FCrDNS only needs the reverse lookup to produce a name that maps to the 
IP[1].  Some sites will do this wrong, and you can't deal with all the 
ways they can do it wrong.  Just try to work with the places that do it 
right.  For my domain I have A records for georgeanelson.com and 
rapidxen.georgeanelson.com (for the day when I move servers and also 
have a new.georgeanelson.com), MX 0 georgeanelson.com., and rDNS 
rapidxen.georgeanelson.com.
