This is our policy and has been in effect for about a year now or more.
Notice the word "may" in it. We do not outright reject for no RDNS, but
we are critical of servers that do not have it. The reason we do not
reject outright is that DNS is not always reliable. So we only reject in
certain "situations" when we 1) Know a server does not and has never had
rDNS and 2) Are getting reports of spam coming from that machine.

I was just browsing my SMTP log and found this:
"America Online (AOL) and it's affiliated companies do not authorize the use of it's
proprietary computers and networks to accept, transmit, or distribute unsolicited bulk
e-mail sent from the internet. Effective immediately: AOL may no longer accept
connections from IP addresses which have no reverse-DNS (PTR record) assigned."
I found it interesting. Is this a policy of many MTAs?
