Question

最近我发现我不能再使用我在“发件人：”标题中选择的任何电子邮件发送电子邮件，除非该域名具有匹配的TXT / SPF记录。否则，一些垃圾邮件代理机构会将您的IP＃标记为顽皮。

所以，这就是我的想法 - 有一个功能可以检查电子邮件地址域名是否具有匹配的共享相同IP号码的TXT记录。

基本上，我们正在寻找这个TXT记录：

> v=spf1 include:_spf.google.com ip4:199.###.184.26 ~all

并试图查看该IP号码是否与我们的号码匹配。

所以结果可能如下所示：

来自：mark@matchingIpNumber.com

来自：marky edwards \＆lt; mark@matchingIpNumber.com>

发件人：apache@serverDomainName.com \ r \ n回复：mark@noMatchingIpNumber.com

来自：marky edwards \＆lt; apache@serverDomainName.com> \ r \ n回复：标记爱德华兹   \＆LT; mark@noMatchingIpNumber.com>

我的问题：有没有其他人遇到过这个问题，如果有的话，它是如何处理的？

这是我正在考虑解决这个问题的php函数：

function checkForDomainEmailMatch()     {
                /*      usage:  emailAddress
                                emailAddress name(s)

                        returns:

这似乎工作得很好 - 它适用于gmail。
