I'm using a combination of Postfix and Cyrus IMAPd.
Granted, probably not what OP was asking for, but privacy wise, this is almost certainly more water tight than any of the other options.

Same, Postfix but still using Dovecot for the IMAP server. Works just fine still though.
Please would you elaborate or point me in the direction of further information? This looks interesting.
Do all or any of these options offer filtering?
Get your own domain and sign up with Opalstack.
mailinabox gives you email, calendar, tasks, and nextcloud apps if you're willing to setup your own VPS and suffer through some setup, about $10-20/month
The closest in features would be Infomaniak.
migadu.com, it's a Swiss company with servers in France (great privacy laws). You can host multiple domains and unlimited mailboxes on the same account, which starts at $20/year. They limit on numbers of emails sent/received (200/20/day on the smallest account) and on total account space (5 GB smallest), not on features. You can host multiple domains, multiple mailboxes, multiple aliases, individual login per mailbox, TLS connections, IMAP/SMTP/POP/webmail and all the features you can think of.
