Providing TLSA records is only one half of the story. The sender has to
use them. Currently there is no way to force the sender to use my TLSA
records, is there?
(Though, I can force all senders to use TLS when talking to me, but I
can't force them to use my provided TLSA records and to do any
verification. And I do not have a chance to check, if they did, do I?)
