Smotrim RFC 1035:
3.3.9. MX RDATA format
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
PREFERENCE
EXCHANGE
where:
PREFERENCE
A 16 bit integer which specifies the preference given to this RR among others at the same owner. Lower values are preferred.
EXCHANGE
A domain-name which specifies a host willing to act as a mail exchange for the owner name.
MX records cause type A additional section processing for the host specified by EXCHANGE. The use of MX RRs is explained in detail in [RFC-974].
