So it sounds like your box at relay-2.lctn.org is rejecting some messages destined for your users that are coming from the server at mail.svtv.com where the senders are @mail.svtv.com. If that is correct then there should be logs on your relay-2.lctn.org that explains why it rejected the message. Perhaps it is malfunctioning, misconfigured, or perhaps the mail.svtv.com has had some DNS issues though according to their SOA serial they have not made any DNS changes since November 12th. The logs on mail.svtv.com may also contain the exact rejection message from relay-2.lctn.org during the message delivery attempt. Logs are key here unless you have access to the mail.svtv.com server to run tests. -----Original Message----- From: tclug-list-bounces at mn-linux.org [mailto:tclug-list-bounces at mn-linux.org] On Behalf Of Raymond Norton Sent: Tuesday, December 01, 2009 12:55 PM To: TCLUG List Subject: [tclug-list] openspf message 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.
