This is one of the techniques that the SpamDunk ruleset uses.
The problem is that mailing lists meet this criteria, and I

This changes frequently.
  Actually, every recipe of SpamDunk assumes that an email is
not from a list (I'm the author, so I should know<g>).  The
problem I have with mailing lists is that there don't seem to
be rules that apply to every list.  The Procmail list
headers scream "list"...

Resent-Message-ID: <"HVBzI.A.YSH.HJAp1"@campino>
Resent-From: procmail(_at_)informatik(_dot_)rwth-aachen(_dot_)de
X-Mailing-List: <procmail(_at_)informatik(_dot_)rwth-aachen(_dot_)de>
archive/latest/18149
X-Loop: procmail(_at_)informatik(_dot_)rwth-aachen(_dot_)de
Precedence: list
Resent-Sender: procmail-request(_at_)informatik(_dot_)rwth-aachen(_dot_)de

...whereas other lists simply have multiple "Received:"
headers from three different domains, just like a relay-spam.
On the other hand, if there was a set of rules that every
list followed, spammers would use them too.  There was one
outfit that sent spam "From: majordomo(_at_)hk(_dot_)super(_dot_)net".
  If your ISP supports plussed addresses, you might try
subscribing to lists with a plussed address, and have
procmail divert all email with plussed addresses past your
regular filters.
