gssapi considered as PLAIN?
by Harry Schmalzbauer 05 Nov '14

05 Nov '14

Hello, as soon as I set "disable_plaintext_auth = yes", AUTH=GSSAPI vanishes from capabilities. ([CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=GSSAPI AUTH=PLAIN AUTH=LOGIN] vs [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS LOGINDISABLED]) Why? I'm wondering especially because at http://wiki2.dovecot.org/Authentication/Mechanisms, GSSAPI is correctly listed under “Non-plaintext authentication“. Thanks, -Harry

ntlm_auth seems ok, initial auth failure with dovecot2 (and winbind 4.1.13)
by Harry Schmalzbauer 05 Nov '14

05 Nov '14

Hello, I've read quite often that there are problems with ntlm_auth helper (last one here http://www.dovecot.org/list/dovecot/2014-June/096561.html) But haven't found any confirmation, neither it's working for anybody else nor that it's known taht this issue needs debuging. Like for ohers, my authentication tests from the commandline with ntlm_auth exactly give expected results. But initial authentication (with Outlook) fail at first, but after entering the user's password, nevertheless succeeds with mech=NTLM. See the attached ntlm-log.txt Can't exactly tell when this regression occured, one year ago nobody had to enter his password, it worked like intended with Outlook (which still is version 2010). Any idea how to debug? It could be also a regression in samba, both highly appreciated applications were upgraded at the same time… Thanks, -Harry

calling post-login script with doveadm
by Héctor Moreno Blanco 05 Nov '14

05 Nov '14

Hello everyone, I'm trying to execute some commands with doveadm but I need some information loaded in a post-login script before running these commands. Is possible to run the post-login script while executing doveadm? I've found how to do something similar with -o key=value to override settings, but I want to change a namespace location, as done in the post-login script: ... export USERDB_KEYS="$USERDB_KEYS namespace/archivo/location" exec env "NAMESPACE/ARCHIVO/LOCATION=$location" "$@" ...

Public mailbox confusion
by Stefan G. Weichinger 05 Nov '14

05 Nov '14

greets, I am quite sure I ask some faq here ... sorry, but I am confused by the many options and choices here. What I want to do is: I migrate lots of public folders from a MS Exchange Server ... The customer wants that there is a "Public" folder containing all these hundreds of folders, the public folder should be visible for all the dovecot-users and all the subfolders should be automatically subscribed as soon a new user logs in. What I have now: namespace { type = private separator = / prefix = inbox = yes } namespace { type = public separator = / prefix = Public/ location = maildir:/home/vmail/public:INDEXPVT=/home/vmail/public/index/%d/%u/index subscriptions = yes } As far as I see from testing this doesn't yet work that way. When I open the mailbox with eg. roundcube I see "Public" but nothing below it ... Could someone please give me a good pointer here? Thanks! Stefan

sieve replication and .dovecot.lda-dupes
by Jan Behrend 05 Nov '14

05 Nov '14

Hello list, I have a replicated dovecot with two servers. People seem to get vacation responses more often then it is specified in "days: XX", depending on which dovecot instance they receive the incoming mail. Is ".dovecot.lda-dupes" replicated? The other problem is that the vacation response is coming from the wrong address depending on which field the recipient was listed: "to:" or "cc:" Here is my test example: g9-rz has the vacation rule set up: date | mail -s test -r jbehrend(a)mpifr-bonn.mpg.de -c g9-rz(a)mpifr-bonn.mpg.de jan(a)flatpick.de and this returns this vacation response: ### snip ### Return-Path: <> Delivered-To: <jbehrend(a)mpifr-bonn.mpg.de> Received: from mail2.mpifr-bonn.mpg.de ([134.104.18.60]) by mailbox2.mpifr-bonn.mpg.de (Dovecot) with LMTP id +pgPDzm1WFSn9wAAvl5QjA for <jbehrend(a)mpifr-bonn.mpg.de>; Tue, 04 Nov 2014 12:16:13 +0100 X-Sieve: Pigeonhole Sieve 0.4.2 Message-ID: <dovecot-sieve-1415099773-541512-0(a)mailbox1.mpifr-bonn.mpg.de> Date: Tue, 04 Nov 2014 12:16:13 +0100 From: jan(a)flatpick.de To: <jbehrend(a)mpifr-bonn.mpg.de> Subject: Vacation In-Reply-To: <E1Xlc5t-0001LT-Bu(a)jb1.mpifr-bonn.mpg.de> References: <E1Xlc5t-0001LT-Bu(a)jb1.mpifr-bonn.mpg.de> Auto-Submitted: auto-replied (vacation) Precedence: bulk MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 8bit X-Evolution-Source: 1385020682.6450.3@jb1 Ain't here!

With as much information as you already have in your database schema you may want to look at using the Prefetch userdb. http://wiki2.dovecot.org/UserDatabase/Prefetch P.S. Apologies for the duplication. I forgot to reply to the list with my last response.

