Interesting. When I look up the IP address, the rDNS returns the correct answer:
% host 44.76.7.7 7.7.76.44.in-addr.arpa domain name pointer mailman.ampr.org.
What happens when you look it up on your host? - Brian

As I said, time will fix that - it's a question of when the old address expires out of DNS caches and the new one is learned.
DNS should be updated by now. Have you set reverse DNS accordingly?
That's likely ok by now, since the DNS TTL was an hour. But until the email reputation of the new address builds, it's still quite possible that messages will be marked as spam by some overzealous anti-spam algorithms.
This is not the case. I run this mail server. It simply checks if HELO information is valid.
