邮件服务器换了IP地址后有些域名的邮件无法发送接收了。

paleskyunix

由于邮件服务器换了托管机房，所以更改了IP地址。域名解析什么的都改过来了，WEB服务都正常，qmail服务也基本都正常。但是有部分原来可以往来的公司现在却不能和我们彼此通邮件了。请教一下这可能是什么问题啊？

一般而言，是你的新IP段被一些地方BLOCK了（黑名单问题）

我问了对方，他们说没有把我们列在黑名单理啊！如果是黑名单的问题，那要怎么样解决呢？

思一克

不是对方列入的！
而是BLACK LIST机构。对方只是使用了机构的LIST而已（使用者自己不知道具体哪个被列入了）。

你可以看MAILLOG，会知道是否是这个原因。
