try helo filtering - a lot of yahoo is forged into the helo

then use cbl.abuseat.org (or sbl-xbl.spamhaus.org) to filter email

you wont get to see yahoo email originating only from their MXs - they
have a rather more well developed network than that

but 99% of the yahoo spam you get will not have originated from yahoo's
systems or users

callouts are generally something that deserve to die a miserable death,
and they wont work with yahoo anyway (it runs qmail so the principle
behind callouts fails)

cbl and helo filtering should help you
