[Dovecot] No NTLM with PAM after upgrade
by Phil Quesinberry 01 Mar '13

01 Mar '13

After updating From Dovecot 1.07 (included with CentOS 5) to 2.11, NTLM authentication will not work. Attempts to authenticate against Samba version 4.0.4-GIT-20cb7de also fail with 'auth: Info: winbind(?,192.168.2.100): user not authenticated: NT_STATUS_UNSUCCESSFUL', despite the fact that the same user can sign on to the Samba domain and access files. What I'm really trying to understand here though is why version 1.07 would do NTLM with PAM just fine, but later versions I've tried will not. After failing to get later versions to work, I decided to see if I could at least get them to do NTLM by authenticating against a Samba domain but that won't work either. 1.07 did NTLM just fine authenticating against a system user account with PAM, as demonstrated by the following excerpt from the log: dovecot: Feb 06 12:46:59 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 06 12:46:59 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 06 12:47:42 Info: IMAP(pquesinb): Disconnected: Logged out dovecot: Feb 06 12:47:42 Info: IMAP(pquesinb): Disconnected: Logged out dovecot: Feb 06 12:48:03 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 06 12:48:03 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 06 12:48:44 Info: IMAP(pquesinb): Disconnected: Logged out dovecot: Feb 06 12:48:44 Info: IMAP(pquesinb): Disconnected: Logged out Authentication settings for 1.07 were as follows (excerpt from -n output, see below for full output): auth default: mechanisms: ntlm plain passdb: driver: passwd-file args: /etc/dovecot.users passdb: driver: pam args: cache_key=%u dovecot userdb: driver: passwd Since 1.07 was such an old version, I first tried updating to 1.2.17 and lost the ability to do NTLM authentication with the same settings: Feb 06 16:09:32 dovecot: Info: Dovecot v1.2.17 starting up (core dumps disabled) Feb 06 16:09:46 auth(default): Info: password(pquesinb,192.168.2.100): Requested NTLM scheme, but we have a NULL password Feb 06 16:09:53 auth(default): Info: password(pquesinb,192.168.2.100): Requested NTLM scheme, but we have a NULL password Feb 06 16:10:05 imap-login: Info: Disconnected (auth failed, 2 attempts): user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 Feb 06 16:11:54 auth(default): Info: password(pquesinb,192.168.2.100): Requested NTLM scheme, but we have a NULL password Feb 06 16:12:04 auth(default): Info: password(pquesinb,192.168.2.100): Requested NTLM scheme, but we have a NULL password Feb 06 16:12:16 imap-login: Info: Disconnected (auth failed, 2 attempts): user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 Next I decided to try 2.x and since I had installed 1.2.17 from source, I thought it would be wise to install from an RPM which had been "blessed" for CentOS 5, so 2.1.1 was installed from the RPMs linked to on the Dovecot download site: http://dl.atrpms.net/all/dovecot-2.1.1-2_132.el5.x86_64.rpm Still no NTLM authentication with 2.x using PAM, so I decided to try authenticating against the Samba 4 domain using Samba's winbind daemon and ntlm_auth helper.

[Dovecot] Maildir Control files and quota
by Tabbed Out 01 Mar '13

01 Mar '13

Hello all, the dovecot wiki recommended that the index and control files for maildir be placed on a partition which does not have a quota. I have a VPS which gives me 20 gigs of space. Since space is tight, is there some way to calculate how much space the partition needs for the control and index files? Would 1 gig be sufficient in the long run?

[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

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

Before describing the symptom, let me give you the situation... I'm running Claws-Mail 3.8.1 on Xubuntu 12.10. On the way out I just do normal port 465 SSL to my web host's SMTP server. On the way back, fetchmail grabs my messages from my ISP using IMAP (and erasing them on on the ISP's server after retrieval), then delivers them to procmail, which, based on filters, drops them into the correct directories of the Dovecot server running on my desktop. Claws-mail then views all my email on the IMAP server. slitt@mydesk:~$ dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.5.0-25-generic x86_64 Ubuntu 12.10 ext4 At the bottom of this email I'll put a copy of a typical full header on a post from me. Here's the symptom: Every time I reply to an OCLUG post, Claws-Mail loads the *To* with oclug(a)mailman.oclug.org and the *CC* with oclug(a)penguin.oclug.org. Unless I remember to delete the CC, this makes me double post every time, and must be quite annoying to you all. This happens *only* on OCLUG posts: None of my other mailing lists display this symptom. It's actually weirder than that, because although when I compose the message the preceding is true, by the time I get the two messages back they both say oclug(a)penguin.oclug.org. This happens only with the OCLUG list, no others. I studied the full headers of the two messages when they came back to me, and could discern no difference in the two. What I did find, however, is that all OCLUG messages have: List-Post: <mailto:oclug@mailman.oclug.org> Reply-To: Orange County Linux Users Group <oclug(a)penguin.oclug.org> List-Id: Orange County Linux Users Group <oclug.mailman.oclug.org> Can anyone tell me how to start narrowing down the cause of this behavior?

[Dovecot] Looking for HOWTO for fc18 with postfix/TLS/imaps
by Alex 01 Mar '13

01 Mar '13

Hi all, Does there already exist a document that outlines the best approach to implement postfix with dovecot? I'd like to set up a Maildir system with TLS clients and SMTP Auth. I don't think I need to require client certs, but want to avoid cleartext passwords. It's unclear to me whether to use 143 with TLS or 993. I've currently set it up using 143 with STARTTLS using normal passwords. Is this correct? Can I use a regular apache web cert to provide an authorized cert and key to use for authentication by the clients? Thanks, Alex

[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...

[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;

[Dovecot] header brakage on sieve redirect ?

Hi all, In the sieve file require ["copy"]; redirect :copy "asdf(a)asd.pl"; emails with headers containing \n in non terminated " field like Cc: xxx <xxx(a)plus.pl>, "asd, Grzegorz " <xxxxx(a)nsn.com> Subject: RE: RF after redirecting them Cc: xxx <xxx(a)plus.pl>, "asd,\ \ Grzegorz " <xxxxx(a)nsn.com> Subject: RE: RF mail delivered locally by dovecot-lda is unaltered lack of space before second \ brakes the headers. I'm investigating if this isn't cosed by qmail-inject, but my first suspect is sieve. dovecot 2.0.13, sieve 0.3.3, dovecot-delivery is used as an exclusive lda for qmail Regards, Michal Grzedzicki

[Dovecot] Public free (libre) mailbox hosting service for everybody!
by אנטולי קרס נר 28 Feb '13

28 Feb '13

Hello e-mail software developers and users! I'd like to ask all of you a question. And of course hear relevant opinion. I've been using free software happily for a few years, and I found free/open source alternatives for many popular proprietary tools such as Facebook, Dropbox, Micro$oft Windows & Office, Youtube, Skype and many many others. Some of the alternatives are probably known to some of you, while others are still unknown to many. But I couldn't find a replacement to mailbox hosting. I'm using a Gmail mailbox and I hate it. So many free and open source mail servers and I still use Gmail, a closed-source service (which also probably tracks all my data, including Google searches I do, and uses it for all kinds of statistics and advertising, but that's another issue). So I asked myself, why is there no mailbox hosting service which respects user freedom? I sent an e-mail to the Free Software Foundation, and got a suggestion to ask all of you: do you know any free (libre) mail server out there? If you do, please inform me, and the whole free software community, developers and users. I couldn't find any. If nobody else finds any either, the plan is to start a new server. There are so many server tools and programs, like the ones you use and develop. It's just like hosting a Git repository or videos of pictures for the masses. We can do it with e-mail too. Q: Why don't I start my own personal server? A: I'm a programmer and I can do it - with some effort, but I can. The problem is not me. The problem is that all the non-programmer and non-technical users can't. And they shouldn't. We tech people can, and should, run such servers for everybody. For all users who want their basic freedoms respected. Another question to tech people: I'm not an expert in e-mail software, so I'm not really sure setting up a server is as easy as all other online services we get, such as Diaspora (facebook replacement), MediaGoblin (Youtube replacement), Gitorious (git repo hosting). Is there a technical issue preventing people from running a mail server, or it's just a matter of having enough money to run it, and the necessary technical skills (which many of you probably have). If it's possible, we'll do it. Also, if users had to pay for such a service, it would be okay. I don't mind paying for my free software stack. I'd actually find it a way to contribute back to the people and projects which deserve it. The point is not money; such a service can get funds. The point if FREEDOM. Waiting for response and opinions from you, my fellow free software community members, Anatoly Krasner Free software enthusiast/activist Israel

[Dovecot] Real-time sync using dsync
by Nikolaos Milas 28 Feb '13

28 Feb '13

Hi, Can we use dsync to achieve *continuous* (real-time) sync between two servers (Mirror mode)? Running in such a "continuous" dsync mode, we would replicate two servers to one another continuously, so that the two would be concurrently available/accessible/useable (as POP3/IMAP servers), and getting synced in real time. Is this possible? (If yes, I think it would be much easier to setup such an architecture, rather that resorting to shared file systems, network-based storage etc.) Thanks, Nick

In Courier, we had 'INBOX.' namespace prefix and '.' as a separator. Now we have empty prefix and a '/' as a separator. So, the settings are as follows: namespace { location = maildir:/usr/mailsuite/data/%d/%n type = private separator = / prefix = inbox = yes } But I used the courier-dovecot-migrate.pl script from Timo, as recommended. Where might be the traces of Courier (namespace settings etc.) remained? It seems that Courier and Dovecot use separate sets of files in user mailbox. Maybe, the migrate script expects the settings to be prefix = 'INBOX.' and separator = '.', what we don't want, so, we must modify the migrate script to change namespace settings when migrating?

[Dovecot] IMAP folders sort order
by Valery V. Sedletski 28 Feb '13

28 Feb '13

Hi all We migrated our IMAP server from Courier to Dovecot. The minor problem appeared: Dovecot LIST command now shows mailbox listing in some weird order. (I suppose, it is filesystem directory order) Previously, with Courier, it was sorted, i.e., the INBOX was the first, followed by other system folders. This is not a problem with our webmail, because it sorts folders by its own. But with some IMAP clients, we have folders intermixed. Is there a way to influence the folder sort order in Dovecot? WBR, valery

[Dovecot] dsync with imapc and hidden folders
by Angel L. Mateo 28 Feb '13

28 Feb '13

Hello, I'm trying to use dsync to copy mail from one server to a newer one, so I'm using imapc as source (when running dsync in the destination server). The command I'm using is like this: sudo dsync -vD -o imapc_user="<myuser>*master" -o imapc_password="<master pass>" -o imapc_host=<original server> -o imapc_features=rfc822.size -o mailbox_list_index=no backup -R -f -u "<myuser>" imapc: This command is working. The problem I have is that I'm using lazy_expunge in the original server, and namespace used in the original server has the config: namespace { hidden = yes list = no location = maildir:~/Maildir/expunged prefix = BORRADOS. separator = . } so, it is not being synchronized. I have tried to synchronized from the original server instead of destination with: sudo dsync -vD -o imapc_user="<myuser>*master" -o imapc_password="<master pass>" -o imapc_host=<dest server> -o imapc_features=rfc822.size -o mailbox_list_index=no -o mail_location=maildir:<myuserhome>/Maildir/expunged backup -f -u "amateo" imapc: with this, no message is copied and I have errors like: dsync(<myuser>): Error: Mailbox Archives.2003_kk changed its GUID (e7fc0b2d831e1c51984d000029c62294 -> 7d325fb944b953993df5d27ce2ee786c) Any idea to copy messages in this namespace without needing to make it plubic? Is there any hidden option for dysnc? Could I use doveadm backup? How? (it seems that documentation for dsync and doveadm backup is not updated) -- Angel L.

[Dovecot] Logs when moving mails
by Christian Forjahn 28 Feb '13

28 Feb '13

Hi, I have a problem with an older mailserver. We have an account where 10 Users use one IMAP Account to manage their work. Sometimes some of the emails seem to disappear. I think they are moved somewhere but I can´t tell it for sure. Is there a way to make dovecot logging any movement of emails (I would prefer doing it only for one account). This account is not a local user.

[Dovecot] selinux rules for dovecot
by Robert Moskowitz 28 Feb '13

28 Feb '13

I am running selinux in permissive mode on my new mail server, in part because of dovecot. I would really like to use selinux, but I suspect it may be a challenge. My setup is on Centos 6.3 with dovecot using mysql for virutal domains and users. I am looking for a set of definitive selinux instructions, not a pointer to selinux tutorial. Here are examples of what I am seeing: Feb 27 16:46:08 klovia kernel: type=1400 audit(1362001568.770:33468): avc: denied { search } for pid=2994 comm="dict" name="mysql" dev=dm-0 ino=1705864 scontext=system_u:system_r:dovecot_t:s0 tcontext=system_u:object_r:mysqld_db_t:s0 tclass=dir Feb 27 16:46:08 klovia kernel: type=1400 audit(1362001568.770:33469): avc: denied { write } for pid=2994 comm="dict" name="mysql.sock" dev=dm-0 ino=1706116 scontext=system_u:system_r:dovecot_t:s0 tcontext=system_u:object_r:mysqld_var_run_t:s0 tclass=sock_file Feb 27 16:46:08 klovia kernel: type=1400 audit(1362001568.770:33470): avc: denied { connectto } for pid=2994 comm="dict" path="/var/lib/mysql/mysql.sock" scontext=system_u:system_r:dovecot_t:s0 tcontext=system_u:system_r:mysqld_t:s0 tclass=unix_stream_socket Feb 27 16:46:08 klovia kernel: type=1400 audit(1362001568.771:33471): avc: denied { getattr } for pid=2994 comm="dict" path="/usr/share/mysql/charsets/Index.xml" dev=dm-0 ino=395155 scontext=system_u:system_r:dovecot_t:s0 tcontext=system_u:object_r:usr_t:s0 tclass=file Feb 27 16:46:08 klovia kernel: type=1400 audit(1362001568.771:33472): avc: denied { read } for pid=2994 comm="dict" name="Index.xml" dev=dm-0 ino=395155 scontext=system_u:system_r:dovecot_t:s0 tcontext=system_u:object_r:usr_t:s0 tclass=file

[Dovecot] v2.2.beta2 released
by Timo Sirainen 27 Feb '13

27 Feb '13

http://dovecot.org/releases/2.2/beta/dovecot-2.2.beta2.tar.gz http://dovecot.org/releases/2.2/beta/dovecot-2.2.beta2.tar.gz.sig A ton of fixes since beta1. Especially the new dsync and the replication server related to that should really work now. It also works correctly now for shared mailboxes with private \Seen flags. And the replication server uses incremental syncing after the initial full sync, so it should be pretty efficient also. I've only two things left to do before v2.2.rc1: 1. Implement dsync to work via TCP and TCP+SSL sockets. This is pretty easy to do actually, since it can use the existing doveadm-server to start up. 2. Read up all the pending mails from Dovecot mailing list and fix up the reported issues. Actually I guess most of those are for v2.1, but still I should get around to it. :) There shouldn't be any major bugs left, so I'm expecting v2.2.rc1 out in maybe a week or so, hopefully followed by the final v2.2.0 soon afterwards. Please test and report any bugs found!

[Dovecot] Help with vpopmail authentication
by Fran Márquez 27 Feb '13

27 Feb '13

Hello, Currently I have a qmail server with vpopmail+courierImap. I want setup a new server in DMZ for proxy IMAP connections and I have a doubt with authentication method. I've read that dovecot can use a vpopmail driver for authentication. As my user database/password is stored by vpopmail, I think that this would be the best method for check the auth logins against dovecot. But I've read the docs and many examples availables on WWW and I haven't found any reference to validate against an *external* vpopmail server. The examples configuration doesn't contain any host/port, so I suppose that driver try to use a local vopomaild. In my case, I only want dovecot for proxying IMAP connections to my current mail server, without store mails or user/password info in dovecot server, because all that info is already stored in real mailserver. The ideal scenario would be this: user ---IMAPs----> dovecot ----- IMAP ---> mailserver Any advice will be wellcome. Regards and thank you very much in advance

Re: [Dovecot] Sieve filters on folders, different from INBOX

Really, I looked to mpop options, it can call various LDA's. And, dovecot-lda has "-m" parameter, which allows to specify the mailbox name. So, I can deliver the mail arrived by fetcher, via dovecot-lda, and Sieve filters will work. Also, as a bonus, delivering mail via LDA will correctly update user quotas -- the problem which resolved by itself :) Great :) >> >>> >>>> outgoing mail to folders, specific >>> >>> outgoing mail is smtp, with i.e imap copy to sent folder etc >>> if you want other folders your imap client should do it >>> >> >> So, I can invoke Sieve interpreter from SMTP server, or process it via dovecot-lda, like in fetcher case? > >in general ,i dont think so , there may be some workaround with server >bcc_copy and i.e plus adressing with sieve then for "sent" mail > Yes, this is a variant.

