I have found this list address has no MX record, lists.ceph.com
you can find their subscribe info at,


So some email systems can not deliver messages to it, such as Aliyun's 
which returns,

(8)lists.ceph.com resolving by dns failed

I know the deliver agent should try A record if there is no MX exists.
But any way lacks MX for a public email domain is not good practical.

Is it? :p
