[Dovecot] Quota
by Josh Kelley 14 Jun '05

14 Jun '05

We're getting ready to set up a new mail server running dovecot 0.99.11 (CentOS 4) with maildir and filesystem quotas. I saw on the Dovecot web site that "hard filesystem quota can also be problematic." How problematic? What problems might we anticipate? Thanks. Josh Kelley

[Dovecot] Can't see existing mail folders
by Chris Green 14 Jun '05

14 Jun '05

I have installed dovecot version 0.99.11 on my Slackware 10.1 system recently and it basically works as expected. However I can't get it to 'see' existing mbox hierarchies. I have the following in dovecot.conf:- default_mail_env = mbox:/home/%u/Mail:INBOX=/var/mail/%u (I also originally tried with %h/Mail) IMAP MUAs can see the INBOX OK but I can't get them to see any of the mail in $HOME/Mail. There certainly is lots of mail there, 250Mb or so of it, and a local mutt can see it without problems. Am I missing something obvious or will dovecot only see mail and folders that it's created itself? -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."

dovecot: Jun 11 23:57:56 Info: auth(default): pam(testi(a)irkkaa.net,83.145.196.129): pam_authenticate() failed: Authentication failure tried also debugging whats wrong with it, it queries ok, the password in the query is ok and everything. but it never replies +OK. that connection just halts after PASS command. Tried IMAP, same result. config: (dovecot.conf, PLAIN etc all enabled) passdb pam { args = * } passdb sql { args = /usr/local/etc/dovecot-mysql.conf } userdb passwd { } userdb sql { args = /usr/local/etc/dovecot-mysql.conf } default_pass_scheme = PLAIN password_query = SELECT username as user, password FROM mailbox WHERE username = '%u' user_query = SELECT concat('/usr/local/virtual/',maildir) as home, 207 AS uid,208 AS gid FROM mailbox WHERE username = '%u' postfixadmin-format mysql-DB, mails in /usr/local/virtual/user@domain/Maildir Any ideas where stuff could go wrong? Passwords in the MySQL are cleartext and checked that query returns right values. Yet authentication-phase just gets stuck. System is hardned Gentoo-Linux (2.6.11r13-grsec)

[Dovecot] Question regarding dovecot 0.99.14 & 1.0 stable
by Sebastiaan de Vogel 14 Jun '05

14 Jun '05

Hi all, For several day's now I've been attempting to get Dovecot working, but without much success so far. I've compiled both 0.99.14 and the latest 1.0 stable version with mysql support, which seems to be working for the 0.99.14. Unfortunately version 1.0 stable wont start and quits with this: dovecot: Jun 13 16:44:47 Error: child 27346 (auth) killed with signal 11 dovecot: Jun 13 16:44:48 Error: Auth process died too early - shutting down Version 0.99.14 starts though! I've not included my dovecot.conf and dovecot-mysql conf here because of their size, if you need them please ask me by email. This version seems to work, I can see the databse getting queried, and can get authenticated. After authentication it just says this: dovecot-auth: Jun 13 19:16:49 Info: MySQL: Performing query: SELECT clear FROM users,domains WHERE users.username = 'sebastiaan(a)**.**' AND users.enabled = '1' AND users.type='local' and domains.enabled='1' and domains.domain_id = users.domain_id; dovecot-auth: Jun 13 19:16:49 Info: MySQL: Performing query: SELECT maildir||'/sebastiaan' as home, uid, gid FROM domains WHERE domain = '**.**'; pop3-login: Jun 13 19:16:49 Info: Internal login failure: sebastiaan(a)**.** [**.**.215.237] dovecot-auth: Jun 13 19:16:49 Info: MySQL: connected to localhost dovecot-auth: Jun 13 19:16:49 Info: Login process 8 connected dovecot-auth: Jun 13 19:16:49 Info: Login process 8 sent handshake: PID 15133 dovecot-auth: Jun 13 19:16:49 Info: Login process 9 connected dovecot-auth: Jun 13 19:16:49 Info: Login process 9 sent handshake: PID 15149 dovecot-auth: Jun 13 19:16:49 Info: Login process 10 connected dovecot-auth: Jun 13 19:16:49 Info: Login process 10 sent handshake: PID 15124 dovecot-auth: Jun 13 19:16:49 Info: Login process 11 connected dovecot-auth: Jun 13 19:16:49 Info: Login process 11 sent handshake: PID 15126 dovecot-auth: Jun 13 19:16:49 Info: Login process 12 connected dovecot-auth: Jun 13 19:16:49 Info: Login process 12 sent handshake: PID 15127 dovecot-auth: Jun 13 19:16:49 Info: Login process 13 connected dovecot-auth: Jun 13 19:16:49 Info: Login process 13 sent handshake: PID 15129 The client gets disconnected and just says this: +OK dovecot ready. user sebastiaan(a)**.** +OK pass blabla +OK Logged in. BYE Internal login failure. Error report written to server log. Does anyone have any suggestions to get Dovecot to work please? Thanks in advance Sebastiaan

