Scott,
[using DKIM and (lax) DMARC myself, usually just lurking]

This will *still* break anything using DMARC, because neither DKIM nor
SPF is valid. Anything *not* using DMARC is better off, though.
Ideally the email modifications are disabled entirely. The emails can be
reliably detected using the List-Id header and filtered based on it.
