Have your reverse zones been delegated to you by your Internet provider? It is possible that the reverse zones aren't pointing to you, so it wouldn't matter if you updated your names servers. Go to dnsstuff.com and do a reverse lookup on your mail server's IP to see what name server responds. Most likely your ISP is hosting the reverse zone and doesn't have any information about your server. I had the same problem and had to contact AT&T to delegate the zone to me before I could fix it.

Although we have published the PTR record, it does not resolve. Our corporate site - vitalps.com (209.154.100.10) - does resolve properly. We use the same name servers for both sites. What am I missing? Thanks.

If you have a portion of a class C for example, your ISP may centralize the reverse zone and handle the updates for all of its customers who share that block. > -----Original Message----- > From: Ben Winzenz [mailto:[EMAIL PROTECTED]] > Sent: Thursday, April 11, 2002 9:54 AM > To: Exchange Discussions > Subject: RE: DNS > > > You make sure that you have a reverse lookup zone with a PTR > record for your > Exchange server. > > Ben Winzenz, MCSE > Network/Systems Administrator > Peregrine Systems > > > -----Original Message----- > From: Irfan Malik [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, April 10, 2002 11:44 PM > To: Exchange Discussions > Subject: RE: DNS > > Ben, how can I solve this. > > -----Original Message----- > From: Ben Winzenz [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, April 10, 2002 7:16 PM > To: Exchange Discussions > Subject: RE: DNS > > It doesn't appear that you have reverse DNS records for your Exchange > server.
