[Exim] Local users spam filtering

Hi all, hope you are all getting ready for a nice festive season.

Just thinking, today we upgraded all our servers to exim 4.3 and
spamassassin 2.61. We still get some of our local users email caught in
our spamtrap because they use OE with html and do silly things like odd
fonts etc.

I was thinking of either not spam filtering email from our own ip range,
or adding a spamassassin rule to give a big neg score for email from our
own ip range. Is anybody doing similar and if so how are you doing it?

I don't want to add neg scores for our own domain in the from as a lot
of spam seems to forge our domain in the from line.
