[Dovecot] Outlook client timeouts on sending mail
by J Moore 20 Mar '07

20 Mar '07

This may be a sendmail question, but I thought I'd ask here first: I set up an Outlook client to use secure IMAP and secure SMTP. When sending a message, the client typically times out once or twice and presents an error message indicating the server isn't configured for secure delivery. With a little persistence, Outlook eventually makes a successful connection, and the message goes on its way (2-3 tries). Any pointers as to where to look for the problem? Thanks, Jay

[Dovecot] Best way to migrate from Qpopper to Dovecot
by Torsten 20 Mar '07

20 Mar '07

Hi List, what do you think is the best way to migrate (to a new maschine) round about 30000 mboxes (Qpopper) with an amount of 43Gigs data, to maildir format (Dovecot). I think there are two ways: 1. - stop services (smtp and pop3) on the old maschine - copy the mboxes to the new maschine - run a conversion script (for excample: "Perfect_maildir" http://perfectmaildir.home-dn.net/) - start the services on the new maschine (smtp and Dovecot) 2. - tell the users to use the new server (from the day X) with the new feature (imap) - stop the smtp on the old maschine on day X - leave the old maschine active for a month or so (let users get their "old" mail) With the first alternative we have a high downtime, because of copying the mboxes and converting the stuff. What do you think? Thanks Torsten

[Dovecot] Courier's courierpop3dsizelist - uid convert
by Marcin Gryszkalis 19 Mar '07

19 Mar '07

Hi Migration page [1] on wiki says "Courier version 3 (younger versions) Here everything has changed: Courier's UID data are now stored in courierpop3dsizelistand in a completely new format. But it's still possible to convert it to the format dovecot needs (link to perlscript and further configuration details will follow later). " but there's nothing more. I couldn't find any ready to use script for the conversion. Maybe somebody has it ready or could help me, I can write perl oneliner but I don't understand the format of index files. dovecot's is like this 1 1174291188 518 1 1174181234.P58178Q0M660793.sas.xxx.xxx.xx:2, 2 1174286738.P16096Q0M408737.sas.xxx.xxx.xx:2, courierpop3dsizelistand is like this /2 703 1105349624 1135668673.V41dI2c3c85.sas.xxx.xxx.xx:2,S 12176 184:1105349624 1135766433.V41dI2c3c95.sas.xxx.xxx.xx:2,S 170450 185:1105349624 I understand every line starts with mail filename, but I don't understand latter values. I'm also not sure about first line of dovecot's file. Any help would be appreciated :) greetings marcin [1] http://wiki.dovecot.org/Migration -- Marcin Gryszkalis, PGP 0x9F183FA3 jabber jid:mg@fork.pl, gg:2532994 http://the.fork.pl

[Dovecot] Dovecot 'suicide'
by Luigi Rosa 19 Mar '07

19 Mar '07

I have a Dovecot installation on a Fedora 4. With the last update from Dovecot RC10 to Dovecot RC27, the daemon kills itself every night with this error: Mar 17 05:23:11 mail dovecot: Time just moved backwards by 6 seconds. This might cause a lot of problems, so I'll just kill m yself now. The error appears just after the night maintenance script executes a ntpdate syncronization ntpdate is version 4.2.0a(a)1.1196-r Well, 6 seconds are little more than a blink in human perspective, even if it is a long time for a computer point of view. Couldn't be possible to add a configuration option to avoid the suicide? Any other option other than suicide is better, because there could be situations of really unattended servers.

[Dovecot] Changed CONTROL= path causes POP3 to fail, whereas IMAP is working (rc25 & rc26)
by Steffen Kaiser 19 Mar '07