[Dovecot] chroot directory question
by Lisa C Boyd 14 Jun '05

14 Jun '05

I am setting up dovecot for imap on a new Fedora 3 box. Through SquirrelMail I can access my email - no problem. However my other users are getting this error message: ERROR : Connection dropped by imap-server. Query: CAPABILITY Looking in the maillog file for further error details gives me this: dovecot: chroot directory no included in valid_chroot_dirs: /home/user Looking through the dovecot.conf file I see where it says not to add in home directories under valid_chroot_dirs if the users have access to those directories. So I'm stuck now as to what I need to add to the conf file and I'm a little confused as to why it works for my email account and not the other users. Everything with these user accounts is setup the same (same maildir format, etc.). Thanks for any help :) Lisa B.

[Dovecot] Mailbox usage

I use dovecot-0.99.11 from RHEL4. dovecot-mysql.conf: === db_host = dbhost db_port = 3306 db = db db_user = dovecot db_passwd = pass default_pass_scheme = PLAIN password_query = SELECT password FROM users WHERE username = '%u' user_query = select maildir AS home,u_id AS uid,g_id AS gid from users WHERE username = '%u' === When I try "telnet localhost 110" and enter test login, I get in errorlog: === dovecot-auth: Jun 06 07:21:49 Info: MySQL: Performing query: SELECT password FROM users WHERE username = 'andy@domain' dovecot-auth: Jun 06 07:21:49 Info: MySQL: Performing query: select maildir AS home,u_id AS uid,g_id AS gid from users WHERE username = 'andy@domain' pop3-login: Jun 06 07:21:49 Info: Login: andy@domain [::ffff:127.0.0.1] dovecot-auth: Jun 06 07:21:49 Info: Login process 9 disconnected dovecot: Jun 06 07:21:49 Fatal: chdir(/var/mail-domain/andy@domain) failed with uid 506: Not a directory dovecot: Jun 06 07:21:49 Error: child 19446 (pop3) returned error 89 === I think, dovecot use "/var/mail-domain/andy@domain" as maildir - not as mailbox. What need set in dovecot config for work with mailbox? Thanks. -- Best regards, Andrew Velikoredchanin

