Mail migration using dovecot master user impersonation

[djxx]

I'm trying to migrate mail from another server to Cloudron using imapsync. I want to use dovecot user impersonation so I don't need to worry about user passwords, and I can just use an admin account.

Does Cloudron allow this? For example, connecting as: user*admin with the admin's password to impersonate the user?

If so, what is the user and password I should use for it?

@djxx When you create the mailbox in Cloudron, you can set multiple owners via Groups functionality. Set the mailbox owner to a group and you can use any of the member's password. After importing, you can remove the group and set it back to the intended user.

@joseph Thanks for this! I was trying to wrap it up last night so I decided to just reset all the users passwords to a known password, and then send them a password reset link to change it to their old password on their own. I will definitely keep the group approach in mind next time I'm migrating to Cloudron - but my next server likely won't migrate until XMPP gets some love ( https://forum.cloudron.io/topic/10465/xmpp-server-prosody/26?_=1723504540984 )
