Java Mail API異常

Question

嘗試從Web應用程序發送郵件時出現此異常：

com.sun.mail.smtp.SMTPSendFailedException: 550 5.7.1 Missing 
or literal domains not allowed

我正在使用下面的代碼之類的屬性。

Properties props = new Properties();
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.host", "smtp.verizon.net");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");

我還通過身份驗證方法使用用戶名和密碼對用戶進行身份驗證。

僅當我通過身份驗證時，我才會收到成功消息。 當我進入名為transport.sen(message)行時，出現異常。

    this is my full code..



try {

            MimeMessage message = new MimeMessage(session);
            message.setFrom(new InternetAddress(from));
            message.addRecipient(Message.RecipientType.TO, new InternetAddress(
                    to));
//          message.addRecipient(Message.RecipientType.CC, new InternetAddress(
//                  cc));
//          message.addRecipient(Message.RecipientType.BCC,
//                  new InternetAddress(bcc));
            message.setSubject("TEST...!!!!!!!");

             Multipart multipart = new MimeMultipart();

             BodyPart messageBodyPart = new MimeBodyPart();
             messageBodyPart
             .setText("Dear Sir, Mail Testing");
             multipart.addBodyPart(messageBodyPart);


             messageBodyPart.setText("Hao test");
            message.setText("Kader here");
             message.setContent(multipart);


             MailcapCommandMap mc = (MailcapCommandMap) CommandMap.getDefaultCommandMap();
                mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html");
                mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml");
                mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain");
                mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed");
                mc.addMailcap("message/rfc822;; x-java-content-handler=com.sun.mail.handlers.message_rfc822");
                CommandMap.setDefaultCommandMap(mc);
            Transport transport = session.getTransport();

            transport.connect();
            Transport.send(message);
            transport.close();


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

Answer 1

客戶端登錄時，某些郵件服務器可能會自動將域名附加到用戶名上，而某些服務器則不會，因此會導致身份驗證失敗。

Try this code  :-
