我现在是windows下使用goland, 程序再 wsl2中调试. 老是监听不起25端口

再 wsl2 里面执行 netstat -tunlop 返回下面

郁闷了, 再 docker 容器中运行也是一样的,这应该是有点问题.

listen tcp :25: bind: address already in use
或者
listen tcp :465: bind: address already in use

尝试用root权限启动呢，linux要求低位端口需要root权限。另外，直接在windows上面启动呢，wsl的网络过于复杂，我也不知道怎么排查

看着应该是代码的问题哦, 同时启动2个携程, 2个携程里面共用了 变量 instance ,而 instanceTls 没用到

		go smtp_server.Start()
		go smtp_server.StartWithTLS()
Jinnrry commented

确实代码有问题，已经修复了
