[Dovecot] dovecot 2.1.12 panic in mbox-sync.c

Hello! I use dovecot 2.1.12 locally on a 32bit Linux with an ext4 filesystem and after deleting a lot of emails from a mbox folder, I now get the following messages in the log: dovecot: imap(amied): Panic: file mbox-sync.c: line 1351 (mbox_sync_handle_eof_updates): assertion failed: (offset == 0 || offset > 31) dovecot: imap(amied): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x4559a) [0x6f68959a] -> /usr/lib/dovecot/libdovecot.so.0(+0x45611) [0x6f689611] -> /usr/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x6f658fa0] -> /usr/lib/dovecot/libdovecot-storage.so.0(+0x2d707) [0x6f708707] -> /usr/lib/dovecot/libdovecot-storage.so.0(mbox_sync+0x53) [0x6f7091d3] -> /usr/lib/dovecot/libdovecot-storage.so.0(mbox_storage_sync_init+0x6d) [0x6f70936d] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_sync_init+0x3b) [0x6f72333b] -> /usr/lib/dovecot/libdovecot-storage.so.0(mailbox_sync+0x3f) [0x6f72347f] -> dovecot/imap(cmd_select_full+0x16b) [0x805529b] -> dovecot/imap(cmd_select+0x17) [0x8055c57] -> dovecot/imap(command_exec+0x32) [0x80596f2] -> dovecot/imap() [0x80586fd] -> dovecot/imap() [0x805880d] -> dovecot/imap(client_handle_input+0x125) [0x8058a05] -> dovecot/imap(client_input+0x60) [0x80592f0] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x44) [0x6f6981f4] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xce) [0x6f6991ce] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x40) [0x6f697cd0] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x2e) [0x6f680dbe] -> dovecot/imap(main+0x279) [0x804fdd9] -> /lib/libc.so.6(__libc_start_main+0xf5) [0x6f49bad5] -> dovecot/imap() [0x804ff51] The mbox file seems to be unchanged and a .lock file remains even after stopping dovecot.

I'm preparing to set up a new set of directors on dovecot-ee-2.1.10.3-1, but would prefer to do this a bit gradually. Will it be OK to set up a ring of directors with 2x dovecot-ee-2.1.10.3-1 and 2x dovecot-2.0.14 ? -jf

[Dovecot] dovecot testinstallation does not tell how to quit
by Robert Moskowitz 28 Dec '12

28 Dec '12

I am having problems logging in with RoundCube, so thought I should see if there were instructions for testing Dovecot login, and sure enough I found some at: wiki.dovecot.org/Testinstallation Well it works, so the problem is probably all RoundCube's, but this wiki page is missing an important line about how to end the Telnet session without killing Telnet! What is the quit/exit command? And please add this to the wiki! Oh, I just guessed it: a logout

[Dovecot] Using -module flag on sieve libs
by Dimitri 26 Dec '12

26 Dec '12

Some modern distros (Mageia, Mandriva) use -no-undefined as a default linker flag for building software. However, undefined symbols are OK if the binary being linked is a plugin. To detect plugins, build system looks for presence of "-module" libtool flag in makefiles. There are two libraries in Pigeonhole that couldn't be linked with -no-undefined: src/lib-sieve/plugins/mailbox/libsieve_ext_mailbox.la src/lib-sieve/libdovecot-sieve.la These modules do contain undefined symbols, but they are not linked against library that provides them. It would be good if corresponding makefiles contained "-module" flags, so that build system could selectively turn off that -no-undefined linker flag. Please see proposed patch (attached). Thanks, Dimitri Mageia Linux packager

[Dovecot] Postfix/mysql/dovecot - Understanding password encryption
by Robert Moskowitz 25 Dec '12

