Your reverse DNS doesn't match your forward DNS and your reverse DNS is "spammy" (66-237-146-66.static.pah.org). Have your ISP fix the rDNS to something unspammy.
HAHAHAHAHAHA. I just went and looked. Your "isp" is Punxsutawney Phil's hospital? :) Regards, Michael B.

Having and issue sending email to a single domain. Messages bounce back with: agnostic-Code: smtp;450 Client host rejected: cannot find your hostname, [66.146.237.66] I have both forward and reverse entries for our mail server (Exchange 2003) so I'm not sure why it can't find it. Am I missing something in the DNS setup? So far, this is the only domain I haven't been able to send email to. Thanks all! ******************************* John C.
