标题: 客户发不进来邮件，提示550
换到9.65
启用了rbl-
用了才一天，客户邮件就发不进来了
是试着用yeah.net，gmail，hotmail发给自己
yeah和hotmail都退信
内容为550 user know
这种问题应该从何着手解决
谢谢！

现在把rbl-去掉了
只留了默认的zen.spamhaus.org
退信太多了
只能喊救命了

你加了几个DNS-BL？？

启用RBL前先确认下自己的DNS没有被劫持，偶也是更换了全国的N个DNS SERVER才找到一个最快最稳定并没被劫持的。

两个啊
默认的和rblless
我们已经做了反解
现在把rblless去掉，yeah发过来接受正常了
太崩溃了
一夜都没邮件

很有可能你的DNS被劫持了。也算中国特色

多谢真知灼见，目前把rbl-去掉了
只留了个zen.spamhaus.org
我这是合肥电信dns，劫持经常出现
现在只保留国外的rbl是不是算暂时解决问题

如果存在劫持，保留任何都没用，因为MD的DNS-BL是不带校验的。

那我在MDaemon的备用DNS里填上个可用的
就可以继续使用rbl么
冒着危险保留一下spamhaus
静观其变
多谢大大指点！

只有在主DNS无效的情况下才会去找辅DNS，所以应该没用。你可以看SMTP-IN日志，DNS－BL应该全是“失败”。

吐血的是加入信任域了还是被退
只好去掉dns black list
呵呵，该找个详细的技术文档好好充电了
