Spamassassin not working

I have Virtualmin GPL, it appears spamassassin is not being used when recieveing emails. I have tried using the spamassassin test string and it is never detected as spam. I have checked and the filters from procmail are working, it appears as if Spamassasin is never involved. I have double checked it is enabled, the service is running and the website has spam assassin enabled. I have also checked the procmail filters which virtualmin creates to ha nd spamand viruses to the various services and that seems to be generating fine.

Anything I can do? I am not sure if the virus checking is working either, probably not.
