OK, that's a help.

You could do something like this (pseudocode)

if ($Sender eq '<>' and $RelayAddr eq 'ip.of.exchange.box') {
    open(IN, "<INPUTMSG");
    while(<IN>) {
       # Check for a spam score greater than threshold by parsing lines of
       # the mail body
       if ($score > $threshold) {
           action_discard();
       }
    }
    close(IN);
}
