I've found the thread and downloaded the code posted by Steve Freegard.
I've also seen Ken A's code snippet to prevent SA caching if particular headers exist.
 From those I think I should be able to write a perl routine to detect the headers I need.

BUT it's not clear to me how these custom functions are used.
Obviously you place them in the /etc/MailScanner/CustumFunctions area, but how are they called, triggered, etc?
How do I stop spam checks from happening by using these functions?
Can you tie the function to the "Spam Checks" setting in the MailScanner.conf file somehow?
I've got the logic, but I haven't got the glue :)

If I get something going, I'll post it back against this thread as quick mini-howto I guess.
