Most likely these header fields were inserted by some remote mailer running SpamAssassin, over which you may not have any control. Amavisd would not see or check X-Spam-* header fields added by itself (or from SpamAssassin invoked from it).

This is not a default behaviour, normally such errors in header are only flagged/logged as a warning, but a message is delivered nevertheless. There is no particularly good reason to block such messages, but you can if you want to.