[Dovecot] Protocol logging - TLS vs SSL
by Charles Marcus 27 Feb '13

27 Feb '13

Hi all, Ok, I have: login_log_format_elements = user=<%u> method=%m rip=%r lport=%{lport} mpid=%e %c session=<%{session}> We only allow inbound IMAP, and only SSL on port 993. Looking at the logs, %c is obviously the encryption type, but... Why does it say 'TLS', when it technically (there is a difference after all) should say 'SSL'? Not a big deal, but it is just something I've been meaning to ask. -- Best regards, */Charles/*

[Dovecot] Can't access to shared mailbox
by Angel L. Mateo 27 Feb '13

27 Feb '13

Hello, I have a user sharing a folder to me (and other users). This has worked for me for a time. And it is still working for some users, but not for me. I'm using thunderbird (17.0.3, ubuntu 12.04 package). My server is dovecot 2.1.9 (it's the same since it works). The user sharing its mailbox is: $ sudo doveadm user t userdb: t home : /home/generica/02/001002 uid : 1002 he is sharing its mailbox "cron". This is its dovecot-acl: root@myotis31:/home/generica/02/001002/Maildir# cat dovecot-acl user=<other user> kxeilprwts user=<my user> kxeilprwts user=<other user> kxeilprwts user=<other user> kxeilprwts user=<other user> kxeilprwts user=<other user> kxeilprwts user=<other user> kxeilprwts I can subscribe to this folder: # sudo doveadm mailbox subscribe -u <myuser> shared.t.cron # sudo doveadm mailbox list -u <myuser> -s INBOX ... ... shared.t.cron but when I try to access to this folder through thunderbird (what I really do in TB is subscribe/unsubscribe to it, because it is not actually listed in the folder list), I get: Feb 26 13:35:03 myotis32 dovecot: imap(<myuser>): Error: Couldn't create namespace 'shared.' for user shared: userdb didn't return a home directory, but plugin setting quota used it (%h): dict:User quota::file:%h/Maildir/dovecot.quota With doveadm commands I can access to the shared folder from my user (not the user sharing): $ sudo doveadm search -u <myuser> mailbox shared.t.cron | wc -l 652 Other users can use this shared folder without any (apparent) problem. I have attached my doveconf -n. Any idea? -- Angel L.

[Dovecot] Special characters in dovecot.conf
by Antonio Casado Rodriguez 27 Feb '13

27 Feb '13

Hi all, I've configured "quota_exceeded_message" in dovecot 1.2, but I have two questions: - Can I use "CRLF" in it? I'd like have two messages: english and spanish. - If char character set in dovecot.conf is ASCII, How do I set special characters (spanish)?

[Dovecot] Master passwords and ACLs

Hello, Since I have activated acl plugin, master password is no longer working. I'm running dovecot 2.1.9 with master password and acl plugin (among others). I have attached my configuration. If I disable acl plugin, it works, but if I enabled it, dovecot fails. In the client, I get: amateo@joshua:~$ telnet myotis30.um.es 143 Trying 155.54.211.169... Connected to myotis30.um.es.

[Dovecot] "sent" and "accepted" missing mails
by Spyros Tsiolis 27 Feb '13

Hello all, OK, this most probably is not dovecot related. However, I have to start from somewhere. output of "dovecot -n" : # 1.2.16: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.17.4.el5 i686 CentOS release 5.5 (Final) ext3 base_dir: /var/run/dovecot/ log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot-info.log ssl_parameters_regenerate: 48 verbose_ssl: yes login_dir: /var/run/dovecot//login login_executable: /usr/local/dovecot/libexec/dovecot/imap-login login_greeting: * Dovecot ready * login_max_processes_count: 96 mail_location: maildir:/var/MailRoot/domains/%d/%n/Maildir mail_plugins: zlib auth default: verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /etc/dovecot/passwd passdb: driver: pam userdb: driver: static args: uid=vmail gid=vmail home=/home/vmail/%u userdb: driver: passwd User (really weird user) today tells me she is missing "sent" and "accepted" folders. She is running the latest version of Thunderbird on a windows XP pro 32-bit machine. My question is : Should I hunt something that is dovecot-related or is it MUA related ? And since I brought this up; Does anyone know if dovecot (v1.2.16) has any limits on user quota, message sizes and stuff like that ?

[Dovecot] Deleted / read mails show up as new on remote imap clients
by Andre Bischof 27 Feb '13

27 Feb '13

Hi, I've one problem: Mails, which I already read or deleted via my IMAP client (Thunderbird) on the same machine running the server (it runs behind DynDNS on my local machine, thanks to http://mein.homelinux.com/wiki/mailserver/) show up again if I connect via IMAP from other client computers, i.e. my notebook (Thunderbird again). As you can see from the config below I have /home/user/Maildir, not /var/mail - is that the problem? Or is that anything else, resulting in status from emails not being stored (or not being available remote) in the responding dovecot files (dovecot.index?). Some month ago I migrated from Cyrus, and if I remember correct I had some problems with migrating subscriptions, stati and so on (one had to use a special script, sorry, it's been some time now) ;-) So maybe s.th. went wrong which could be the source of this problem? Just guessing ... Ok, here's my config: root@linux:/lost+found# dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.5.0-25-generic x86_64 Ubuntu 12.10 auth_verbose = yes lda_mailbox_autosubscribe = yes mail_debug = yes mail_location = maildir:~/Maildir managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace inbox { inbox = yes list = yes location = prefix = separator = . type = private } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster@localhost protocols = imap pop3 sieve service auth { unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix mode = 0660 user = postfix } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 10 } protocol pop3 { mail_max_userip_connections = 10 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { deliver_log_format = msgid=%m: %$ mail_plugins = sieve sieve postmaster_address = postmaster quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r } root@linux:/lost+found# root@linux:/lost+found# dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.5.0-25-generic x86_64 Ubuntu 12.10 auth_verbose = yes lda_mailbox_autosubscribe = yes mail_debug = yes mail_location = maildir:~/Maildir managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave namespace inbox { inbox = yes list = yes location = prefix = separator = . type = private } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } postmaster_address = postmaster@localhost protocols = imap pop3 sieve service auth { unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix mode = 0660 user = postfix } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 10 } protocol pop3 { mail_max_userip_connections = 10 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { deliver_log_format = msgid=%m: %$ mail_plugins = sieve sieve postmaster_address = postmaster quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r } root@linux:/lost+found# If you need other info pls let me know.

[Dovecot] Converting a POP3 client to IMAP
by Kristen J. Webb 27 Feb '13

27 Feb '13

I have a dovecot 2.0 dovecot server set up for https/imap with spam, av, and some preliminary sieve filters in place. Our current email is outsourced and so we have used POP3 to keep all email on our systems for many years. I have run tests to move mail to the new imap server and that seems to work pretty well. However, we have lots of mail going back over a decade and used a lot of aliases that forwarded email to many users. I find the moving mail multiple times using Thunderbird results in multiple copies of the same email. Is there a best practice for moving mail such that we can take advantage of the hard link feature for all those older copies that are currently in POP3 files? It would also be nice to be able to auto file things. I don't see the sieve filters being activated when I copy mail in Thunderbird. Many thanks in advance for any guidance.

[Dovecot] Dict quota timeout error: Has anything changed in the latest versions?
by Alessio Cecchi 26 Feb '13

26 Feb '13

Hi, I'm using dict quota with mysql for track them via SQL query instead of read maildirsize file. Primary quota and enforcing is provided via userdb and is "maildir" type. Since dovecot 2.1.10-13 (but perhaps even before) when a new user log in via POP/IMAP or receive an email for the first time dovecot created the entry for the users in the table "quota" of dovecot database with quota usage and number of messages (before of this login/delivery the user has no entry in the quota table of dovecot DB). After the update to 2.1.14 when a new user login or receive an email for the first time dovecot was unable to create (immediately) the entry in quota table and in the log print these errors: Feb 12 11:03:49 master: Info: Dovecot v2.1.15 starting up (core dumps disabled) Feb 12 11:04:02 auth-worker(31421): Info: mysql(localhost): Connected to database vpopmail Feb 12 11:04:02 pop3-login: Info: Login: user=<alessio(a)domain.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=31422, secured, session=<eK4gJYTV1QB/AAAB> Feb 12 11:04:08 pop3(alessio(a)domain.com): Info: Disconnected: Logged out top=0/0, retr=0/0, del=0/9, size=18618 Feb 12 11:04:41 pop3-login: Info: Login: user=<alessio(a)domain.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=31424, secured, session=<D7F0J4TV1gB/AAAB> Feb 12 11:05:11 pop3(alessio(a)domain.com): Info: Disconnected: Logged out top=0/0, retr=0/0, del=1/9, size=18618 Feb 12 11:05:11 dict: Info: mysql(10.10.3.19): Connected to database dovecot [ here is when I "quit" from telnet session] Feb 12 11:05:41 pop3(alessio(a)domain.com): Error: read(/usr/local/dovecot-2.1/var/run/dovecot/dict) failed: Timeout after 30 seconds Feb 12 11:06:11 pop3(alessio(a)domain.com): Error: read(/usr/local/dovecot-2.1/var/run/dovecot/dict) failed: Timeout after 30 seconds Feb 12 11:06:41 pop3(alessio(a)domain.com): Error: read(/usr/local/dovecot-2.1/var/run/dovecot/dict) failed: Timeout after 30 seconds Feb 12 11:07:11 pop3(alessio(a)domain.com): Error: read(/usr/local/dovecot-2.1/var/run/dovecot/dict) failed: Timeout after 30 seconds Feb 12 11:07:41 pop3(alessio(a)domain.com): Error: read(/usr/local/dovecot-2.1/var/run/dovecot/dict) failed: Timeout after 30 seconds Feb 12 11:08:11 pop3(alessio(a)domain.com): Error: read(/usr/local/dovecot-2.1/var/run/dovecot/dict) failed: Timeout after 30 seconds Feb 12 11:08:41 pop3(alessio(a)domain.com): Error: read(/usr/local/dovecot-2.1/var/run/dovecot/dict) failed: Timeout after 30 seconds [ only now telnet close the session ] This is the telnet session: # telnet 0 110 Trying 0.0.0.0...

The fetcher is working on IMAP server side (not on user side, as usual). So, it is used to pull email from several POP3 servers to our IMAP server. The mail is stored in Maildir++ format. Yes, it is possible to configure fetcher to sort messages to folders by its own means, but I'd like to implement the mail sorting by means of Sieve filters. The user can easy configure filters in webmail interface, then it work with any IMAP client, because it is done on IMAP server side. So, if sieve is invoked by lda, then, probably, I could invoke dovecot-lda from wrapper script on each mail after it is fetched?

[Dovecot] Imap-login service count/limits
by Thomas Hummel 26 Feb '13

26 Feb '13

Hello Timo, I'm trying to configure dovecot-2.1.15 master correctly regarding imap-login limits. I want to use service_count=0 and I'm starting with something like this : #default_process_limit = 100 #default_client_limit = 1000 service imap-login { [...] service_count = 0 process_min_avail = 8 vsz_limit = 1024M } -> Does it make sense to set a process_limit if service_count = 0 ? why ? Doesn't service_count = 0 mean that no additionnal imap-login process would be created (except for process_min_avail) ? -> Does it make sense to set process_min_avail <> 0 if service_count = 0 ? why ? and if yes, what's the rule of thumb to find the correct value according to the number of connections estimation ? -> Assuming every client is configured to use STARTTLS and opens by default 5 imap connections, each client would consume 5 of the 1000 default_client_limit, right ? -> is 1024M too high for vsz_limit and may expose to memory leaks ? In other words, what limit should be raised to scale a lot a connections ? Thanks -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Groupe Exploitation et Infrastructure

Hi all Is it possible to configure Dovecot's sieve plugin to act on message arrival to folders, other than INBOX? I wish to move messages fetched by pop3 fetcher to special folder, or sort outgoing mail to folders, specific to their recipients. Thanhs in advance, WBR, valery

[Dovecot] Dovecot SASL: SCRAM-SHA-1 Authentication Fails
by Thomas Reim 26 Feb '13

26 Feb '13

Dear all, I use Dovecot SASL (2.1.15) on Ubuntu 12.04 for IMAP authentication and Postfix SASL authentication. I tried to setup SCRAM-SHA-1 as SASL mechanism. This works well on Dovecot's client side towards my OpenLDAP server (with libsasl-2), but fails on the server side (IMAP and SMTP). In the following, there's an extract from Dovecot's log, when using mutt as SMTP client: dovecot: auth: Debug: auth client connected (pid=0) dovecot: auth: Debug: client in: AUTH#0111#011 SCRAM-SHA-1#011 service=smtp#011 nologin#011 lip=192.168.0.65#011 rip=192.168.0.65#011 secured#011 resp=<hidden> dovecot: auth: scram-sha-1(?,192.168.0.65): authzid not supported dovecot: auth: Debug: client passdb out: FAIL#0111 postfix/smtpd[7621]: warning: markaurel.gas.de[192.168.0.65]: SASL SCRAM-SHA-1 authentication failed Here's the log, when using mutt as IMAP client: dovecot: auth: Debug: auth client connected (pid=23409) dovecot: auth: Debug: client in: AUTH#0111#011 SCRAM-SHA-1#011 service=imap#011 secured#011 session=<session ID>#011 lip=192.168.0.65#011 rip=192.168.0.65#011 lport=143#011 rport=36543#011 resp=<hidden> auth: scram-sha-1(?,192.168.0.65,<session ID>): authzid not supported auth: Debug: client passdb out: FAIL#0111 In the following is mutt's output: imap_authenticate: Trying method scram-sha-1 SASL local ip: 192.168.0.65;36543, remote ip:192.168.0.65;143 External SSF: 128 External authentication name: myname mutt_sasl_cb_authname: getting authname for mail.mydomain.local:143 mutt_sasl_cb_authname: getting user for mail.gas.de:143 mutt_sasl_cb_pass: getting password for myname@mail.mydomain.local:143 Authentifiziere (SCRAM-SHA-1)... 4> a0002 AUTHENTICATE SCRAM-SHA-1 <uuencoded string> 4< a0002 NO [AUTHENTICATIONFAILED] Authentication failed.

This 2nd try is succesful and mutt gets access to the imap/smtp service. Any hints, what's going wrong here?

[Dovecot] Dovecot auth works when tested with doveadm, but fails with Postfix
by Darren Pilgrim 26 Feb '13

26 Feb '13

I have three postfix 2.9.5 servers: chombo, rush, yoshi. Chombo relays to rush and yoshi for outbound email. Outbound relay requires SASL authentication. Rush and yoshi run Dovecot 2.1.12 servers with simple passwd-file backends. If I create a new password hash for chombo's user, houseloki, on either rush or yoshi: # doveadm pw -u houseloki -p <password> {CRAM-MD5}... Then I add that to rush and yoshi's passwd file: houseloki@_auth.bluerosetech.com:{CRAM-MD5}... Then `doveadm reload`, it works fine: # doveadm auth houseloki <password> passdb: houseloki auth succeeded extra fields: user=houseloki(a)_auth.bluerosetech.com So I add that username and password to the smtp_sasl_password_maps hash file on chombo, reload postfix, and then try to relay something from chombo, it fails with rush and yoshi logging warnings like: Feb 19 03:32:33 yoshi postfix/smtpd[75783]: warning: chombo.example.com[2001:db8::2]: SASL DIGEST-MD5 authentication failed: <really long string redacted> Rush and yoshi have other hashes in their passwd files, and if I configure chombo to use one of those, it works fine. Those hashes use digest-md5 and are at least a few years old. I tried that scheme instead of the default cram-md5, as well as several others, but none work. I've poured over the wiki and man pages, but can't find the problem. What am I missing? Why can I not generate new hashes correctly?

[Dovecot] 2.2beta2: LSUB broken
by Lutz Preßler 25 Feb '13

25 Feb '13

Hello, I have some problems with (listing) subscriptions on my test system running 2.2beta2 (compared with 2.1.15, configuration and Maildir content unchanged): With 2.1.15: 0 lsub "" "*" * LSUB () "." "INBOX.Trash" * LSUB () "." "INBOX.in2009" * LSUB () "." "INBOX.test" * LSUB () "." "INBOX.test.test2" * LSUB () "." "INBOX.in2010" * LSUB () "." "INBOX.in" * LSUB () "."

With 2.2beta2 (output of doveconf -n attached): 0 lsub "" "*" 0 OK Lsub completed. ... empty list. Same with "list (subscribed)".

