Huh. I've been seeing a lot of startup friends transition into public policy & lobbying centered around tech. I wonder if legislation is the next phase of the industry?
"half-defeating the purpose of having privacy by running my own server."
Is there even privacy in e-mail? Say I have a server that talks TLS. There's still no guarantee the other end wants to, and even if it does it's just going to store my mail on disk unencrypted anyway. Even if it's encrypted there, it has to be decrypted and read by a process to make a webpage out of it, or, to allow a client to download it, where it will probably rest unencrypted on their system. You're not getting privacy.
If you want privacy, encrypt it (pgp), or, use another protocol that is encrypted end-to-end and stays encrypted even after the recipient reads it.
