I guess I'm confused as to why it's coming from this IP 216.119.112.51 when I've specified the MX record for precisionx.net to point to 65.110.77.72

If I do a reverse DNS >lookup for precisionx.net I get a valid PTR record back. Reverse DNS is different than forward DNS. Reverse DNS takes an IP and returns the host name (using a PTR record); forward DNS usually takes a host name and returns an IP (using an A record). >Received: from precisionx.net [216.119.112.51] by fpmamail.com with ESMTP > (SMTPD32-6.06) id A02C4790076; Fri, 04 Jun 2004 11:07:24 -0400 In this case, the E-mail came from the IP 216.119.112.51. That IP does not have a reverse DNS entry (see http://www.dnsstuff.com/tools/ptr.ch?ip=216.119.112.51 ). Since it does not have a reverse DNS entry, it fails the REVDNS test. -Scott --- Declude JunkMail: The advanced anti-spam solution for IMail mailservers since 2000.
