	/>

<!--- Set up the SMTP server settings. --->
<cfset smtpSettings = {
	server="smtp.gmail.com",
	username="ben@bennadel.com",
	password="****************",
	port="465",
	usessl="true"
	} />

	Send out the email to a non-existent address. Here, we are
	going to use a personal GMail account in conjunction with
