I can't explain why spamassassin would report an invalid signature, but I
can tell you that (a) "insecure key" means you enabled DNSSEC support and
it reported that the key record was not protected by DNSSEC, and (b) "not
authenticated" means the incoming SMTP connection did not authenticate to
your SMTP server using SMTP AUTH. The DKIM-specific parts look fine.
