Perforce has facilities designed specifically to support this kind of
thing - counters and the "review" command. You can find a brief
description plus a link to the perforce-standard review daemon here:
It's designed to send email to perforce user.
Actually, something similar ought to be running on the repository
already. If so, and you're not using it, you can 'cheat' by setting up
the mail list you want and pointing your p4 user Email field at that,
along with the appropriate Reviews setting for yourself.
