William,
While not trying to discourage you from your efforts, I would like to
recommend that you not reinvent the wheel. The list you have presented
already has some possible solutions to it which I have listed below.
Delayed transmission: Are we talking about rate limiting, or delivery of
specific messages at specific times? Either way this is more an MTA issue
in my eyes, than a protocol issue. Rate limiting is already availible in
at least one major Unix MTA.
Delivery notification: Possibly a protocol issue. This is availible as a
semi-standard. RFC1891 is your friend:

Secure communication: TLS, SSL.
