我想通过gmail服务器发送电子邮件.我已经输入了以下代码,但它在发送时卡住了.请问....

MailMessage mail = new MailMessage();

        mail.From = new System.Net.Mail.MailAddress("apps@xxxx.com");

        //create instance of smtpclient
        SmtpClient smtp = new SmtpClient();
        smtp.Port = 465;
        smtp.UseDefaultCredentials = true;

        smtp.Host = "smtp.gmail.com";            

        smtp.EnableSsl = true;

        //recipient address
        mail.To.Add(new MailAddress("yyyy@xxxx.com"));

        //Formatted mail body
        mail.IsBodyHtml = true;
        string st = "Test";

        mail.Body = st;
        smtp.Send(mail);

xxxx.com是Google应用中的邮件域.谢谢...
