmail" workaround in 20-imap.conf, but this wasn't enabled in our 2.1 install, so that seems like it would not help our case. I was looking through the release notes of later Dovecots, and I noticed that in 2.2.14 there's mention of some issues with Outlook that were fixed, but it wasn't particularly specific about which versions. Should I be looking into that? And if so, is there a separate repository for newer dovecot? Currently the standard Debian 8.6 only has 2.2.13. Any help, suggestions, or pointers would be greatly appreciated. Thank you! - bryan

Problems with GSSAPI and LDAP
by Juha Koho 12 Oct '16

12 Oct '16

Hello, I have a Dovecot 2.2.25 set up with OpenLDAP back end. I was trying to set up a GSSAPI Kerberos authentication with the LDAP server but with little success. Seems no matter what I try I end up with the following error message: dovecot: auth: Error: LDAP: binding failed (dn (imap/host.example.com(a)EXAMPLE.COM)) Local error, SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (No Kerberos credentials available (default cache: FILE:/tmp/dovecot.krb5.ccache)) I have set the import_environment in dovecot.conf: import_environment = TZ CORE_OUTOFMEM CORE_ERROR LISTEN_PID LISTEN_FDS KRB5CCNAME=FILE:/tmp/dovecot.krb5.ccache And these in LDAP configuration: dn = imap/host.example.com(a)EXAMPLE.COM sasl_bind = yes sasl_mech = gssapi sasl_realm = EXAMPLE.COM sasl_authz_id = imap/host.example.com(a)EXAMPLE.COM I have tried with different values in dn and sasl_authz_id and also leaving them out completely but I always end up with the error message above. Using simple bind without GSSAPI works just fine. The credentials cache file exists and is valid for the principal imap/host.example.com(a)EXAMPLE.COM. The file is owned by dovecot user so it shouldn't be a permission problem either. GSSAPI in OpenLDAP works but I suppose it is irrelevant here since the connection attempt never reaches the LDAP server due to the error. I also have similar setup for Postfix and it works fine. Any ideas what to try next? Best regards, Juha

Managesieve port 4190 not working
by Marcio Vogel Merlone dos Santos 12 Oct '16

12 Oct '16

Hi all, I am working on a fresh install with Ubuntu 16.04 LTS and Dovecot 2.2.22-1ubuntu2.1. I am unable to open port 4190, just 2000. I have this on 20-managesieve.conf: protocols = $protocols sieve service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } } service managesieve { process_limit = 1024 } protocol sieve { mail_debug=yes } This way I get only port 2000, if comment out the "sieve_deprecated" section leaving just the "inet_listener sieve" I get nothing. Could not find anything useful on logs or strace. Any hint? Thanks in advance, best regards. -- *Marcio Merlone*

Quota & prefetch uiserDB questions
by Cédric ML 12 Oct '16

12 Oct '16

Hello, I'm trying to make quota work on my dovecot server. I'm using prefetch userdb (source : http://wiki2.dovecot.org/UserDatabase/Prefetch) with a database located on a remote host : passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } userdb { driver = prefetch } userdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } With password_query containing (source : http://wiki2.dovecot.org/Quota/Configuration) : password_query = SELECT \ username AS user, \ password, \ homedir AS userdb_home, \ maildir AS userdb_mail, \ uid AS userdb_uid, \ gid AS userdb_gid, \ CONCAT('*:bytes=', quota) AS userdb_quota_rule \ FROM mailbox \ WHERE username = '%u' When I change the quota value in DB, it's not reflected to maildirsize file of the user. If I delete maildirsize file, it's re-created but not with the quota value which is set in the DB. Questions : how is this maildirsize file created ? how is it updated ? is there a way to make maildir++ quota work with dovecot using prefetch userDB ? Or do I have to use dict quotas ? Many thanks for your help. Regards, Cédric

latest 2.2.25 Hibernation patch raises 100% cpu usage

[imap-login] SSL related crashes using the latest 2.2.25
by Adi Pircalabu 07 Oct '16

07 Oct '16

I'm running Dovecot as proxy in front of some IMAP/POP3 Dovecot & Courier-IMAP servers and in the last couple of days I've been seeing a lot of imap-login crashes (signal 11) on both 2.2.18 and 2.2.25, all SSL related. The following backtraces are taken running 2.2.25, built from source on a test system similar to the live proxy servers.

[feature suggestion] pigeonhole - sendmail path for outgoing email
by krzf83＠gmail.com 06 Oct '16

06 Oct '16

pigeonhole seems to use /usr/sbin/sendmail for its outgoing emails - even tought that is does not seem to be documented anywhere. How about setting to specify diffrent sendmail program path and parameters?

doveadm reload kicked proxy/director users
by Peer Heinlein 06 Oct '16

06 Oct '16

We just noticed, that a doveadm reload kicked all existing imap-sessions on our Dovecot Director. We're surprised about that, because shutdown_clients is set to NO. Is there any way to reload a config change without kicking all IMAP sessions?
