Foxmail 自己下载

修改服务器配置

1.点击工具->服务器设置

图片设置什么的推荐使用这位大佬的：https://www.cnblogs.com/xuyou551/p/8126279.html

2.代码

实现网易163邮箱发送邮箱

1.注册个163邮箱

2.登录163邮箱 -> 设置 -> PoP3/SMTP/IMAP -> 点击开启 IMAP/SMTP服务 -> 按照他的指示就行然后获取授权码 AAAAAAAAAA

代码建议异步跑

CompletableFuture.runAsync(() -> {
            // 邮箱信息取配置表中邮箱信息
            try {
//                MailUtils.sendMail(true);
                MailUtils.sendMail(false);
            } catch (MessagingException e) {
                e.printStackTrace();
            }
        });
