警告:主机名localhost不parsing为地址

我在我的Debian盒子上使用了iRedmail。 我试图使用Outlook的电子邮件客户端,但我得到这个错误,无法解决它。

你的问题是,Outlook在执行EHLO时将自己标识为从“localhost”进行连接,在Postfix机器上,“localhost”(从Outlook机器的angular度来看是corerct)不能parsing为[my-ip],而是127.0.0.1这是不是IP后缀正在看到连接来自。 你需要重新检查你的Windowsconfiguration,而不是你的Linux。

为了100%确定这一点,你应该tcpdump端口25来查看EHLO localhost行。
