搭建个人搭建邮件服务器历程

一、java用qq邮箱授权发送邮件

https://blog.csdn.net/BO688/article/details/100628287

优点：可用
缺点：需要qq授权
希望:利用自己的域名发送

二、hmailserver

https://blog.csdn.net/BO688/article/details/104461740

优点：可以利用自己域名，发送到qq或者163等邮箱 ------用java代码和Foxmail都可以发送
缺点：有时会产生很多log日志文件，而且不能发送，重启之后可以发送出去
希望:不会出现堵塞和日志问题

三、James server 2.3.2.1

启动时一闪而过解决
james的问题
如何启动并且配置发送邮件
Ps:在foxmail测试时把stmp和pop填成 域名就好，填成stmp.域名反而出错
优点：foxmail可以使用域名发送
缺点：java 发送只能发送内网 ，发送外网就会出现下面的问题
550 repay deny（网上找到是需要开启stmp验证）
就是 535 认证失败（但是开启验证就通过不了）
希望:能访问外网

四、腾讯企业邮箱

到了这里感觉是又回到了最初的起点…
这里感觉是腾讯那里用域名发送了qq邮件…
但是终归实现了我的要求…
缺点：需要注册企业邮箱
下面贴一下自己的修改后的代码
这个是一些上面链接代码的修改封装

private static String emailRegular = "^\\s*\\w+(?:\\.{0,1}[\\w-]+)*@[a-zA-Z0-9]+(?:[-.][a-zA-Z0-9]+)*\\.[a-zA-Z]+\\s*$";//校验邮箱是否正确

    public static boolean validEmail(String emailAddress) {//判断返回对错
        return Pattern.matches(emailRegular, emailAddress);
    }
    private static String fromMailAddress = "****@****88.cn";//发贱人邮件地址
    private static String name = "admin";//自己名字
    private static String fromMailPwd = "******";//密码
    private static String fromMailSMTPHost = "smtp.exmail.qq.com";//stmp服务器
    private static String smtpPort = "465";//端口
    private static Properties setProperties(String debug) {
        Properties properties = new Properties();//配置
        properties.setProperty("mail.transport.protocol", "smtp");
        properties.setProperty("mail.smtp.host", fromMailSMTPHost);
        properties.setProperty("mail.smtp.auth", "true");
        properties.setProperty("mail.smtp.port", smtpPort);
        properties.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");//变种协议
        properties.setProperty("mail.smtp.socketFactory.fallback", "false");
        properties.setProperty("mail.smtp.socketFactory.port", smtpPort);
        properties.setProperty("mail.smtp.ssl.enable", "true");
        properties.setProperty("mail.debug", debug);
        return properties;
    }
    private static Session setSession(boolean debug) {
        Properties properties = setProperties(String.valueOf(debug));
        Session session = Session.getInstance(properties);
        session.setDebug(debug);
        return session;
    }
    private static Message setMail(Session session, String[] toEmailAdresses,String[] names, String emailTitle, String emailContent) throws Exception {
        MimeMessage message = new MimeMessage(session);//获得邮件
        message.setFrom(new InternetAddress(fromMailAddress, name, "UTF-8"));//设置发件人

        setallRecipients(message,toEmailAdresses,names);
        message.setSubject(emailTitle);//标题
        message.setContent(emailContent, "text/html;charset=utf-8");//内容
        message.setSentDate(new Date());//发送时间
        message.saveChanges();//保存
        return message;
    }
    private static void setallRecipients(MimeMessage message,String[] mailaddress,String []name)throws Exception{

        for(int a=0;a< mailaddress.length;a++){//把收件人邮箱数组加入其中
            System.out.println(mailaddress[a]);
            if(mailaddress[a]!=null)//判断是否为空
            message.addRecipient(Message.RecipientType.TO, new InternetAddress(mailaddress[a], name[a], "UTF-8"));

        }

    }
    public static boolean sendEmail(String[] toEmailAdress,String[] name, String emailContent, String emailTitle,boolean debug) {//地址，对方的名字，内容，标题，debug
        Session session = setSession(debug);
        try {
            Message message = setMail(session, toEmailAdress,name, emailTitle, emailContent);
            Transport transport = session.getTransport();
            transport.connect(fromMailAddress, fromMailPwd);//链接
            transport.sendMessage(message, message.getAllRecipients());//发送
            transport.close();
        } catch (Exception e) {
            e.printStackTrace();
            for(String E :toEmailAdress){
                System.out.println("toEmailAdress = " + E + ", emailContent = " + emailContent + ", emailTitle = " + emailTitle + ", error = " + e.getMessage());
            }

            return false;
        }
        return true;
    }

相关调用

@RequestMapping("/mail")
    public void mail(HttpServletRequest request, HttpServletResponse response) throws IOException {
        String next;
        boolean checkmail=true;//默认邮箱格式正确
            int i;
            String address[]=new String[5];//限制最多发送5个
            String inputname=request.getParameter("name");//判断前端是否设置名字
            String name[]={inputname,inputname,inputname,inputname,inputname};//这里需要和邮箱地址一样对应个数 对方名字
            String first=request.getParameter("receiver");//获得第一个邮箱地址
        if(first!=null&&first!=""&&validEmail(first)){//判断
           address[0]=first;
        }else{
            checkmail=false;
        }
            for (i=1;i<=4;i++){/*设置下一个发送对象，从第二个开始*/
            next=request.getParameter("receiver"+i);
            if(next==null||next==""){break;}/*循环非null的*/
            else {
                if(validEmail(next)){
                    address[i]=next;
                }else{
                    checkmail=false;
                }

            }
            }

        if(!checkmail){//判断是否出现格式错误
            response.getWriter().println("邮箱格式错误");
        }
        if( sendEmail(address,name,"hello","hello",true)){
            response.getWriter().println("已发送");
        }else {
            response.getWriter().println("发送失败");
        }


        response.setHeader("refresh", "3;url=mailhtml");
        response.getWriter().println("
三秒后跳转......");
