各位大大您好：
目前有發生一個情況，不曉得是那裡有問題，請各位大大幫忙，
有客戶8/2寄出的信，mail server在8/4號才收到記錄，不過信件一直無法正常收下，在8/5才順利將信件收下


8/4 smtp in log如下：

看看這句

Wed 2009-08-05 21:41:00: * relays.ordb.org - failed to pass

也就是黑名單檢查不通過，客戶的郵件主機名列黑名單中。

chiawei29

那...需在那裡設排除的名單呢？

March大：
我在SMTP IN log裡發現，不管是否成功收到信件，
都會有這行 relays.ordb.org - failed to pass
這需要關掉嗎?

MarchFun

關於 DNS-BL，可以參考：
http://www.suma.tw/forum/tag-DNS-BL.html
可以不用關，找到 DNS-BL 的設定，在 white list（白名單）中加入客戶的 IP 即可避開。

chiawei29

March大，我爬過文了，不過在我的mdaemon server沒看到dns-bl設定的地方，
我是7.2.3版的

MarchFun

7 版的時候可能不叫這個名稱，我也忘了。找找相近的功能。
