[Dovecot] postfix, dovecot, samba, winbind
by Denis Witt 01 Mar '13

01 Mar '13

Hello List, we're currently working on the migration of our LDAP/Samba3-Domain to Samba4-Active-Directory. So far everything works fine. Postfix can deliver Mails using ProxyAddresses-Information from the AD and Dovecot delivers the mail. Unfortunately when Postfix tells Dovecot to deliver the mail he submit the username without the AD-Domain part: Feb 28 17:17:59 tpdc postfix/pickup[30396]: 5DDAE2C0C2B: uid=0 from=<root> Feb 28 17:17:59 tpdc postfix/cleanup[30402]: 5DDAE2C0C2B: message-id=<20130228161759.5DDAE2C0C2B(a)mx0.concepts-and-training.de> Feb 28 17:17:59 tpdc postfix/qmgr[30395]: 5DDAE2C0C2B: from=<root(a)concepts-and-training.de>, size=463, nrcpt=1 (queue active) Feb 28 17:17:59 tpdc dovecot: lda(dwitt): msgid=<20130228161759.5DDAE2C0C2B(a)mx0.concepts-and-training.de>: saved mail to INBOX Feb 28 17:17:59 tpdc postfix/local[30404]: 5DDAE2C0C2B: to=<dwitt(a)concepts-and-training.de>, orig_to=<denis.witt(a)cat06.de>, relay=local, delay=0.24, delays=0.1/0.01/0/0.13, dsn=2.0.0, status=sent (delivered to command: /usr/lib/dovecot/deliver) Feb 28 17:17:59 tpdc postfix/qmgr[30395]: 5DDAE2C0C2B: removed So Dovecot saves the Mail to "/var/mail/dwitt/", which is fine for me. The Problem kicks in when I try to read my Mail. Dovecot uses "TESTDOM\dwitt" as username and so he didn't find the Mailbox and create a new one in "/var/mail/TESTDOM\dwitt". I tried to fix it with auth_username_translation and auth_username_format but it doesn't work. Any ideas? Thanks!

[Dovecot] help needed with dovecot authentication
by peter lawrie 01 Mar '13

01 Mar '13

Hi I have been asked to configure an dedicated rhel6 server for a customer. I did not realise when I took this on how complicated it was going to be! The purpose of the server is to host a group of websites for small businesses. It came with postfix-2.6.6-2.2 dovecot-2.0.9 and mysql-2.1.67-1 I have installed virtualmin 3.98, usermin1.540-1 and horde 5 About a dozen currently inactive websites have been set up, mail is in /home/<domain>/Maildir My problem is that I can telnet to postfix to send and receive emails and can see these within postfix in webmin I have been having many problems getting dovecot to connect successfully to postfix. I have also installed horde 5 which requires to authenticate to an imap server - that is dovecot. This one server is intended to provide all services, so plain authentication is fine. But I can't use /etc/passwd as the users are in virtualmin I tried configuring ssl, with self-certification so the browser interface is https: At the moment I've restored dovecot.conf and conf.d/10-master.conf, 10-auth.conf and 10-mail.conf to their original settings. So an attempt to login through usermin gives me this Feb 28 19:44:19 scotz1 dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Feb 28 19:44:19 scotz1 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so Feb 28 19:44:19 scotz1 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_mysql.so Feb 28 19:44:19 scotz1 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Feb 28 19:44:19 scotz1 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libmech_gssapi.so Feb 28 19:44:19 scotz1 dovecot: auth: Fatal: sql: Configuration file path not given Feb 28 19:44:19 scotz1 dovecot: master: Error: service(auth): command startup failed, throttling Previous to restoring the conf files I was getting this from horde Feb 28 17:55:02 scotz1 dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Feb 28 17:55:02 scotz1 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so Feb 28 17:55:02 scotz1 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_mysql.so Feb 28 17:55:02 scotz1 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Feb 28 17:55:02 scotz1 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libmech_gssapi.so Feb 28 17:55:02 scotz1 dovecot: auth: Debug: auth client connected (pid=25627) Feb 28 17:55:02 scotz1 dovecot: auth: Debug: client in: AUTH#0111#011PLAIN#011service=imap#011secured#011lip=127.0.0.1#011rip=127.0.0.1#011lport=143#011rport=439 54#011resp=dGVzdHNjb3R6LmNvLnVrAHRlc3RzY290ei5jby51awBwYXNzd29yZA== Feb 28 17:55:02 scotz1 dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Feb 28 17:55:02 scotz1 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so Feb 28 17:55:02 scotz1 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_mysql.so Feb 28 17:55:02 scotz1 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Feb 28 17:55:02 scotz1 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libmech_gssapi.so Feb 28 17:55:02 scotz1 dovecot: auth: Debug: passwd(testscotz.co.uk,127.0.0.1): lookup Feb 28 17:55:02 scotz1 dovecot: auth: passwd(testscotz.co.uk,127.0.0.1): unknown user Horde is using mysql for its database, but I don't particularly care what dovecot uses, although it seems sensible to do the same I have created and removed several mysql databases during my attempts to get this to work. I would greatly appreciate some assistance with this as every 'howto' I have found by googling describes different setups and just gets me deeper in the mire! I want an authentication mechanism on this one server that virtualmin users and horde users (same people!) can use for imap mail. I thought I knew what I was doing before I took this one on (I have configured and manage a dozen centos servers), but this one is making my head spin. Yours in hope! Peter Lawrie

