[Dovecot] Dovecot LDAP issue
by Deeztek Support 08 Apr '14

08 Apr '14

Dovecot version: 2.0.19 ------------------------------------------------------- grep -v '^ *$#.*$\?$' /etc/dovecot/dovecot-ldap.conf hosts = server.domain.tld:389 ldap_version = 3 auth_bind = yes dn = vmail(a)domain.tld dnpass = somepassword base = ou=testou,dc=domain,dc=tld scope = subtree deref = never user_filter = (&(userPrincipalName=%u)(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) pass_filter = (&(userPrincipalName=%u)(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2))) pass_attrs = userPassword=password default_pass_scheme = CRYPT user_attrs = =home=/var/vmail/vmail1/%Ld/%Ln/Maildir/,=mail=maildir:/var/vmail/vmail1/%Ld/%Ln/Maildir ----------------------------------------------------- I'm authenticating users through AD and it seems to work with no problems. Unfortunately, when I try to send e-mail from a user who's not in the testou container I get the following error: Sender address rejected: User unknown in virtual mailbox table> #SMTP#. I'm assuming this happens because dovecot is not able to to lookup up that user since that user is outside the testou container. A lot of the AD users are in different places inside the AD structure and I need to be able to configure dovecot to look from the root of the AD structure down. I changed the base to this: base = dc=domain,dc=tld but it simply fails to lookup any users at that point. How would I go about getting dovecot to start at the top of the domain and look at every nested OU within AD? thanks a lot D

[Dovecot] Debugging doveadm expunge
by Andy Hawkins 08 Apr '14

08 Apr '14

Hi, I'm a recent convert to dovecot, and in general it is all working fine. However, I have a number of cron jobs set up to purge old messages from mailboxes. These don't seem to be doing what I would expect. Is there any way of debugging this process? Some way of seeing what messages it's checking, and why each one matches or fails to match? For example, I'm running this: doveadm expunge -u andy mailbox "News Reports" savedbefore 90d from the crontab of user 'andy'. I'd expect the specified folder to only contain 90 messages (I get one 'News Report' per day) but in actual fact there are 1428 in there! Any advice would be appreciated. Thanks Andy

[Dovecot] dsync replication questions
by Nikolaos Milas 07 Apr '14

07 Apr '14

I am running two servers with Dovecot v2.2.12 on CentOS x86_64 (5.10 and 6.5 respectively) and users are virtual over ldap. I have setup our main internal server (vmail.example.com) with dsync replication according to the first part of http://wiki2.dovecot.org/Replication. The second one (vmail1.example.com) will be the failover server which we want to be a real-time mirror (but can be manipulated directly and it should propagate changes back to vmail.example.com) When I started the server (vmail.example.com) mirroring started and completed fine (after a few hours). However, since then, I am not seeing a continued mirroring between the two. I would expect changes to one of the masters to be propagated in real time to the other - which does not happen. If I manually run (on vmail.example.com) dsync -u imaptester mirror ssh -l root vmail1.example.com dsync -u imaptester then these two accounts are synced. Question 1: Shouldn't mirroring continue automatically in real time (having configured it as in the first part of http://wiki2.dovecot.org/Replication)? If not, what should I do to enable such a real-time (or near-real-time) sync? Note that I have not configured "replication_dsync_parameters" as noted at the above page. Question 2: Where can I find documentation about "replication_dsync_parameters" and about "the doveadm sync command" (referred to at the same page)? I have not been able to locate such a documentation/wiki page. Question 2a: What do options "-d -N -l 30 -U" signify in "replication_dsync_parameters = -d -N -l 30 -U"? Thanks, Nick

[Dovecot] Dovecot IMAP Authentication issue with Vpopmail
by Arup 07 Apr '14

07 Apr '14

Hello All, i've configured a qmail server (for office) under Ubuntu 12.04 server following this guide- http://www.connor.net.au/tutorials/qmail/qmaillite/ everything working just fine except dovecot IMAP. i've followed this section for dovecot- http://www.connor.net.au/tutorials/q...te/dovecot.php<http://www.connor.net.au/tutorials/qmail/qmaillite/dovecot.php> but when i go to telnet 143 and try to login with username/password, it failed and showing error: ** BYE Internal error occurred. Refer to server log for more information.Connection closed by foreign host.* i think there may be some authentication issue with vpopmail and dovecot. POP and SMTP both working. but why not IMAP? i can't also use webmail (i.e. squirrelmail) as it don't working with IMAP. it's showing- *connection dropped by IMAP server *error while trying to login. i'm looking forward to a solution here. any qmail+vpopmail expert here? plz help. Thanks in advance. B/R

[Dovecot] Unknown setting: plugin after fresh install
by Patrik Karisch 04 Apr '14

04 Apr '14

Hi guys, I've installed dovecot 2.1.7 on a Debian Wheezy, tweaked some parameters little bit, but I can't restart it (dovecot -n also fails) and get this error: doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/90-acl.conf line 11: Unknown setting: plugin doveconf: Error: managesieve-login: dump-capability process returned 89 Wether I uncomment this plugin line, I get the error on another file (example 90-quote.conf). Seems a little bit weird. What have I done false? Thanks Patrik -- PRIVACY IS NOT A CRIME! So please encrypt your emails using PGP/GnuPG.

[Dovecot] mdbox with mail_attachment_dir per user in 2.2.12
by Pavel Stano 04 Apr '14

04 Apr '14

Hello, we have 2 netapp arrays with 2 volumes and we need to store our mail data in one or other volume for every user. We want keep data for one user in one volume only. So we would like to have 2 separate mail_attachment_dir, one on every volume. But in latest version 2.2.12 it look like it is only possible to set one global mail_attachment_dir. I have an idea with 2 separate dovecot instances per machine with different mail_attachment_dir. Or it is possible to somehow specify it per user ?

[Dovecot] imap / IPv6 problems?
by Egbert 04 Apr '14

04 Apr '14

Hi, I have this intermittant problem. When sending an email it *sometimes* takes ages before the process finishes. The process seems to hang in moving the message to the sent items" folder". When I disable the IPv6 stack in the network config (this is MS Windows 7), the hanging process immedialetely completes! This makens me think that is has to do with the IP stacks. Another observed effect is a long "rotating wheel" when just klicking on an imap folder before the listing in the right pane updates. Here the same trick solves the problem. I use Thunderbird on W7 as client and have my mail (3 accounts) on a remote mailserver. I have full control over that server which can become handy... Th emailserver is Ubuntu 12.04 LTS with postfix and Dovecot (2.0.19) from the standard repo's. My IPv6 connections is a native IPv6 from my ISP (xs4all.nl). I have no reason to think that the IPv 6 connecition itself is the problem. Any advise to investigate this problem is welcome. Egbert Jan, NL
