Reading the post
Re: [cobalt-users] 554 Error DSN: Service unavailable
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.
Paul
