My mail system has a number of users, and I prefer to let the recipient
decide what is spam.
The question was really about the empty spams that are showing up in
the last month or so, and what they are intended for. Weather it was a
prelude to an MTA exploiting worm strike, or just spammers assessing
the value of their spam lists before using them to deliver their
spamloads.
My content filtering mostly works. It catches over 99% of spam and I
have only had 1 false positive, and I think I will stick with it.
Some list servers such as yahoogroups (May it rot in pieces) have the
annoying behavior of deactivating your subscription on hard bounces
from MTAs so whenever a list I am subscribed to with lax attachment
policies gets a worm, and I hard bounce it with mime-header-checks, I
get deactivated. So this is just one example of hard bouncing spam not
being a great system wide policy right now (Unless you don't like your
users :P).
