I wrote some free software which does *some* of what you described,
early last year. You can read about it and download it from my blog:

https://grepular.com/Automatically_Encrypting_all_Incoming_Email

It encrypts all incoming email on the server, but I handle decrypting
inside my clients rather than using a proxy. It's pretty simple, and
will work with any MTA which can filter an email through an external
command. I use it with Exim. Other people use it with Procmail.
