I suppose it wasn't clear that I intended to speak more generally of
checks at rcpt time vs mail time, rather than specifically on the issue of
checking the sender address validity.

I shouldn't have said "that check", but probably used "such checks".
Perhaps the use of "misbehaving" was ill-advised too, substitute
"problematic" instead.
