rfc 1912:

2.1 Inconsistent, Missing, or Bad Data

   Every Internet-reachable host should have a name.  The consequences
   of this are becoming more and more obvious.  Many services available
   on the Internet will not talk to you if you aren't correctly
   registered in the DNS.

it's should, even not SHOULD but it says so. It even means that others are
not required to communicate with you if you don't have reverse DNS.
