限制要通過Java Mail從unix裝箱機本身發送的電子郵件

Question

我有下面的java程序，該程序用於通過java Mail API成功發送郵件，現在我的程序已部署在名為lonabc1123 unix機器上，並且此unix框具有ip 11.111.11.11 ，現在我想在此限制某些內容，那就是Java郵件僅在程序在此unix框itsef（lonabc1123）上運行時才發送，現在任何人都可以從此unix框之外發送郵件，我的意思是有人可以從其他unix框機發送郵件。

所以請告知我我知道這封郵件是從名為lonabc1123的IP地址為11.111.11.11的unix盒式計算機發送的，除此之外，沒有人可以從任何其他計算機發送郵件，所以我該如何扭曲下面的代碼，以便郵件可以僅從一個具有IP 11.111.11.11的lonabc1123的Unix框發送，我可以進行基於IP的檢查嗎，在發送郵件之前我將檢查IP，請告知

static String smtpHost = "11.162.90.80";
static String mailSmtpPort = "1965";
static String mailTo[] = {"ena@abs.com" };
static String mailCc[] = {"ena@abs.com" };
static String bccAddress[] = null;

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



    postEmail(mailTo, mailCc, "k",
            "testSubject", "Body123", smtpHost , mailSmtpPort);


}  



public static  void postEmail(String mailTo[], String mailCc[], String from, String subject, String text, String smtpHost, String mailSmtpPort ) throws Exception, DocumentException, IOException {
    try {
        Properties properties = new Properties();
        properties.put("mail.smtp.host", smtpHost);
        properties.put("mail.store.protocol", "imaps");
        properties.put("mailSmtpPort", mailSmtpPort);
        //obtaining the session
        Session emailSession = Session.getDefaultInstance(properties);

        //Enable for debuging 
        emailSession.setDebug(true);

        Message emailMessage = new MimeMessage(emailSession);


        if(mailTo!= null){
            InternetAddress[] addressTo = new InternetAddress[mailTo.length];
            for (int i = 0; i < mailTo.length; i++) {
                addressTo[i] = new InternetAddress(mailTo[i]);
            }
            emailMessage.setRecipients(RecipientType.TO, addressTo);
        }

        InternetAddress[] addresscc = new InternetAddress[mailCc.length];
        for (int i = 0; i < mailCc.length; i++) {
            addresscc[i] = new InternetAddress(mailCc[i]);
        }
        emailMessage.setRecipients(RecipientType.CC, addresscc);

         emailMessage.setFrom(new InternetAddress(from));
         emailMessage.setSubject(subject);

         emailMessage.setContent(text, "text/html");


          //Create the message part
        BodyPart messageBodyPart = new MimeBodyPart();
        messageBodyPart.setContent(text, "text/html");

               messageBodyPart.setText(text);

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

          //  attachment part
             MimeBodyPart attachPart = new MimeBodyPart();
             String filename = "c:\\swap.xls";





            multipart.addBodyPart(attachPart);
           // Send the complete message parts
            emailMessage.setContent(multipart);


      Transport.send(emailMessage);
    }    catch (AddressException e) {
        e.printStackTrace();
    } catch(MessagingException messagingException) {
        messagingException.printStackTrace();
        throw new Exception(messagingException.getMessage());
    }
}

您試圖將端口更改為1965，但是使用的屬性錯誤： properties.put("mailSmtpPort", mailSmtpPort);

正確的屬性是： properties.put("mail.smtp.port", mailSmtpPort);
