用JAVA程序进行邮件发送，出现一个错误，求解决方案？？？在线等！！！
本机与本机之间发送，可以正常发送。但是本机给126邮箱发送 则报错误！求解释，错误代码在下面！！[size=18px][/size]
属性文件：mail.properties
#邮件发送服务器地址
mail.smtp.host=smtp.126.com
#是否需要安全验证
mail.smtp.auth=ture
#邮件接收服务器地址
mail.pop.host=smtp.126.com
mail.uesr=admin@tjise.com
mail.password=admin


程序代码：
public class MAILUtils {
private static Properties prop=new Properties();
static{
try {
prop.load(Thread.currentThread().getContextClassLoader().getResourceAsStream("mail.properties"));
} catch (IOException e) {
  System.out.println("没有找到邮件服务器的参数");
e.printStackTrace();
}

}
//获取邮件服务器的Session对象
private static Session getSession(){
return Session.getInstance(prop, new MailAuthenticator(prop.getProperty("mail.user"),prop.getProperty("mail.password")));
}
//把字符串地址包装成Address对象
private static Address WraperAddress(String address){
Address ad=null;
try {
ad=new InternetAddress(address);
} catch (AddressException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return ad;
}
private static Address[] WraperAddress(String[] address){
int length=address==null?0:address.length;
Address[] ads=new Address[length];
for(int i=0;i<length;i++){
ads[i]=WraperAddress(address[i]);
}
return ads;
}
//根据参数创建一个HTML内容的的消息对象
private static Message createHTMLMessage(Session session,String fromAddress,String[] toAddress,String subject,String content){

//---------设置属性

}
//收件人
try {