25 Dec '12

I am switching from a fedora/postfix/mysql/couriermail/squirrelmail to Centos/.../dovecot/roundcubemail and adding postfixadmin to the mix. My tutorial before was an earlier version (on F14) of: http://www.howtoforge.com/virtual-users-and-domains-with-postfix-courier-my… Now I am using http://www.campworld.net/thewiki/pmwiki.php/LinuxServersCentOS/Cent6VirtMai… to get me started. I am up to roundcubemail setup and am stumbling to understand what the author here is doing with encrypted passwords, so felt it was time to delve deeper into this. My old setup uses mysql-crypt for the password. MYSQL_CRYPT_PWFIELD password and users could be added to the table with: INSERT INTO `users` (`email`, `password`, `quota`) VALUES ('sales(a)example.com', ENCRYPT('secret'), 10485760); But where this was all simple and no choices, I get to figure out what to do with my dovecot setup. Some of the 'secret' is hinted at in postfixadmin's config.inc.php: // Encrypt // In what way do you want the passwords to be crypted? // md5crypt = internal postfix admin md5 // md5 = md5 sum of the password // system = whatever you have set as your PHP system default // cleartext = clear text passwords (ouch!) // mysql_encrypt = useful for PAM integration // authlib = support for courier-authlib style passwords // dovecot:CRYPT-METHOD = use dovecotpw -s 'CRYPT-METHOD'. Example: dovecot:CRAM-MD5 $CONF['encrypt'] = 'md5crypt'; Where is there information on the different choices and how to choose. Is it as 'simple' as setting up postfixadmin to control the password encryption format then 'inform' dovecot in the dovecot-mysql.conf with default_pass_scheme = MD5-CRYPT Thank you for any pointers.

[Dovecot] Understanding Sockets
by Tim Smith 22 Dec '12

22 Dec '12

Hi, Just trying to consolidate my knowledge of Dovecot and I want to understand various things rather than just key out lines of config in dovecot.conf with the hope of it working. What I wanted to clarify is my understanding the "socket listen" section of the config file. From my limited understanding, this section details how other processes can access the userdb defined in Dovecot. The master socket is used for "internal" processes which is mainly dovecot-lda so that when Dovecot receives mail it knows where to deliver it and client is defined for "external" processes, for example Postfix who would use the info to determine if a user existed. Would you say this is a fair (albeit) dumbed down!!) synopsis of sockets and their purpose? Thanks in advance! Tim

[Dovecot] Non-dovecot user looking for feedback
by Chris Ross 21 Dec '12

21 Dec '12

I've been using UW-IMAPd for neigh on forever (at least since 2001). But, as it's basically stalled, and I'm about to update the hardware that is my mail server, I thought it was time to review existing open-source IMAP servers. Dovecot is the top three in my looking. The other of the top three candidates, because I know of people who've used it, is Cyrus IMAP. So, I should note that my thoughts are "uw-imapd, because I already know how to use it", "Cyrus, because someone I know/trust liked it years ago", and dovecot, because "it seems stable, professional, and to meet all of my needs". I guess the biggest question I have is how files/folders are stored in the filesystem. uw-imapd has a "mbx" format that all of my folders are in, and also has support for mbox and maildir (i think). mbx had some advantages for speed access, which would be unimportant I assume with dovecot's indexes, but IIRC there was also some reason the mbox format coped poorly with multiple clients accessing the same folder at the same time. So, am I right that dovecot supports only the "one big full file" mbox format, and the maildir format? And if so, is it known to allow multiple simultaneous IMAP clients to access and monitor and/or modify the same folder simultaneously? After those questions, it's just a "what do you think the pros and cons of each are?" I know asking in this forum, that I will get most if not all votes for Dovecot. And that's fine, as long as you have specific reasons why it would be better for someone with only a handful of users and minimal time available to administer the systems in question. Thanks! I appreciate any and all feedback. - Chris

