最后一句 说
IP和SPF记录不匹配

hyflexshenwei

spf记录是什么呢？
IP 记录又是什么呢？
我应该在哪里改呢？？？

SPF是跟DNS相关的一项技术，它的内容写在DNS的txt类型的记录里面。mx记录的作用是给寄信者指明某个域名的邮件服务器有哪些。SPF的作用跟mx相反，它向收信者表明，哪些邮件服务器是经过某个域名认可会发送邮件的。

由定义可以看出，SPF的作用主要是反垃圾邮件，主要针对那些发信人伪造域名的垃圾邮件。

例如：当coremail邮件服务器收到自称发件人是spam@gmail.com的邮件，那么到底它是不是真的gmail.com的邮件服务器发过来的呢？那么我们可以查询gmail.com的SPF记录

lz是什么邮件系统？ 用了什么反垃圾产品
你暂时关闭一下自己的反垃圾策略 相关spf检查部分功能

同时让对方检查 为什么dns中的 spf记录和邮件服务器ip地址不匹配

各位大侠：
     辛苦了。我用了的是EXCHANGE服务器。最近用了263的免费的反垃圾邮件系统。出现了这个情况。问题是我不知道SPF问题怎么解决？我刚才联系了263反垃圾邮件客服。不知道是要他们解决还是我的服务器上做什么设置。对方是客户，我门要他们解决是不可能的。只是先查明是什么问题在告知他们是可以的！附退信：

spf问题只能可户自己解决
告诉客户这个问题就好了  
既然他们会做spf应该就知道是什么问题

263的网关我不清楚，不知道他们是不是直接拒绝spf不正确的ip来信

这个问题解决了吗?怎么没有回复了？学习中。。

要反垃圾服务商调整了策略就OK了
