I have a domain constantly having problems sending to recipients within 
our WAN. All mail comes through our mailscanner, and is forwarded onto 
the domain. From the info I am receiving, some messages make it though, 
but others get bounced with the following message url:

http://www.openspf.org/Why?s=helo;id=mail.svtv.com;ip=216.235.172.10;r=relay-2.lctn.org

I am not seeing an error off-hand.

Any ideas?
