symptom When sending an email from my outlook server using sendEmail, I keep getting a connect error. (101145)

ERROR [110 ms] [11:40:53.546]
Wrapped javax.mail.MessagingException: Could not connect to SMTP host: 192.168.1.12, port: 25;
nested exception is:
java.net.SocketException: Permission denied: connect

The code for sendEmail is as follows.

function sendEmail($emailSubject, $emailBody) {
      var $host = "192.168.1.12";
      var $port = 25;
      var $username = "";
      var $password = "";
      var $isSSL = false; // set to true if you use SSL
      var $mailer = new Packages.net.sf.sahi.ant.Mailer($host, $port, $username, $password, $isSSL);
      var $from = "sahi_test@example.com";
      var $to = "sahisupport@example.com";
      $mailer.send($from, $to, $emailSubject, $emailBody);
}

sendEmail("Mail from Sahi", "Script Run");

We do not need authentication and the server can be connected via telnet.
