The owner of a domain need not authorize a reverse DNS PTR record in any
way, shape or form. If the netblock was owned, or the netblock owner
had delegated rDNS to a malicious customer, they could easily set rDNS
to whatever they wanted. Aol.com, paypal.com, ebay.com, chase.com ...

That is what has me worried.

But how is PayPal's DNS involved in this as at what point are the Paypal DNS

John, I think my last post answered that.
FWIW, also check out the SPF record:
nslookup -type=TXT email.paypal.com
Which allows postdirect.com as a mailer. In this case, it's not needed,
because they also allow SPF from the PTR records that match.