[Dovecot] Disallow Deletion from Trash Folder
by Bradley Rintoul 01 Mar '13

01 Mar '13

Hello: I've been tasked with trying to find a way to keep users from ever "permanently" deleting emails. The users are running Thunderbird and are using the "Archive" option for when emails are deleted. However, they are still able to delete emails from the Archive folders... I'm wondering if there's any way that I can configure Dovecot to make sure that emails *never* get removed from the filesystem. I know it's probably kind of a bizarre request, but is there any way that Dovecot can help me out in this regard? Thanks! B. Rintoul

[Dovecot] Support for PolarSSL?
by Charles Marcus 01 Mar '13

01 Mar '13

Hey Timo, Just curious if you ever thought about supporting other than just OpenSSL? PolarSSL looks really interesting, has no major dependencies and is very lightweight compared to OpenSSL, GNUTLS or others... https://polarssl.org/ I guess it could be a lot of work, or not, anyway, I'm just curious... -- Best regards, */Charles/*

[Dovecot] Best practice for sieve script synchronization
by Oli Schacher 01 Mar '13

01 Mar '13

We consider deploying a two server active-active setup with dsync replication for ~2500 users. I was wondering how people handle sieve script synchronization in such setups. We came up with a few options for syncing: 1) rsync/unison ~/sieve every x seconds 2) move sieve dirs to separatate partition and sync with gluster or drbd 3) patch roundcube managesieve sieve plugin to upload to both managesieve servers (only roundcube can access managesieve in our setup) 4) store sieve scripts in mysql and patch roundcube managesieve plugin to directly access the db instead of using managesieve (we tried this, but apparently sieve scripts read from db via dovecot dict can't have more than one line? show stopper due to roundcube sieve plugin needing comments to parse the scripts) 5) wait until Timo/Stephan add additional magic to dsync for sieve scripts as discussed in http://www.dovecot.org/list/dovecot/2011-October/061699.html ;-) We are tending towards 1) as this seems simplest and most robust solution but before we re-invent the wheel we'd like to "hear" your thoughts... Thanks Oli -- This message does not contain horse meat

