What hostname do you use on your computer?

[Knute Johnson]

What name do you give your computer?  I just installed FC6 and set my 
hostname to knute.sagebrush.frazmtn.com.  My gateway router is 
sagebrush.frazmtn.com and I used my name for this computer.  I've run 
into a couple of snags though.  Since knute.sagebrush.frazmtn.com 
doesn't have a DNS entry anywhere I can't relay mail through remote 
servers.  If I set my computer to localhost.localdomain then I can relay 
mail just fine.  What do you do if you don't have a fixed IP?

Thanks,