SSL Client authentication with trustcenter-certificate
by dovecot.pkoch＠dfgh.net 04 Nov '14

04 Nov '14

Dear reader, we are using dovecot 2.2.7 and like it very much. Authentication is done via a checkpassword program that does two things: 1) check wether the client has connected via SSL using a client certificate 2) check wether the client is using a one time password generator Most of our users are using certificates that we have created ourself. These certificates contain a x500uniqueidentifier. But some users are using certificates from a german trust center and these certificates do not contain a x500uniqueIdentifier nor something similar. I would like to map these certificates to user accounts and my first idea was to do so from my checkpassword programm. But how do I find out the client-certificate from within a checkpassword script. I tried to add an additional entry to auth_request_var_expand_static_tab and fill in that environment variable in auth_request_get_var_expand_table_full() (both in src/auth/auth-request.c). But where do I find the SSL-context from which I can extract the client certificate? Kind regards Peter Koch

Released Pigeonhole v0.4.6 for Dovecot v2.2.15.
by Stephan Bosch 02 Nov '14

02 Nov '14

Hello Dovecot users, Version 0.4.5 introduced one new 'feature', but it caused build problems. This release fixes that. If you've successfully installed 0.4.5, you do not need to upgrade. Changelog v0.4.6: - After make distclean, the distributed tarball would fail to recompile. This causes problems for some distribution builds. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.6.tar… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.6.tar… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

Released Pigeonhole v0.4.5 for Dovecot v2.2.15.
by Stephan Bosch 02 Nov '14

02 Nov '14

Hello Dovecot users, Unfortunately, Pigeonhole v0.4.4 had a rather big issue with error handling and the execution of the implicit keep. This problem presented itself for example when users exceeded their quota. This did not result in the proper rejection message. This is why I quickly release a new version. Changelog v0.4.5: + Added a Pigeonhole version banner to doveconf output. This way, future bug reports will also include Pigeonhole version information. - Fixed handling of implicit keep. Last version erroneously reported that implicit keep succeeded after an earlier failure, while it in fact had failed. Particularly occurred for mailbox quota errors. - Fixed segfault occurring on SunOS systems when there is no active script. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.5.tar… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.5.tar… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

Sa-learn-pipe.sh script modification
by Pierre Barre 01 Nov '14

01 Nov '14

Hello, I've seen on this wiki page: http://wiki2.dovecot.org/Plugins/Antispam A script called "sa-learn-pipe.sh". I've tested it but it slow things down because dovecot wait for the script termination. So, I've made a modification. Now, the task is running in the background and dovecot move the mail without waiting for the script termination: #!/bin/bash echo /usr/bin/sa-learn $* /tmp/sendmail-msg-$$.txt echo "$$-start ($*)" >> /tmp/sa-learn-pipe.log #echo $* > /tmp/sendmail-parms.txt cat<&0 >> /tmp/sendmail-msg-$$.txt /usr/bin/sa-learn $* /tmp/sendmail-msg-$$.txt && rm -f /tmp/sendmail-msg-$$.txt & echo "$$-end" >> /tmp/sa-learn-pipe.log exit 0 I want know if this can cause any problem ? Thanks. -- Best regards, Pierre Barre.

SSLv3 attack on pop3?
by Hans Morten Kind 31 Oct '14

31 Oct '14

We turned off SSLv3 support on our pop/imap running dovecot on Oct 16th, we did check that all users where using TLSv1 and there have been no complaints (except one old windows-phone). But at 13:00 UTC today, suddenly strange entries is seen in the logfile: Error: SSL: Stacked error: error:140943F2:SSL routines:SSL3_READ_BYTES:sslv3 alert unexpected message: SSL alert number 10 Followed by: pop3-login: Disconnected (no auth attempts in 2 secs) user=<>, rip= Some 20 ips have been seen so far, all ips are uniq and none have used our server lately. Just one resoved and it's name ends .cn, some lookups with whois leads to the same origin for all. This makes me anxious that some have made some poodle-like thing for pop3? hmk

vpopmail, open_smtp_relay and non-PLAIN auth mechs
by Jim Jagielski 31 Oct '14

31 Oct '14

I've noticed that if using the vpopmail auth setup, that the roaming-user functionality provided via open_smtp_relay() is only done if the auth mechanism is PLAIN. For example, if the client authenticates via DIGEST-MD5, the open relay file is not updated, as it should be. This is due to the call to open_smtp_relay only being done via vpopmail_verify_plain(). Instead, imo, that call should be done in auth_request_success() in the auth-request.c file, so that it is done however the authentication is done, as long as it is successful. Attached is a patch for 2.2.15. Let me know if attachments are not the preferred method and I'll cut/paste. tia! -- Jim Jagielski

Can someone explain this Sent thread sorting?
by Philip Rhoades 31 Oct '14

31 Oct '14

People, I attach a screen capture of my RoundCubeMail Sent box - why does the second item on the list, which is a separate reply to the thread above it, get sorted to position 2? By the date, and being a single mail, it should be much further down the screen . . I presume it is because the Subject is the same? Thanks, Phil. -- Philip Rhoades GPO Box 3411 Sydney NSW 2001 Australia E-mail: phil(a)pricom.com.au

