2 Certificates required?
This is out of my realm of knowledge. Our email security appliance acts as our email gateway in that all outgoing and incoming go through the appliance. The appliance is mail.mydomain.org. Our email server itself is the same. mail.mydomain.org. The firewall forwards port 443 traffic to the email server for OWA access. We need a 2nd URL for our junk summary notifications. Before I purchase a certificate for unjunk.mydomain.org, will the email security appliance use both certificates? Or maybe I'm way off in that we really don't need the mai.mydomain.org certificate on the email security appliance?
