This would work with maildrop:

This doesn't work, because the administrator's mailbox isn't
accessible, but you can forward the mail to the admin (I'd probably
use someuser+spam or something and add a ~/.forward+spam with separate
filtering instructions).

I understand Sam's position. Getting this convenience feature of
procmail's right isn't easy, and if something is wrong, you're giving
r00t privileges to any local user.

You can however use Postfix's content filter to divert mail, you'll need
to write a small script though. Examples in the Postfix documentation.
