Reading the post

earlier this morning, I took a look at my etc/hosts file.
 
 I have not manually edited the file, ever! So this is the way
 it was created when setting up the RAQ2.
 
 etc/hosts currently is ....
 127.0.0.1	localhost
 64.135.71.133	raq2.agilitysystems.com 	# main interface
 
 
 Should it be like this?....
 127.0.0.1	localhost
 64.135.71.133	raq2.agilitysystems.com		# main interface
 64.135.71.130 	ns1.agilitysystems.net	ns1 	#primary dns
 64.135.71.131	ns2.agilitysystems.net	ns2 	#secondary dns
 
 (and should there be spaces or tabs between the line segments?)
 
 Are there any other files (and which ones) that I should check to see what
 else is missing that prevents email to aol.com and mail refusal 
 to the site
 www.wordsup.com
 
 TIA.
