Well, if the messages has almost only header and that is not
understood ...

Here is what you could do: Take you current database to
decide if something is spam or not (not using header
tagging). Use those new mails (now with header tagging) to
build a new database. For a while you'll have to correct
errors in both databases, but after not too long you can
just switch the database.
