PCI Scan Failed

sorry guys this may not relate to you guys I added in the IP address for our main line last night into the SecurtyMetrics scanning, and the scan has failed. i have attached the results page screen shot. is this some thing relate to the firewall or the old mail server we had has expired license ? 

we are no using exchange any moe 

since we dont use the exchnage any more if i close port 10443 will it resolve the issues. 

please any help much appreciated.
