I should have said for a product like Lavabit, ie mail as secure/private as SMTP likely gets right now, I hope it wouldn't be unreasonable. However, in my heart of hearts, I knew it was too much to ask for.

I guess anyone that knows how to create and setup a client side TLS cert and key would also already know privacy and SMTP can't really live together, and would setup a deaddrop for gpg encrypted messages.
