DNS config problem

Thu Oct 3 22:49:39 UTC 2002

I need to verify whether the following DNS config is correct.
MX v8' A record is not specified.
Should the next MX record be picked up?

* Configuration of DNS
$TTL    30
@       IN      SOA     bltest.example.com. postmaster.bltest.example.com. (
        2002090404 1800 900 1209600 43200 )
       IN      NS      bltest.example.com.
       IN      A       16.161.29.51
       IN      MX      2 v8
       IN      MX      200 v4
v4      IN      A       16.161.29.50
