well, my four domains (20 users, wow!) would reject that HELO...

are you sure Exchange was not going past the HELO phase? After all I
think exim will allow the session to continue even after a rejected
HELO.
I think rfc-ignorant.org should have the HELO argument check (A
record of helo -> IP address which implies the absence of _) in their
listing criteria. Why not push for that, I would support you (for
what it's worth).
(btw, I do not give the postmaster address in the RCPT error
messages, but the URL of a feedback form, this way a faulty server's
postmaster can contact me anyway)
