Migrate domain from one MIAB to a new MIAB?

#1

Is there a method to migrate a single (or several) domains from one MIAB to another new MIAB?

#2

Not automatic that I am aware of.

To do so manually, you would need to create the users/aliases on the new installation and then either copy the mail directories or use a tool such as imapsync.

#3

Is there a method to manual stop receiving mail for just one domain or user?
