Unfortunately it takes a lot of effort to create *good* spamtraps. It's just too much trouble for a normal admin, I leave it to those who have time on their hands. You can do the simple grep for "mistyped" non-existant addresses from logs etc, but it's just silly botnet crud that doesn't represent the "real" spam coming to real users (that leak their addresses in all sort of ways). I don't see any point Bayes-learning simple-to-block botnet mails either, since it's completely separate thing from the sneakier 419 and phish stuff..
