Server 2003 DC / Exchange 2003 all updates.  Users use Outlook 2003 for Client E-mail.
I have contacted Earthlink, AOL and Frontiernet and they all say my reverse DNS is not turned on right.

DNSSTUFF.com Reverse DNS test message:
Answer:
ip.ip.ip.ip PTR record: ip-ip-ip-ip.stkn.mdsg-pacwest.com. [TTL 38400s] [A=None] *ERROR* A record does not point back to original IP.

So, Cool there is the problem.. Ummmm Now How do I go about fixing this in Exchange 2003.

Well... it says it's the reverse DNS lookup not correct, so you need to fix your DNS, not Exchange.

Do you do your own external DNS?  then go to your DNS server and make sure forward and reverse entries are correct.

Reverse DNS entries are handled by the ISP who gives you your IP address.  Contact your ISP to set it up.
