Hi Friends, I would like to ask you a suggestion: I need to migrate a imap server to a new one and then dismiss the old one. Reading from relative Dovecot documentation page (https://wiki.dovecot.org/Migration), more tools are shown: UW-IMAP's mailutil, imapsync, YippieMove and Larch. The each mail servers are Linux based, one of this (mine) is Dovecot. Based on your experience which of

Imapsync for sure. Have used it for both IMAP to IMAP and IMAP to Exchange migrations. Works great. > On Dec 3, 2017, at 2:08 PM, x9p <dovecot at x9p.org> wrote: > > Hi, > > I vouch for imapsync.

It is dreadfully slow -- I used it to export some of my users' mailboxes to Gmail or other remote mail servers, and I could almost cut&paste the messages faster. Like Aki

I think Davide was asking about dsync. If so, the answer is no: dsync works only when both servers are Dovecot and needs some additional configuration to work

Thank you for the reply. I did find imapsync whilst perusing Google. I will give it a shot, it sounds more realistic/reliable. I have a hoard of emails going back to 1999, so I want as few errors as possible :) On 11/7/15 3:31 PM, Philon wrote: > Hi there, > > I was in the same position, but for mutliple accounts. Still you might want to look at imapsync

Hello, Because it did not work ? In a similar situation, we where forced to use isync/mbsync in imap to imap mode because dsync did not work. It was reported here more than a year ago (May 2014). Time to time, I see the same report from other trying to use dsync to do a migration to dovecot. Dsync is a very appealing and elegant solution to this usage, but it does not always work in real

Hi, I'm using Imapsync to sync messages from an Exchange 2003 server to a Dovecot 1.1.11 server. The problem is that users' mailboxes are huge, several gigabytes with tens of thousands of messages. First Imapsync connects to Exchange and then to Dovecot, and then starts to get Inbox info from Exchange. By the time it gets this info, the connection to Dovecot has timed out. I realize the

Dear dovecot list, I'm using Maildir as mailbox format. Is there any recommendation for the namespace hierarchy separator? Currently I didn't set any. So it is the default of dot '.' I'm switiching from a rather unknown IMAP Server called DBMail (http://www.dbmail.org/) Planning to synchronize the mailboxes via imapsync (https://github.com/imapsync/imapsync) Is there

Could you help me trouble shoot this? I am a bit of a rookie and probably screwed something up. I am trying to "make" imapsync, but there is a complaint regarding some Perl problem that I cannot figure out.

Hi, No, I tried fetching over imapc too exactly as you suggested. In my case it was not from cyrus, but from CriticalPath. isync was finally able to do the job, preserving flags and doing UIDs mapping. The most boring part was generating proper config file for thousands of accounts. A working imapc/dsync would have been better. Emmanuel. Le 26/11/2015 15:24, Sami Ketola a ?crit : > Hi,
