Well, at the moment of HELO, I have the IP address of the machine
connecting, and what they say in helo. The only thing I have to check
the helo data against is the rDNS of the IP address making the
connection.
But, I'm not hugely interested in arguing about it; my only point was
that, from my point of view, a reasonably configured mail server, should
match all of helo data, forward DNS, and rDNS. I really don't care
which is the prime mover in this circumstance.
