Sign-up mail to my primary address produced the following at the server:

May 14 12:01:41 svc2 postfix/smtpd[15898]: NOQUEUE: reject: RCPT from unknown[208.65.201.77]: 450 4.7.1 Client host rejected: cannot find your hostname, [208.65.201.77]; from=<agent.ruby@amd.com> to=<MY MAIL ADDRESS> proto=ESMTP helo=<fusetalk.com>

Those connection attempts get denied because doing so nukes 99% of incoming spam without much load on the server and, frankly, all proper senders who know what they're doing have RDNS set up. DNS is not some new fancy thing.
