comment Would it make sense to use Bcrypt and PBKDF2 together?
Protect from a broken hash: if all are working ok, brute-force would spend x times in the first hash and y time in the second hash, with a total of x+y. If any is fully compromised, the attacker will spend the total of 1+y or x+1, and the order didn't matter.

comment What is the most reliable way to transfer emails without specific recipient support?
Don't want to prevent discussion, ideas, etc., but in other words you're asking "We know email wasn't built to be that secure, but it's still used. We know there's a lot of research about it, but all solutions need some change in the current model. Is there a magic solution to solve all those weakness in it's design without any change?"
