[Dovecot] Corrupted mdbox on LMTP director delivery while user is logged in via IMAP

Hi, we get errors about corrupted indexes and we are losing flags with mdbox on NFSv4: Error: Recent flags state corrupted for mailbox Error: Corrupted dbox file Error: Corrupted transaction log file It looks like a LMTP director problem. The user has IMAP IDLE connections open and lmtp delivers to another host. This leads to nfs corruption problems.

[Dovecot] ntlm_auth in Dovecot
by Leonardo 09 Jun '12

09 Jun '12

Hi, I'm trying getting NTLM auth working against AD in my Dovecot 2.0.15. I'm getting the following error: Jun 08 14:18:11 auth: Info: winbind(?,10.44.3.151): user not authenticated: NT_STATUS_UNSUCCESSFUL "wbinfo -u" reports all the users of the domain and "ntlm_auth --username=%name% --domain="%domain%" gets authenticated successfully. Debugging winbind I can see the following error: [2012/06/08 14:18:11.129611, 10] winbindd/winbindd.c:651(process_request) process_request: unknown request fn number 14 [2012/06/08 14:18:11.129671, 10] winbindd/winbindd.c:738(winbind_client_response_written) winbind_client_response_written[2822:unknown request]: delivered response to client My dovecot.conf is the following: auth_mechanisms = plain ntlm login auth_username_format = %n auth_verbose = yes auth_winbind_helper_path = /usr/bin/ntlm_auth auth_use_winbind = yes auth_debug = yes disable_plaintext_auth = no info_log_path = /var/log/dovecot-info.log log_path = /var/log/dovecot.log mail_location = maildir:/var/mail/domains/%d/%n plugin { autocreate = Trash autocreate2 = Spam autocreate3 = Sent autosubscribe = Trash autosubscribe2 = Spam autosubscribe3 = Sent } protocols = imap ssl = no userdb { driver = static args = uid=100 gid=101 home=/var/mail/domains/%d/%n first_valid_uid=100 } passdb ldap { driver = ldap args = /etc/dovecot/dovecot-ldap.conf } protocol imap { mail_plugins = autocreate } Sounds like there is an issue when Dovecot runs "ntlm_auth". It doesn't appear to be a permission issue (perms are 755). Any help is appreciated. Thank you in advance. -- leonardo.

[Dovecot] [ Re: best practises for mail systems]
by Michescu Andrei 09 Jun '12

Hello, If disk space and bandwidth are affordable (and from your setup it seems that they are affordable as you have everything locally) I would split the mail storage completely and use replication in between n-master servers (n=2 for your case). The replication is not yet fully tested, but Timo is actively working on this feature. The fear of lossing the imap session does not make sense (at least to me) as the client will reconnect automatically in the background. Like this you have no SPOF and no split-brain and you get the flexibility (if needed) to geographically distribute your servers in the the future. Keep each server with its own ip, connect to them via DNS (round robin etc etc). We are currently experimenting with a setup similar to this one, but with geographically distributed servers (trans-continental) (bandwidth limited and high cost).

[Dovecot] Maildir filename has wrong S value

Hello folks, This morning I tried to open an old archive mail folder using Mutt. However, while fetching headers it aborted. Checking the dovecot log gave me this: @400000004fb21996267d37d4 imap(benv): Error: Cached message size smaller than expected (9115 < 9420) @400000004fb21996267e8bac imap(benv): Error: Maildir filename has wrong S value, renamed the file from /home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/cur/1260395566.28175.black,S=9115:2,S to /home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/cur/1260395566.28175.black,S=9420:2,S @400000004fb21996267e937c imap(benv): Error: Corrupted index cache file /home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/dovecot.index.cache: Broken physical size for mail UID 294 @400000004fb21996267eaaec imap(benv): Error: read(/home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/cur/1… failed: Input/output error (uid=294) @400000004fb219962680683c imap(benv): Info: Disconnected: Internal error occurred. Refer to server log for more information. [2012-05-15 10:53:32] in=6503 out=192718 I've retried opening this folder several times, but each time Dovecot only fixes 1 file and then aborts. (the folder apparently has a lot more files with incorrect sizes). My question here is: Why does dovecot abort? Isn't the issue fixed after the rename? Also: The files are not corrupted or unreadable, reading them through the commandline works fine. I've looked through my backups and saw that at least half a year ago this mismatch in size was already present. I've been running dovecot for quite a while, so the cause of this size mismatch might very well be a issue in an older version of dovecot / my configuration. Right now I'm running dovecot 2.1.6, but I've been running the v1.2 version for quite a while before that. Is this something that can be improved in dovecot so it doesn't abort after 1 rename? (of course I could script a rename operation, but that seems like a workaround to me) Thanks for reading. Wouter.

[Dovecot] 2.1.7 altmove not working
by Alex Crow 08 Jun '12

08 Jun '12

Hi list, I've just set up a 2.1.7 server, and have migrated a couple of accounts across from a 2.0.15 server, keeping the old configs. I have a strange problem on the new box in that altmove just doesn't work. I have my main storage under /home/email, indexes under /home/indexes and ALT under /home/email_archive. When I run the altmove command, the following broken symlink is created in /home/email/integrafin.co.uk/acrow: lrwxrwxrwx. 1 email email 54 Jun 8 10:46 dbox-alt-root -> /home/email_archive/integrafin.co.uk/a/acrow/mailboxes But nothing is created in the archive other than the empty directory: /home/email_archive/integrafin.co.uk/a/acrow. My mail_location is: mail_location = mdbox:/home/email/%d/%n:INDEX=/home/indexes/%d/%1n/%n:ALT=/home/email_archive/%d/%1n/%n This worked perfectly on the older server. I have attached my doveconf -a output. Any help much appreciated. Regards Alex

Maybe someone is brute forcing your server's Postfix authenticated SMTP service since Postfix can be configured to use Dovecot's SASL authentication framework. Joseph Tam <jtam.home(a)gmail.com>

Hello! I want to upgrade the docevot-installation from v 1.0.5 to 2.1..7 Now I get the following executing doveconf -n -c /etc/dovecot/dovecot.conf > /home/mail1/dovecot-2.conf doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:217: add auth_ prefix to all settings inside auth {} and remove the auth {} section completely doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:219: passdb passwd-file {} has been replaced by passdb { driver=passwd-file } doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:222: userdb passwd-file {} has been replaced by userdb { driver=passwd-file } The section at line 217 looks like this: auth default { mechanisms = plain passdb passwd-file { args = /etc/dovecot/passwd } userdb passwd-file { args = /etc/dovecot/passwd } How do I change it to fullfill the new needs? And how do I handle line 217? add auth_ prefix to all settings inside auth {} and remove the auth {} section completely ? Thanks for help! Andreas