[Dovecot] sieve /editheader / addheader :last crash
by Peter Rindfuss 01 Mar '13

01 Mar '13

Hi Everybody, I'm using dovecot 2.1.14 from http://xi.rename-it.nl/debian/ with debian squeeze stable. In general, sieve works fine for me, but "addheader :last ..." from the editheader extension causes a crash when it processes a message. I was able to narrow this down a bit: It only happens if "addheader :last" is the first editheader command executed in a script. If it is preceded by any "deleteheader" or "addheader" without ":last", everything is fine. This is what I get from sieve-test when it crashes: sieve-test(root): Panic: file istream.c: line 133 (i_stream_read): assertion failed: (_stream->skip != _stream->pos) sieve-test(root): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x4881a) [0x7f5e0b37681a] -> /usr/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x32) [0x7f5e0b376902] -> /usr/lib/dovecot/libdovecot.so.0(i_error+0) [0x7f5e0b349f7f] -> /usr/lib/dovecot/libdovecot.so.0(i_stream_read+0x17c) [0x7f5e0b37da9c] -> /usr/lib/dovecot/libdovecot.so.0(+0x51453) [0x7f5e0b37f453] -> /usr/lib/dovecot/libdovecot.so.0(+0x5150e) [0x7f5e0b37f50e] -> /usr/lib/dovecot/libdovecot.so.0(i_stream_read+0x69) [0x7f5e0b37d989] -> /usr/lib/dovecot/libdovecot.so.0(+0x53fe1) [0x7f5e0b381fe1] -> /usr/lib/dovecot/libdovecot.so.0(i_stream_read+0x69) [0x7f5e0b37d989] -> /usr/lib/dovecot/libdovecot.so.0(i_stream_read_data+0x52) [0x7f5e0b37dc72] -> /usr/lib/dovecot/libdovecot.so.0(io_stream_copy+0x41) [0x7f5e0b38ae21] -> /usr/lib/dovecot/libdovecot.so.0(+0x5e1de) [0x7f5e0b38c1de] -> /usr/lib/dovecot/libdovecot.so.0(o_stream_send_istream+0x33) [0x7f5e0b38acb3] -> /usr/lib/dovecot/libdovecot-storage.so.0(maildir_save_continue+0x38) [0x7f5e0be0caf8] -> /usr/lib/dovecot/libdovecot-storage.so.0(mail_storage_copy+0xb8) [0x7f5e0be376d8] -> /usr/lib/dovecot/libdovecot-storage.so.0(maildir_copy+0x56) [0x7f5e0be086c6] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_copy+0x4a) [0x7f5e0be3ce9a] -> /usr/lib/dovecot/libdovecot-sieve.so.0(+0x3fa66) [0x7f5e0c103a66] -> /usr/lib/dovecot/libdovecot-sieve.so.0(+0x366b4) [0x7f5e0c0fa6b4] -> /usr/lib/dovecot/libdovecot-sieve.so.0(sieve_result_execute+0x3ff) [0x7f5e0c0fabef] -> /usr/lib/dovecot/libdovecot-sieve.so.0(sieve_execute+0x56) [0x7f5e0c10b456] -> sieve-test(main+0x73e) [0x403a5e] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7f5e0abdec8d] -> sieve-test() [0x403219] Aborted Best regards Peter

But I tried to create a fresh account in Dovecot (not migrated from Courier), and it still shows a intermixed folder order: a list "" * * LIST (\HasNoChildren) "/" "Spam" * LIST (\HasNoChildren) "/" "Sent" * LIST (\HasNoChildren) "/" "Drafts" * LIST (\HasNoChildren) "/" "Trash" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "Pub" a OK List completed. So, it is not a migration problem -- note that it is the LIST command output, so it is not got influenced by some IMAP client folder searchlist/mask or its namespace settings (like in Thunderbird) WBR, valery

[Dovecot] patch for crash while FTS-searching through virtual mailbox
by Mike Abbott 28 Feb '13

28 Feb '13

FTS-searching through a virtual mailbox crashes dovecot-2.1.15 when the FTS backend does not support lookup_multi. src/plugins/fts/fts-api.h says for fts_backend_lookup() that "The arrays in result must be initialized by caller." FTS backends can therefore assume that the arrays are initialized by their caller. However, fts_backend_lookup_multi() does not initialize the per-box arrays before calling the FTS backend’s lookup function. This patch fixes the resulting crash. --- dovecot-2.1.15/src/plugins/fts/fts-api.c 2012-08-03 09:09:28.000000000 -0500 +++ dovecot/src/plugins/fts/fts-api.c 2013-02-28 14:35:43.000000000 -0600 @@ -337,8 +337,12 @@ result->box_results = p_new(result->pool, struct fts_result, i+1); for (i = 0; boxes[i] != NULL; i++) { + struct fts_result *box_result = &result->box_results[i]; + p_array_init(&box_result->definite_uids, result->pool, 32); + p_array_init(&box_result->maybe_uids, result->pool, 32); + p_array_init(&box_result->scores, result->pool, 32); if (backend->v.lookup(backend, boxes[i], args, - and_args, &result->box_results[i]) < 0) + and_args, box_result) < 0) return -1; } return 0;
