Don't know if UX is as big of a problem as you think. My understanding is that the problem with self hosting is reliability and spam prevention. For reliability, self hosting a server that will always be available is hard. Not getting an important email because your server went offline is a massive bummer. Similarly, while filtering spam on your end might be doable, self hosted email servers are often filtered by major email providers for looking like spam.
