this code is telling it to use port 80:
$WA_MailObject = WAUE_Definition("relay-hosting.secureserver.net","80","walt@classicpumps.com","","","");
if you want it to use 2525, edit that code to:
$WA_MailObject = WAUE_Definition("relay-hosting.secureserver.net","2525","walt@classicpumps.com","","","");
or edit the UE Interface to change the SMTP Server settings
