I meant you could use your own script.  Something like (untested):

---
import sys

from spambayes.storage import open_storage
from spambayes.tokenizer import tokenize

# Open existing token database.
db = open_storage("db.name", "pickle", "r") # or "dbm", or "zodb", etc

# Read the message from stdin, and tokenize and classify it.
message_text = sys.stdin.read()
all_tokens = tokenize(message_text)
classification, clues = db.spamprob(all_tokens, True)

# Separate out the clues into ham & spam.
ham_clues = [clue for (clue, prob) in clues if prob <= 0.5]
spam_clues = [clue for (clue, prob) in clues if prob > 0.5]

# Print out the results to stdout.
print len(ham_clues)
print len(spam_clues)
