If you'd have provided the actual MX domain I'd be typing the answer to
your question instead of scolding you for obfuscating information that
is necessary for us to help you.
As a general rule, unless lives or millions of $currency is at stake,
don't obfuscate domains and IP addresses. It simply eats more of your
time, and ours, and delays a solution.
