How do you stop incoming mail from using that address though and bypassing
your anti-whatever implementation?

On that note, it's always a good idea to have your internal SMTP server's
address listed as an MX for your domain (put it to the highest), since some
sites will look at the received headers to determine if the mail originated
from a valid MX for that domain as an anti-spam tactic.  It's not that
common, but it doesn't hurt to do it.
