BAYES_00 and BAYES_99 hit on other ham/spam without any problem. Only
then the result will mention autolearn=disabled instead of
autolearn=unavailable. I don't follow why it would be unavailable for
non-shortcirtcuited emails, but disabled for shortcircuited emails.
It has to have accessed the Bayes dB in order to score with BAYES_00/50/99.
Best time me to run sa-learn --force-expire is this evening, as only US
time zones are using the server. The main users are in Oceania and the EU.
Cheers,
