I don't know about that. I run a lookup and I get a valid MX record:
HEADER:
opcode = QUERY, id = 43594, rcode = NOERROR
header flags: reply, want recursion, recursion avail.
questions = 1, answers = 1, auth. records = 3, additional = 3
QUESTIONS:
comcastbusiness.com., type = XX, class = 1
ANSWERS:
-> comcastbusiness.com.
type = MX, class = 1, ttl = 3180, dlen = 18
preference 100, mail exchanger = 208.39.158.132.
