一段时间以前，我注意到，我的域名的电子邮件不是马上提供的谷歌，我从谷歌服务器得到一个SMTP错误消息。 我不记得那条消息的确切措辞，但是使用googlesearch，build议我需要设置SPF和DKIPlogging。 我做了哪些 它解决了谷歌不接受电子邮件的问题。 但是现在，几个星期后，它又打开了一封回复电子邮件的大门。 以下是我将域名replace为mydomain.com的一个示例

我现在每天得到数以百计的这些。 这是否有可能是因为我configuration错误的SPF？
这是我的spflogging：
v=spf1 a mx include:_spf.google.com ~all
我的大部分设置（最近刚刚添加的SPF和DKIP除外）在此描述： 邮箱中新文件的Postfix / Dovecot权限 ）
我相信你遇到的是Backscatter电子邮件，请查看维基百科的详细描述。 简而言之，如果有人使用伪造的地址发送垃圾邮件（在这种情况下是您的），并且退回邮件发送回您的地址，则会发生反向散射。 许多邮件服务器通过使用称为退回地址标签validation（BATV）的技术来标记每个发出的电子邮件来解决这个问题，并且当邮件服务器得到弹回电子邮件时，可以判断它是否是之前发送的电子邮件的反弹。 如果不是，则根据您的configuration方式拒绝或将其标记为垃圾邮件。
查看原始邮件的标题，返回path设置为您的地址，这意味着如果垃圾邮件发送者的电子邮件未能送达，则退回将被发送到您的地址。
Return-Path: <[email protected]>
原始IP似乎是104.220.1.229，在DNSBL上快速search显示这个IP被许多人列为垃圾邮件的来源。
Received-SPF: softfail (google.com: domain of transitioning [email protected] does not designate 104.220.1.229 as permitted sender) client-ip=104.220.1.229;
解决scheme – 您可能需要设置BATV以防止将来出现此类分散的电子邮件。
除此之外，请检查您的SPF条目，您是否说过不使用Gmail作为中转，那么为什么要把Gmail的SPFlogging？ SPFlogging旨在添加作为您的域的合法电子邮件源的发件人主机列表。 如果您不使用Gmail进行中继，请将其从SPFlogging中删除。 只能添加您的SPFlogging中的发送主机的IP地址。
