Procmail hacks are fun, though :-) I've never really played around
with .forward files, but you could probably do what you want using
procmail.  In my sendmail experience (which is incredibly limited), if
you put

	    |/usr/bin/procmail

in your .forward, sendmail will hand messages over to procmail.  Then
in your .procmailrc something like:

LOGFILE=$HOME/procmail-log

:0c
saved-messages

:0
| /path/to/your/script.pl

That'll keep a copy of messages in a saved-messages folder so you can
see what messages are coming in (handy for debugging) and also log a
summary of the headers of each message and any errors from your script
in procmail-log.  Procmail can also do things like only passing
messages with special subject lines, addresses, or whatever to your
script, which may or may not be useful to you.
