And then configure yum to gpgcheck :)

rpm signature checking just doesn't work like this.

NOT OK will only occur if the file is corrupted - if it is an intact rpm
but unsigned it still has a header digest and a header+payload digest to
verify it's untampered with. Thus rpm -K tells you this is the rpm
built and intact and the payload and headers are consistent with the
digests. Obviously it can't reveal anything about the trustability of
the package as it could be anything built and packaged:
cp yum-2.0.7-3vmw.noarch.rpm broken.rpm
echo 'A' >> broken.rpm
rpm -Kv broken.rpm
