[exim] using Bogofilter with exim acl

Hello

I have a bunch of rules in my acl that filter out most of the spam, but
to improve it further i need a bayesian filter, i'm trying to use
bogfilter for this. All guides in the net is using bogo as a
router/transport pipe, however i would like to use the spamscoring from
bogofilter in a acl to be able to freeze/reject depending on score from
bogo and other acls. is that possible?, i have tryied to use the run{
feature, but can't figure out how to pass mail to bogo with that :(
