Had you read the whole thread from the beginning, you would know that Lindsay is not talking about mailing list mail here.
I've ported much of the MM 2 DMARC mitigation code to an email processor for the Courier MTA. The principles I've used could probably be applied to many MTAs. If anyone is interested, I'll be happy to post my code (dmarc_shield.py) to this list as an attachment, and if anyone has the time and inclination to critique it, or point out potential bugs or problems I'd be happy to receive them.
Many thanks to Mark for taking the time to go over the salient points in the Mailman code in email.
