出现：“javax.mail.SendFailedException: Sending failed; nested exception is: javax.mail.AuthenticationFailedException ”是什么原因？？？

你用的服务器需要SMTP认证
定义认证类
public  class  SmtpAuthenticator  extends  javax.mail.Authenticator
           {
                       String  usr=null;
                       String  pw=null;
                       public  SmtpAuthenticator(String  user,String  pass)
                       {
                                   this.usr  =  user;
                                   this.pw  =  pass;
                       }
                       protected  javax.mail.PasswordAuthentication  getPasswordAuthentication()
                               {
                                       return  new  javax.mail.PasswordAuthentication(usr,  pw);
                               }
           }
然后使用
//用户认证过程
                       SmtpAuthenticator  sa  =  new  SmtpAuthenticator(username,password);
                       Session  sess=Session.getInstance(props,sa);
                       sess.setDebug(false);
