PGP Universal Server SMTP change on Build 15495

Hi,

   Need help changing the SMTP server from the default setting. So under System, Administrators, I setup a "send Daily Status Email" for the Admin account. When I click the send status now button and view the mail queue  I get a connection to the Cluster4.us.messagelabs.com server refused. I know it's my firewall blocking this, I don't want to create a new rule and open the traffic to this defailt SMTP server. Anyone know how I can change this so it can use my own SMTP server?

I am having the hardest time finding the configuration page for this. Do I need to do this as a command line on the server it self? Can someone please help me?

Thanks
