Haven't you just reinvented whitelisting? I think it's pretty likely that people will make lists of IPs known to be mail clients to keep down the filtering load, but there's still the problem that bad guys an sign up so you have endless compliance problems. Oh, and if you did that, how would MTAs check that an address of an incoming connection was on the list? That's the issue that started this discussion.
