Correct. In fact, if you ever sent email to somebody @AOL.COM, you'd know
that unless you have PTR record (and that name properly matches back to ip
with direct A record), you'd not be able to get through their filters.
I'm a little confused now. postmaster.aol.com says they will reject any
connection w/o a PTR. However, A few weeks back this came up and it was
revealed that what they do is check for the existence of a PTR but not
whether it matches anything. If a PTR is found to not exist they then
don't out right block it but just treat the mail negatively.
They haven't said how the negative treatment works but I can confirm
that it is possible to successfully send mail to an aol recipient
without having a PTR record.
Perhaps this stricter checking is fairly new, within the last few weeks?
