Exactly what I always wondered. What in the heck is the point of
pointing an MX record to something invalid, when simply removing
MX and A records does the job much more wonderfully, and presents
a better error to the end user (invalid domain instead of connection
errors).
Spammers usually try direct delivery to A records anyway, so having
bogus MX records to fend away attempts to the A record is pointless.
