If you know where all of your own email should originate then it is fairly trivial to catch this, I do it in filter_recipient so I can do some other checks on recipient as well but you could do it in filter_sender just as easily. Just check the relay_IP if the message claims to originate from you or your customers. I also check for authentication as well to allow for customers that are outside my controlled IP space to still be able to use our server (In fact they cannot use it at all unless they auth when outside our network). There are examples that are fairly close to what you want with a minimum of tweaking on the wiki as well as in the man page for mimedefang-filter.
