关键报错信息： Caused by: java.net.ConnectException: failed to connect to smtp.outlook.com/52.98.33.226 (port 465) from /:: (port 37434): connect failed: ETIMEDOUT (Connection timed out)

居然连接超时，代码和别人的一样啊。

解决方案：把端口改为587即可

case "outlook.com":
            SMTPHost = "smtp.outlook.com";
            SMTPPort = "587";
            break;

已经适配腾讯邮箱和outlook邮箱，也适配了g_mail邮箱，有遇到其他问题的，可以私信或者评论我
