Masses of rejections, not bounces. Indeed. If you had made it past
that test, the next test insists that the connecting IP have a PTR
record with a name matching the HELO name, which is also contrary to
RFC. IIRC, mail to postmaster is also refused on the same basis.
I'm of the opinion that mail administrators are entitled to implement
whatever policy they like for their own domains. Greg apparently has
very strong beliefs about what constitutes proper DNS, and isn't
interested in receiving email from anyone who doesn't conform to
them. That's his perogative.
