It's an even more dangerous assumption that misconfigured machines will be
allowed to "get away with" decidedly invalid input. Since the cost of spam
lies more with the receiver than the sender, it seems perfectly reasonable
to me for a receiving server to reject senders that aren't following the
rules. No shirt, no shoes, no service.
I also block senders who say "HELO they.org". Should I give a blanket
pass to anyone in the world who says they're me?

I think you guys are missing the point here. This was not a misconfigured
MTA. There was no provision with the supplied User Interface for the user
to change the HELO response; it was a standard installation. For that
matter, I never ever knew what our Sendmail server was sending for a
response, and the only way I could find out was to run a packet analyzer on
the receiving server. This is way beyond the average email administrator's
capability.
The fix that I implemented was a work around, and I don't know if it will
persist after the first configuration change using the supplied UI (Web
Interface).
