hi All, I have a srange problem. Before dovecot there was a courier imap and it worked just fine. The client(s) are the same then before, so I think, this is an server side problem. I have a user with Outlook and he uses pop3 and leaves messages on server. Sometimes the messages get downloaded again, when he starts the outlook. Not all, but 7-9 hours back. uidl format is like it's

I'm in the process of migrating a large number of maildirs to a 3rd party dovecot server (from a dovecot server). Tests have shown that using imap to sync the accounts doesn't preserve the uidl for pop3 access. My current attempt is to convert the maildir to mbox and add an X-UIDL header in the process. Run a second dovecot that serves the converted mbox. But dovecot's docs say,

Hi ! POP3-RFC (1939) speaks about UIDL command: The unique-id of a message is an arbitrary server-determined string, consisting of one to 70 characters in the range 0x21 to 0x7E, which uniquely identifies a message within a maildrop and which persists across sessions. When I issue an UIDL command (dovecot 0.99.10.9) I get replies like 1 1093990148.1 2 1093990148.2 3 1093990148.3 ... . You see

TESTED AND RUNNING, MIGRATING from MBOX to MAILDIR, PRESERVE UID and OUTLOOK sees the email as downloaded. I hope this helps a lot of people out there. Feel free to post this somewhere else too. By: Horn Wijaya (hwijaya at nodens.biz) 8th May 2008 I have been searching for weeks for a foolproof method to migrate all my users mbox to maildir/dovecot without having the pain of downloading

Hi all, I'm migrating a Postfix + Dovecot 1.0 server with mboxes to Qmail + Dovecot 1.4 with Maildirs and encounter the following the problem. Using perfect-maildir.pl from: http://perfectmaildir.home-dn.net/ i can relatively succesfully convert the mbox to a Maildir. The problem, however is that clients with "leave mail on server" set to on retrieve all email a 2nd time. I

I think dsync wants to sync mailboxes between configured and working servers with users already defined. Yes, of course. And the directory structure was pretty much identical between the two. Which was how I was able to write and run the rsync script. I think at this point, I'm past

Hi I run a small mail server with Dovecot and postfix. Several of the accounts are popped by an external email provide I use, mostly out habit and also for a bit of redundancy. I have no details on that external server except that it uses exim. Lately, it's been repopping mail from accounts (mail is left on the server so I can use IMAP) at fairly frequent, but undetermined, intervals. Before

Hi, I'm using dovecot 1.2.15 on debian squeeze with maildir, and I want to move index files out of the mailboxes disk to reduce disk I/O. I need to get the assurance that the switch is completely transparent to my clients (IMAP and POP). I read the wiki documentation and have found this thread (http://dovecot.org/pipermail/dovecot/2009-September/042665.html), which makes me

Manao ahoana, Hello, Bonjour, We currently run courier POP . We would like to switch to Dovecot. I encounter problems when migrating the UIDL because we have big Maildirs and POP re-downlading the data is not possible for most of the users. I tried the http://www.dovecot.org/tools/courier-dovecot-migrate.pl script but I still have the re-downloading event. What are your stories and advices

This past holiday weekend has resulted in some real groaners when it comes to bugs in our dialplan, making obvious the need for some changes in our procedures. First, our hours of operation for Christmas Eve, Christmas, Boxing Day and New Year's Eve had changed with little to no notice. Okay, fine, whatever, I fix. Our Christmas Eve hours (made worse by being Monday this year) dialplan

Hi, today we have a problem our mail server about user accounts. (something about prefetch) anyway i corrected, but some clients re-download emails again. how can i stop this .I've read about some forums about UIDVALIDITY ? is it posibble prevent clients redownload emails with pop3 ? thanks in advance. -- Sel?uk YAZAR

Hi, Considering the scenario, where you have some old account with a different POP3 UIDL format and you migrate them to dovecot. So these old UIDLs would be saved to dovecot-uidlist. At some later time you want to introduce a virtual POP3 INBOX like described on: http://wiki.dovecot.org/Plugins/Virtual So you decide to make the new UIDL format "%f" - to make them unique across

Heya, We are in the process of migrating from qpopper to dovecot as POP3 server (and IMAP as well) and we hit the UIDL issue with dovecot. Qpopper uses its own algorithm to create UIDL values and if you set it up to write them down in the mbox file as X-UIDL, then dovecot can use them (pop_uidl_reuse = yes). But if you don't use that feature from qpopper, than X-UIDLs are missing and there
