mail.jingmei.com is delegated to lp.jingmei.com. lp.jingmei.com
doesn't serve mail.jingmei.com for AAAA queries. Note the
SOA record is wrong here.
lp.jingmei.com says there are no NS, SOA or just about any other
records for mail.jingmei.com. The AAAA queries appear to be
going through to another box which is configured to serve
jingmei.com not mail.jingmei.com. I base this conclusion on
the fact that there are different types of negative responses
based on the query type and the flags differ. Note that the
authorative answer for the A query is not right either. RD is
not returned in the answer.
