SimpleMail的一个问题

Question

请教各位大侠，我在Test类中写了一个SimpleMail发送邮件的方法，在main()方法中调用邮件发送成功
但是在servlet中调用就出错呢？
public class Test {
public static void main(String[] args) {
String from="[email protected]";
String to="[email protected]";
String subject="测试";
String msg="你能收到吗？";
Test test=new Test();
test.sendMail(from, to, subject, msg);
}
public  void sendMail(String from,String to,String subject,String msg){
SimpleEmail email = new SimpleEmail();
email.setHostName("smtp.163.com");
email.setAuthentication("colour_ll", "******");
email.setCharset("utf-8");
try {
email.setFrom(from);
email.addTo(to);
email.setSubject(subject);
email.setMsg(msg);
email.send();
System.out.println("邮件发送成功！");
} catch (EmailException e) {
e.printStackTrace();
System.out.println("邮件发送不成功！");

}
}}public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
                        String from=request.getParameter("from");
String to=request.getParameter("to");
String subject=request.getParameter("subject");
String msg=request.getParameter("content");                        Test test=new Test();
        test.sendMail(from, to, subject, msg);
}
错误信息：

所有的易网免费邮箱已经在2007-11之后取消了pop3服务，主要是为了屏蔽垃圾邮件，用sina或者yahoo邮箱目前应该还可以

我用main方法测试过了呀，我的hotmail确实收到了163的邮件。
