Signing at the first MTA seems a bit stronger but you are right that
TLS can also be used.

But it seems the problem remains that:
- there needs to be a critical mass of actual deployments (without it
  one cannot refuse non TLS inbound or whatever other scheme is chosen)
- there needs to be an acceptance of certificates more costly than
  self-signed which a spammer can keep on generating like for domains.
