Bret Miller said:Yes, you should. But what happens if my almost-informed user decides to do it the old way? Do you blacklist my domain because a user decided to do things wrong?
I'm not sure how things could come to such a state - using SPF does not "blacklist domains"
Someone made a suggestion to blacklist based on SPF results. Problems were pointed out. The suggestion was withdrawn. The thread continues anyway.
Such is the Way of the Internet.
