You cannot force any other party to apply YOUR policy to THEIR systems. "Your server your rules, but my server my rules" :-) Furthermore mandatory tls can fail for a bunch of other reasons except from "not offering tls at all" ex no common cipher/tls version can be negotiated. I do mandatory tls on my servers too, but not globally. Just for selected rcpt-domains/next-hops
