Properties   props   =   new   Properties();   
  props.put("mail.smtp.host","smtp.163.com");   
  props.put("mail.smtp.auth","true");   
  props.put("mail.smtp.user",   "[email protected]");     
  props.put("mail.smtp.password",   "0");     
  //下面的Sessioni要验证   
  Session   session   =   Session.getInstance(props,   new   PopupAuthenticator("[email protected]",   "0")   
    
  PopupAuthenticator类:   
  import   javax.mail.Authenticator;   
  import   javax.mail.PasswordAuthentication;   
  public   class   PopupAuthenticator   extends   Authenticator   
  {   
  String   username=null;   
  String   password=null;   
    
  public   PopupAuthenticator(String   user,   String   pass)   
  {   
  username   =   user;   
  password   =   pass;   
  }   
    
  protected   PasswordAuthentication   getPasswordAuthentication()     
  {   
  return   new   PasswordAuthentication(username,   password);     
  }     
  }
