Solved Move email user to another domain
Is there a way to move an email user from one domain to another? We need to migrate a user from domain1.xyz to domain2.xyz. The new feature to define aliases with any configured domain works great, but when sending a mail as an alias it is send "on behalf of" and we would like to switch the user mailbox completely to a new domain. Any way to do this without creating a new account and migrating all mails?
If you are using thunderbird or outlook, add the new account to it, then literally drag and drop email from old -> new, give it a few hours to sync (depending on how big the mailbox is, it can take a few minutes to a couple hours).
Or you can also user the https://imapsync.lamiral.info/ tool.
You should be able to follow the instructions at https://cloudron.io/documentation/email/#import-email to migrate mails between mailboxes on different domains.
Thank you! A local installation of imapsync on the server did a great and fast job in transfering the emails from one account to the other.
