It rules out all of us who are running servers on "non-commercial" accounts
where our ISP won't support the reverse DNS; where we have a dynamic IP
assingned from a pool. I have that problem with AOL - can't email my Dad any
more. AOL appears to have gone so far as to reverse DNS the first server in
the headers, which may be what's knocking me out because I SHOULD be routing
through the RR server for AOL, and it still bounces.
There are better ways to block spam. See spamassassin.