Question wrt. dovecot replicator
by Remko Lodder 30 Oct '14

30 Oct '14

Hi People, I recently setup a replication service within dovecot between two machines in different datacenters, which has the following configuration; (yes it is hashed out, because I needed to) #service replicator { # unix_listener replicator-doveadm { # mode = 0666 # } # process_min_avail = 1 #} # #service aggregator { # fifo_listener replication-notify-fifo { # mode = 0666 # #user = vmail # } # unix_listener replication-notify { # mode = 0666 # #user = vmail # } #} # #service doveadm { # inet_listener { # port = 12346 # } #} # ##doveadm_port = 12346 #doveadm_password = XXXXXXX #replication_max_conns = 30 # and a mail_replica = tcp:host{a,b}:12346 configuration on each host so that they are pointing to eachother; This seems to work fine for most accounts, for example: I never experienced issues with this. However, several other accounts (with a large variety of clients) got duplicated emails. Looking with doveadm I only noticed that the numbers of the messages are closely related to eachother but one number incremented. So they cannot be deleted with the deduplicator function. The replication is provided over TCP only, the connection streams over an OpenVPN tunnel so that the contents are protected, the machines are located in different Datacenters but close to eachother. How can I determine why there are duplicated emails? What kind of messages should I specifically look for? Can I set this up for a few selected accounts instead of all accounts like it was currently? To make sure I do not make things worse for others then needs to be :-) The service had been disabled for the time being to prevent the other users from getting duplicated emails. Thanks for the advice in advance!

different mail location in different namespace
by Héctor Moreno Blanco 30 Oct '14

30 Oct '14

Hello everyone, We have Dovecot 2.1.6. With different Namespaces: ... mail_location = maildir:%h/Maildir ... namespace { separator = . prefix = inbox = yes type = private } namespace { inbox = no location = prefix = INBOX. separator = . hidden = yes type = private list = no } namespace { location = maildir:/buzon/archivo/%u/_ARCHIVO prefix = _ARCHIVO. hidden = yes separator = . type = private } We take the attribute "home directory" from the LDAP in the userdb attributes. We would like to modify this attribute for the Namespace ARCHIVO. For example, if a home directory is /buzon/buzon1/11111111, the mail location for ARCHIVO would be /buzon/archivo1/11111111. Is this modification possible without adding another attribute at the LDAP (just editing the attribute)? Thank you very much in advanced. Kind regards. Héctor Moreno.

Bug in the combination of Lazy_expunge and acl plugin
by Philipp Faeustlin 30 Oct '14

30 Oct '14

Hello Timo, Hello Dovecot Developers, Hello everyone on the list, I think I have some bug, because I haven't found a working configuration till now. I use latest dovecot 2.2.13 from the dovecot-ee repository, with acl and the lazy_expunge plugin. My configuration for shared folders work fine with lazy_expunge disabled. If I enable lazy_expunge and the user (named userA), which I'm testing with, got no shared folders, then lazy_expunge is working as supposed. Now I add some shared folder for example per doveadm: doveadm acl set -u userB(a)domain.de INBOX user=userA(a)domain.de lookup read write write-seen write-deleted insert expunge create After that every list command fails with: Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/' '.EXPUNGED/' is the name for the namespace of lazy_expunge. Easiest way for me to reproduce the error is: doveadm mailbox list -u userA(a)domain.de which results in: ----------------- Trash Drafts Sent doveadm(userA(a)domian.de): Fatal: lazy_expunge: Unknown namespace: '.EXPUNGED/' ------------------ I hope someone can confirm this behavior and or give me some hints to get rid of it. Regards Philipp Fäustlin

Bug in fts (solr?, Maildir?) incorrect last_indexed_uid
by Karl O. Pinc 30 Oct '14

30 Oct '14

Hi, I thought I should document this. (Dovecot 2.2.9, see config at bottom.) I installed dovecot and then converted a number of mbox mailboxes to Maildir, and had a number of pre-existing Maildir mailboxes. I then installed the debian (wheezy) fts-solar and jetty packages, and tested my inbox using the "telnet localhost imap ... 3 SEARCH text "test" method as described on the dovecot wiki. Everything seemed to work. But when I used balsa to search a mailbox other than my inbox, I got no results. "doveadm dump" on the searched mailbox showed that "last_indexed_uid" to be the last uid of my inbox. Stopping dovecot, deleting out the dovecot-index* files, starting dovecot, and re-running "doveadm dump" showed a non-existant last_indexed_uid -- that is, last_indexed_uid did not show up in the dump output. Using the telnet method above to attempt to search again yielded no results, but this time (I think, I also tried various times with balsa) the last_indexed_uid value was that of the last uid in my trash mailbox. I don't believe I'd yet tried fts on my trash. Using balsa as an imap client the results were very consistent; every Maildir where "doveadm dump" returned no last_indexed_uid value had the last_indexed_uid set to that of the inbox's largest uid. Running "doveadm fts rescan -u foo" fixed the problem. (FWIW, now all the Maildirs seem to have a last_indexed_uid=0.)
