<%
String from="myname@mydomain.com";
String to="recipient@recipientdomain.com";
try{
SmtpClient client = new SmtpClient("203.197.175.3"); //This is the SMTP server address
client.from(from);
client.to(to);
PrintStream message = client.startMessage();
message.println("To: " + to);
message.println("Subject: Sending email from JSP!");
message.println("This was sent from a JSP page!");
message.println();
message.println("Cool beans! :-)");
message.println();
message.println();
client.closeServer();
