I need to move some mailboxes (for a specific domain) from my mailcow to another Mailserver. The Sync feature of mailcow (via imapsync) just Support an Import from other Mailservers to mailcow - so I need it the other way around … :-( Is there any option to configure the sync in opposite direction? Eg via the Parameters? Thanks!

No since the server to which is should be synced is hardcoded to localhost https://github.com/mailcow/mailcow-dockerized/blob/master/data/Dockerfiles/dovecot/imapsync_runner.pl#L148 But you can either install imapsync on your other server, run imapsync with the right parameters from the dovecot container or use the GUI version from the maintainer of imapsync https://imapsync.lamiral.info/X/

@"esackbauer"#p15994 cool , were ? (not found on the GUI ) still on Host field [upl-image-preview url=https://community.mailcow.email/assets/files/2024-05-24/1716552609-717025-2024-05-24-14-09-15.jpg]

ImapSync to migrate from Mailcow to other provider

KarstenDE

So is there an option to switch the direction or the server1/server2 assignment?
Benefit of the existing solution is that I do not need the passwords of the existing mailcow mailboxes.

Is it possible to change the used commandline?

Thanks!

Im also intrested 🙂 Any Hints ?

I don’t know how it was in 2021 when this thread started, but now you can freely configure which server ist host1 and host2

cool , were ? (not found on the GUI )

still on Host field

I am sorry, I mixed that up, you are right, you cannot switch both hosts.

Anyways, it syncs both hosts, and therefore it syncs in both directions by default.
So there is no need to switch the 2 hosts.
Thats why its called imapsync, and not imapcopy 😉

thats wrong 🙁
https://docs.mailcow.email/de/post_installation/firststeps-sync_jobs_migration/

“Sync jobs are used to copy or move existing emails from an external IMAP server or within mailcow’s existing mailboxes.” >>> one way 🙁

i tried them out ,, no two way sync :/

Ah yes, you are using the other direction. Imapsync can’t properly 2-way sync:
https://imapsync.lamiral.info/#CANTDO

Imapsync is not suitable for maintaining a synchronization between two active imap accounts while the user is working on both sides. See why in the Two Ways Sync document. Use offlineimap (written by John Goerzen) or mbsync (written by Michael R. Elkins) for bidirectional (2 ways) synchronizations.

As you cannot easily modify the sync jobs the other way around in mailcow, it seems you need to do this outside of mailcow.
Try this:
https://hub.docker.com/r/gilleslamiral/imapsync/

this may work but as “KarstenDE” wrote

"Benefit of the existing solution is that I do not need the passwords of the existing mailcow mailboxes.
Is it possible to change the used commandline?"
.. i.e. via cron job

esackbauer

You could play around with this:
mailcow/mailcow-dockerizedblob/36b5cccd186090d726de62b6b00d1e842e67aacd/data/Dockerfiles/dovecot/imapsync_runner.pl#L148
And reverse the host1/host2 incl. options.

will work but evry update this will be reverted or ?
on the other and only that way will work , sync in dosent work anymore

esackbauer

worryboy
Of course it would not survive an update.
Another solution is to use an imapsync container outside of mailcow. You lose the integration, but you get all the flexibility.

worryboy

esackbauer

sure , but as KarstenDE wrote the integration is the Plus of mailcow. “Benefit of the existing solution is that I do not need the passwords of the existing mailcow mailboxes.”

how can i request a feature ?
