[Dovecot] Need fast Maildir to mdbox conversion
by Jeff Gustafson 29 Mar '12

29 Mar '12

I looked around the 'Net to see if there might be a custom program for offline Maildir to mdbox conversion. So far I haven't turned up anything. The problem for us is that the dsync program simply takes a lot of time to convert mailboxes. I wonder if time could be saved with a program that is optimized to convert mailboxes without the fancy locking that dsync needs to do. Does have (or seen) a tool that could do this? We're hoping that converting away from Maildir will help us speed up the backup processes by reducing the number of files to process. ...Jeff

[Dovecot] Using getmail with sieve
by Orr, Steve 28 Mar '12

28 Mar '12

I'm trying to setup a personal "mailmover" where I use getmail to retrieve remote IMAP server mail and load it into my local Dovecot then filter all email on the Dovecot server side with sieve. (I'm using Dovecot v. 2.0.9 with IMAP/Maildir.) 1) From the docs I gather that Dovecot sieve will not work as mail is loaded by getmail and I need to refilter the email after it has been loaded with getmail, right? 2) In http://wiki2.dovecot.org/HowTo/RefilterMail it says, "This HOWTO helps you create a folder for mail that needs refiltering..." But contrary to the doc I don't see any actual instructions about creating said folder. The HOWTO assumes mail already exists in a folder called "REFILTER' but doesn't say how this folder was populated. "How to?" 3) As a test I manually created the "REFILTER" folder and put my inbox mail in it (with Thunderbird) then following the HOWTO I ran my getmail script and my sieve script performed as expected. 4) How do I automate this? I tried a new getmail script to run against the inbox and tag new email so a subsequent getmail script could move it into the REFILTER folder for later sieve processing. This seems like way too much work. The HOWTO doc seems incomplete or presumes other knowledge, especially for an IMAP server and email sieve nubie. TIA, D.

[Dovecot] Dovecot upgrade from 1.2.x to 2.0.x: roundcube/squirrelmail sent folder doesn't work any more
by Gerhard Wiesinger 27 Mar '12

27 Mar '12

Hello, After upgrading from 1.2.x to 2.0.x I'm having problems using sent folder in Webmail applications like roundcube mail and squirrelmail. Relevant config dovecot.conf: mail_location = mbox:~:INBOX=/var/mail/%u Different LIST behaviour from rawlog: 1.2.x: with Prefix ~/Mail A002 LIST "" "~/Mail/sent" * LIST (\NoInferiors \UnMarked) "/" "~/Mail/sent" A002 OK List completed. 2.0.x: with Prefix ~/Mail A0003 LIST "" ~/Mail/sent A0003 OK List completed.: Configured prefix for private spaces in roundcube mail is ~/Mail . Roundcube Webmail application checks for existence of the folder but dovecot doesn't return anything in 2.x.latest. Is this by design? Any ideas to fix it by configuration? (I tried prefix Mail/ in roundcube mail without success) Thunderbird works well. Thnx. Ciao, Gerhard

[Dovecot] Problem with DOVECOT - long authentication time

[Dovecot] Dovecot IMAP is broken after upgrade from 2.1.2 to 2.1.3
by Michael Neubert 27 Mar '12

27 Mar '12

Hello, I just upgraded my servers from Dovecot 2.1.2 to Dovecot 2.1.3-0~auto+5 by using Debian binaries from "http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.1 main". The config was not touched but now IMAP connections are not possible anymore (LMTP works fine). When I try to connect to a mailbox, the connect fails.

[Dovecot] dovecot-1.2.9: OK No messages copied
by Attila Sipos 26 Mar '12

26 Mar '12

Hi, When I issue an IMAP copy command using the wrong UID, the server gives an "OK No messages copied" response. This seems like the wrong response to me. If the UID doesn't exist, then it should respond with a "No" response - maybe something like "NO - copy error: bad UID" I believe "OK No messages copied" would only be a suitable response if the email with the supplied UID had already been known to be copied successfully. I am using dovecot 1.2.9 - has this been fixed in newer versions of dovecot? Regards Attila Attila Sipos Netcall Telecom Ltd Registered in England 2831215.

[Dovecot] Many messages clustered around the same date.saved value
by Joseph Tam 26 Mar '12

26 Mar '12

Subject: Different user messages clustered around the same date.saved value After updating dovecot to 2.1.3, I can now use "doveadm expunge -A ..." to iterate through all user trash folders and expunge old messages. However, I noticed a strange thing: querying what would have been deleted doveadm -ftab fetch -A "date.saved" mailbox Trash savedbefore 7d showed many date.saved values are clustered around the same timestamp, even among different user's Trash mailbox. One user's trash mailbox having the same date.saved is explained by a user deleting a lot of message at one time, but I can't explain why many different users would have messages with the same (or closeby) date.saved value. For example, the output of the above query on my system showed the 10s window /2012-03-05 18:08:0[0-9]/ matched 7658 messages among 22 different user Trash mailboxes, which is statistically unlikely. I did't see anything special in the dovecot logs at this time to explain this. What would cause this? Joseph Tam <jtam.home(a)gmail.com>
