[Dovecot] Intermittent "Password Mismatch" errors
by dan＠ipws.com 03 Jan '06

03 Jan '06

Hello - I have had a problem the last few days with Dovecot reporting intermittent "Password Mismatch" errors for pretty much every client. Not all the time, maybe 1 out of every 10 connections. I cannot pinpoint where the process may be failing. I am using a MySQL backend to store user information in, and Dovecot queries that database directly. It works fine, but it seems as if Dovecot has a problem connecting to the SQL server for this information, instead of doing something smart, it just reports a password mismatch. I've turned on debugging and verbose logging, but I can't see exactly *why* the process fails on occasion. MySQL is tuned appropriately, and there's no reason why Dovecot cannot connect to the server. I'm wondering if anyone has seen this, and if so, what they've done about it. Because honestly, I'm lost. Thanks -dant

[Dovecot] very slow imap opens in pine after moving maildirs to new drive
by Dave Lugo 03 Jan '06

03 Jan '06

Hi, I've been running dovecot-0.99.10 for the past several years, with virtually no problems. Lately, I noticed that the filesystem holding my users' imap maildirs was getting close to full. So... last night, I used tar to copy /var/spool/imap to a new drive (9G scsi, reiserfs) that I then mounted under /var/spool/imap (after moving the old dir aside). After the move, what would take pine a handful of seconds, with the load average barely breaking .40, now takes several minutes, with a load average spike to nearly 3. I must admit to being rather puzzled by this, as I would not have expected the move to result in worse performance. Do I need to figure out what the index file names are, and delete those? Any suggestions greatly appreciated - as even closing pine now takes nearly 5 minutes, whereas when dovecot talks to my old imap dir (I've tested this), closing the session takes no more than 10 seconds. server is Mandrake 9.1, 2.4.21-0.13mdkenterprise, P4 2.6GHz, 1G RAM 9G U2W SCSI system disk, 9G U2W SCSI (and big*ss IDE drive for /users). Each of the scsi drives is on its own aha-2940UW controller. Filesystem on old imap location (/var filesystem) is reiserfs, same as that on new dedicated disk.

[Dovecot] fast bind patch for ldap passwords
by Geff 03 Jan '06

03 Jan '06

All, I'm not sure if I sent this in yet or not. Basically it works like this: if you set "fast_bind = yes" it overrides auth_bind. And requires that you set userdn. Example config: fast_bind = yes userdn = cn=%u,ou=people,o=dovecot I'm using the patch right now on the cvs head branch. Comments are welcome. Geff

[Dovecot] another migration problem from courier with Outlook 2003
by Andreas Mimz 02 Jan '06

02 Jan '06

So I'm still trying to figure out a way to migrate from courier-imap to dovecot but I got stuck again... basically all of the clients are working now (more or less) - but when using outlook 2003 I don't see any email! the folders are there - just no emails! I think there's still a namespace problem somehow... I've attached the rawlog .in and .out files... when I select the Spam folder outlook tries to access "Posteingang.Spam" which should be "INBOX.Spam", shouldn't it?? my namespace config: namespace private { separator = . location = maildir:~/Maildir prefix=INBOX. inbox = yes hidden = no } maybe anyone can help me out?! thanks a lot! aexd IDLE DONE tgr8 LIST "" "" qqvt IDLE DONE nlvq LSUB "" "*" wjll STATUS "INBOX.Drafts" (UNSEEN) yhuw STATUS "INBOX.Gesendete Objekte" (UNSEEN) epjg STATUS "INBOX.Junk E-mail" (UNSEEN) r2bz STATUS "INBOX.Sent" (UNSEEN) 16iu STATUS "INBOX.Spam" (UNSEEN) 3vki STATUS "INBOX.Spam.Erkennungsfehler" (UNSEEN) dstc STATUS "INBOX.Spam.Erkennungsfehler.irrtuemlich Erkannt" (UNSEEN) 64bl STATUS "INBOX.Spam.Erkennungsfehler.nicht erkannt" (UNSEEN) gwa0 STATUS "INBOX.Spam.treffer" (UNSEEN) 31sy STATUS "INBOX.Spam.verdacht" (UNSEEN) u9fg STATUS "INBOX.Trash" (UNSEEN) dypb IDLE DONE 4u5q LIST "" "INBOX" x8nb LSUB "" "*" dja3 LIST "" "INBOX" x40b LSUB "" "*" eg5t IDLE DONE mj6l SELECT "Posteingang" uj7v IDLE DONE 7w1o SELECT "Posteingang.Spam" zuyg IDLE DONE xsoy SELECT "Posteingang" kiuz IDLE DONE dx73 LSUB "" "*" 4qnd STATUS "INBOX.Drafts" (UNSEEN) 61vj STATUS "INBOX.Gesendete Objekte" (UNSEEN) jhaw STATUS "INBOX.Junk E-mail" (UNSEEN) x7t3 STATUS "INBOX.Sent" (UNSEEN) gipp STATUS "INBOX.Spam" (UNSEEN) cx56 STATUS "INBOX.Spam.Erkennungsfehler" (UNSEEN) yw81 STATUS "INBOX.Spam.Erkennungsfehler.irrtuemlich Erkannt" (UNSEEN) nx8w STATUS "INBOX.Spam.Erkennungsfehler.nicht erkannt" (UNSEEN) 1nfc STATUS "INBOX.Spam.treffer" (UNSEEN) wf7r STATUS "INBOX.Spam.verdacht" (UNSEEN) 9y3i STATUS "INBOX.Trash" (UNSEEN) al6r IDLE DONE fcd9 LSUB "" "*" dpxa STATUS "INBOX.Drafts" (UNSEEN) 6fsv STATUS "INBOX.Gesendete Objekte" (UNSEEN) 8nyj STATUS "INBOX.Junk E-mail" (UNSEEN) lsnf STATUS "INBOX.Sent" (UNSEEN) gmym STATUS "INBOX.Spam" (UNSEEN) u7nd STATUS "INBOX.Spam.Erkennungsfehler" (UNSEEN) r8zi STATUS "INBOX.Spam.Erkennungsfehler.irrtuemlich Erkannt" (UNSEEN) hrja STATUS "INBOX.Spam.Erkennungsfehler.nicht erkannt" (UNSEEN) 9keb STATUS "INBOX.Spam.treffer" (UNSEEN) iwfc STATUS "INBOX.Spam.verdacht" (UNSEEN) 1pd6 STATUS "INBOX.Trash" (UNSEEN) bhfu IDLE * OK [RAWLOG TIMESTAMP] 2006-01-02 00:01:31 + idling aexd OK Idle completed. tgr8 OK List completed. + idling qqvt OK Idle completed. * LSUB () "."

