Where you send selected messages to Spamassassin, try this.

Firstly we define $doSA, and then undefine it if the message is
considered local in some way, such as smtp auth, from localhost,
or from a couple of secure campus servers we trust.   Then:

    if ($Features{"SpamAssassin"} && defined($doSA)) {
        if (-s "./INPUTMSG" < 150*1024) {
		# Send it to SA as per usual and do the
		# usual insertion of headers.
		# We put the score in ALL mail SA sees, even 0.
        } else {
            action_change_header("X-No-Spam-Score", "Too long");
        }
    } else {
        action_change_header("X-No-Spam-Score", "Local");
    }

This way we have one of two X-No-Spam-Score headers in there
if we deliberately did not send it to SA.
