Java 使用Greenmail作为开发smtp服务器

我使用greenmail作为开发邮件服务器。我的用例是1）在邮件服务器上发送电子邮件，2）另一个进程将使用IMAP继续查找邮件服务器，并通知是否有任何新的电子邮件

要实现第一步，请发送电子邮件 我使用Greenmail的以下命令设置smtp服务器

java -Dgreenmail.setup.test.all -Dgreenmail.users=test1:pwd1,test2:pwd2@example.com \
     -jar greenmail-standalone.jar

现在，当我使用java的普通API使用SMTP发送电子邮件时。它说电子邮件发送成功，但我在发送电子邮件的“收件人”地址上没有收到任何电子邮件。下面是发送电子邮件的源代码

public static void main(String [] args) {    
      // Recipient's email ID needs to be mentioned.
      String to = "abcd@gmail.com";

      // Sender's email ID needs to be mentioned
      String from = "web@gmail.com";

      // Assuming you are sending email from localhost
      String host = "localhost";

      // Get system properties
      Properties properties=new Properties();

      // Setup mail server
      properties.setProperty("mail.smtp.host", host);
      props.put("mail.smtp.port", "3025"); //TLS Port
       props.put("mail.smtp.auth", "true"); //enable authentication
       props.put("mail.smtp.starttls.enable", "true");

      // Get the default Session object.
      Authenticator auth = new Authenticator() {
        //override the getPasswordAuthentication method
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(fromEmail, password);
        }
    };
Session session = Session.getInstance(props, auth);

      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");

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

你能帮我找出我做错了什么吗？ 1） 我们真的可以用绿色邮件发送电子邮件吗

问候

Maulik

我发现我的代码有问题

问题是我的IMAP阅读器代码中的toAddress。我使用了错误的登录id和密码来访问localhost帐户

一旦我修复了它，我也开始在IMAP上接收电子邮件

下面是工作代码示例

1） TestEmail-通过SMTP发送电子邮件的邮件

public static void main(String[] args) throws Exception {

    Session session;
    String user = "test1";
    String password = "pwd1";

    String fromAddress = "test1@localhost"; // newlycreateduser@localhost
    String toAddress = "test1@localhost";

    // Create a mail session
    Properties properties = System.getProperties();
    properties.put("mail.transport.protocol", "smtp");
    properties.put("mail.transport.protocol.rfc822", "smtp");
    properties.put("mail.smtp.host", "localhost");
    properties.put("mail.smtp.port", "3025");
    properties.put("mail.debug", "true");
    properties.put("mail.smtp.localaddress", "127.0.0.1");
    session = Session.getInstance(properties, new Authenticator() {
        @Override
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication("test1", "pwd1");
        }
    });

    try {
        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress(fromAddress));
        message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(toAddress));
        message.setSubject("Email From my Greenmail");
        message.setText("Test Mail sent from My Greenmail!!");
        message.addHeader("X-THALES-ID", "1");
        message.addHeader("X-ROUTE-TO", "thalestest");
        message.addHeader("X-GROUND-TYPE", "GROUND");
        message.addHeader("X-ORIGINAL-FROM", "ambatltesttool");
        message.addHeader("X-EMBATL-ERROR", "");
        Transport.send(message);


        System.out.println("Email sent successfully from greenmail");
    } catch (MessagingException e) {
        e.printStackTrace();
    }
}

2） TestIMAP-不断读取本地主机帐户以检查新电子邮件

public static void main(String[] args) throws Exception {
        Session sessionIMAP;
        sessionIMAP = setupImap();
        while(true) {

            Store store = sessionIMAP.getStore("imap");
            store.connect("localhost", 3143, "test1@localhost", "test1@localhost");
            if (store.isConnected()) {
                System.out.println("IMAP is connected");
                Folder folder = store.getFolder("INBOX");
                if (folder != null) {
                    folder.open(Folder.READ_ONLY);
                    //folder.getMessage(1);
                    if(folder.getMessageCount() > 0) {
                        System.out.println("maulik - " + folder.getMessage(1).getSubject());
                    }
                    Message[] messages = folder.getMessages();
                    System.out.println("maulik messages.length---" + folder.getMessageCount());
                }
            } else {
                System.out.println("IMAP is not connected");
            }
            Thread.sleep(1000);
        }
    }

    private static Session setupImap() {
        System.out.println("in setupImap");
        Session session1;
        Properties props = new Properties();
        props.setProperty("mail.store.protocol", "imap");
        props.put("mail.imap.host", "localhost");
        props.put("mail.imap.port", 3143);
        props.put("mail.debug", "true");
        props.put("mail.imap.localaddress", "127.0.0.1");
        session1 = Session.getInstance(props, null);
        return session1;
    }