[Dovecot] backtrace from postgres dict
by Steffen Kaiser 20 Dec '12

20 Dec '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, since I enabled ACLs I get following backtrace. It looks like that it happens if the ACLs had been changed only. Also, it looks like that it always happens 1 minute after last "dict: Info: pgsql(localhost): Connected to database dovecot", no matter if the user is logged in (and idle) or logged off. Postgres logs: "could not receive data from client: Connection reset by peer" and "unexpected EOF on client connection". Is there some TCP keep alive issue? Postgres is using the "system default" for TCP keep alive. I'm currently testing ACLs via telnet, so the activity with the ACL dict is pretty low, hence, an idle timeout would make much sense. # ../../sbin/dovecot --version 2.1.10 (a4f02f6c0d32) dict connect string: connect = host=localhost dbname=db user=user 2012-11-28 10:03:39 dict: Info: pgsql(localhost): Connected to database dovecot 2012-11-28 10:03:39 dict: Info: pgsql(localhost): Connected to database dovecot 2012-11-28 10:03:39 dict: Info: pgsql(localhost): Connected to database dovecot 2012-11-28 10:03:58 IMAP(user) [22922]: Info: Disconnected: Logged out in=23 out=763 2012-11-28 10:04:41 dict: Panic: file driver-pgsql.c: line 84 (driver_pgsql_set_state): assertion failed: (state == SQL_DB_STATE_BUSY || db->cur_result == NULL) 2012-11-28 10:04:41 dict: Error: Raw backtrace: /usr/local/dovecot-2.1.10/lib/dovecot/libdovecot.so.0(+0x4857a) [0x7f91f511157a] -> /usr/local/dovecot-2.1.10/lib/dovecot/libdovecot.so.0(+0x485c6) [0x7f91f51115c6] -> /usr/local/dovecot-2.1.10/lib/dovecot/libdovecot.so.0(i_error+0) [0x7f91f50e4eaf] -> dovecot2.1/dict() [0x40aa36] -> dovecot2.1/dict() [0x40aa91] -> dovecot2.1/dict() [0x40bed3] -> dovecot2.1/dict() [0x409504] - -> dovecot2.1/dict(sql_db_cache_deinit+0x20) [0x408a60] -> dovecot2.1/dict(main+0x169) [0x405a59] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7f91f4b5cc8d] -> dovecot2.1/dict() [0x404bb9] 2012-11-28 10:04:41 dict: Fatal: master: service(dict): child 22923 killed with signal 6 (core not dumped) - -- Steffen Kaiser -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEVAwUBULXbiGoxLS8a3A9mAQI9Ywf/YItPO4fFT70HcuwCkDXgx0Sn7CEyXu2j +1VzOu3R/TMs1rcxYJIvWiei6Nk3wXywzQl84POadJn61Yf2NuT80nMxwBsBbgio e+0oRE9JNVSjtvX5l7kehEdUDQjqRRKyrhWG9KDlpjWidGsYh7pQg0rDtp3UwG57 HuSBMiBAZ9t9sC2DXjn9wT9vweH3gMIhc/K5U0BLF5JG/K8UAKc5QBUgezjIYzvn KP90TJ4RoZ2vnPzmWfeIsjffRBvvC6UUgWmU02e2H9xJxzF32Nix0s8YWi7G91sH Ei057HW5NsKNDtp6B5fYk+xCpC6ucQiwFSr/ZG+uZCAdtTd2qmf60g== =tQYK -----END PGP SIGNATURE-----

[Dovecot] setting mail_home and vacation

20 Dec '12

Hello! dovecot version 2.1.7 I set up vacation with sieve. We have mboxes and maildirs and in dovecot.conf mail_location = mbox:/var/spool/vhosts/%d/dovecotprivate/%n:INBOX=/var/spool/vhosts/%d/%n Error: User archiv(a)xyz.de doesn't have home dir set, disabling duplicate database Dec 19 20:37:03 lda(archiv(a)xyz.de): Error: sieve: sieve script file path ~/.dovecot.sieve is relative to home directory, but home directory is not available. Dec 19 20:37:03 lda(archiv(a)xyz.de): Error: sieve: failed to access user's sieve script ~/.dovecot.sieve (using default script location instead) When I set mail_home = mbox:/var/spool/vhosts/%d/%n:INBOX=/var/spool/vhosts/%d/%n I get this for mboxes in the log: Error: user archiv(a)xyz.de: Relative home directory paths not supported: mbox:/var/spool/vhosts/xyz.de/archiv:INBOX=/var/spool/vhosts/xyz.de/archiv The .dovecot.sieve script of the user seems to be found, a vacation response is sent and the email is stored mail into mailbox 'INBOX' What is wrong?

[Dovecot] Problems trying to add dspam delivery to dovecot LDA to working Postfix/Dovecot server. No passdb.
by Brian Jarrett 20 Dec '12

