Re: [dmarc-ietf] Proposed text for p=reject and indirect mail flows

No: it should be doing both.

Let’s look at it this way:

Suppose a general-use email provider called “Hooya” promulgated a policy
that said receiving domains should bounce any message from a hooya.com
sender that was fanned out to mailing list recipients.

I think that, worded that way, we would all agree it’s a bad idea.

If we were writing a policy spec of some sort and we were addressing this,
I think we should say BOTH that such a policy is inappropriate in that
would damage mailing list operation AND that receiving domains should not
be accommodating that policy.

Hooya’s use of p=reject would amount to announcing that policy, given how
mailing list software works and has worked for decades.
