If you don't mind windows, I can recommend smatermail. It does everything in a single package (smtp, imap, webmail). There is a free tier. There are also additional paid features, I pay for ActiveSync, mostly for the ease to configure a client to set up everything (contacts, calendar, emails). Plus they have a rest api so you can automate certain things.

Thanks. I assume you mean this?

That's way more than I need, and if I can avoid Windows I will, but...it is cool to see a competitor to Exchange.

Yeah but you don’t need to use all the features (I only use emails, contacts and calendar). Most of the defaults are reasonbable, you just need to harden the security a little bit.
