how to route the request to Exchange server
Let s say at the Registrar (GoDaddy.com) we have the following records:
Host record (A) = mail.company.com 22.214.171.124
MX record= mail.company.com
PTR = 126.96.36.199 points to mail.company.com
When external users send us an email, in order to route their emails from our public interface to the exchange server mailbox, how is the CISCO router or the firewall configured?
Can someone writethe commands here? I believe all it requires is NAT commands, if I am not wrong.
