Steven
   You need to talk to interliant, you have reverse setup on your raq 
   (it does this by itself by default unless you tell it not to )
   However interliant's nameserver  isn't pointing to your raq .....

   One thing you should look at tho, in DNS settings in the controll
panel, you should make sure you have exactly ONE reverse snd record per IP
address, the raq2 adds a reverse address everytime you add a domain name
unless you uncheck 'automatic reverse domain generation' , unfortunatly,
this is kind of a stupid default....

Name:    cameleon.net     <-- reverses to a different domain name ;)
Address:  209.235.50.172

*** ANS01.SAGENETWORKS.COM can't find

They need more glue here -/
