You may want to have a look at MailWasher (<http://www.mailwasher.net/>).
It can probably filter out the undesired mail by means of its public and
your private blacklists. If not, you can create extra Filters. Filters
can filter on things being (not) equal to some expression, so if you
make a rule like "From: not equal to <something>", then that essentially
means "From: empty". FWIW, I use Mailwasher and am quite pleased with it.
A note of caution: MailWasher can "bounce" back undesired mail. Do *not*
use that facility, because most likely the bounced message will not be
sent the the original sender, but to an innocent bystander. I.e. do not
(try) to 'solve' your spam problem by sending it to someone else.
