nametlg

公司的邮件服务不是我弄的，最近给国外发邮件 还有hotmail的邮件总是被退信，公司的服务器是固定Ip的 用的是WINMAIL的邮件服务器。
情况是这这样的：
Hi. This is the smtp delivery program.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

=====================================================

您好！
您的邮件不能成功的递送到指定地址。这是一个永久的错误，因此不得不放弃继续递
送。

你的ip被block了。去http://www.spamhaus.org  查询一下。然后申诉。很简单的。然后找一个大型的如网易之类的邮箱等着收信。然后就是等着解禁。

做一个邮件服务器，最好是固定IP的，还要做一个反向域名解析！很多邮件服务器都要求这样，特别是国外。