[Dovecot] v2.2.rc1 released
by Timo Sirainen 25 Feb '13

25 Feb '13

http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc1.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.rc1.tar.gz.sig A few fixes since beta2. Also added tcp and tcps (=tcp+ssl) targets for dsync, where the destination needs to be a doveadm-server listener. I'm planning on releasing v2.2.0 in 1-2 weeks if no major problems are found. Please test and report any bugs found. BTW. I've also gone through basically all of my unread emails. If you haven't gotten a reply to something, ask again. Here's again all the biggest changes since v2.1: * When creating home directories, the permissions are copied from the parent directory if it has setgid-bit set. For full details, see http://wiki2.dovecot.org/SharedMailboxes/Permissions * "doveadm auth" command was renamed to "doveadm auth test" * IMAP: ID command now advertises server name as Dovecot by default. It was already trivial to guess this from command replies. * dovecot.index.cache files can be safely accessed only by v2.1.11+. Older versions may think they're corrupted and delete them. * LDA/LMTP: If saving a mail brings user from under quota to over quota, allow it based on quota_grace setting (default: 10% above quota limit). * pop3_lock_session=yes now uses a POP3-only dovecot-pop3-session.lock file instead of actually locking the mailbox (and causing IMAP/LDA/LMTP to wait for the POP3 session to close). * mail_shared_explicit_inbox setting's default switched to "no". * ssl_client_ca_dir setting replaced imapc_ssl_ca_dir and pop3c_ssl_ca_dir settings. + Implemented IMAP MOVE and BINARY extensions + Implemented IMAP CATENATE, URLAUTH and URLAUTH=BINARY extensions (by Stephan Bosch). + Implemented IMAP NOTIFY extension. Requires mailbox_list_index=yes to be enabled. + Redesigned and rewritten dsync. The new design makes the syncing faster, more reliable and more featureful. The new dsync protocol isn't backwards compatible with old dsync versions (but is designed to be forwards compatible with future versions). + All mailbox formats now support per-user message flags for shared mailboxes by using a private index. It can be enabled by adding :INDEXPVT=<path> to mail location. This should be used instead of :INDEX also for Maildir/mbox to improve performance. + Improved mailbox list indexes. They should be usable now, although still disabled by default. + Added LAYOUT=index. The mailbox directories are created using their GUIDs in the filesystem, while the actual GUID <-> name mapping exists only in the index. + LMTP proxy: Implemented XCLIENT extension for passing remote IP address through proxy.

[Dovecot] Bug when a duplicated file is found
by Angel L. Mateo 25 Feb '13

25 Feb '13

Hello, Last days we had to restore some mailboxes from backup. Our mailboxes are in maildir format and during restore, some duplicated files appeared. The situation is: * A user has messages in his new directory when the backup is made * In some moment after the backup is done, the user accesses to his mailbox, so the message is move to the cur directory. * We restore his mailbox directly to his maildir path, so the message is now at new directory too. When this happens, dovecot detect it and it renames one of the files. This is the reported log: Feb 13 23:08:05 myotis31 dovecot: imap(<user>): Warning: Fixed a duplicate: /home/alumnos/59/122559/Maildir/cur/1360169810.M670208P13643.myotis31,S=6282,W=6409:2, -> 1360793285.M721935P29136.myotis31 The problem with this is that we are using zlib plugin so messages are compressed. When the rename is done, the rename is to a name without the S=XXXX field (neither the W=XXX, although this field is less sensible), so the result is that user's can't access to any message after this one. I think than in this situation, rename one of the files is a good solution (although it provokes duplicate mails, but this an expected/acceptable situation after the restore), but the rename should maintain the S= and W= fields (and even other maildir flags). -- Angel L.

[Dovecot] SSL errors for just one client after updaing both dovecot and openssl
by Charles Marcus 25 Feb '13

25 Feb '13

Hi all, Ok, I have a strange problem after updating both dovecot and openssl... OpenSSL was 1.0.0j, now updated to 1.0.1c Dovecot was 2.1.13, now updated to 2.1.15 I'm getting a bunch of lines like the following: Feb 23 10:48:01 myhost dovecot: imap-login: Disconnected (no auth attempts in 29 secs): user=<>, rip=#.#.#.#, lport=993, TLS handshaking: SSL_accept() syscall failed: Connection reset by peer, session=<In+cO2bWngCthJz2> where only the session id (and number of seconds for no auth attempts) is different... This is happening for only the one client. All other clients - I've counted about 25 so far - are working fine. Anyone have any ideas? I can't believe it is a generic openssl problem, since it is only affecting the one client. I've contacted him and asked him to reboot any/all devices that connect to our mail to see if that helps... -- Best regards, */Charles/*

[Dovecot] understanding namespace configuration
by btb＠bitrate.net 25 Feb '13

25 Feb '13

i'm a little confused about namespace configuration. reading http://wiki2.dovecot.org/Namespaces , and looking at the examples, it seems that when a namespace is declared, you can either do "namespace { ..." or "namespace foo { ..." - i'm having trouble finding clarity on the significance of "foo" though. it would appear it's not required, but then what is its purpose? what does it mean? does it imply something? it's also unclear to me how to create the "default private namespace". i see that there are three types of namespaces, but the list of namespace settings doesn't seem to include a parameter to set the namespace type. what am i missing? it's also not quite clear how to denote a namespace as "default". from coming across this thread [ http://mailman2.u.washington.edu/pipermail/imap-protocol/2010-May/001077.ht… ] it would indicate in theory that a namespace is denoted as default by using an empty prefix - but i wasn't able to find corroboration of that in dovecot's documentation. thanks -ben

[Dovecot] dovecot-2.2: broken domain quota calculation
by Evgeny Basov 25 Feb '13

25 Feb '13

Hello. Used next version of dovecot: # dovecot --version 20130205 (03a0af22100d+) Quota configuration: plugin { quota = dict:Domain quota:%d:redis:host=127.0.0.1:prefix=domain/ quota_rule = *:storage=0 quota_rule2 = Trash:storage=+5%% quota2 = dict:User quota::redis:host=127.0.0.1:prefix=user/ quota2_rule = *:storage=0 quota2_rule2 = Trash:storage=+5%% } Problem: incorrect quota calculations. Dovecot gets size and messages count of all domain from last user in list. In 2.1 works fine. Steps to reproduce problem: 1. install dovecot 2. create over 50 users with e-mails 3. execute: doveadm quota recalc -A 4. execute: doveadm quota get -A 5. get count of all users message: sum in some application result of execution doveadm quota get -A | grep MESSAGE | grep 'User quota' | awk '{print $5}' (139443 messages) 6. get size of all users message: sum in some application result of execution doveadm quota get -A | grep STORAGE | grep 'User quota' | awk '{print $5}' (2304399 Kb) 7. look at some user user(a)example.org Domain quota STORAGE 82408 51200000 0 user(a)example.org Domain quota MESSAGE 1078 - 0 user(a)example.org User quota STORAGE 0 209715200 0 user(a)example.org User quota MESSAGE 0 - 0 and see 1078 messages and 82408 Kb in domain quota 8. look at last user in list z(a)example.org Domain quota STORAGE 82408 51200000 0 z(a)example.org Domain quota MESSAGE 1078 - 0 z(a)example.org User quota STORAGE 82408 209715200 0 z(a)example.org User quota MESSAGE 1078 - 0 and see matching values.

[Dovecot] Possible sort optimization (?)
by Michael M Slusarz 25 Feb '13

25 Feb '13

Maybe this is just noise... but I can reproduce this fairly reliably. Mailbox with 21,000+ messages This query: a UID SORT RETURN (ALL COUNT) (DATE) UTF-8 SUBJECT "foo" is always about 10 percent slower than this split query (I've done this 4-5 times, and the numbers are similar): a UID SEARCH RETURN (SAVE) CHARSET UTF-8 SUBJECT "foo" b UID SORT RETURN (ALL COUNT) (DATE) UTF-8 UID $ (The particular query I used matched 5 messages out of the 21,000+) My not-very-scientific benchmarking process: 1.) Stop dovecot process 2.) Delete all dovecot index files for that mailbox 3.) Flush linux paging cache (sync && echo 3 > /proc/sys/vm/drop_caches) 4.) Restart dovecot 5.) Access dovecot via command-line (PREAUTH) 6.) SELECT mailbox 7.) Issue command(s) Could be a potential area for performance improvement or could simply be lazy benchmarking. michael

[Dovecot] Problem with the command hooks api
by Tony 24 Feb '13

24 Feb '13

I have been trying to use the command hook api in an experimental plugin I have written. The hook is registered using the command_hook_register function, and for most commands my hook functions get called once as expected. But when the client uses one of the "UID" commands (e.g. "UID FETCH" ) the hook functions are executed twice. I am using dovecot version 2.1.12. Am I correct in thinking this is a bug? If I am wrong and this is the intended behaviour, how should I detect whether the hook function call is the first or second for a client's command (in particular for the 'post command' hook)? Assuming it is a bug, I modified the code in the command_exec function to stop the second hook call, a patch for this is below. This appears to apply to later dovecot releases as well. I am happy for this code to be included in future releases of dovecot.

[Dovecot] LMTP logging
by Peter Rindfuss 24 Feb '13

24 Feb '13

Hi, Is there a way (in Dovecot 2.1.14) to sent LMTP log entries and IMAP log entries to different files? I know I could achieve this with syslog-ng, but as LDA has a log file of its own, I am wondering if this is possible with LMTP as well. I apologize if I missed something in the wiki. Thanks, Peter

The fact that the same certificate works for other clients, and also for TLS on Thunderbird seem to suggest Thunderbird is fumbling it. But maybe you can try the command diagnostic from the command line "openssl s_client -connect yourserver:993 ..." or use one of the online certificate checkers to get some useful diagnostics. > TLS: SSL_read() failed: error:14094418:SSL > routines:SSL3_READ_BYTES:tlsv1 alert unknown ca This error entry pops up in my logs once in a while. I think the error might be misleading since the error message happen in the middle of a long sequence of successful connections. Also check that the client is actually using the right security mode (not TLS or clear), perhaps by doing a network snoop. Joseph Tam <jtam.home(a)gmail.com>

I use 'doveadm user' in some scripts and the exit codes are fine for my purposes. During tests it transpired that Dovecot 2.1 would give an error message when querying for non-existent users. Dovecot 2.2 just exits without a word. Not sure this is intended behaviour: $ doveadm user foo $ echo $? 67 $ id foo id: foo: No such user Regards Thomas

22 Feb '13

hi, i'm using dovecot 1.2.15 with self signed certificates using starttls on ports 110/143 works ok with thunderbird 10.0.12 (and i guess most other clients) using imaps on port 993 works with outlook 2002. with thunderbird 10.0.12 i can't connect to port 993 and get errors in the logs like TLS: SSL_read() failed: error:14094412:SSL routines:SSL3_READ_BYTES:sslv3 alert bad certificate (certificate generated by dovecot mkcert.sh) or TLS: SSL_read() failed: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca (certificate generated by own openssl cmdline) i know that a lot of information is missing, but since this looks like a more general problem i dare to ask for help before posting more config details thx matthias

[Dovecot] pop3_lock_session and mdbox format
by Ewald Dieterich 22 Feb '13

22 Feb '13

Setting "pop3_lock_session = yes" in the configuration has no effect when I use Dovecot 2.1.13 with the mdbox format. A second POP3 connection to the same mailbox is still allowed. Grepping for MAILBOX_FLAG_KEEP_LOCKED in the source code shows that POP3 session locking only works for the Maildir and mbox formats. Is it possible to enable it for the mdbox format, as well? Ewald

Hi Is there a way to set environment variables for the auth process? All I found for now is to replace it by a shell script that sets variables and then launch the real auth, but I wonder if there is a better way. -- Emmanuel Dreyfus manu(a)netbsd.org

Hi NetBSD 6.0 introduced a new improved quota subsystem and an unified API (libquota) to handle the new and old quota implementation. dovecot is unable to use the new quota implementation right now, and will even fail to build with the old quota API on NetBSD 6.0: Here are dovecot patches to support NetBSD libquota: http://ftp.espci.fr/shadow/manu/dovecot-libquota.tgz -- Emmanuel Dreyfus http://hcpnet.free.fr/pubz manu(a)netbsd.org

[Dovecot] Trouble with expire plugin
by Gedalya 22 Feb '13

22 Feb '13

Hi all, Maybe someone here can help me with this problem, not sure if this is a configuration issue or an actual bug. my daily cron job says: #!/bin/sh doveadm expunge -A mailbox Junk savedbefore 14d doveadm expunge -A mailbox Trash savedbefore 30d doveadm expunge -A mailbox "Trash.*" savedbefore 30d But it hasn't been deleting any messages in a long time, I'm not sure when it stopped working. I've also noticed that it does delete matching rows in the expires database (expire_stamp < savedbefore days). Furthermore, rows are deleted even when running doveadm search, and regardless of the mailbox column, i.e. even when != the mailbox name being searched! Anyway why should doveadm search delete rows in the expires database? The database is mysql. ---- dovecot -n ---- # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-0.bpo.3-amd64 x86_64 Debian 6.0.6 auth_default_realm = xxxxxxx.com auth_mechanisms = plain login cram-md5 auth_verbose = yes auth_verbose_passwords = plain default_client_limit = 8096 dict { expire = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } disable_plaintext_auth = no mail_gid = vmail mail_plugins = quota expire listescape mail_uid = vmail managesieve_sieve_capability = fileinto envelope encoded-character subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables mailbox date ihave namespace { inbox = yes location = prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { antispam_backend = pipe antispam_pipe_program = /usr/bin/ssh antispam_pipe_program_args = -l;spamd;-i;/etc/dovecot/sareport.key;mx1.xxxxxxx.com antispam_pipe_program_notspam_arg = revoke antispam_pipe_program_spam_arg = report antispam_pipe_tmpdir = /tmp antispam_spam = Junk antispam_trash_pattern_ignorecase = trash;Deleted * autocreate = Trash autocreate2 = Junk autocreate3 = Drafts autocreate4 = Sent autosubscribe = Trash autosubscribe2 = Junk autosubscribe3 = Drafts autosubscribe4 = Sent expire = Trash expire2 = Trash.* expire3 = Junk expire_dict = proxy::expire quota = dict:user::proxy::quota quota_rule = *:storage=2G quota_rule2 = Trash:storage=+250M quota_rule3 = Junk:ignore quota_warning = storage=99%% quota-warning 99 %u quota_warning2 = storage=95%% quota-warning 95 %u sieve = ~/.dovecot.sieve sieve_before = /var/local/lib/dovecot/sieve/global/fileinto-spam.sieve sieve_dir = ~/sieve sieve_extensions = -vacation -body -reject -enotify -environment -virustest -spamtest sieve_max_actions = 32 sieve_max_redirects = 4 sieve_max_script_size = 10K sieve_quota_max_scripts = 10 } postmaster_address = postmaster(a)xxxxxxx.com protocols = imap pop3 lmtp sieve service auth-worker { user = $default_internal_user } service auth { client_limit = 20480 unix_listener auth-userdb { group = root mode = 0600 user = vmail } } service dict { unix_listener dict { mode = 0600 user = vmail } } service imap-login { process_min_avail = 4 service_count = 0 vsz_limit = 128 M } service imap { process_limit = 10240 } service lmtp { inet_listener lmtp { address = 0.0.0.0 port = 7025 } } service managesieve-login { inet_listener sieve { port = 4190 } service_count = 0 vsz_limit = 128 M } service pop3-login { process_min_avail = 4 service_count = 0 vsz_limit = 128 M } service pop3 { process_limit = 4096 } service quota-warning { executable = script /usr/local/bin/quota-warning unix_listener quota-warning { user = vmail } user = vmail } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } verbose_proctitle = yes protocol lmtp { mail_plugins = quota expire listescape sieve } protocol lda { mail_plugins = quota expire listescape sieve } protocol imap { mail_max_userip_connections = 25 mail_plugins = quota expire listescape autocreate imap_quota antispam ssl_cert = </etc/dovecot/imap.xxxxxxx.com.crt ssl_key = </etc/dovecot/imap.xxxxxxx.com.key } protocol sieve { mail_max_userip_connections = 10 } protocol pop3 { mail_max_userip_connections = 10 mail_plugins = quota expire listescape pop3_fast_size_lookups = yes pop3_lock_session = no pop3_no_flag_updates = yes pop3_reuse_xuidl = yes pop3_save_uidl = no pop3_uidl_format = %08Xu%08Xv ssl_cert = </etc/dovecot/pop.xxxxxxx.com.crt ssl_key = </etc/dovecot/pop.xxxxxxx.com.key } in dovecot-sql.conf.ext I have: iterate_query = SELECT userid as user, domain FROM email where deleted=0 ---- dovecot-dict-sql.conf.ext ---- connect = host=localhost dbname=email user=email map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } map { pattern = shared/expire/$user/$mailbox table = expires value_field = expire_stamp fields { username = $user mailbox = $mailbox } }

FTS indexing of binary attachments is broken in dovecot-2.1.15: the binary data which fts_build_mail_real() sends to fts_build_body_block() (which sends it to fts_backend_update_build_more()) is garbled.

