similar to: Converting mailboxes from one Maildir format to another

Hello all, I'm facing the need to migrate from a proprietary IMAP server to Dovecot. The migration must be as smooth and transparent as possible. The mailbox format I would want to use is Maildir++. The storage format used by the current server is unknown, and I don't look forward to trying to reverse-engineer it. This leaves me with the option of reading the mailboxes using IMAP.

I run a pair of dovecot servers for personal small domains with several layers of backup in place ... - The two dovecot servers replicate to each via a Tinc vpn mesh. That gives email resiliency. - All mail is replicated via offlineimap to a 3rd server over that Tinc vpn. It's on the mesh, it has space, so why not ? - All mail is replicated as well as via mbsync to a zfs dataset on my

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, 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,

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 Robert, [... snip ...] of course I'm totally with you: asking other people for help, is often a good - if even not the only way to getting things done. It was not my intention to insult you! I hope this did not come in to your mind ... Personally I would have a look at the mentioned Dovecot-backup-script as a start. It does really a very good job! Cudos to Klaus Tachtler!

Hi, What are people doing for backups ? My current process is LVM snapshot and backup from that to NFS share. But there seems to be hints around the internet that people use/abuse "doveadm backup" for backup purposes even though it seems its original intention was for transferring mailboxes between dovecot instances. Assuming its ok to "doveadm backup" to an NFS share, is it

Hi, I'm using dovecot to serve up a Maildir created/served by offlineimap. The layout is typical (as far as I know) of maildirs, with the root folder having cur, tmp, new, and subfolders being a folder within the root folder. Since I'd previously used Evolution to access this maildir, my subfolders were actual subfolders (separator /). Anyway, it all works spiffingly well, except that I

Hi, I am looking for tools to migrate Mails from one IMAP-Server to another. Until now I have always used imapsync, but it seems very slow. Even over a 2x10GB/s connection I only get speeds of about 600KiB/s, because the programm always pauses betweeen every single mail. Does anyone here have a suggestion for an alternative? Thanks in advance Julian

Hi, I replaced HDDs in my home server and reinstalled the OS (Ubuntu 17.04). Since I had some time I reviewed my Dovecot configuration and changed a couple of things, including mailbox format. Now I would like to migrate e-mail (about 20G -- I use this server as an e-mail archive). The Maildir is available on the (old) hard disk. The new dovecot is running. What should I use? Would mbsync work?

Hello, I've got a Postfix/Dovecot server setup. Currently Dovecot is version 2.3.6, and it's using Maildir storage. The mailbox is: mail_home = /home/vmail/mailboxes/%d/%n mail_location = maildir:~/mail:LAYOUT=fs I'm wanting to convert from Maildir to sdbox. I looked at: https://wiki2.dovecot.org/MailboxFormat I was initially thinking mdbox but that's multiple messages per

I am trying to determine the best way to link different private networks together, similar to the branch office example given online. However, in my case, the private networks are split up. For example, I would like to connect subnets such as: 10.30.0.0/16 172.23.0.0/16 10.90.50.0/24 192.168.3.0/24 How does this affect my tinc-up files? What subnet mask do I give the tinc interface? Can this

I'm a total newbie regarding imap servers. I'm trying to set up a Offlineimap/dovecot/Gnus system and Gnus complains that it cannot access the maildir... Here is my setup, put together by copying stuff from around the web without any prior knowledge of these tools... * Offlineimap is setup to use the $HOME/Maildir-free/, using --8<---------------cut

Hi I have use dovecot together with offlineimap to download my gmail account on a single user computer and I have only one maildir (~/Maildir). As I switched to Mac, I would like to use spotlight to index my mails, which apparently does not work as they are in hidden directories (.directories). So I would like to change to LAYOUT=fs. Is there an easy way to migrate my email structure? I have

I use offlineimap to sync my remote IMAP-server with my local IMAP-server (maildir format). But I don't understand this behavior: every new mail in the INBOX has a file-date which is one hour in the future. Is this 'normal'? Is this a problem of offlineimap? I tried this debugging (for dovecot): mail_executable = /usr/lib/dovecot/rawlog /usr/lib/dovecot/imap and this (for offlineimap):

Hi, I think you tried to read cyrus mails folders directly. I was talking about fething mails from cyrus over imapc connection.

Silly question? Which is preferred? MailDir or Mbox? (directory vs flat file) How would you do this when migrating from an old server to a new one?
