I self host most of my digital life but I will never host my own email or PW manager for the simple reason that if I screw up either than I could lock myself out of my ENTIRE digital life.

Also, since email is only as private/secure as the weakest user in the conversation, it seems to me like I would get a very minimal privacy gain from doing so, not worth the risk for normal everyday usage IMHO.

If I really need to communicate securely with someone there’s better options out there than email anyways.
