当我使用javamail将回复邮件发送到Outlook帐户时，为什么回复邮件会作为附件发送？

Question

我试图在很多方面使用Outlook帐户和javamail api在同一个线程中获得回复，但是我无法在同一个帖子中获得回复而不是我作为附件。我试图复制整个内容并保存在当前消息中，即使然后我作为附件，也尝试更改内容处置作为内联仍然它不起作用你可以找到我尝试过的代码。

    Properties properties = new Properties();
    Session emailSession = Session.getDefaultInstance(properties,null); 
    store = emailSession.getStore("imaps");     
    store.connect(host,mailbox_username, mailbox_password); 
    folder = store.getFolder("Inbox");
    folder.open(Folder.READ_WRITE);
    Message[] unreadMessages = folder.search(new FlagTerm(new Flags(Flags.Flag.SEEN),false));
    if(unreadMessages.size()>0)
    {

        for (int i = 0; i < unreadMessages.length; i++) 
        {
            log.info("retriving message "+(i+1))
            Message message = unreadMessages[i]

            Address[] froms = message.getFrom();
            String senderEmailAddress =(froms[0]).getAddress();

            if(senderEmailAddress.endsWith("@gmail.com"))
            {
                subject = message.getSubject()
                log.info(message.getSubject())

            }
            else
            {   //reply to same mail here we need to reply to the message
                Message message2 = new MimeMessage(emailSession);  
                message2= (MimeMessage) message.reply(false);
                message2.setSubject("RE: " + message.getSubject());  
                //message2.setFrom(new InternetAddress(from));  
                message2.setReplyTo(message.getReplyTo());
                message2.addRecipient(Message.RecipientType.TO, new InternetAddress(senderEmailAddress));                        
                BodyPart messageBodyPart = new MimeBodyPart();  
                content = "some reply message"
                //multipart.addBodyPart(content);
                messageBodyPart.setText(content);                        
                Multipart multipart = new MimeMultipart("related");  
                multipart.addBodyPart(messageBodyPart);  
                messageBodyPart = new MimeBodyPart();                   
                //messageBodyPart.setDataHandler(message.getDataHandler());  
                //bodyPart.setDataHandler(new DataHandler(ds));
                //messageBodyPart.setHeader("Content-Type", "image/jpeg; name=image.jpg");
                //messageBodyPart.setHeader("Content-ID", "<image>");
                //messageBodyPart.setHeader("Content-Disposition", "inline");
                //messageBodyPart.addBodyPart(bodyPart);
                //msg.setContent(content);
                messageBodyPart.setDisposition(MimeBodyPart.INLINE);
                messageBodyPart.setContent(message, "message/rfc822");
                messageBodyPart.setDataHandler(message.getDataHandler());  
                // Add part to multi part  
                multipart.addBodyPart(messageBodyPart);  
                // Associate multi-part with message  
                message2.setContent(multipart);  
                Transport t = emailSession.getTransport("smtp");
                try {
                 t.connect(mailbox_username, mailbox_password);
                    t.sendMessage(message2, message2.getAllRecipients());
                } finally {
                   t.close();
                }
            }
        }
    }

“内联”与“附件”只是邮件阅读器的建议。许多人忽略了设备，或者无法内联显示所有内容类型。

如果您希望原始邮件的文本显示在回复邮件的正文中（例如，使用“>”缩进），则需要提取原始文本并将其重新格式化，将其添加到回复文本中，然后将新String设置为回复消息的内容。