[Dovecot] Userdb passwd and 'nologin' users
by Ben Morrow 22 Feb '13

22 Feb '13

I am running Dovecot with system users (userdb passwd), but some of those users don't have shell accounts on the IMAP server so their shell on that machine is set to /usr/sbin/nologin. Currently I am using maildirs and this is not a problem, but I am in the process of switching to dbox which means I will need a cronjob running 'doveadm purge -A'. During testing I found that those users with a 'nologin' shell are not included in the list returned by the userdb iterator, and that the iterator doesn't honour the first/last_valid_uid settings. This inconsistency seems undesirable, so the attached patch - makes lookup perform the same checks as iteration, - makes the 'nologin' check configurable, - adds a new optional check that the user owns their home directory. The last check was the one performed by qmail, and seems to me to be a more reliable 'is this a real user' check than a nologin shell. If this patch is applied, the release notes for the next release should probably mention that system users with a 'nologin' shell will no longer be allowed to log in to IMAP until the 'auth_check_nologin' setting is changed from true to false. Also, there seem to be two first/last_valid_uid settings: first_valid_uid itself, which is honoured by the storage subsystem, and auth_first_valid_uid, which is honoured by the 'passwd' userdb. Is this intentional? Ben

Dovecot tries to parse messages in the mailbox, and can't correctly determine where the message header ends. So, it thinks that the message header is big, and passes very big data to Solr. When trying to index it, Solr exhausts the available memory (though, I have 8 Gb of RAM on my machine, and java eats more than 2 Gb when indexing). Then connections to Solr get closed, and maxfd is invalid, hence the assertion is failed. Note also the following error ========================================================== SEVERE: org.apache.solr.common.SolrException: undefined field text ========================================================== before an out of memory error. I also tried to tweak the decode2text.sh script to ignore all attachments bigger than 1 Mb (just test if the file is bigger than 1 Mb, and if so, return "1"). This won't help. As I understood, this is because of big header, so attachments doesn't matter. I separated the set of messages which cause this error (by their UID's). So, I can give them as a testcase, the size of them all in archive is about 40 Mb. The error can be reproduced if put all these messages into an empty mailbox, and do reindexing, via IMAP search, or via "doveadm index -u ". I use Dovecot version 2.1.13.

[Dovecot] Errors with doveadm when using checkpassword
by Andy Dills 22 Feb '13

22 Feb '13

We have a checkpassword authentication with mysql pre-fetch for the userdb lookups. When trying to do: doveadm search -u andytest(a)xecu.net mailbox Trash DELETED I get: doveadm(andytest(a)xecu.net): Error: user andytest(a)xecu.net: Auth PASS lookup failed doveadm(andytest(a)xecu.net): Fatal: /var/run/dovecot/auth-userdb: passdb lookup failed (to see if user is proxied, because doveadm_proxy_port is set) And I see this in the logs: Feb 4 12:02:04 mail-out01 dovecot: auth: Error: userdb-checkpassword(andytest(a)xecu.net): Child 12591 exited with status 1 I'm not surprised the checkpassword lookup is failing; the password isn't being supplied. Shouldn't it just be doing the prefetch lookup instead, like the lmtp service? Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---

[Dovecot] Connection leak in sqlpool for ACL Dict Postgres in v2.1.15 (14907:b96df105ec55) and v2.2.beta1 (15857:07dfd4391d22)
by Steffen Kaiser 22 Feb '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm using a postgres dict for ACL, when when use deleteacl or setacl I get a "not connected" error and (v2.2) Panic: file driver-pgsql.c: line 84 (driver_pgsql_set_state): assertion failed: (state == SQL_DB_STATE_BUSY || db->cur_result == NULL) and a rawdump eventually. You can trigger the error with the "dict" socket easily: while true; do ( echo -en "H2\t0\t0\t\tacl\nI1\tshared/shared-boxes/\n" sleep 1 ) | socat - unix:/var/run/dovecot2.2/dict done I interprete H2-I1..-bang.log.gz (logged with v2.1) so, that each time the ACL dict is iterated, driver_sqlpool_query_s() is executed two times, once for user_shares and once for anyone_shares. I guess that the user_shares one is never finished, so that the sqlpool keeps that slot in "busy" state until timeout. The information about the slots of the log lines 0x9886d0 1. state=3 to_recon=(nil) ready=0 |driver_sqlpool_query_s end is generated by: conns = array_get(&db->all_connections, &count); for (i = 0; i < count; i++) { struct sql_db *conndb = conns[i].db; i_info("SKA: POOL: [%u] %p %u. state=%u to_recon=%p ready=%u |%s", getpid(), db, i, conndb->state, conndb->to_reconnect, SQL_DB_IS_READY(conndb)? 1: 0, msg); } msg is the function, where that log function is called from, e.g. at the end of driver_sqlpool_query_s() in this case, which is right before the return. When the user_shares query ends in driver_sqlpool_query_s(), one additional slot of the sqlpool is in state 3, at the end of driver_sqlpool_query_s() of the anyone_shares query there are two slots in state 3. When the next I1 command triggers the next iteration, there is one slot still in state 3 at the start of driver_sqlpool_query_s(), which seems to be the slot used for the user_shares query of the previous I1 command. It looks like that the user_shares query has not been "finished" correctly and is left open. The assert() panics, because db->cur_result is != NULL. When all slots in the pool have been used up, the sqlpool enters "not connected" state and all dict connections fail with this error now. Then the assert causes the dict to die eventually, I guess, because of a timeout. The quota dict seems to not trigger that behaviour, because it uses the "L" (lookup) command, but when the sqlpool is in "not connected" state, these commands fail, too. Attached you'll find the config and log file.

[Dovecot] Dovecot 2.2. proxy_maybe and twice SSL connections
by Evgeny Basov 22 Feb '13

22 Feb '13

Hello. 1. I have two identically hosts 2. I have set up replication between two hosts 3. I have 'Y' AS proxy_maybe in password_query. 4. password_query returns one of this one hosts 5. I set this parameters in dovecot config: disable_plaintext_auth = yes ssl = yes auth_mechanisms = plain login for enforce use encrypted connections by client programs. When the client connects to host imap2 directly, connection is encrypted, it is good. | client | ---- (1) ----> |imap2 (proxy_maybe='y', host = imap2)| And when the client connects to another host, I have (1) and (2) connections are encrypted | client | ---- (1) ----> |imap1 (proxy_maybe='y', host = imap2)| ---- (2) ----> |imap2| but need only (1). How do I have desired behavior? Is it possible?

[Dovecot] Using different auth_default_realm on multiple sockets with postfix. Is it possible?
by Gábor Lénárt 22 Feb '13

22 Feb '13

Hi, I have more postfix smtpd instances (via master.cf) listening on different ports, and the FW passes the inbound mail submit connections to the right port. The problem: it seems postfix is not able to append "default realm" and I need to set different values for the instances. As far as I see, it's not possible as postfix only passes the base64 encoded string from the user to the dovecot auth service (as I'm using dovecot for sasl authentication). We're talking about PLAIN and LOGIN methods. In the other hand, dovecot is happily append "realm" with auth_default_realm. It works (which does not with postfix) but again: I need more defaults. I wouldn't like to run multiple instances of dovecot (just for having a single setting be different), so I've tried similar solutions: service auth { unix_listener /var/spool/postfix/private/auth-dom1 { group = postfix mode = 0660 user = postfix } auth_default_realm = domain1.com } And the same for /var/spool/postfix/private/auth-dom2 with domain2.com. I thought then I could use postfix's master.cf to give different auth socket (like /var/spool/postfix/private/auth-dom1 and auth-dom2) with smtpd_sasl_path postfix parameter. However it seems dovecot finds auth_default_realm invalid unless it's used in the global scope of the configuration. It's dovecot 2.0.19 (in Ubuntu 12.04 LTS). Is it possible at all, what I would like to do? Maybe with newer dovecot, or can you suggest me some other solution? Any feedback is welcomed and thanked. Thanks, - Gábor

[Dovecot] Errors after enable vnd.dovecot.duplicate

Hi, on dovecot 2.1.14 and pigeonhole-0.3.3 after creating a default.sieve like this: require ["vnd.dovecot.duplicate", "fileinto", "mailbox"]; if duplicate { fileinto "Trash"; } I have two strange errors, one is many of this error in lda.log: Feb 19 14:43:17 lda(info(a)domain.com): Error: file_dotlock_create(/home/vpopmail/domains/domain.com/info/.dovecot.lda-dup… failed: Resource temporarily unavailable Feb 19 14:43:43 lda(info(a)domain.com): Error: file_dotlock_create(/home/vpopmail/domains/domain.com/info/.dovecot.lda-dup… failed: Resource temporarily unavailable Feb 19 14:44:29 lda(info(a)domain.com): Error: rename(/home/vpopmail/domains/domain.com/info/.dovecot.lda-dupes.lock, /home/vpopmail/domains/domain.com/info/.dovecot.lda-dupes) failed: No such file or directory Feb 19 14:44:29 lda(info(a)domain.com): Error: file_dotlock_replace(/home/vpopmail/domains/domain.com/info/.dovecot.lda-du… failed: No such file or directory Note that my mailboxes are store on NFS.

[Dovecot] Full-text search
by Valery V. Sedletski 22 Feb '13

22 Feb '13

Hi all I discovered that the full-text search (fts) plugin can work without SQUAT/LUCENE/SOLR backend. I.e., Dovecot creates separate indexes for header search in files dovecot.index and dovecot.index.cache. Even, the search by headers is fast enough, and can search for phrases. Also, it seems that this buillt-in search is faster than Solr-based search. But if I enable the Solr backend (fts_solr), then the FTS generic plugin built-in search becomes disabled. But, Solr-based Full-text search is faster if search inside message bodies. Also, it appears that the built-in search inside message bodies works too, but very slow (it seems that is because it is dumb file-based search and does not use indexes at all) So, my question is: is it possible to combine the built-in search with Solr or Lucene plugin-based search so that the first one searches by headers, and the second one works by bodies? This could make the advantages of both search methods combined. WBR, valery

[Dovecot] Problem with managesieve proxy
by Lance A. Brown 22 Feb '13

22 Feb '13

Hi folks, I'm setting up a new dovecot email service and have a proxy server running in front of it to facilitate migrating users from my very old UW-IMAP-based mail server to the new one. I have a mysql proxy table that directs inbound IMAP and LMTP connections to the correct server, works great. Managesieve connections are not working through the proxy using either with the sieverules plugin for RoundCube or the Sieve plugin for Thunderbird. If I point them directly at the actual dovecot server everything works fine, so I must have something wrong in my proxy setup. This is what I get in the maillogs when I try to connect to the managesieve proxy: PROXY machine: Feb 21 16:16:38 sortie dovecot: managesieve-login: Error: proxy: Remote x.y.z.110:4190 disconnected: Connection closed (state=0, duration=0s): user=<brown>, method=PLAIN, rip=x.y.z.83, lip=x.y.z.109, TLS, session=<0jUal0LWswCYAxZT> Feb 21 16:16:38 sortie dovecot: managesieve-login: Disconnected (internal failure, 1 succesful auths): user=<brown>, method=PLAIN, rip=x.y.z.83, lip=x.y.z.109, TLS, session=<0jUal0LWswCYAxZT> SERVER machine: Feb 21 16:16:38 postie dovecot: managesieve-login: Disconnected: Too many invalid commands.

[Dovecot] Dovecot list archives not updating

22 Feb '13

The February archive indexes of this list haven't been updating since Feb 8. The text file at <http://dovecot.org/pipermail/dovecot/2013-February.txt> appears to be up to date with all posts, but the index pages at <http://dovecot.org/pipermail/dovecot/2013-February/thread.html>, <http://dovecot.org/pipermail/dovecot/2013-February/subject.html>, <http://dovecot.org/pipermail/dovecot/2013-February/author.html> and <http://dovecot.org/pipermail/dovecot/2013-February/date.html> have no posts after the one at <http://dovecot.org/pipermail/dovecot/2013-February/071213.html> from Fri Feb 8 16:31:49 EET 2013. Subsequent posts appear to not have individual HTML pages either as URLs <http://dovecot.org/pipermail/dovecot/2013-February/071214.html> and <http://dovecot.org/pipermail/dovecot/2013-February/071215.html> return 404 errors. I suspect there is a permissions issue starting soon after Fri Feb 8 16:31:49 EET 2013 and that Mailman's error log has lots of tracebacks from this. If that is the case, the messages were probably all shunted and running Mailman's bin/unshunt after fixing the underlying issue and also making sure that any messages older than Fri Feb 8 16:31:49 EET 2013 in Mailman's 'shunt' queue that should not also be reprocessed are removed. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

[Dovecot] Public folders and dsync replication Dovecot v2.1.7
by Steve Brown 21 Feb '13

21 Feb '13

Dear all I have a few public folders setup and working fine, and one such public folder is 'Public/General'. I'm trying to sort dsync replication out to another server and notice that the system log is full of error messages similar to: dovecot: doveadm: Error: dsync-remote(username: Error: Can't update subscription Pu blic/General: Invalid mailbox name The replication setup is basically as per the v2 wiki. It seems that when a mail client subscribes to a public folder, the folder name is put into '~/Maildir/subscriptions' and this seems to be the cause of the error during replication. The mails are not synchronised to the other server. Public namespace is: namespace { type = public separator = / prefix = Public/ location = maildir:/home/shared/public subscriptions = no list = yes } Hopefully somebody can send the clue bus over?

[Dovecot] Dovecot LDA LDAP lookups on samba4 server ends very often in timeouts
by marco＠carcano.ch 20 Feb '13

20 Feb '13

I hope that someone will be so kind to help me into solving this really strange thing (don't know if it is a bug or not) I have a samba4 server and want to use postfix+dovecot - dovecot version is 2.0.11 as for the postfix side everything is OK (all the LDAP lookups works without any error, tested also manually with postmap -q) the real pain is with dovecot deliver: it seems that sometimes lda tries to lookup to the LDPA (samba 4) server, got a reply, an then report(after 2 minutes) a lookup timeout error the really strange thing is that (very seldom) lda works, but most of the times I got the timeout error. The strange thing is that if I use ldapsearch I never got timeout neither late replies, and even postfix performs its lookups without any issue it seems something related to lda itself (I do not know if I have a wrong configuration, but I think this is not a configuration issue, otherwise it should not work at all) here are the information logged when it does not work - after this log you will find the one when I got the failure (if needed I can provide a .pcap file too) (trailing and leading spaces of AT charcater has been added by me) ############################## FAULTY DELIVER LOG

[Dovecot] Changin password in LDAP

We are using now dovecot 2.0.21 with open-ldap, but this situations has already taken a quite long time.

[Dovecot] 1.x with mbox files to 2.x with mdbox, I think?
by Ken A 20 Feb '13

20 Feb '13

Hi, I have a couple questions about migrating from 1.x to 2.x I'm needing to support larger mailbox sizes and mdbox seems like the right format to use to get larger size boxes and maintain, or possibly even increase speed. Is that correct? Am I correct that the best way to accomplish this migration is to copy the mboxes over to the new server and then use dsync to convert them to mdbox? Thanks for your thoughts!

[Dovecot] Dovecot-2.1.14 - pop3 processes always hangs forever - another follow-up
by Axel Luttgens 19 Feb '13

19 Feb '13

Hello, With the same basic configs as in my previous messages, I tried with the maildir format instead of the mbox format. That is, in both cases ("virtual" uids/gids vs a single "real" uid/gid), doveconf -n shows: mail_location = maildir:~/maildir instead of: mail_location = mbox:~/mboxes:INBOX=~/mboxes/inbox Here too, with "virtual" uids/gids, connections thru pop hang forever, while imap connections behave flawlessly. And with a single "real" uid/gid, connections thru both pop and imap behave as expected. As a result, it could be inferred that the problems I am encountering with pop connections do not depend on the mailbox format in use, and that they are entirely related to "virtual" uids/gids. To recap: with this very basic config # 2.1.14: /_ETC/dovecot/dovecot.conf # OS: Darwin 12.2.1 x86_64 auth_verbose = yes disable_plaintext_auth = no mail_debug = yes mail_location = mbox:~/mboxes:INBOX=~/mboxes/inbox passdb { args = /_ETC/dovecot/db.conf driver = sql } ssl = no userdb { driver = prefetch } a pop connection hangs forever after the pass command $ telnet 127.0.0.1 110 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Dovecot ready. user user2 +OK pass pass2 and the log shows (here, when the user connects for the first time) dovecot[2997]: pop3-login: Login: user=<user2>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=3113, secured, session=<GTOlMjfV3gB/AAAB> dovecot[2997]: pop3(user2): Debug: Effective uid=100003, gid=100003, home=/_Data/Mailstores/100003 dovecot[2997]: pop3(user2): Debug: Home dir not found: /_Data/Mailstores/100003 dovecot[2997]: pop3(user2): Debug: fs: root=/_Data/Mailstores/100003/mboxes, index=, control=, inbox=/_Data/Mailstores/100003/mboxes/inbox, alt= dovecot[2997]: pop3(user2): Debug: Namespace : /_Data/Mailstores/100003/mboxes doesn't exist yet, using default permissions dovecot[2997]: pop3(user2): Debug: Namespace : Using permissions from /_Data/Mailstores/100003/mboxes: mode=0700 gid=-1 dovecot[2997]: pop3(user2): Debug: Namespace : /_Data/Mailstores/100003/mboxes/inbox doesn't exist yet, using default permissions dovecot[2997]: pop3(user2): Debug: Namespace : Using permissions from /_Data/Mailstores/100003/mboxes: mode=0700 gid=-1 dovecot[2997]: pop3(user2): Debug: Namespace : /_Data/Mailstores/100003/mboxes/inbox doesn't exist yet, using default permissions dovecot[2997]: pop3(user2): Debug: Namespace : Using permissions from /_Data/Mailstores/100003/mboxes: mode=0700 gid=-1 With exactly the same config, imap connections are fully functional. Does someone have an explanation? TIA, Axel

[Dovecot] Defer emails until the user is ready to deal with them (snooze button / bring-forward file / bring-up file for emails)
by Chris Laif 19 Feb '13

19 Feb '13

Hi, I would like to add a feature to my email-client (Thunderbird) which stops emails from showing up until a specific time (e.g. having buttons for: show again this evening, tomorrow, next week, next month ...). As far as I've learned this is not possible with IMAP: - storing the 'do-not-show-until-time' within a custom header-field requires down- and uploading of the whole email and therefore causes problems especially with large emails - IMAP keywords are limited are limited in quantity and can not be compared with datetime functions Any suggestions will be greatly appreciated! Chris

[Dovecot] Get rid of inotify in 2.1.15
by Martin Rabl 19 Feb '13

19 Feb '13

Hi, after update to Dovecot 2.1.5 (Ubuntu 12.04, dovecot from https://launchpad.net/~kokelnet/+archive/dovecot21) we are getting a huge ;-) bunch of log entries about " imap(USERNAME): Warning: Inotify instance limit for user 5000 (UID vmail)". At last I did an echo 512 > /proc/sys/fs/inotify/max_user_instances but the logentries did appear again after some minutes. Maybe you have a hint for me? Thank you!

