Exactly. I guess the question is, should we build more sender verification into sendmail, on both the sending and receiving side?

It would seem like a nice feature for Sendmail, but do you think it is realistic to assume that everyone would upgrade? I know of many hosts which use "outdated" versions of Sendmail. Then you would be faced with the question of whether to only allow connections from the latest version of sendmail (with the sender verification), which would limit it's usefulness.
