I am being told that my mail server is not giving out a proper name, so we keep being blacklisted, what setting in exchange 2003 should i change to resolve this. Error i am getting is <casvr002.childadvocates.ns #5.5.0 smtp;550-69.39.135.189 blocked by ldap:ou=rblmx,dc=comcast,dc=net>. I have been taken off of the blacklist then put back on 3 days later, thanks

You should probably review my dns configuration page.
http://www.amset.info/exchange/dnsconfig.asp

From the error above your SMTP banner is invalid.
The IP address 69.39.135.189 has no valid reverse DNS, so that is at least two settings that are incorrect.

You don't set the reverse DNS. Your ISP does. The reverse DNS is attached to the external IP address of the Exchange server.
