Yeah, I've talked to their admin. He's sort of like me--Jack of all trades, master of none. Doesn't seem to know much more about SPF than I do, so he's not able to determine specifically why they're blocking us. He turned SPF filtering off temporarily, and our mail to him got right through--so it's definitely tied to SPF filtering somehow. I think their end is Exchange 2003.
By your description, the "none" may not be a problem. -----Original Message----- From: Ben Scott [mailto:mailvor...@gmail.com] Sent: Thursday, August 12, 2010 3:48 PM To: MS-Exchange Admin Issues Subject: Re: Any SPF Wizzes Out There?

For example, with the SMTP command: HELO na3sys009aog113.obsmtp.com For me, that name resolves to 74.125.149.209, which matches the IP address in the above. However, if I try to connect to that IP address on TCP/25, the TCP connection never comes up. I presume it's an "outbound only" configuration, and any incoming connection attempts are silently dropped at the network layer. Perhaps something is attempting to verify that the HELO name given actually leads back to an MX which identifies itself by that name. Since the connection is never made, it can't say one way or the other; hence "none". -- Ben NOTICE: Florida has a broad public records law.
