Question

尝试从Web应用程序发送邮件时遇到此异常：

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

我使用的代码如下代码。

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");

我还使用身份验证方法使用用户名和密码对用户进行身份验证。

只有在我进行身份验证时才能获得成功消息。当我进入名为transport.sen(message)的行时，我遇到了异常。

    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

有些邮件服务器可能会在客户端日志记录时自动将域名附加到用户名，但某些服务器不会，因此验证失败。

Try this code  :-

    protected PasswordAuthentication getPasswordAuthentication() {

 package com.test;


 public class Main {  

   public static void main(String[] args) {  
   String[] recipients = new String[]{"example1@gmail.com"};  //To

      System.out.print("Result"+new MailUtil().sendMail(recipients, bccRecipients,