[Dovecot] statistics on proxy ???
by Marco Giunta 19 Feb '13

19 Feb '13

Hi at all, could I have imap statistics on my dovecot proxy server ?? Here my config: # 2.1.13: /etc/dovecot/dovecot.conf ... mail_plugins = stats ... plugin { ... stats_refresh = 30 secs stats_track_cmds = yes } ... service stats { fifo_listener stats-mail { mode = 0666 } } ... protocol imap { ... mail_plugins = stats imap_stats } File '/var/run/dovecot/stats' is always 0 byte: # ls -la /var/run/dovecot/stats srw-------. 1 root root 0 Feb 18 14:24 /var/run/dovecot/stats and 'dovecotadm' say always: # doveadm stats dump session doveadm(root): Info: no statistics available Is there something wrong in my config, or stats are not available on proxy ??? Cheers, Marco

[Dovecot] Private message flags in shared mailboxes
by Timo Sirainen 19 Feb '13

19 Feb '13

I'm wondering a bit how these should work. Comments welcome. In v2.2 the recommended way to enable private flags for shared mailboxes is to create private indexes with :INDEXPVT=<path>. This creates dovecot.index.pvt[.log] files which only contain message UIDs and flags. The indexes are updated somewhat lazily by updating them whenever user has the shared mailbox opened and it gets synced. 1. What would be a good place to configure which flags are shared and which are private? Currently it forces \Seen flag to be private and others not. With Maildir I used to have the idea of configuring these in dovecot-shared file, but that's a rather annoying extra file. Then again it could be cached into dovecot.index. Another possibility would be in dovecot-acl file, but public mailboxes might be enabled without ACL plugin. Mailbox attributes (for URLAUTH and for future METADATA) also exist in v2.2, but they require configuring a dict for them, which isn't very efficient either to read every time a mailbox is accessed. Mailbox's admin user should be able to do this somehow via IMAP protocol also. METADATA would pretty much be required for that I guess. 2. Private flags aren't currently inherited from the primary (shared) flags. With user-shared mailboxes this is good, because the owner doesn't have private indexes for the mailboxes, so when owner reads a mail it gets a \Seen flag in the primary index. If that mailbox was shared to someone else, the \Seen flag shouldn't be set. But this also means that for truly shared (public) mailboxes that have no owner you can't set initial flags with Sieve's addflag command (e.g. \Seen flag to high-scored mails in Spam). I guess it could be possible to change this so that the inheritance is done for public namespaces but not for shared namespaces, but is that really a good idea either?.. 3. Currently COPY/APPEND ignore any private flags (which also means dsync won't set them always). Fixing this would require remembering these flags, committing the save to primary index, syncing the private index to get the new mails added there, then updating their flags (or doing it directly at sync stage with some kludging code). To avoid race conditions the private index would need to be locked before committing the save. I guess this is doable.. 4. Private keywords aren't supported. I guess not much worse than system flags, but more code complexity. Wonder if anyone would care about them.

[Dovecot] proxy imaps
by Antonio Casado Rodriguez 16 Feb '13

Hi all, I had a imaps dovecot server working normal. I wanted to isolate the Internet connection by placing a proxy imap(Intranet connections still connect directly to the imap server). Yesterday I set up oneproxy imaps dovecot and thereafter, imap dovecot logs on errors: imap-login: Error: OpenSSL malloc() failed. You may need to increase login_process_size Need dovecot more memory with imap proxy connections than direct connections?

[Dovecot] dovecot-2.2: dsync to imapc not working
by Evgeny Basov 16 Feb '13

16 Feb '13

Hello. I have dovecot installation # dovecot --version 20130205 (03a0af22100d+) built with imapc backend. I'm tried to sync mailboxes from another server after clean mail directory localy: # dsync -v -o imapc_user="user(a)example.org" -o imapc_password="pass" -o imapc_host=imap.example.org -o imapc_features=rfc822.size -o mailbox_list_index=no backup -R -f -u "user(a)example.org" imapc: and get this message dsync(user(a)example.org): Error: Exporting mailbox INBOX failed: Backend doesn't support GUIDs, sync with header hashes instead Repeated command returns this one message: dsync(user(a)example.org): Error: Mailbox INBOX sync: mailbox_delete failed: INBOX can't be deleted. What wrong with this build? Maybe there is another way to do it? For example create backup in local temporary directory and synchronize this one and working storage.

[Dovecot] accumulating orphaned processes
by Jeff Gustafson 16 Feb '13

16 Feb '13

I'm getting orphaned processes on our mail servers. Some machines has processes hanging around from a week ago. I'm running the current stable of dovecot 2.1.15, but the problem has been happening for a while now. I thought it would be good to report the issue. I ran an strace on one of them and this is the output: Process 21370 attached - interrupt to quit open("/var/run/dovecot/stats-mail", O_WRONLY) = 7 write(7, "DISCONNECT\ta09ade0350d81d517a530"..., 44) = 44 munmap(0x7f1ad8a8d000, 266240) = 0 close(13) = 0 close(12) = 0 epoll_ctl(9, EPOLL_CTL_DEL, 11, {0, {u32=17384128, u64=17384128}}) = 0 close(11) = 0 close(7) = 0 munmap(0x7f1ada5d6000, 2106272) = 0 munmap(0x7f1ada7d9000, 2161360) = 0 munmap(0x7f1ada3cf000, 2124136) = 0 munmap(0x323c800000, 2162768) = 0 munmap(0x7f1ad9fc8000, 2102976) = 0 munmap(0x7f1ada1ca000, 2114728) = 0 epoll_ctl(9, EPOLL_CTL_DEL, 4, {0, {u32=17319120, u64=17319120}}) = 0 close(4) = 0 close(8) = 0 close(9) = 0 exit_group(0) = ?

[Dovecot] Requested xxxx scheme, but we have a NULL password after upgrade
by PhilQ 15 Feb '13

15 Feb '13

I'm having an issue I can't seem to work around after upgrading from Dovecot 1.0.7 to 1.2.17. After getting Dovecot 1.07 working on CentOS 5.9, I decided that it might be wise to upgrade to a later version, so I stuck with 1.x and went with 1.2.17, which I had to compile from source. CentOS was originally using /etc as the starting path for Dovecot files but the source distribution puts most of the stuff under /usr/local/etc. After the usual config>make>make install dance I made the necessary changes to point to the new libraries, modules, etc. and the "imap-login: Fatal: Dovecot version mismatch: Master is v1.2.17, login is v1.0.7...." messages went away. After doing this though I cannot login, I get the following error messages: Feb 13 15:50:40 auth(default): Info: client in: AUTH 7 NTLM service=imap lip=192.168.2.102 rip=192.168.2.100 lport=143 rport=1470 Feb 13 15:50:40 auth(default): Info: client out: CONT 7 Feb 13 15:50:40 auth(default): Info: client in: CONT 7 TlRMTVNTUAABAAAAB4IIogAAAAAAAAAAAAAAAAAAAAAFASgKAAAADw== Feb 13 15:50:40 auth(default): Info: client out: CONT 7 TlRMTVNTUAACAAAAMAAwADAAAAAFAooATj7XW6ve2hwAAAAAAAAAADgAOABgAAAAUwBlAHIAdgBlAHIAMQAuAGgAZQByAHMAYwBoAGwAYQB1AHIAZQBuAC4AYwBvAG0AAwAwAFMAZQByAHYAZQByADEALgBoAGUAcgBzAGMAaABsAGEAdQByAGUAbgAuAGMAbwBtAAAAAAA= Feb 13 15:50:40 auth(default): Info: client in: CONT 7 TlRMTVNTUAADAAAAGAAYAGoAAABoAGgAggAAAAAAAABIAAAAEAAQAEgAAAASABIAWAAAAAAAAADqAAAABQKIAgUBKAoAAAAP*CENSORED*bgBiAFEAUwBFAC0AVwBJAE4AWABQAEXO6p/WuopqQ02x1kzJGW3NoQELKw32N88JqkbMOYOVErhiS492elwBAQAAAAAAA*CENSORED*ysN9jcAAAAAAwAwAFMAZQByAHYAZQByADEALgBoAGUAcgBzAGMAaABsAGEAdQByAGUAbgAuAGMAbwBtAAAAAAAAAAAA Feb 13 15:50:40 auth(default): Info: cache(pquesinb,192.168.2.100): miss Feb 13 15:50:40 auth(default): Info: passwd-file(pquesinb,192.168.2.100): lookup: user=pquesinb file=/etc/dovecot.users Feb 13 15:50:40 auth(default): Info: password(pquesinb,192.168.2.100): Requested NTLM scheme, but we have a NULL password Feb 13 15:50:40 auth(default): Info: cache(pquesinb,192.168.2.100): miss Feb 13 15:50:40 auth(default): Info: password(pquesinb,192.168.2.100): passdb doesn't support credential lookups Feb 13 15:50:40 auth(default): Info: cache(pquesinb,192.168.2.100): miss Feb 13 15:50:40 auth(default): Info: password(pquesinb,192.168.2.100): passdb doesn't support credential lookups Feb 13 15:50:40 auth(default): Info: cache(pquesinb,192.168.2.100): miss Feb 13 15:50:40 auth(default): Info: password(pquesinb,192.168.2.100): passdb doesn't support credential lookups Feb 13 15:50:40 auth(default): Info: cache(pquesinb,192.168.2.100): miss Feb 13 15:50:40 auth(default): Info: password(pquesinb,192.168.2.100): passdb doesn't support credential lookups Feb 13 15:50:42 auth(default): Info: client out: FAIL 7 user=pquesinb Looking at the log from the old version while it was working, I was getting messages like the following: dovecot: Feb 04 14:14:21 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 04 14:14:21 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 04 14:15:03 Info: IMAP(pquesinb): Disconnected: Logged out dovecot: Feb 04 14:15:03 Info: IMAP(pquesinb): Disconnected: Logged out dovecot: Feb 04 14:15:23 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 04 14:15:23 Info: imap-login: Login: user=<pquesinb>, method=NTLM, rip=192.168.2.100, lip=192.168.2.102 dovecot: Feb 04 14:16:05 Info: IMAP(pquesinb): Disconnected: Logged out dovecot: Feb 04 14:16:05 Info: IMAP(pquesinb): Disconnected: Logged out /etc/dovecot.users contains a list of usernames. Is this error the result of additional security which has been incorporated into the later version of Dovecot, or is it because my installation of the later version from source is broken, somehow incompatible, etc? Dovecot was configured to use PAM and it appeared to know the password of my account, failing when it was entered incorrectly so I'm assuming that it was successfully using PAM. I kept the same syntax in the later config file. >From dovecot.conf: passdb pam { # [session=yes] [setcred=yes] [failure_show_msg=yes] [max_requests=<n>] # [cache_key=<key>] [<service name>] # # session=yes makes Dovecot open and immediately close PAM session. Some # PAM plugins need this to work, such as pam_mkhomedir. # # setcred=yes makes Dovecot establish PAM credentials if some PAM plugins # need that. They aren't ever deleted though, so this isn't enabled by # default. # # max_requests specifies how many PAM lookups to do in one process before # recreating the process. The default is 100, because many PAM plugins # leak memory. # # cache_key can be used to enable authentication caching for PAM # (auth_cache_size also needs to be set). It isn't enabled by default # because PAM modules can do all kinds of checks besides checking password, # such as checking IP address. Dovecot can't know about these checks # without some help. cache_key is simply a list of variables (see # doc/wiki/Variables.txt) which must match for the cached data to be used. # Here are some examples: # %u - Username must match. Probably sufficient for most uses. # %u%r - Username and remote IP address must match. # %u%s - Username and service (ie. IMAP, POP3) must match. # # The service name can contain variables, for example %Ls expands to # pop3 or imap. # # Some examples: # args = session=yes %Ls args = cache_key=%u dovecot #args = dovecot } If anyone could give me some ideas on where to go from here, I'd really appreciate it. If there's little chance of getting the newer version to work with CentOS 5 then I'm ready to just drop back to the older version.

Re: [Dovecot] Authentication with many Windows AD
by Antonio Alberola 14 Feb '13

14 Feb '13

Hi, > You can set as many databases as you want. Check this: > > http://wiki2.dovecot.org/PasswordDatabase > http://wiki2.dovecot.org/Authentication/MultipleDatabases This solution is valid if I have only one domain. In case you have more than one domain, you need authenticate in the appropriate LDAP server. Is That correct? I'm going to explain my particular case. I have five Windows domains with some users who belong to those domains. I also have other users who are authenticated with local UNIX accounts. The only thing that I can do (I think) is using a Radius server. But, I'd rather not use it.

Fixed in v2.2 now: http://hg.dovecot.org/dovecot-2.2/rev/fb367a977077 Thanks for diagnosing this. I'll probably remove this namespace or limp along until 2.2 becomes the latest stable release. I added this namespace alias in an abundance of caution: this was to prevent users from trying to peruse the entire file space e.g. /etc. A poor man's chroot.

[Dovecot] Authentication with many Windows AD
by Antonio Alberola 14 Feb '13

14 Feb '13

Dear All, I'm a new user of Dovecot and I need support with the authentication process. I use Dovecot 2.0.9 and Postfix 2.6.6 on host x86_64-redhat-linux-gnu 2.6.32-279.14.1.el6.x86_64 CentOS release 6.3 (Final) I need to select the validation method depending on the user. I have users that have to be authenticate with UNIX account, and I have others thats have to be authenticate with Windows AD. For example, some sysadmins and special accounts needs validate with Unix accounts. Other normal users have to authenticate with Windows AD, I have many Windows controllers. Some users authenticate to a specific Windows AD and other users are validated in another one. How I can do this? Thank you very much. Antonio Alberola

[Dovecot] FreeBSD, Dovecot and ZFS
by Jason Lock 13 Feb '13

13 Feb '13

Mail Issues - FreeBSD Hello, my apologies if this may be the wrong forum but hoping that maybe someone might be able to provide some insight. Have a very sporadic and strange issue with our mail servers running Dovecot on FreeBSD. There are three servers hosting Dovecot with FreeBSD as the underlying operating system. All three connect to a NAS server, again running FreeBSD and ZFS. When the specific issue occurs, clients connecting to check mail via POP3 or IMAP experience long delays and timeouts. To the point where POP3 Logins fail due to the timeouts. The issue is further compounded by clients increasing the number of attempts to check mail. Part of the frustration in attempting to diagnose the issue is not knowing the root cause or symptom that initates the issue. Wondering if anyone has experienced anything similar, or suggestions on ways to help identify the root cause

Hello, I'm having to migrate servers. Both are dovecot2 systems. I'm wanting to copy over my mail store from one system to the other. I'd like to preserve dates/times of emails. These are maildir setups on both boxes, I'd like to be as transparent to the end user as possible. I currently have the first dovecot system offline and the second dovecot system is offline. Recommendations? Thanks. Dave.

[Dovecot] dsync 2.1.10 does not correctly handle renames of mailbox subtrees
by Karol Jurak 13 Feb '13

13 Feb '13

Hi, It seems that dsync 2.1.10 does not correctly handle renames of mailbox subtrees. The scenario is as follows. There are two servers, A and B, both running dovecot 2.1.10 and configured to use mdbox. Automatic replication between them is disabled, ie. replication plugin is not active and replicator service has process_min_avail = 0. I perform the following actions: 1. On A: doveadm mailbox create -u test_user a a/b a/b/c d 2. On A: doveadm sync -u test_user -d The result is as expected: on both A and B there are a/b/c and d mailboxes. Now I connect to A via IMAP and rename a/b to d/b. The result is as expected: on A there are a and d/b/c mailboxes. Next I execute on A 'doveadm sync -u mailstoragetest -d' and now the result is not as expected: there are a/b/c and d/b subtrees on both A and B and a/b is just a directory, ie. it does not contain dbox-Mails (the rest are proper mailboxes). dovecot.mailbox.logs have the following records appended to them: A: #2112: rename 33259783092361d18c60ba1c7cfe973c (2013-02-12 10:42:55) - this probably is the rename of a/b to d/b (recursive, ie. including children - in this case a/b/c => d/b/c) by the IMAP client #2136: rename ee2be6da91ae879476b152d7ca041f1b (1970-01-01 01:00:00) - rename of d/b/c to a/b/c by dsync (unexpected/incorrect) B: #1104: rename 33259783092361d18c60ba1c7cfe973c (1970-01-01 01:00:00) - rename of a/b to d/b (non recursive) by dsync What seems to be missing is the record in A's dovecot.mailbox.log describing the rename of a/b/c to d/b/c (or in general case the set of records describing the renames of all the children of a/b). Would appending such records allow dsync to make correct decisions as to which mailboxes and on which servers to rename?

