Java邮件验证错误

Question

我第一次使用Java Mail API，但无法正常工作。我的服务器需要验证，所以我不得不使用它。我不断收到以下错误：

> 250-PIPELINING 250-SIZE 40960000 
> 250-ETRN 250-STARTTLS 250-AUTH PLAIN 
> LOGIN 250-AUTH=PLAIN LOGIN 
> 250-ENHANCEDSTATUSCODES 250 8BITMIME

正如你所看到的，我得到一个“验证成功”的消息，但随后它踢我出去的“AuthenticationFailedException。”我难倒...

这里的源的相关部分：

properties.setProperty("mail.smtp.host", host);    
     properties.setProperty("mail.smtp.port", "25"); 


     properties.setProperty("mail.smtp.user", "myemailhere"); 
     properties.setProperty("mail.smtp.password", "mypasshere"); 
     properties.setProperty("mail.smtp.auth", "true");  
     properties.setProperty("mail.debug", "true"); 


     // Get the default Session object. 
     Session session = Session.getDefaultInstance(properties); 

     try{ 
     // Create a default MimeMessage object. 
     MimeMessage message = new MimeMessage(session); 

     // Set From: header field of the header. 
     message.setFrom(new InternetAddress(from)); 

     // Set To: header field of the header. 
     message.addRecipient(Message.RecipientType.TO, 
            new InternetAddress(to)); 

     // Set Subject: header field 
     message.setSubject("This is the Subject Line!"); 

     // Now set the actual message 
     message.setText("This is actual message"); 

     Transport transport = session.getTransport("smtp"); 
      transport.connect(host, 25, "myemailhere", "mypasshere"); 
      message.saveChanges(); 
      Transport.send(message); 



     // Send message 
     Transport.send(message); 
     System.out.println("Sent message successfully...."); 
     }catch (MessagingException mex) { 
     mex.printStackTrace();   
     }  

任何建议，将不胜感激...

Answer 1

我改成了

message.setText("This is actual message"); 

      Transport transport = session.getTransport("smtp"); 
       transport.connect(null,smtpUser,smtpPassword); //host, 25, "myemailhere", "mypasshere"); 
       message.saveChanges(); 
       transport.sendMessage(message,message.getAllRecipients()); 

//    Transport.send(message); 



      // Send message 
      // Transport.send(message); 
      System.out.println("Sent message successfully...."); 

它的工作
