Of course you could. I explained how to do it, but (so far) you haven't done that -- hence all those replies from people being sceptical -- it would be really nice for those of us who are very curious about this problem if you would provide real evidence / data. Maybe there is some weird check by those servers: poffenberger.org. IN A 45.63.78.3 3.78.63.45.in-addr.arpa. IN PTR mail.poffenberger.org. and then say that poffenberger.org is not ok to use because its IP address does not point back to the same name? But that's just speculation without real data...