What namespace config do you have? I got more info from the user that had this problem. He reported that he was was setting up a new Email client (Nexus4 Android) and he sent me a screenshot of his setup. Everything look ordinary except perhaps the IMAP prefix set to "mail". My setup documents inform users to leave it blank, but sometimes they use "mail/", a holdover from the uw-imapd days. I provide some aliases for that, but I don't know what would happen if you leave off the trailing "/". My namespace settings as reported by dovecot -n: namespace { inbox = yes location = prefix = separator = / } (The following are aliases to keep backward compatibility) namespace { alias_for = hidden = yes list = no location = prefix = / separator = / } namespace { alias_for = hidden = yes list = no location = prefix = mail/ separator = / } namespace { alias_for = hidden = yes list = no location = prefix = ~/mail/ separator = / } namespace { alias_for = hidden = yes list = no location = prefix = ~%u/mail/ separator = / } I've asked the user to change his prefix, and he'll probably report back.

[Dovecot] Is there any way to mask or hide the INBOX label for Dovecot 1.2.x Shared Mailboxes?
by Jason Discount 13 Feb '13

13 Feb '13

Hello, I'm setting up a new Dovecot sever to replace an old Cyrus server, and need to keep things as consistent as possible. I have a couple local accounts, like junkmail and notjunkmail that users get shared access to, and can drop things in to train sa-update. However, when users share over junkmail's inbox, it's displayed in the hierarchy: • Other Users • junkmail • INBOX Is there any way to get junkmail's INBOX to just show up at Other Users/junkmail and not require that extra depth? • Other Users • junkmail I'm running Debian Squeeze and the standard dovecot package available therein: > # uname -a > Linux internet.digitalquay.com.au 2.6.32-5-xen-amd64 #1 SMP Sun Sep 23 13:49:30 UTC 2012 x86_64 GNU/Linux > #dovecot --version > 1.2.15 I'm running in a configuration where all mail is owned by the vmail user, due to the impression I'm under, that it's a better way if there is to be shared mailboxes.

[Dovecot] Marking messages read / retaining date with Sieve
by Bret Martin 13 Feb '13

13 Feb '13

I'm trying to mark several hundred thousand messages as read as they are delivered via dovecot-lda(1). (I'm importing some mail from another format for migration purposes.) I've been able to do this with Sieve, but it has the side effect that the messages' received and saved dates are set to the current date, and Apple Mail (at least) uses one of these to display the message date. Without the Sieve filter in place, the dates are retained based on the From_ line as I would like. Does anyone know of any way I can either - retain the date when delivering using Sieve? - systematically mark a specific set of messages as read *after* delivery instead, perhaps with doveadm(1)? (even marking *everything* read would work in this particular case. I couldn't find any way to set flags with doveadm) Thanks, --Bret

[Dovecot] POLL: v2.2 to allow one mail over quota?
by Timo Sirainen 12 Feb '13

12 Feb '13

Currently if user is 1MB under quota and someone tries to deliver mail that is over 1MB, Dovecot rejects the mail. But smaller mails aren't rejected probably for days. So user might not even realize that they didn't receive one of the mails. Also having a user "almost over quota" is a rather strange state I think. So what do you think about v2.2 allowing delivery of one last mail even if it brings the user over quota? Except add a limit that if the message size is as much as the user's entire quota limit it wouldn't be added (or 50% or ..?). Also IMAP wouldn't allow this, since user would get an error anyway. I could make this also optional, but if nobody really wants to keep the old behavior there's really no point in adding the option.

[Dovecot] Keyword Flags
by David Woodfall 11 Feb '13

11 Feb '13

I mostly use Mutt to read mail but today I fired up Thunderbird. I have a shell script that looks for new mail, which looks for files in cur/ and new/ ending with the server hostname or a comma. When I fired up TB it seems that all new mail has been given a flag of ,a which I gather means it matches a keyword. My questions are: How did this happen? Did TB do something strange to my mail when it fetched headers? If I change my search parameters to ',[a-z]' will this only catch new mail?

[Dovecot] Disabling auth caching just from one passdb
by Angel L. Mateo 11 Feb '13

11 Feb '13

Hello, I'm using various password databases (one of them is a ldap database, which is the used for users connecting with email clients, and the other with pam, using a pam module integrated with our SSO that is used from our webmail). I would like to disable password caching in my pam database (because 'passwords' provided by our SSO are single use tokens, so caching them has no benefit), but not in the ldap. As far as I know, auth_cache_size is the option to enable caching in all databases. But, is there any option I could use to disable it in a specific password database? -- Angel L.

Then the problem seemed to have went away. I logged back as that user using a master password, but couldn't recreate this problem. The backtrace is just hex numbers (stripped executables) and I didn't drop privileges, so it refused to drop core, so that's no help. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] Moving index files on another disk: no troubles but need more assurances
by Paolo Miotto 11 Feb '13

11 Feb '13

Hi, I'm using dovecot 1.2.15 on debian squeeze with maildir, and I want to move index files out of the mailboxes disk to reduce disk I/O. I need to get the assurance that the switch is completely transparent to my clients (IMAP and POP). I read the wiki documentation and have found this thread (http://dovecot.org/pipermail/dovecot/2009-September/042665.html) which makes me confident, even if it speaks of a older version and only pop3. So I set up a test server, copied a true mailbox and changed mail location from: mail_location = maildir:~/Maildir to mail_location = maildir:~/Maildir:INDEX=/srv/indexes/%1n/%n (all users under the same domain, no need to use %d). On the IMAP side all seems to work fine, new indexes are created in the new location (dovecot.index.log on 1st access, dovecot.index.cache on message manipolation). A test client (evolution) doesn't notice at all, and I have verified via a telnet imap session that UIDs don't change. But I see that when I move the indexes the IMAP HIGHESTMODSEQ response changes and is reset to 1. Can this baffle the clients? On the rfc I don't found reference to this status walking backwards. Need I to verify that all messages have the virtual size (W=nnnn) in the file name (the mailboxes are from a previous cyrus installation, then we switch to dovecot 1.2)? What other test you suggest that checking UIDL on the pop3 side? What happens if the indexes disk disappears (broken or removed from bay or all paths down for FC/iscsi)? Can dovecot 1.2 continue with INDEX=MEMORY as for a disk full? Sorry for the many questions....

[Dovecot] cPanel && Dovecot 2.x
by Marc Jauvin 10 Feb '13

10 Feb '13

I would like to know if dovecot 2.0.9+ can work with cPanel. I know there is a template for it in cPanel 11.34.1, but when I tried to switch to 2.0.9 (from 1.2.17), it didn't work. I didn't put too much time to test it since I only have one live system to test it with, and I have many customers hosted on this server and I cannot disrupt the service. Has anyone been able to make this work, and if so, is there anything special to do other than rebuilding the config with "/scripts/builddovecotconf" ? Thanks.

[Dovecot] GSS-SPNEGO with dovecot and Outlook without Samba

I am trying to configure a dovecot2 IMAP server to inter-operate with a active directory to authenticate users. The users should be able to login without a password on a domain-joined client(Outlook). Is it possible to do this only with kerberos? I don't want to put a crappy winbind on my mailserver... I already configured my server to authenticate via kerberos(GSSAPI), but Outlook does not even try to authenticate using GSSAPI, it rather uses PLAIN. I would appreciate any help, many thanks in advance.

[Dovecot] dsync timeout?
by Micah Anderson 08 Feb '13

08 Feb '13

I'm using dsync for a regular backup. The backup system flocks so that two cannot run at the same time, which is generally a good thing. The problem is that it seems like dsync sometimes goes off into the weeds and never comes back, leaving a process running and doing nothing forever, hogging the lock and causing my backups never to run again. I just finally figured out that was what was causing the backups not to run on this system was this process: root 17836 0.0 0.0 40888 1600 ? S 2012 0:00 ssh -i /root/.ssh/backmaildir_id_rsa backmaildir@arg /usr/bin/dsync -u foobar server yeah, that has been running since 2012 :( root:/tmp# strace -p 17836 Process 17836 attached - interrupt to quit select(8, [4], [], NULL, NULL very exciting... There doesn't seem to be a timeout in dsync, but perhaps there should be? At this point my only option is to write a cronjob that will look for dsync processes that are over a certain amount of time old and then kill them, after I do that I will need to take a shower because that is a very dirty solution :P thanks for any ideas, or help! micah --

[Dovecot] Dovecot-2.1.14 - pop3 processes always hangs forever - a follow-up

Suspecting a problem with the "virtual" uids/gids, I've tried with a real user for the mail user: # 2.1.14: /_ETC/dovecot/dovecot.conf # OS: Darwin 12.2.1 x86_64 auth_verbose = yes disable_plaintext_auth = no mail_debug = yes mail_gid = dovemailer mail_location = mbox:~/mboxes:INBOX=~/mboxes/inbox mail_uid = dovemailer passdb { args = /_ETC/dovecot/db.conf driver = sql } ssl = no userdb { driver = prefetch } Of course, the db queries do not return uid/gid pairs anymore. And the pop3 processes now seem to work as expected; connecting for the first time as user1: $ telnet 127.0.0.1 110 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Dovecot ready. user user1 +OK pass pass1 +OK Logged in. list +OK 0 messages: . quit +OK Logging out. Connection closed by foreign host. Hmmm... Axel

[Dovecot] Dovecot-2.1.14 - pop3 processes always hangs forever
by Axel Luttgens 08 Feb '13

08 Feb '13

Hello, I'm currently experimenting with the 2.1.x series and am facing a behavior I can't explain; I must be doing something wrong and probably miss the obvious... ;-) This is a very basic build on Mac OS X 10.8.2: ./configure --prefix=/_COD/dovecot-2.1.14 --sysconfdir=/_ETC --localstatedir=/_VAR --with-sqlite --with-ldap=yes (Yes, I know, a strange layout, yet very convenient for testing various things here.) Dovecot's configuration is very basic too: # 2.1.14: /_ETC/dovecot/dovecot.conf # OS: Darwin 12.2.1 x86_64 auth_verbose = yes disable_plaintext_auth = no mail_debug = yes mail_location = mbox:~/mboxes:INBOX=~/mboxes/inbox passdb { args = /_ETC/dovecot/db.conf driver = sql } ssl = no userdb { driver = prefetch } It is started from launchd with the -F flag. Two users are defined in the database, user1 (100002/100002) and user2 (100003/100003), with "virtual" uids/gids.

[Dovecot] dsync: Invalid server handshake
by Dusan Zivadinovic 08 Feb '13

08 Feb '13

Hi list, I recently tried to backup mailboxes from an older server machine to a new one in order to move the service to the new machine. Both machines are in the same LAN, I used this command: dsync -R -u username backup ssh -i .ssh/id_rsa username(a)192.168.1.11 /opt/local/bin/dsync and I get this error: dsync-local(dz): Error: Invalid server handshake: dsync-server 2 dsync-remote(dz): Error: Invalid client handshake: dsync-client 1 # lokal machine: dovecot 2.0.19apple1 running on Mac OS X 10.8.2 Server using standard Apple-Dovecot-Configuration # remote machine: 2.1.12 running on Mac OS X 10.4 using PAM authentication I cant seem to find any documentation to this error, nor do I find any dsync entries in the logs of both machines. Does anyone have a hint? Thank you, Dusan

[Dovecot] File permissions used for automatically created mailbox
by Frerich Raabe 07 Feb '13

07 Feb '13

Hi, I'm running Dovecot 2.1.12 on FreeBSD (quite successfully so, thanks for this nice piece of software!). One thing which is slightly annoying though is that automatically created mailboxes (I have lda_mailbox_autocreate set) don't have the file permissions I'd like them to have. I'm using a vmail-based system, i.e. all mail is owned by vmail:vmail; another member of the vmail group is called 'backup', which has read access to all mail in order to create backups. All mail is stored beneath /home/vmail, e.g. /home/vmail/frerich/Maildir Right now, newly created mailbox directories (e.g. /home/vmail/bob) have 0700 permissions, but I'd like to have 0750 for all directories and 0640 for all files so that all files and directories are group-readable for backup purposes. Does anybody know whether this is configurable somehow? Right now, my workaround consists running this cron script every night: #!/bin/sh chown -R vmail:vmail /home/vmail/ find /home/vmail/ -type d -print0 | xargs -0 chmod 0750 find /home/vmail/ -type f -print0 | xargs -0 chmod 0640 -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing

[Dovecot] Subfolders problem
by Adam Maciejewski 06 Feb '13

06 Feb '13

I have moved from dovecot 1.x to 2.x and I have big problem with subfolders. When I'm moving subfolder with other subfolders is moving only main subfolder, without subfolders, example : mail-storage-1 /var/vmail/home/adamskitest/mdbox/mailboxes # find | egrep -e "janusz|jarek" ./jarek ./jarek/dbox-Mails ./jarek/dbox-Mails/dovecot.index.log ./jarek/jarek2 ./jarek/jarek2/dbox-Mails ./jarek/jarek2/dbox-Mails/dovecot.index.log ./jarek/jarek2/jarek3 ./jarek/jarek2/jarek3/dbox-Mails ./jarek/jarek2/jarek3/dbox-Mails/dovecot.index.log ./janusz ./janusz/dbox-Mails ./janusz/dbox-Mails/dovecot.index.log ./janusz/janusz2 ./janusz/janusz2/dbox-Mails ./janusz/janusz2/dbox-Mails/dovecot.index.log ./janusz/janusz2/janusz3 ./janusz/janusz2/janusz3/dbox-Mails ./janusz/janusz2/janusz3/dbox-Mails/dovecot.index.log And now I'm moving jarek2 with jarek3 as subfolder to janusz2 subfolder, result : mail-storage-1 /var/vmail/home/adamskitest/mdbox/mailboxes # find | egrep -e "janusz|jarek" ./jarek ./jarek/dbox-Mails ./jarek/dbox-Mails/dovecot.index.log ./jarek/jarek2 ./jarek/jarek2/jarek3 ./jarek/jarek2/jarek3/dbox-Mails ./jarek/jarek2/jarek3/dbox-Mails/dovecot.index.log ./janusz ./janusz/dbox-Mails ./janusz/dbox-Mails/dovecot.index.log ./janusz/janusz2 ./janusz/janusz2/dbox-Mails ./janusz/janusz2/dbox-Mails/dovecot.index.log ./janusz/janusz2/dbox-Mails/dovecot.index.cache ./janusz/janusz2/janusz3 ./janusz/janusz2/janusz3/dbox-Mails ./janusz/janusz2/janusz3/dbox-Mails/dovecot.index.log ./janusz/janusz2/jarek2 ./janusz/janusz2/jarek2/dbox-Mails ./janusz/janusz2/jarek2/dbox-Mails/dovecot.index.log As You can see there is jarek2 subfolder but jarek3 havent been moved.

[Dovecot] Sieve not filtering
by Nicolas Mora 06 Feb '13

06 Feb '13

Hello, I installed a few weeks ago the Dovecot package on a Debian stable along with postfix, everything works fine except the sieve filter. I followed the howto found on the internet (google: debian postfix dovecot sieve). I'm able to view and modify sieve rules with roundcube or thunderbird plugins, but the rules are not applied when a message arrives and all messages arrive in INBOX. Here is the content of my configuration files concerning sieve : dovecot.conf protocols = imap imaps managesieve protocol managesieve { listen = *:2000 } protocol managesieve { mail_executable = /usr/lib/dovecot/managesieve managesieve_max_line_length = 65536 managesieve_logout_format = bytes=%i/%o } protocol lda { postmaster_address = postmaster(a)babelouest.org mail_plugins = sieve mail_plugin_dir = /usr/lib/dovecot/modules/lda log_path = info_log_path = syslog_facility = mail } plugin { sieve_dir=~/Maildir/sieve } And the postfix/main.cf config file contains for dovecot sieve the following maibox_command = /usr/lib/dovecot/dovecot-lda -f "$SENDER" -a "$RECIPIENT" dovecot_destination_recipient_limit = 1 virtual_transport = dovecot I also tried the command mailbox_command = /usr/lib/dovecot/deliver it didn't work either... Is there somthing so obvious that I didn't see it ? Thanks in advance

[Dovecot] move mail from server with v1.0 to server w. v2.1?
by Frank Lienhard 06 Feb '13

06 Feb '13

I'm about to replace my old server. Both servers are on my internal network. The old one ist running debian lenny(32bit) with dovecot 1.0.15 and the new one debian Wheezy with dovecot 2.1.7. I set up the users on both systems identically (same gid uid). My first attempt was tho simply rsync the Maildirs along with the homes. Both deovecot versions are set up with the maildir format, but this results in ~30% doublicated mails on the new server. I then learned about doveadm/dsync, only to figure out that this isn't available in v 1.0.15 and therefor won't work. So which could be the most painless way to solve that?

