While it isn't hosting your own mail, Nextcloud does have some nice webmail interfaces, like rainloop, that can be configured using any imap/smtp server, like a desktop mail application.

My hosting provider has hosted my email for 15+ years (with my own domain), but their webmail isn't super great, especially for my non-techy family. They mostly use the mail app on their iphone, but Rainloop through nextcloud made it really easy for them to check through the web.
