If you're going to do something that will break the DKIM signature as a matter of course, You should remove the DKIM signature, and maybe re-sign it with your own.
You shouldn't break the signature and then forward what was once goodmail with a now busted signature.

Why? The DKIM spec is super duper 100% clear that an invalid signature is the same as no signature. Any system that scores against broken signatures is badly broken. It's not surprising that there are badly broken systems, but please, let's encourage people to fix what's broken rather than telling them to apply band-aids.
