The known antispam technique is not having unresolvable MXs, it is
having _unreachable_ MXs. Really different, i think
From http://wiki.apache.org/spamassassin/OtherTricks
"The fake records can either be undefined or can point to dead IP
addresses or to real IP addresses with port 25 closed. <b>On the lowest
numbered MX be sure it's pointed to a closed port</b> because if you
just use a temporary error then Qmail, which is not RFC compatible, will
never move up to the next MX record."
For undefined, I understand unresolvable (that is, the host in the MX
doesn't point to any IP address).
Anyway, there are legitimate senders that are pointing to unresolvable
MX records, and they don't like the fact that our mail servers reject
thier mail saying that it's unresolvable (when it is), so I think that
was a must-fix for us :S
