This type of error is often fixed within the queue lifetime of a message.
If TLS was working for a destination, and was misconfigured down, the
miscreant administrator should notice and bring it back.

If you're requiring TLS support from strangers who might never have
offered TLS, and expect delivery or an immediate bounce, we don't
yet support that.
