I know the guy who wrote the RFC, and I'm reasonably sure he'd forgive us under the circumstances. There is, after all, plenty of mail from addresses like donotre...@bigbank.com already, and this does the same thing with slightly different and syntax. Note that putting the list's address in From: is also an RFC violation since the list isn't the author by any normal understanding of the term. >Message wrapping is the safest but equally unsatisfying.

The good solution is for the members of the DMARC group to set up and use a shared DMARC-bypass whitelist for mailing lists and other legitimate mail sources that don't match DMARC's narrow security model. I'm working on it, but in the meantime, .INVALID has the advantage of reminding people where the source of the problem lies.
