Looks quite good  :)

I'm interested if things like source code might trigger some of these
unnecessarily?  Also the amount of processing time might be worrisome?

Definitely gives me some interesting ideas in other areas.  In particular,
the unusual char combinations seem quite useful (maybe it's high time to
find a statistical analysis on an english dictionary).  :)  Interestingly
enough I don't really get any ascii art spams here but a lot of your
techniques look promising.  I guess every site has their own most common
"types" of ham and spam so the ability to customize is really important.
