I have a backup of one of my email accounts in the Maildir format. I made it manually, and it’s not from a Mailcow instance.

How to import such a backup into a Mailcow? Will I also have to create a domains and mailboxes that exist in a backup in Mailcow first?

I’m aware of the 2 import/export bash scripts of Mailcow, however, can they be used in this case?
