Perhaps it is causing fps because of something else in your mail path. For
instance, if you have a virus scanner that inserts oddly-formatted Received:
headers this sort of rule will often end up triggering, since you have
managed to reproduce a typical spammer indication, presumably
unintentionally.
The fact that this rule is triggering may indicate there is something in
your setup that will cause other rules to trigger at receiving sites,
resulting in most of your mail being marked as spam, whether it is or not.
The correct solution is usually to see what is wrong with the setup that is
making your mail look like spam.
I suggest you post an example mail WITH HEADERS that shows this hit, and
someone can probably point out why it is happening. Without an example all
we can do is suggest lowering the score, since we don't know what the real
problem is.
