Hi, is that not already covered by any SPF checks? Given that you have defined a SP for your domain, SpamAssassin should already be taking care of this. Have you enabled SpamAssassin's SPF checks? If you are not using SA, I believe I have seen a SPF script for TMDA somewhere in the wiki or you could look for a stand-alone SPF checker.
