TYPICALLY, yes. BUT, PTR records come from the ISP. So they need to do that part. Everything else is on you.

I'm about 20 minutes from Punxsy Phil =) Our hospital and Punxsy hospital are on the same ISP. But here is where my lack of DNS skillz comes in to play. Shouldn't any dns queries for my mail server come to MY dns server, regardless of who my ISP is? Or am I not understanding how that lookup works? Thanks! And Phil says there will be 6 more weeks of winter! =) ******************************* John C.

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? J 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.