19 Mar '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I'm testing some configurations, in the process I used a wrong user setting causing POP3 (get new messages) to fail, whereas IMAP was still working. An easy fix was to remove the entire /var/cache/dovecot/1012/ directory, both index and index/control were re-created and do work. So my guess is that the existance of the indexes causes some trouble when just the control information is missing. Here is what I had done: The mailbox of "dvtest" was fully working with the correct setting from the config file: mail=maildir:/home/dvtest/MailDir:INDEX=/var/cache/dovecot/1012/index:CONTROL=/var/cache/dovecot/1012/control (no "/index" in the CONTROL= part). Then I created a LDAP entry for the user dvtest wrongly: mail=maildir:/home/dvtestMAIL/MailDir:INDEX=/var/cache/dovecot/1012/index:CONTROL=/var/cache/dovecot/1012/index/control The CONTROL= ended in "/index/control" rather than just "/control". (Note: I also mv'ed /home/dvtest to /home/dvtestMAIL in order to see, whether the LDAP attribute is getting used.) Afterwards IMAP is working, but POP3 returns "Couldn't init INBOX: Unknown error"; Thunderbird displays the error: "The STAT command did not succeed. Error getting message number and sizes. Mail server ux-2s11-9 responded: Couldn't sync mailbox." When I correct the LDAP attribute, hence the CONTROL= path ends in "1012/control" again. The mailbox is working with POP3 again. The INBOX of the erroreous control path does not contain any dovecot-* files? The message I deleted and expunged (see logs) were from the INBOX. /var/cache/dovecot/1012/index/control# lr .: total 16 drwx------ 4 dvtest Debian-exim 4096 2007-03-07 09:36 ./ drwx------ 12 dvtest dvtest 4096 2007-03-07 09:34 ../ drwx------ 2 dvtest Debian-exim 4096 2007-03-07 09:36 .Addresses/ drwx------ 2 dvtest Debian-exim 4096 2007-03-07 09:35 .INBOX/ ./.Addresses: total 24 drwx------ 2 dvtest Debian-exim 4096 2007-03-07 09:36 ./ drwx------ 4 dvtest Debian-exim 4096 2007-03-07 09:36 ../ - -rw------- 1 dvtest Debian-exim 12756 2007-03-07 09:36 dovecot-uidlist ./.INBOX: total 8 drwx------ 2 dvtest Debian-exim 4096 2007-03-07 09:35 ./ drwx------ 4 dvtest Debian-exim 4096 2007-03-07 09:36 ../ The attached file contains the full log of a session POP3 (get new messages), IMAP, expunge in INBOX, POP3 again.

19 Mar '07

Hello IMAP users here have a *lot* of folders living in their mailhub home directory Converting the INBOX doesn't seems to be a problem I've found scripts that do the job :-) But How to convert IMAP folders from UW format ( one file / folder ) to dovecot format which seems much more sophisticated. Does anyone has written such ( nice) utility ? Thanks a lot Frank

[Dovecot] Dovecot - with LDAP auth backend

Escape character is '^]'. * OK Mail ready a1 login ldapuser password a1 OK Logged in. a2 getquota "" * QUOTA "" (STORAGE 0 10240) a2 OK Getquota completed. if I were to change (D) to quota = maildir And added in an attribute called "mailquota" in the entry uid=ldapuser,dc=mydomain,dc=com, give it a value 10240000 (is this correct? should it by in bytes or in kilobytes?), then reinitialize the mailbox by deleting the ~/Maildir directory (or in this case /home/ldapuser/Maildir) Did the telnet localhost 143, this is what I get instead Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. * OK Mail ready a1 login ldapuser password a1 OK Logged in. a2 getquota "" * QUOTA "" () a2 OK Getquota completed. Even after I've added the attribute mailquota in the ldap for the entry uid=ldapuser it still does not look like its taking any effect at all. Regards and thanks in advance.

[Dovecot] using sieve plugin
by Kendall Shaw 19 Mar '07

19 Mar '07

Hi, I have installed dovecot on ubuntu edgy linux by retrieving the source debian package, building and installing the package and then building and installing the sieve plugin. However, I get no log messages indicating errors and as far as I can tell, my .dovecot.sieve script is not being used. I have introduced a syntax error in the script and see no error message. In dovecot.conf I have: log_path = /var/log/dovecot.log invo_log_path = /var/log/dovecot.log protocol lda { module_dir = /usr/lib/dovecot/modules/lda mail_plugins = cmusieve log_path = /var/log/dovecot-deliver.log info_log_path = /var/log/dovecot-deliver.log } I am using exim with dovecot. I've tried using a .forward file (I'm the one user on the computer). Alternately, I've tried creating the dovecot_deliver "transport" in exim and changing the localuser router to use it. Still, I get no messages from deliver and no error messages from dovecot or exim. The file dovecot-deliver.log is not created. Do you have any suggestions that can help me get it working or to see why it is not working? Kendall