[Dovecot] dsync backup questions
by Joe Beaubien 06 Feb '13

06 Feb '13

Hi, I'm currently trying to setup remote backups of my emails but i'm running into issues (mdbox format, indexes and storage in the same folder hierarchy). Local backup command: dsync -u "my_user" backup /backups/my_user (1) Recently, I noticed that the local backup takes up twice the size as the original mail location (8gb vs. 4gb). I purged alot of emails from the original location, so the size shrunk, but the local backup just keeps on getting bigger. I couldn't find any dsync option that would delete extra emails. - Question: Why isn't the local backup synced properly and remove the extra emails? (2) What is the best why to copy this local backup to a remote location that does NOT have the possibility to run dsync. - Question 1: is rsync safe to use and will this data work for restore? - Question 2: Would it be safe to simply rsync the original mail_location to the remote server? I searched the net, but it seems that mdbox is tricky to backup. Thanks in advance, -Joe

[Dovecot] Upgrade from 2.1.13 to 2.1.14 and load doubled
by Alessio Cecchi 05 Feb '13

05 Feb '13

Hi, during the weekend I upgrade my mail servers from dovecot 2.1.13 to dovecot 2.1.14 (and rebuild dovecot-2.1-pigeonhole-0.3.3).

[Dovecot] lmtp-proxying in 2.1 slower than in 2.0.14 ?
by Jan-Frode Myklebust 05 Feb '13

05 Feb '13

We upgraded our two dovecot directors from v2.0.14 to dovecot-ee 2.1.10.3 this week, and after that mail seems to be flowing a lot slower than before. The backend mailstores are untouched, on v2.0.14 still. After the upgrade we've been hitting process_limit for lmtp a lot, and we're struggeling with large queues in the incoming mailservers that are using LMTP virtual transport towards our two directors. I seem to remember 2.1 should have a new lmtp-proxying code. Is there anything in this that maybe needs to be tuned that's different from v2.0 ? I'm a bit scheptical to just increasing the process_limit for LMTP proxying, as I doubt running many hundreds of simultaneous deliveries should work that much better against the backend storage.. ###### doveconf -n ########## # 2.1.10.3: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-194.32.1.el5 x86_64 Red Hat Enterprise Linux Server release 5.5 (Tikanga) default_client_limit = 4000 director_mail_servers = 192.168.42.7 192.168.42.8 192.168.42.9 192.168.42.10 192.168.42.28 192.168.42.29 director_servers = 192.168.42.15 192.168.42.17 disable_plaintext_auth = no listen = * lmtp_proxy = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave passdb { args = proxy=y nopassword=y driver = static } protocols = imap pop3 lmtp sieve service anvil { client_limit = 6247 } service auth { client_limit = 8292 unix_listener auth-userdb { user = dovecot } } service director { fifo_listener login/proxy-notify { mode = 0666 } inet_listener { port = 5515 } unix_listener director-userdb { mode = 0600 } unix_listener login/director { mode = 0666 } } service imap-login { executable = imap-login director process_limit = 4096 process_min_avail = 4 service_count = 0 vsz_limit = 256 M } service lmtp { inet_listener lmtp { address = * port = 24 } process_limit = 100 } service managesieve-login { executable = managesieve-login director inet_listener sieve { address = * port = 4190 } process_limit = 50 } service pop3-login { executable = pop3-login director process_limit = 2048 process_min_avail = 4 service_count = 0 vsz_limit = 256 M } ssl_cert = </etc/pki/tls/certs/pop.example.com.cert.ca-bundle ssl_key = </etc/pki/tls/private/pop.example.com.key protocol lmtp { auth_socket_path = director-userdb } ################ -jf

[Dovecot] dsync-local(user): Error: proxy client timed out
by Metro Domain Admin 05 Feb '13

05 Feb '13

Hello, I have an intermittent but frequent problem using dsync backup. The command outputs: dsync-local(user): Error: proxy client timed out Then dies with exit code 75. Any subsequent attempts to re-run the backup invariably fail like this: dsync-local(user): Warning: Destination mailbox INBOX has been modified, need to recreate it before we can continue syncing dsync-local(user): Error: read() from worker server failed: EOF dsync-local(user): Error: msg-copy returned invalid input: dsync-local(user): Error: remote: dsync-remote(user(a)domain.com): Error: Can't delete mailbox INBOX: INBOX can't be deleted. dsync-remote(l_user(a)domain.com): Error: command MSG-SAVE failed dsync-local(user): Warning: Mailbox changes caused a desync. You may want to run dsync again. The syntax I am using is: dsync -u $user backup \ ssh -i <idfile> <user@host> \ dsync -u l_$user We have this running in a script that loops through all users. The error happens mostly on the larger mailboxes but I've seen it succeed on the largest ones then fail on smaller. One mid-sized account now fails consistently. The backup is running from a Mac OS PPC server running 2.1.12 The target is a Linux Intel box running 2.1.13, but I had the same problem sending to a Mac OS Intel on 2.1.12. Mdbox in all cases. Thanks, Tony

[Dovecot] Overloading IMAP Server
by Harford, Ken 04 Feb '13

04 Feb '13

Hi All, I am having an issue with dovecot IMAP reading and writing to one specific mailbox. I have a check email delivery script that sends out a email and then logs into dovecot to check if the mailbox that the message has been delivered to. However, the servers that send these messages send them in bunches depending on how many postfix spools it is checking. So I could get 60 messages all being sent to 1 mailbox and then having to read that same mailbox to check if the message actually got delivered. I am using postfix as the MTA and dovecot is actually delivering the message to the mailbox I am getting a lot of errors such as the following: Could not connect to IMAP server imap failed: IMAP RECEIVE CRITICAL - Could not select INBOX Any ideas as to what I can tweak in dovecot to allow these messages to be verified. Thanks for any information or help you could provide!! Ken

[Dovecot] Reviewing end-user ham/spam submissions before feeding them to sa-learn via Dovecot Antispam plug-in
by Ben Johnson 01 Feb '13

01 Feb '13

Currently, I'm using the Dovecot Antispam plug-in with great success. Everything works as expected. However, I would like to change the plug-in's behavior such that it simply sends a copy of a message that is moved from Inbox -> Junk (or Junk -> Inbox) to an administrator, instead of calling sa-learn (I'm using SpamAssassin) automatically. Basically, I would like to be able to review messages that end-users submit for training before they are actually fed to sa-learn. Has anyone had a similar need? If the Antispam plug-in already supports this, if the necessary commands can simply be added to the shell script that Antispam calls, or if there is a better method altogether, any help is greatly appreciated. Thank you! -Ben

[Dovecot] Dovecot Director Doveadm fails when there are a lot of output information
by Ramon Frontera 31 Jan '13

31 Jan '13

Hi, we are running dovecot 2.1.13 We have 2 proxies with director and 4 mail servers. we use LDAP when we execute doveadm-quota -A and doveadm with few output lines, its works fine. When we use doveadm-search or doveadm-mailbox with a lot of output information the command stops the execution and the command no ends. The connection to one of the 4 mailserver has finished at this moment. I have made some tests and i have found that if we use only one mailserver the commands works fine. I put the gdm bt output hope it help you.

[Dovecot] sieve_max_redirects=0 not working as documented
by Arnaud Abélard 31 Jan '13

31 Jan '13

Hello I'm trying to keep my users from using the "redirect" action with pigeonhole from dovecot 2.0.21. As documented in http://wiki2.dovecot.org/Pigeonhole/Sieve/Configuration I configured sieve like this: plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_max_redirects = 0 } (and doveconf indeed shows the new setting for sieve_max_redirects) Unfortunately I can still use the redirect action: lda(dummy(a)univ-nantes.fr): Debug: sieve: executing script from /vmail/d/u/dummy/.dovecot.svbin lda(dummy(a)univ-nantes.fr): sieve: msgid=<510A758D.1030305(a)univ-nantes.fr>: forwarded to <xxxx(a)xxxxx.com> what could I have missed?

[Dovecot] v2.1.14 released
by Timo Sirainen 30 Jan '13

30 Jan '13

http://dovecot.org/releases/2.1/dovecot-2.1.14.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.14.tar.gz.sig If you've been waiting for a fully stable release after the recent cache file troubles in v2.1.11+, this release should be the one. Hopefully there won't be v2.1.15 anytime in near future. (v2.2.rc1 does look close though.) BTW. I know there are quite a lot of mails I haven't replied to in dovecot list. Too busy for now.. + doveadm acl recalc command added - v2.1.11+ had a race condition where it sometimes overwrote data in dovecot.index.cache file. This could have caused Dovecot to return the same cached data to two different messages. - mdbox: Fixes to handling duplicate GUIDs during index rebuild

[Dovecot] decode2text.sh
by bhs692-dove＠yahoo.com 30 Jan '13

30 Jan '13

Dovecot version: 2.1.13 OS: Centos 6.3 CPU: 64bit x86 There appear to be two related errors in the decode2text.sh file (which can be used for indexing/ searching attachments). - The layout of "$formats" has repeated values for pdf, ppt, etc, so you should only match the pattern once by adding -m1 - The layout of "$formats" has the file extension in the second "column", so the "start of line"(^) match doesn't work as is. Original problem line (from ./src/plugins/fts/decode2texh.sh): fmt=`echo "$formats" | grep -w "^$content_type" | cut -d ' ' -f 2` Here are two options that appear to solve the problem. The first option is probably preferred, since it matches exactly the extension to the second "column". 1) switch the order of commands (cut & grep) and add -m1. for example: fmt=`echo "$formats" | cut -d ' ' -f 2 | grep -w -m1 "^$content_type"` -OR- 2) add "m1" and remove "^". for example: fmt=`echo "$formats" | grep -w -m1 "$content_type" | cut -d ' ' -f 2`

[Dovecot] passdb to add extra fields?
by Timo Sirainen 30 Jan '13

30 Jan '13

Some passdbs like PAM can't really return any extra fields. Also some people have wanted to combine users' data from different passdb/userdbs so that for example you'd have userdb passwd give the uid/gid/home, but then you'd also have some other userdb give quota limits. So I was thinking something like this: passdb { driver = pam } passdb { driver = sql include = yes } or: userdb { driver = passwd } userdb { driver = passwd-file include = yes } I'm not sure about two things: 1) Should there be a way to replace all of the existing fields instead of just adding new ones? 2) Any thoughts of a better name than "include"? With passdb it would mean that it's included only when the authentication failed for some other passdb. With userdb it means it's included only if a previous userdb lookup succeeded. Also there are already "deny" and "pass" settings. Interaction with them can be somewhat confusing.. Maybe all of these should be replaced with: type=deny: Same as old deny=yes (deny auth if user is in list) type=precondition(?): Same as pass=yes (require another passdb to match) type=postcondition(?): Require user to exist in this passdb/userdb as well, adding any extra fields in it. type=add: Add any extra fields, if the user exists at all. (Better ideas for the names here? Is even "type" a good name?) Then maybe a new setting to delete existing extra fields .. or perhaps just extend passdb { override_fields } so that having "-field" would delete the field if it already existed..

[Dovecot] A lot of dovecot/imap processes
by Juan Cifo Servera 30 Jan '13

30 Jan '13

Hello! I have a dovecot installed and many users could login via IMAP over SSL (40 users at same time aprox). Users could have "Check mail every X time" enabled in their client (Thunderbird or K-9 mail) - Is this required feature? I noted that if I disable it I still getting news mails without having to check for new mails manually - . I noted that dovecot is creating a lot of process (dovecot/imap and dovecot/imap-login) and is requiring more and more RAM. I think that every login starts a process but never is endend. The output of /*ps aux | grep dovecot | wc*/ is increasing until 250 lines aprox. I think that is limited by process_limit = 256. But if I put process_limit = 100, in the log appers a message that dovecot is aborting logins (and I noted that new connections sometimes couldn't login). Anyway the mailserver is working well, but I'm afraid of the consumtion of RAM. Is that normal?

Is there any documentation anywhere on creating a new storage plugin besides looking through the existing storage code? It's a pretty extensive task and any documentation would help. Thanks

[Dovecot] help with public namespace/mailbox
by michael＠los-pollos.co 30 Jan '13

30 Jan '13

Dear all, I am hoping someone can help me with a problem that I have been trying to fix for days. Using postfix and dovecot 2.0.19 on Ubuntu 12.04 with LDAP authentication and virtual users and domains. Basically I want to setup both shared and public mailboxes. The shared part is working fine, ie I can share folders successfully and other uses can see them. However when I try and create sub folders in the public folder they don't show up in the client. I have tried creating them in manually in the filesystem ie mkdir .folder and also via thunderbird. I have read through the dovecot wiki's several times over and still cannot see why it won't work. I have debug turned on and these are the log messages I get in syslog when I start up thunderbird: acl: No lookup right to mailbox: public/folder acl vfile: file /home/example.com/public/.folder/dovecot-acl not found acl vfile: file /home/example.com/public/dovecot-acl not found So I create the dovecot-acl file manually in public and set the right file system permissions and the errors go away, yet the folder still doesn't get created despite the following getting logged in syslog. Jan 29 23:43:57 alpha dovecot: imap(testuser(a)example.com): Debug: Namespace public/: /home/example.com/public/.folder2 doesn't exist yet, using default permissions Jan 29 23:43:57 alpha dovecot: imap(testuser(a)example.com): Debug: Namespace public/: Using permissions from /home/example.com/public: mode=0777 gid=-1 Right now I am thinking the problem might be that I am trying to setup both shared and public namespaces within the same configuration and therefore dovecot is looking for acl's for the public when it shouldn't be? Feel like I am stabbing in the dark with this though. Any help anyone can offer will be greatly appreciated! Thanks in advance. Regards, Michael.

[Dovecot] Duplicate supression mechanism

Hello, In a Dovecot 2.0.6 server I have an account x@domain and an alias y@domain -> x@domain. When I send an email to x@domain with carbon copy to y@domain, X receives two messages on mailbox. Dovecot2 has any feature of duplicate suppression ? Thanks -- Thiago Henrique adminlinux.com.br

[Dovecot] dovecot.index is missing
by Alexandr Sabitov 30 Jan '13

30 Jan '13

Dear All, I have noticed that dovecot.index is not generated straight away if you have just a few emails in the mailbox. Instead of that dovecot.index.log is modified and accessed by clients. Only if the number of email reaches some level then it creates dovecot.index in user mailboxes. Can somebody please tell me when (in my understanding of the process) the index log file drops all data into the mail index file. What does trigger that ? Sorry I couldn't find any info on that in the wiki. Best Regards, Alexandr Sabitov

[Dovecot] password schemes in dovecot
by Public 28 Jan '13

28 Jan '13

Hey there, I'm using the latest dovecot 2.1.13 In the wiki http://wiki2.dovecot.org/Authentication/PasswordSchemes BLF-CRYPT is listed, but i can't use it. "doveadm pw -l" doesn't show it. And i'm unsure about how I am supposed to use the different SHA schemes, since they always output different hashes for the same password. MD5 is working fine, but I'd rather not use it. Is the wiki outdated or how do i get BLF-CRYPT working? thanks, simon

[Dovecot] From Sendmail to Dovecot mdbox, what is missing.
by Torpey List 27 Jan '13

27 Jan '13

Sendmail 8.14.4 dovecot 2.0.9 I have sendmail working and it is sending mail to /var/mail/%u. I have dovecot working in that I can move emails into IMAP folders and I can send email through IMAP. I have set up dovecot to use mdbox based on the following: mail_location = mdbox:~/mail However, I seem to be lacking a key piece of information. Sendmail is sending the mail to /var/mail/%u as a mbox (single file for all emails) format. Dovecot wants to read the mail in mdbox (Multiple messages per file, but unlike mbox multiple files per mailbox.) So the two programs are not working together. So, I cannot get dovecot to read new emails at /var/mail/%u. So I tried changing to the following: mail_location = mdbox:~/mail:INBOX=/var/mail/%u However, dovecot complains that it is NOT a directory. That is because sendmail is sending as mbox format. I have tried two lines of “mail_location” but that did not work. example mail_location = mdbox:~/mail ----> for dovecot mail_location = mbox:INBOX=/var/mail/%u -----> for sendmail I have tried LMTP and dovecot-lda. LMTP – I could not see any difference with this added or not. Dovecot-lda – I have had issues getting it configured. Thanks for any help!

[Dovecot] mbox INBOX out of sync (?)
by Tinguaro Barreno Delgado 26 Jan '13

26 Jan '13

Hello all, I've running a Dovecot's installation for several years without problems but since last system upgrade (Dec 26) I'm facing a kind of sync issue with the /var/mail/ inbox files. We have got mobile and desktops IMAP clients (mostly Mozilla Thunderbird). The problem is that /var/mail/ files (mbox) aren't updated: we can delete mail from clients but they persist in de /var/mail, so the same user can see the mail again from other IMAP client. Logs seems to be correct. Many thanks in advance.

