I do not think it is a requirement by RFC, and I also think it is strictly harmful to force the connecting IP address to resemble the hostname, for example a pool of machines called smtp[1-9].example.com going out via a single IP address. Calling them all smtp.example.com is (a) not true and (b) frustrates debugging.
