Question

我第一次使用Java Mail API而且我无法正常工作。我的服务器需要身份验证，所以我不得不使用它。我一直收到以下错误：

> 250-PIPELINING 250-SIZE 40960000
> 250-ETRN 250-STARTTLS 250-AUTH PLAIN

正如您所看到的，我正在收到“身份验证成功”消息，但随后它就会在“AuthenticationFailedException”上将其踢出去。我很难过......

以下是来源的相关部分：

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();          
      }

任何建议都会非常感激......

我把它改成了

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....");

并且有效