20 Dec '12

Hello list, I'm really hoping someone can point me in the right direction on this. I set up a server using Postfix with LDAP lookups to Active Directory. Postfix delivers to maildir. Dovecot IMAP and POP are working correctly using PAM Kerberos to authenticate via Active Directory. I want to add spam filtering, so I'm trying to set up Postfix to use dspam which is then supposed to use Dovecot LDA to deliver messages to the mailbox instead of having Postfix deliver to the Maildir. I can't get any deliveries to Dovecot LDA to get past passdb lookup. When I run /usr/lib/dovecot/deliver -f bjarrett(a)garfield16.org -d bjarrett(a)metcalfexcavation.com I get: Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: master in: USER#0111# 011bjarrett(a)metcalfexcavation.com#011service=lda Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: password( bjarrett(a)metcalfexcavation.com) passdb doesn't support credential lookups Dec 19 20:57:55 mxserver2 dovecot: auth: Error: static( bjarrett(a)metcalfexcavation.com) passdb doesn't support lookups, can't verify user's existence Dec 19 20:57:55 mxserver2 dovecot: auth: Debug: master out: FAIL#0111 Dec 19 20:57:55 mxserver2 dovecot: lda: Error: user bjarrett(a)metcalfexcavation.com: Auth USER lookup failed Dec 19 20:57:55 mxserver2 dovecot: lda: Fatal: Internal error occurred.

[Dovecot] Maildir hardlinks with sieve
by Benedetto Vassallo 19 Dec '12

19 Dec '12

Hi all, First of all, excuse me for my previous posts (Maildir hardlinks). Today I realized the following issue. Maildir hardlinks works OK on dovecot 2.1.10 without sieve. If set sieve plugin in dovecot-lmtp hardlinks stop working. Is there a way to have both sieve and hardlinks working?

[Dovecot] namespace subscription problem
by Holger Hegmanns 19 Dec '12

19 Dec '12

Hi all, my problem seems to be a cosmetic one (again). According to the docs: subscriptions: "yes" (default) if this namespace should handle its own subscriptions. If "no", then the first parent namespace with subscriptions=yes will handle it. Therefore is no way to create the following scenario: three namespaces (private, shared, public) the private namespace has to handle its own subscriptions the private namespace setup with "prefix = INBOX." the both shared and public namespace setup with "subscriptions = no" cause there is no so called "parent" namespace. Private namespace setup with "prefix = " works fine, but that's not what I want. namespace { type = public separator = . prefix = public. location = maildir:/var/spool/dovecot/vmail/public subscriptions = no } namespace inbox { type = private separator = . prefix = INBOX. inbox = yes } namespace { type = shared separator = . prefix = user.%%u. location = maildir:%%h/Maildir:INDEX=~/Maildir/shared/%%u subscriptions = no list = children } Any chance that the private namespace can subscribe to shared mailboxes with the principals above? ... Few hours later. Added a default namespace without any prefix: namespace { prefix = separator = . hidden = yes subscriptions = yes } Subscriptions works as expected, but when I telnet to dovecot now the LSUB command shows all boxes beneath the INBOX as well as without the prefix: b lsub "" * * LSUB () "." "Sent" * LSUB () "." "Templates" * LSUB () "." "Trash" * LSUB () "." "Drafts" * LSUB () "." "INBOX.Sent" * LSUB () "." "INBOX.Templates" * LSUB () "." "INBOX.Trash" * LSUB () "." "INBOX.Drafts" * LSUB () "." "INBOX.user.bar.Sent" * LSUB () "." "user.bar.Sent" b OK Lsub completed. Completely stuck Holgert

[Dovecot] migration to dovecot pop3
by Rajesh M 19 Dec '12

19 Dec '12

hi i am planning to migrate from qmail pop3 to dovecot pop3 the number of users on the server is large over 5000 also data volume is large - over 3.5 tb -- ie many users several 1000s of emails in their inbox email clients used are outlook / outlook express / windows mail, etc my questions 1) will the migration cause all the emails on the server to re-download 2) can dovecot be configured to allow only one download at a time - pop3 locking with time out setting that can be customized 3) can dovecot pop3 be configured so that it will allow download of emails only of the last say 15 days ie even if the same pop3 user is configure on another machine it will download only messages of the last 15 days 4) has anybody migrated from qmail pop3 to dovecot pop3 successfully without emails being downloaded again thankyou very much in advance rajesh

[Dovecot] Upload / migrate old mails: iPhone shows oldest mails first
by Denny Schierz 19 Dec '12

19 Dec '12

hi, I've got a very strange behavior: I uploaded old mails from a local folder (thunderbird / osx) to my Dovecot (Debian Squeeze) and now, the iphone (ios6) show the oldest mails first. The only thing I can imagine is, that Dovecot got from Thunderbird the newest mails first and last the old mails, so that in the last mdbox are the old one. So, if it is correct, how can I fix it? cu denny