[Dovecot] Debugging test72
by Doug Luce 14 Jun '05

14 Jun '05

When attempting to save a message from the INBOX to a folder in a collection (like, .projects.dovecot), I get behavior like this (in GDB). Any clue what might be going wrong? Here's where a SIGABRT happens: 280 return array->buffer->used / array->element_size; This is the stack trace: (gdb) where #0 mail_index_map_get_ext_idx (map=0x1200c0db0, ext_id=0, idx_r=0x11ffe828) at ../../src/lib/array.h:280 #1 0x120058dcc in _view_lookup_ext_full (view=0x1200c0db0, seq=0, ext_id=0, map_r=0x11ffe898, data_r=0x11ffe8a0) at mail-index-view.c:395 #2 0x120059468 in mail_index_lookup_ext_full (view=0x1301100d4, seq=0, ext_id=301983784, map_r=0x1300e2078, data_r=0x1200c4f14) at mail-index-view.c:561 #3 0x12005912c in mail_index_lookup_keywords (view=0x1200c4e00, seq=0, keyword_idx=0x11ffe8f8) at mail-index-view.c:475 #4 0x12003e880 in index_mail_get_keywords (_mail=0x1200c0db0) at index-mail.c:184 #5 0x120063238 in mail_get_keywords (mail=0x1301100d4) at mail.c:39 #6 0x120063550 in mail_storage_copy (t=0x1200c2880, mail=0x1200e7020, dest_mail=0x0) at mail-copy.c:22 #7 0x12002a90c in maildir_copy (_t=0x1200c2880, mail=0x1200e7020, dest_mail=0x0) at maildir-copy.c:155 #8 0x120064dac in mailbox_copy (t=0x1301100d4, mail=0x0, dest_mail=0x11ffe828) at mail-storage.c:456 #9 0x120011b78 in fetch_and_copy (t=0x1200c2880, srcbox=0x0, search_args=0x1200e7020) at cmd-copy.c:28 #10 0x120011d98 in cmd_copy (cmd=0x1200c0268) at cmd-copy.c:88 #11 0x120017598 in client_handle_input (cmd=0x1200c0268) at client.c:334 #12 0x120017748 in _client_input (context=0x1200c0db0) at client.c:383 #13 0x12007e670 in io_loop_handler_run (ioloop=0x1200c2000) at ioloop-poll.c:184 #14 0x12007dd5c in io_loop_run (ioloop=0x1200c2000) at ioloop.c:218 #15 0x120022b10 in main (argc=537660848, argv=0x11ffeb10, envp=0x11ffeb20) at main.c:228 And, stepping from this position results in the bomb: (gdb) s Program received signal SIGABRT, Aborted. 0x130247908 in kill () from /lib/libc.so.5 I'm not too familiar with the source code, so figuring out exactly what this is up to would be a major chore. I'm hoping someone can give me a little clue as to what direction I should take to fix this problem. Thanks! Doug

[Dovecot] assertion failed -0.99 -> 1.0-stable
by Thomas Hummel 14 Jun '05

14 Jun '05

Hello Timo, I've upgraded from dovecot-0.99 to dovecot-1.0-stable (the 2005-05-09 version) on FreeBSD 5.4 and encountered the following problems (problem #4 (assertion failed) made me downgrade back to dovecot-0.99...) : 1. mbox sync: UID inserted in the middle of mailbox /var/mail/gopauld (5230 > 4407) --> OK, that's documented on the Wiki, not a real problem 2. imap(cxxx): mkdir_parents(/opt/dovecot/c/cxxx/.imap/INBOX) failed: Permission denied --> I can't understand why since /opt/dovecot/c is rwxrwxrwt and belongs to root:wheel 3. dovecot: IMAP(xxxx): UIDs broken with partial sync in mbox file /yyyy/zzzz/xxxx/Mail/Drafts 4. dovecot: IMAP(xxxx): file istream-raw-mbox.c: line 383 (istream_raw_mbox_get_body_size): assertion failed: +(rstream->body_offset != (uoff_t)-1) --> That one occured each time a user connected with Eudora (on OS-X) moved messages from INBOX to some of her IMAP mailboxes. Since it was in real life, I hadn't time to get a gdb backtrace. Notes : . that user had restarted her client (Eudora). . my messages moves from one IMAP mbox to another did work. . the assertion failed occured with the version of 2005-06-04 as well (which I tried since the ChangLog mentionned some similar problems). Any clues ? -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

Is the CONTROLDIR directive only available (undocumented as it may be) in the 1.0 series? I'm currently using 0.99.13 and I didn't find CONTROLDIR with grep. Thanks alan
