Re: [dmarc-ietf] DMARC-Compliant Mailing Lists

[Douglas Foster <[e-mail]>]

I would be pleased to see a document which explains why lists MUST or
SHOULD alter content.    After more than 2 years following this discussion,
no reason for this practice has ever been documented.

Content changes would be easier to justify if subscribers granted
authorization to modify as part of the subscription process.   But there
was not informed consent when I joined this list, so I doubt that informed
consent occurs on other lists either.

What if, after reviewing the SHOULD list, an organization says "That's
interesting but unconvincing.   Please send messages to our domain without
alteration?"   Are lists equipped to give participants what they want, or
not?
