| As far it it goes, yes. How would it learn?
I have some ideas about how you could hook this into Mailman to do
community/membership assisted learning. Understanding that people
will be highly motivated to inform you about spam but not about good
messages, you essentially queue a copy of a random sampling of
messages for a few days. Members can let the list admin know about
leaked spam (via a url or -spam address, or whatever) and after the
list admin verifies it, this trains the system on that spam. If no
feedback on a message happens after a few days, you train the system
on that known good message.
You need list admin verification to avoid attack vectors (I get mad at
Guido so I -- a normal user -- label all his messages as spam).

But there might be some interesting, integrated ways around that. Say
for example, you take a Python-enabled mail server, parse the message
into its decoded form early (but not before low level SMTP-based
rejections) and then pass that parsed and decoded message object tree
around to all the other subsystems that are interested, e.g. the Bayes
filter, and Mailman. You can at least amortize the cost of parsing
and decoding once for the rest of the lifetime of that message on your
system.
I think we have all the pieces in place to play with this approach on
python.org.
