Can't recommend mailcow[1] enough! Took me a couple of hours setting up and moving 6 domains and 31 mailboxes after having to leave a shady provider quickly.
It includes everything like automatic certs, SPF, DKIM and has imapsync with a simple admin interface built in. Also comes with SOGo for webmail.
