- ham: the message was learned as ham (non-spam)
- spam: the message was learned as spam
- no: the message was not learned
In SpamAssassin 3.0, the result was enhanced to have six states:
- ham: the message was learned as ham (non-spam)
- spam: the message was learned as spam
- no: explicitly that the specific message didn't achieve the proper threshold values and requirements to be learned
- disabled: means that the configuration specifies
bayes_auto_learn 0oruse_bayes 0and so no autolearning is attempted - failed: means that autolearning was attempted, but couldn't complete. This happens if SpamAssassin can't gain a lock on the Bayes database files, etc.
- unavailable: catch-all for anything autolearning not completed for any reason not covered above.
Question: Which of the six states means "Autolearn not performed: message already learned"?
Answer: For some reason, it seems to be the unavailable state.

- It could be the message was already learned.
