I have to ask: standard *how*?
It looks to me like you're using MailScanner or AMaViS (the existence of
the "spam-scanned" protocol lines give that away); both of these are
fairly old-fashioned nowadays, given that neither does realtime
rejection.
To answer your question: whatever you're using, change the headers you
add so they're "personal" to your operation (say "X-Dobson-Scanned")
instead of the "standard" ones.
Additionally, look up the "headers_remove" option for your routers:
