Re: AOL rejecting mail from IP's w/o reverse DNS ?

AOL says the PTR record needs to be assigned.  It doesn't specify it 
has to match the @domain.com in the MAIL FROM: header.  Wouldn't it be 
enough to make sure every IP address you announce has a PTR and 
matching A record?  Hasn't this been a requirement for MANY services 
for MANY years?

Requiring the PTR record to match the MAIL FROM: header would be horrific. 
There goes any hope of virtual hosting of mail accounts, i.e. one server 
with one ip handling multiple email domains.
