First: you can't do that using procmail alone. A perl, python, ruby or
whatever script will be needed. Simply pipe all incoming mail to your
script via procmail.
That said, I doubt such a script which *reliably* detects top-postings
can be done. As a starting point for your language problem: simply
check if the first line in the mail body ends with a colon (":").
