We are running our own mailcow instance (new system) and need to mass import existing mailboxes from an exchange server using IMAP. UserIDs on exchange differ from new system. The target is to run a (bash or whatever) job to bulk mirror existing mailboxes. Users are already registered with new UserIDs in mailcow. Example for illustration purposes: - userID exchange `smith@our_exchange.com` - mailbox has several (sub)folders that need to be imported too - new userID in mailcow: `john.smith@our_mailcow.com` I'm aware of the dovecot `dsync` command but unsure whether this would work with mailcow as well. Any other solution highly appreciated too Txs in advance -mgw

Mass import existing mailboxes from an exchange server w/ IMAP

mgw2013 your users can do that by themselves, or you can create the sync jobs for them, both directly via the mailcow UI: https://docs.mailcow.email/post_installation/firststeps-sync_jobs_migration/?h=sync

So no need of using the dsync command

If you’ve got a LOT of mailboxes you can use the API to create the sync jobs:

DocFraggle Sure. The issue at hand is: existing user are used to pure RDP operations and we want to avoid any distraction at his point in time (because there will be umpteen distractions coming down the road…).

I’m aware of the sync job thing but haven’t spotted a way to “mass enter” those jobs for 100+ users… ideal would by a .csv with old and new name of mailboxes to be imported whereever (my thought was a bash job) plus auto execute for all users thereafter (means passwords to be supplied as well if I’m not mistaken).
