Question : Exchange 2010 Uninstall

I have had nothing but problems in configuring Exchange Server 2010. Once installed, can I flatten the machine and start again with Exchange server 2007? Will this cause any problems with AD? I'm sure the answer I'm looking for is out there in someone's head but there is very little documentation for Exchange 2010 and all answers relate to Exchange 2007.

My main problemwith Exchange 2010, is when I use Exchange Remote Connectivity Analyzer to test the outbound SMTP Connectivity, I receive:

Performing Outbound SMTP Test
 Outbound SMTP Test Failed
 Test Steps
 Attempting reverse DNS lookup for IP 10.10.1.1
 Reverse-DNS Lookup failed
 Additional Details
 IP Address 10.10.1.1 does not have a PTR record in DNS

I have confirmed that it exists in DNS and Exchange Remote Connectivity Analyzer doesn't provide any suggestions to resolve. I'd just as soon not uninstall 2010 but if I can't figure out where my problem lies, I think I will have to.

HELP please

Oh Joy - BT!  How come you are 8 hours behind if you are using BT?

You need to call 0845 600 7020 and ask them to add Reverse DNS.

Your MX record should not be a CNAME record.  It needs to be an A Record.
