我正在使用 javamail api 制作一个自动发送电子邮件 java 项目。当我使用 smtp.gmail.com 主机发送此邮件时，它可以工作。但是当我使用我自己的主机服务器 mail.sitename.com...它显示异常...我的用户名和密码是正确的。请任何人帮助我解决这个问题......例外是： -

得到了解决方案....有时 javax.mail.AuthenticationFailedException: 535 authentication failed (#5.7.1) 当主机未使用代码对用户进行身份验证达到限制时会发生...因为我打电话给主机发送邮件到 approax一个程序运行 500 个用户。因此 sendMail() 调用了 500 次并让服务器挂起。因此它阻止了我对编码站点的身份验证，但可以使用浏览器访问。当我创建一个新帐户时，我找到了解决方案，然后在编码中我创建了一个线程，发送邮件（）将以 10 秒的间隔被调用，然后一次发送给 100 个用户。主机是从一个网络解决方案电子邮件登录的。希望我能给某人解决此类问题。:)

在一个项目中，我需要发送一封带有附件的电子邮件，该附件包含可以在不同客户端计算机上生成的测试结果，我使用了以下属性和代码（这些属性被转换为代码中提到的 Settings 对象中的字段以下）

==================== Properties Section ====================
! Default Properties for the Email section of the project - others omitted

! The email provider may or may not require authentication - make sure to make the appropriate choices on the client
EmailSender = aUser@gmail.com
EmailPassword = unEncriptedPassword
EmailRecipients = me@gmail.com,she@gmail.com,you@yahoo.com,andAnyBodyElse@aol.com
EmailHost = smtp.gmail.com
EmailPort = 587
EmailAuthenticationRequired = true

==================== Code Section ====================
public class Email {

   public static void sendMail(String subject, String messageBody, String fileName) throws MessagingException {

      DDTSettings settings = DDTSettings.Settings();
      final String sender = settings.emailSender();
      final String password = settings.emailPassword();
      String[] recipients = settings.emailRecipients().split(",");
      String host = settings.emailHost();
      String port = settings.emailPort();
      boolean emailAuthenticationRequired = settings.emailAuthenticationRequired();
      String trueOrFalse = emailAuthenticationRequired ? "true" : "false";
      Properties properties = System.getProperties();
      Session session;

      // Use system properties and add some related to email protocol
      Properties props = System.getProperties();

      // Setup mail server
      props.setProperty("mail.smtp.host", host);
      props.setProperty("mail.smtp.port", port);
      props.setProperty("mail.smtp.ssl.enable", "false");
      props.setProperty("java.net.preferIPv4Stack","true");
      props.setProperty("mail.smtp.starttls.enable", trueOrFalse);
      props.setProperty("mail.smtp.auth", trueOrFalse);

      // Create a session with or without authentication object as indicated in the settings.
       if (emailAuthenticationRequired) {
           Authenticator auth = new Authenticator() {
               protected PasswordAuthentication  getPasswordAuthentication() {
                   return new PasswordAuthentication(sender, password);
               }
           };
           session = Session.getDefaultInstance(props, auth);
       }
       else {
           props.setProperty("mail.smtp.user", sender); // Needed if not authenticating
           props.setProperty("mail.smtp.password", password); // Needed if not authenticatin 
           session = Session.getDefaultInstance(props);
       }

       // Setup the message in two parts, body and attachment then send it
      try{
         // Create a default MimeMessage object.
         MimeMessage message = new MimeMessage(session);

         // Set From: header field of the header.
         message.setFrom(new InternetAddress(sender));
         //message.setReplyTo({new InternetAddress(sender)});

         // Set recipients
         for (int i = 0; i<recipients.length; i++) {
            message.addRecipient(Message.RecipientType.TO,
                  new InternetAddress(recipients[i]));
         }

         // Set Subject: header field
         message.setSubject(subject);

         // Create the message part
         BodyPart messageBodyPart = new MimeBodyPart();

         // Set the body of the message as html content
         messageBodyPart.setContent(messageBody, "text/html");

         // Create a multipart message
         Multipart multipart = new MimeMultipart();

         // Set text message part
         multipart.addBodyPart(messageBodyPart);

         // Part two is attachment
         messageBodyPart = new MimeBodyPart();
         DataSource source = new FileDataSource(fileName);
         messageBodyPart.setDataHandler(new DataHandler(source));
         messageBodyPart.setFileName(source.getName());  
         multipart.addBodyPart(messageBodyPart);

         // Place the entire kit & caboodle in the message
         message.setContent(multipart );

         // Send message
         Transport.send(message);
      }
      catch (MessagingException e) {
         e.printStackTrace();
      }

   }

如果您使用 gmail 帐户发送电子邮件 (SMTP)，请确保您在 application.properties 文件中具有正确的电子邮件密码，并启用此设置 以允许您的 gmail 帐户使用不太安全的应用程序。
