SPAM score test result (not problem, asking for help :) )

Hallo, i try some "Spam socre test" - it seems to be OK 10/10 for not SPAM.
But there is one warning in section "Spam Assasins likes you"

DKIM_SIGNED Message has a DKIM or DK signature, not necessarily valid
This negative score will become positive if the signature is validated. See immediately below.


How can I fix it?

Many thanks for help