[Dovecot] Dovecot unable to access the shadow file
by kenwood 25 Jan '13

25 Jan '13

I am installing Dovecot-2.1.13 on Slackware 13.37.0 for the first time to replace ipop3d and I have overcome all of the roadblocks as they have developed except this last one and I finally have to say “uncle”. The error messages that are showing up in the dovecot.log are as follows.

With that in mind I looked at all the configuration and .ext files and the only file I could find that would indicate that root should be checking the shadow file is 10-master.conf. In that file it said the default service auth-worker was root but since it was apparently not working I removed the hash mark and made it explicit. It still didn’t work. As a last resort even though it was not good practice I tried adding user dovecot to the group shadow but that did not work either. It still says dovecot is not in the group shadow even though it is.

[Dovecot] dovecot 2.1.13, proxy and nologin extras field
by Marco Giunta 24 Jan '13

24 Jan '13

Hi at all, in our test environment, I'm playing with dovecot 2.1.13 configured as imap/pop/managesieve proxy. It is configured to authenticate users with ldap and it works very well. Now, I'd like to temporary disable some users's login, because we are moving to another storage, and I wouldn't stop imap service at all. I've found on Dovecot wiki that I could use 'nologin' extra field, but I wasn't been able to get it work. My dovecot configuration is: # 2.1.13: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.19.1.el6.x86_64 x86_64 ... auth_debug = yes auth_debug_passwords = yes auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no listen = * mail_debug = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave mbox_write_locks = fcntl namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap pop3 sieve service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } } ssl = no ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = prefetch } and my 'dovecot-ldap.conf.ext' is: uris = ldap://ldap.example.it/ dn = "cn=Reader,dc=example,dc=it" dnpass = password base = ou=People,dc=example,dc=it pass_attrs = uid=user,userPassword=password,\ =userdb_home=/var/spool/mail/%1u/%u,uidNumber=userdb_uid,gidNumber=userdb_gid,\ =proxy=y,=host=imap.example.it,\ =nologin=y pass_filter = (&(objectClass=qmailUser)(uid=%u)(accountStatus=active)) With this configuration, all users can login, and log said: Jan 23 09:16:18 localhost dovecot: master: Dovecot v2.1.13 starting up (core dumps disabled) Jan 23 09:16:33 localhost dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Jan 23 09:16:33 localhost dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Jan 23 09:16:33 localhost dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Jan 23 09:16:33 localhost dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so Jan 23 09:16:33 localhost dovecot: auth: Debug: auth client connected (pid=3660) Jan 23 09:16:33 localhost dovecot: auth: Debug: client in: AUTH#0111#011PLAIN#011service=imap#011session=PsbzT/DT+gCTeiwf#011lip=192.168.129.109#011rip=192.168.44.31#011lport=143#011rport=53754 Jan 23 09:16:33 localhost dovecot: auth: Debug: client passdb out: CONT#0111#011 Jan 23 09:16:33 localhost dovecot: auth: Debug: client in: CONT#0111#011AHByb3ZhZm0AY2hlcGFsbGU= Jan 23 09:16:33 localhost dovecot: auth: Debug: ldap(prova,147.122.44.31,<PsbzT/DT+gCTeiwf>): pass search: base=ou=People,dc=example,dc=it scope=subtree filter=(&(objectClass=qmailUser)(uid=prova)(accountStatus=active)) fields=uid,userPassword,uidNumber,gidNumber,uid,uid Jan 23 09:16:33 localhost dovecot: auth: Debug: ldap(prova,192.168.44.31,<PsbzT/DT+gCTeiwf>): result: uid=prova uidNumber=2944 gidNumber=650 userPassword={MD5}BjbsTtSovVAs1csswBTI7Q== Jan 23 09:16:33 localhost dovecot: auth: Debug: client passdb out: OK#0111#011user=prova#011proxy#011host=imap.example.it#011nologin#011hostip=192.168.11.136#011pass=password Jan 23 09:16:33 localhost dovecot: imap-login: proxy(prova): started proxying to imap.example.it:143: user=<prova>, method=PLAIN, rip=192.168.44.31, lip=192.168.129.109, session=<PsbzT/DT+gCTeiwf> As you can see 'nologin' field is present in 'passdb' answer, but it doesn't seem to work.

[Dovecot] Permissions when running `dovecot --exec-mail imap`
by Tim Marston 24 Jan '13

24 Jan '13

Hi, I'm running dovecot 1.2.15, on Debian squeeze. /var/mail is owned by group "mail" with permissions "g+rwxs,o=". The mail_privileged_group setting is set to "mail". I am trying to access mail on a remote machine with mutt by tunnelling mutt though ssh and running `dovecot --exec-mail imap` on the mail server. But I frequently get errors in the mail server's logs about not being able to create dotlock files when accessing my INBOX this way. This makes sense -- I'm running dovecot as a regular user, so it isn't able to write to /var/mail as group "mail". I notice that on the dovecot wiki[1] it is suggested that sudo is used to set uid/gid before running `dovecot --exec-mail imap`. But I don't actually want to set the uid, just the gid. And I also have sudo disabled at the moment. So I was wondering about another solution... Would it be acceptable to setgid the dovecot executable and change it's group to "mail" (i.e., `chgrp mail dovecot` and `chmod g+s dovecot`)? Would this pose some kind of security risk? Would this actualy do what I want, or am I missing a bigger picture? Kind regards, [1] http://wiki.dovecot.org/PreAuth -- Tim Marston ed.am

[Dovecot] warning regarding quota and mboxes

Hello! We drive mboxes and maildirs and the dovecot-server is running very well and everthing is fine, but I get the following warning in the dovecot-lda-errors.log when a mail is delivered to a mbox. Jan 10 16:29:24 lda(archiv(a)bitcorner.de): Warning: quota: Namespace '' is not Maildir, skipping for Maildir++ quota This is what I defined in the dovecot.conf: mail_home = /var/spool/vhosts/%d/%n mail_location = mbox:~/:maildir:~/ mail_plugins = quota plugin { quota = maildir:User quota quota_rule = *:storage=500MB quota_rule2 = Trash:storage=+10%% } Can I avoid the error above somehow? Namespaces are a bit mysterious for me at the moment. Greetings Andreas

[Dovecot] speed up dovecot IMAP server
by Bernics Gábor | Penta Unió Zrt. 23 Jan '13

23 Jan '13

Hello, I upgraded my dovecot server (1.2 -> 2.1), from debian backport because it was a little slow (wait 5-6 sec) when I opened some mail (but not every mail). Unfortunately, the mail open speed didn't increase. I think it's an index problem. Have you idea for fixing?

[Dovecot] Fixing bad maildir message sizes
by Richard Platel 23 Jan '13

23 Jan '13

Hello. As stated in my previous message, we have some old compressed maildir messages with incorrect sizes in the filename. These messages cause dovecot 2.x problems. I'm trying to write a script to crawl all our messages, check the actual message size and if necessary, fix the filename. However, when I do this, dovecot gives the message a new UID on next login. If I change the filename in dovecot-uidlist, dovecot still gives a new UID on next login. If I change dovecot-uidlist and delete the index, then the UID is preserved. Re-indexing our millions of mailboxes is not a great solution for us. Is there a good way to fix this?

[Dovecot] question on "doveadm user" and pass/userdb
by Gábor Lénárt 22 Jan '13

22 Jan '13

Hi, I'm about getting to know dovecot in details, I am about the command "doveadm user". The man page shows this example: userdb: jane uid : 8001 gid : 8001 home : /home/jane mail : sdbox:~/sdbox plugins : sieve quota_rule: *:storage=150M It seems to be nice, however I never got this only: ~# doveadm user lgb@office userdb: lgb@office That's all. The dovecot test configuration works otherwise via IMAP/POP3/LMTP nicely. What I guess that the lack of extra information (which would be needed by some scripts of mine, eg for getting user's home easily from shell scripts, as it's hash based, etc) is caused because I don't pass home (and/or other settings) back from userdb and/or passdb. However I do have these in global scope: mail_home = /mailstorage/%Ld/%Ln (yes, this is not hashed at all at the momement but it will be soon) mail_location = maildir:~/Maildir mail_uid = vmail mail_gid = vmail (... and also some global quota stuffs configured in plugin section) Now, I am a bit confused: even with passdb/userdb does not return with user home or GID/UID, dovecot knows these in case of pop3/imap/lmtp access, since these information can be "composed" from those settings. But then, wouldn't it possible so "doveadm user" shows those as well, like lmtp/pop3/imap can resolve those too? Honestly, it's a bit redundant to put needed information into user and pass attrs in every dbs (I have some) when dovecot knows those otherwise ... If I interpret "doveadm user"'s goal wrong (it's just for userdb/passdb query tool nothing more), is there any tool which works in this config, displaying extra information (at least user's home), or should I create some script which just repeats the functionality of dovecot's configured mail_home resolution? Thanks.

Hello, i'm trying to search in mails which are in russian language. Search works fine for UTF-8 mails, but it ignores KOI8-R ones. For english in any mails it also works fine. How i can solve it? I have dovecot 1.2.17 and following config for fts: protocol imap { ..... mail_plugins = quota imap_quota autocreate fts fts_squat } plugin { ... fts = squat fts_squat = partial=4 full=10 }

[Dovecot] Mail logger question
by Hungerburg 21 Jan '13

21 Jan '13

I use Dovecot simply as a way, to provide an e-mail archive for people on the LAN, where they can move messages into from within thunderbird. Mails are stored in a maildir of one system user where all the people know the password of. This was very easy to setup in ubuntu 12. Today I started using the mail_log plugin to provide an audit trail. Now I am looking for a light way, to get the log reflect the different people or principals. One way is, to create users with the same ID in the passwd and shadow files, but I'd rather have them in a separate file, something like a list of aliases for the system user. Can you suggest a simple way, without going virtual users? Below the relevant info on dovecot: $ dovecot --version 2.0.19 $ dovecot -n # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-35-generic x86_64 Ubuntu 12.04.1 LTS mail_plugins = " fts fts_squat mail_log notify" passdb { driver = pam } plugin { fts = squat fts_squat = partial=4 full=10 mail_log_events = save delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size from subject } protocols = " imap" ssl_cert = </etc/ssl/certs/ssl-cert-snakeoil.pem ssl_key = </etc/ssl/private/ssl-cert-snakeoil.key userdb { driver = passwd } Thank you all -- peter

[Dovecot] %d in configuration file does not work
by Jens Tobiska 19 Jan '13

19 Jan '13

I am trying to set up dovecot in a postfix virtual account/domains setting. In the configuration file I would like to use %d in two places, for: mail_location = /var/mail/vhosts/%d/%n and to specify the location of the respective passwd file: passdb passwd-file { args = /etc/auth/%d/shadow } Looking at the logs, %d is empty while %n works, so dovecot is looking for something in /var/mail/vhosts//myname and /etc/auth//shadow which don't exist. Replacing %d in dovecot.conf with the actual domain name works. So, the quesiton is, why is %d empty, and from where does it take its value?

[Dovecot] [PATCH] LMTP: Permit user IDs containing recipient_delimiter
by Ulrich Zehl 18 Jan '13

18 Jan '13

The Dovecot 2.1 LMTP server currently always strips the address extension from a recipient address (if recipient_delimiter is set), meaning user IDs cannot contain the recipient delimiter character, e.g. "user+foo" is not supported. This was surprising for me, as Postfix behaves differently in this regard: It first looks up "user+foo", and only then "user". The attached patch works for me and brings Dovecot's behavior in line with Postfix. Please let me know what you think about it.

[Dovecot] users = virual + system (both with ldap backend) => Fatal: setgid(12(mail)) failed with euid=501(...
by lejeczek 18 Jan '13

dear all probably something trivial, just cannot get my way around it, my goal is to get sieve on local-system users too, so postfix hands lda over to dovecot errors with mail for system users: lda(me): Fatal: setgid(12(mail)) failed with euid=501(me), gid=513(Domain Users), egid=513( Domain Users): Operation not permitted (This binary should probably be called with process group set to 12(mail) instead of 513(Doma in Users)) mail storage is in users' homes and these are on nfs3 which bits am I missing, please advise? regards

[Dovecot] possible: two private namespaces with different quota?
by Steffen Kaiser 17 Jan '13

17 Jan '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, in thread "how to setup different quota for multiple namespaces" I tried to get an additional, private namespace "archive" with yet another quota. Every message, regardless if delivered to INBOX or archive, counts for both namespaces, the default one and the archive one. Furthermore the dict records the quota of the archive namespace as user "ns=archive". Because the quota_rules does not accept "*", I see no way to have two or more private quota roots. Could one improve quota_root_rule_find(struct quota_root_settings *root_set, const char *name) { struct quota_rule *rule; array_foreach_modifiable(&root_set->rules, rule) { char *p = strchr(rule->mailbox_name, '\0'); if(p && p > rule->mailbox_name + 1 && p[-1] == '*' ) { /* compare box* */ if(memcmp(rule->mailbox_name, name, p - rule->mailbox_name - 2) == 0) return rule; } else if (strcmp(rule->mailbox_name, name) == 0) return rule; } return NULL; } So one could add a relative rule for the default private namespace.

[Dovecot] Benchmarking: Dovecot vs Courier. Courier wins as POP3 server
by Alexandr Sabitov 17 Jan '13

17 Jan '13

Hi All, I have compared Dovecot performance to Courier and it appears that as a POP3 server Dovecot is slower in 2 times but as an IMAP server it is faster in 1.5 times. The same node (16CPUs), testing time is 30 min, please see results and dovecot configs attached. Benchmark software is MStone used by Sendmail Inc so is is quite reliable. I do not see anything else to tweak in Dovecot to increase POP3 performance. Can we all have some tips to improve it please ? This is how my Dovecot set up: (LDAP user) -> Dovecot Director -> (Master user) -> Dovecot Dovecot Director: dovecot-shared-4:~# /usr/local/dovecot/bin/doveconf -n -c /usr/local/dovecot/etc/dovecot/dovecot-proxy.conf # 2.1.12: /usr/local/dovecot/etc/dovecot/dovecot-proxy.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.6 auth_debug = yes auth_mechanisms = plain login cram-md5 ntlm auth_verbose = yes base_dir = /var/run/dovecot-proxy default_internal_user = webmail director_mail_servers = 192.168.100.102 director_servers = 192.168.100.101 disable_plaintext_auth = no doveadm_password = blah doveadm_proxy_port = 9292 instance_name = dovecot-proxy listen = 192.168.100.101 log_path = /var/log/dovecot-proxy.log login_greeting = Dovecot Proxy ready. mail_location = maildir:~/ passdb { args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } service auth-worker { user = webmail } service auth { client_limit = 2400 } service director { fifo_listener login/proxy-notify { mode = 0666 } inet_listener { port = 9191 } unix_listener director-userdb { mode = 0600 } unix_listener login/director { mode = 0666 } } service doveadm { inet_listener { port = 9292 } } service imap-login { executable = imap-login director inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } service imap { service_count = 0 } service lmtp { inet_listener lmtp { port = 24 } } service pop3-login { executable = pop3-login director inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } } service pop3 { service_count = 0 } ssl_cert = </usr/local/dovecot/ssl/dovecot.pem ssl_key = </usr/local/dovecot/ssl/dovecot.pem userdb { args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol imap { mail_max_userip_connections = 100 } protocol doveadm { auth_socket_path = director-userdb } Dovecot (back-end): dovecot-shared-4:~# /usr/local/dovecot/bin/doveconf -n # 2.1.12: /usr/local/dovecot/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.6 auth_debug = yes auth_master_user_separator = * auth_mechanisms = plain login auth_verbose = yes base_dir = /var/run/dovecot/ default_internal_user = webmail disable_plaintext_auth = no doveadm_password = blah listen = 192.168.100.102 log_path = /var/log/dovecot.log mail_fsync = always mail_location = maildir:~/ mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = " quota fts fts_lucene" mmap_disable = yes namespace { inbox = yes location = prefix = INBOX. separator = . } passdb { args = /usr/local/dovecot/etc/dovecot/passwd.masterusers driver = passwd-file master = yes pass = yes } passdb { driver = static } plugin { fts = lucene fts_lucene = whitespace_chars=@. quota = maildir:User quota } service director { unix_listener director-admin { mode = 00 } } service doveadm { inet_listener { port = 9292 } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } process_limit = 20 process_min_avail = 8 } service imap-postlogin { executable = script-login /usr/local/dovecot/bin/imap-postlogin.sh user = webmail } service imap { executable = imap imap-postlogin } service lmtp { inet_listener lmtp { port = 24 } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } process_limit = 20 process_min_avail = 8 } service pop3-postlogin { executable = script-login /usr/local/dovecot/bin/pop3-postlogin.sh user = webmail } service pop3 { executable = pop3 pop3-postlogin } ssl_cert = </usr/local/dovecot/ssl/dovecot.pem ssl_key = </usr/local/dovecot/ssl/dovecot.pem userdb { args = /usr/local/dovecot/etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol imap { mail_plugins = " quota fts fts_lucene imap_quota" } Best Regards, Alexandr Sabitov Netregistry
