Good eye, good eye! I forgot, as is, this does not cover forwarding.
The only forwarding I have in /etc/aliases doesn't care if it is
sanitized.

So the solution would be to have a .procmailrc in the home directory
of the recipient with a forwarding recipe (or whatever else might work
there), or, in /etc/aliases for forwarding, have a
'/etc/procmailrc.forwarding' file with something like the following
at the bottom of the recipe:

        :0:
        * ^From \/.*
        |$SENDMAIL -oem -odq -oi  -f "$MATCH" forward at address.com

You have to season to taste, YMMV. Maybe someone else has a variation
on this theme that makes it more straight forward, but as is, has worked
great for me so far and is easily extensible.

Thanks,
