since some years i have iredmail up and running, but mailcow looks more elegant to me. There was a discussion some time ago [https://community.mailcow.email/d/706-moving-from-iredmail-to-mailcow-ubuntu] with the recommendation to move the messages with imap sync to the new server.
This implies that both servers run and that the new server has another (sub)domain name. I want to keep the old name in use, so I would have to ‘rename’ the mailcow server after the migration. Can this be done ? This sounds like a way to madness ;-)
Any ideas welcomne and thanks for reading and considering !
