SpamCheck report

It doesn't matter what you call your Custom Function, just call it
whatever you put in the MailScanner.conf line, so
Spam Checks = &MyCustFunc
is just fine, your Custom Function is called MyCustFunc.
You don't normally need any parameters to the Custom Function.
The result of the Function is the value you want to supply to that
configuration option, with one exception:
Instead of returning no or yes, you should return 0 or 1.
Other than that you return the value you want that config option to have.
Just like a ruleset applies tests to the from+to addresses of the
message to work out the value, a Custom Function runs a bit of your code
to work out the value.
