I disagree... although I realize in the war on spam, there will be some
innocent bystanders killed.

A mail server I've recently finished setting up for some semi high
traffic stuff (for me, anyway, probably nothing compared to what some of
the big boys run) still doesn't have a PTR record... getting the colo
provider to edit their zone files seems to be like pulling teeth.  :-)
