This is true. And if memory serves well, a connecting mail server does not
even need a valid PTR. I was a bit surprised, though, as I received mail
from both addresses, this one too:

Received: from www.roaringpenguin.com ([])

Hence, I was surprised; as some mail apparently goes out with the IP of the
roaringpenguin mail exchanger, and other mail apparently not. :)

I look forward to its implementation. :) Meanwhile, it remains a good idea
for roaringpenguin to get delisted at dynablock.easynet.nl.
