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?
