我在我们的域名上build立了SPFlogging，我不确定我应该使用什么SPFlogging。
我们有Exchange 2013设置发送使用我们的电子邮件过滤公司作为一个智能主机，他们的主机是最新的主机出现在电子邮件的标题，但也提到在头是我们自己的服务器 – 什么我们的SPFlogging应该如何？
我从我们公司发送了一封电子邮件到我的个人iCloud帐户，这里是标题：

最简单情况下的SPFlogging被目的地用作validation“什么服务器被允许直接与我联系并发送声称来自给定域的电子邮件”的手段，它可能已经穿越了几个跳跃事先没有关系。
像： company.com. IN TXT "v=spf1 a:smtp001.apm-internet.net" company.com. IN TXT "v=spf1 a:smtp001.apm-internet.net"
Smarthost smtp001.apm-internet.net可能会旋转IP，您应该要求您的提供者为您提供他们在其smarthost服务器上使用的IP范围。 没有它，你不能克里特“完美”的SPF。
应该是什么工作
company.com. in TXT "v=spf1 mx a:smtp001.apm-internet.net/24 ~all"
