Uncertainty about what?  You can be 100% certain that if you've
published your policies in SSP, any receiver who cares to know about
them can look them up.

No matter what you do, you don't get certainty about their internal
filtering practices any more than you get certainty about whether
their internal delivery practices use POP, IMAP, or Baudot paper tape.
