I am putting a new mail server in for a company and they are using a Cisco device which has ASDM 6.1 for ASA. The firewall was setup by someone else who is out of contact and I have never used this device before. I need to have ports 25 and 443 open and allowed through to the server for mail and OWA. The server is on the internal network (not the dmz) and I have an external static ip address. Can someone give me the steps I need to take to get this done? I don't want to change any of there existing rules or I would set it back to default and run the wizard. Any help would be greatly appreciated.
