Hi Hua,

I think I am totally confused. The lists I subscribed to seem have no MX
records? For example,
$ dig lists.openstack.org mx
# got nothing
$ dig lists.dns-oarc.net mx
# got a CNAME
If no MX provided, how will the messages be routed?
"The lookup first attempts to locate an MX record associated with the
name. If a CNAME record is found, the resulting name is processed as
if it were the initial name."
"If an empty list of MXs is returned, the address is treated as if it
was associated with an implicit MX RR, with a preference of 0,
pointing to that host."

Thanks.
