Re: [NTG-context] This mailing list is not DKIM (DMARC) compatible

In addition: Lists should keep the From address, the Subject, and the Message totally unchanged. They should add a Sender header to indicate their relay role, and set at least the List-Id and List-Unsubscribe headers for mailbox rules and subscription management.

The footer that is added to each message in this list is not DKIM (and thus DMARC) compatible. DKIM requires the ability to create a signature on a set of headers and the body. By changing the body, the DKIM signature fails and the resulting messages sent by the mail list may in the future be blocked by more and more mail servers.
