最近老是拒收客户邮件

mayborn

启用了rbl：zen.spamhaus.org
其他都是默认设置，这两天很多客户，包括在trust domain上的发邮件过来都被拒
不晓得什么原因啊

应该修改策略的哪些部分呢，信任域现在不能完全解决
每天拒收的垃圾邮件在50%左右。

换个DNS试试
zen.spamhaus.org - failed没起作用

嗯，用的电信的dns啊
不敢随便换
我取消掉rbl算了
客户为什么会退信呢？

因为DNS－BL挡了，默认设置被DNS黑名单挡会返回未知用户错误信息。

但是我去spamhaus查询他们的ip不在任何黑名单之列
只好先去掉rbl看看效果了

wxhsh

可能你的DNS SERVER被劫持了，那只能去掉RBL或更换DNS SERVER

嗯，我朝DNS劫持太普遍了
但是又不敢随便换
大家有用过opendns的么

wxhsh

我的经验是找全国的DNS SERVER，然后从最接近物理位置的地方测试，找速度快并未被劫持的，累是蛮累，但也是一劳永逸（相对）的事。