[Dovecot] Using dovecot auth with Postfix
by Kim Culhan 01 Jan '06

01 Jan '06

Attempting to setup smtpd auth for Postfix using the Dovecot authorization unix socket. Some info is at: http://www.postfix.org/SASL_README.html To enable operation when Postfix is chrooted, a method from the reference above is to locate the socket at: /var/spool/postfix/private/auth To do this, I have this configuration in dovecot.conf: # listener sockets will be created by Dovecot's master process using the # settings given inside the auth section auth default_with_listener { mechanisms = plain passdb passwd { } userdb pam { } socket listen { master { path = /var/spool/postfix/private/dovecot-auth-master # WARNING: Giving untrusted users access to master socket may be a # security risk, don't give too wide permissions to it! mode = 0600 # Default user/group is the one who started dovecot-auth (root) user = group = } client { path = /var/spool/postfix/private/dovecot-auth-master mode = 0660 } } } With this configuration Dovecot writes this to the log at startup: dovecot: Dec 31 17:04:32 Error: child 3536 (auth) returned error 89 dovecot: Dec 31 17:25:34 Error: Auth process died too early - shutting down dovecot: Dec 31 17:25:34 Error: auth(default_with_listener): Unknown userdb driver 'pam' (typo, or Dovecot was built without support for it? Check with dovecot --build-options) Before modifying the setup for this auth function, pam authentication was working fine. Also, Dovecot will make /auth owned by root which Postfix considers a 'fatal' problem. Should it be setup to run as user Postfix ? Any help here is vy appreciated -kim -- w8hdkim(a)gmail.com

[Dovecot] invalid mbox files
by Harout S. Hedeshian 31 Dec '05

31 Dec '05

Hello! I recently upgraded from dovecot 0.9x to 1.0.5-Aplha and now when ever folders are opened (in IMAP), it keeps saying invalid mbox files. It worked fine in 0.99.x. It is detecting the right mbox files because it lists the folders and the subscriptions correctly. I am using "default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u" in the config file, but I get the same error with "Detect automatically". It generates nothing in the log files so I am lost!! I tried both outlook and thunderbird but same results. Thanks for the help, Harout S. Hedeshian

[Dovecot] alpha5: (message_body_search_ctx) assert
by Jeff A. Earickson 31 Dec '05

31 Dec '05

Hi, My second case of this assert, gdb analysis of the core dump attached. My setup: Solaris 9, dovecot built with gcc 4.0.2, mbox format, imap usage only. INBOX is NFS mounted from another Solaris 9 system, index files are local. Syslog complaint is: imap(user): file message-body-search.c: line 414 (message_body_search_ctx): assertion failed: (input->v_offset == part->physical_pos + part->header_size.physical_size) Jeff Earickson Colby College

[Dovecot] 1.0alpha5: fcntl() locking problem
by Jeff A. Earickson 31 Dec '05

31 Dec '05

Hi, My setup: Solaris 9, /var/mail is NFS mounted from another Solaris 9 box, home directories and dovecot index stuff is on local ufs filesystems. I upgraded from alpha4 to a5 about 36 hours ago. Dovecot is configured like so during the build: VERSION=1.0.alpha5 CC=gcc CFLAGS="-g -O" CPPFLAGS=-I/opt/openssl/include LDFLAGS=-L/opt/openssl/lib \ ./configure --prefix=/opt/dovecot.$VERSION --with-ssl=openssl \ --with-ssldir=/opt/openssl/ssl > configure.out This afternoon dovecot basically locked up where a lot of people (including me) were getting: imap(user): fcntl() failed with mbox file /var/mail/user: No record locks available for syslog messages, and their mailbox operations would fail. In my case pine just closed the mailbox with an internal error. I did a quick fix by stopping dovecot, killing all dovecot processes, killing /usr/lib/nfs/lockd on the dovecot server, and restarting lockd. Ideas? Suggestions? Jeff Earickson Colby College
