Besides the score points from SpamAssassin, there are some mechanisms
in amavisd to allow it to contribute its own score points to the
end result (sometimes called score_boost, can be positive or negative).

The following mechanisms can currently contribute score points:
- soft black- and whitelisting (controlled by: @score_sender_maps or SQL);
- pen pals (controlled by: $penpals_bonus_score, $penpals_halflife);
- bounce killer ($bounce_killer_score);
and a somewhat differently implemented mechanism but similar in effect:
- @virus_name_to_spam_score_maps

Judging from your reported score (+10, an integer), my first guess is
you have a non-empty @score_sender_maps.
