The standard Crestron email module uses port 80 and you can't change it. There are a few others available at Yahoo that allow virtually any port.
If it's a matter of changing the WAN port for the email, I faced the same issue with HAI's touchscreen where it only allowed port 25 for email sending.
MikroTik router with Chris' help, provided solution.
Here is the code for it:
/ip firewall nat>
;;; Change Port for email
chain=dstnat action=dst-nat to-ports=2525 protocol=tcp src-address=192.168.0.151 dst-port=25 log=no log-prefix=""
