I use postfix, dovecot and snappymail. Very happy.
I already had a well-configured postfix (DKIM, DMARC) for web applications, so adding dovecot was easy. It's also really powerful, you can define who gets mailboxes in scripts. I tried going with providers but I couldn't get this kind of power.
Self hosting with mailcow.
Alternatively proton.me
Mail in a box or poste.io
3rd for MIAB. I use Linode. I believe most ISP's restrict access to mail ports so running at home is probably not possible.
