Yes, a mis-configuration in your case (see my other mail message).

In particular, snowshoe spamming...

(I blacklist the corresponding IP blocks completely, and check the logs
from time to time. But this is always 100% spam.)

But some spammers also use compromised machines, which normally never
send mail directly, so that some of them are not configured with a
valid reverse. That's why rejecting such suspicious mail may be
useful (I would rather do that combined with countries, e.g. China,
if possible).
