How to not receive any email at all
Sure, you could set up your mail server to enforce a security policy where any message with more than a certain number of 'Received' headers. But when that 'certain number' is '2', could you receive any mail at all?
(Yes, I actually saw this today: I sent off a quick email to postmaster@ but I'm not sure if it ever arrived or not :S)
Update 24 hours later: I haven't received a bounce, so maybe it did arrive. Hard to say.

If my mail setup (and that of the people emailing me) was simpler, sure.
Their server receives email from them, my server receives email from their server. That's two hops. What gets in the way is relaying... whether they have an internal set of relays (AV/Spam/logging), or whether it's relays on my side (I have two backup MXes, sometimes legit mail goes to them first.)
Personally, I definitely wouldn't feel comfortable blocking on something so arbitrary, even with a larger number... I've seen networks with 3-5 internal hops. Even scoring would be sketchy, there's no accounting for the strangeness of some setups.
