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
