DMARC policy rejects messages only when they failed both SPF and DKIM checks. It seems problem is that mailing lists like to mangle message content.

- phicoh 10y agoThat's not a problem. Mailing lists have been doing that since long before DMARC. Having the mailing list name in the Subject is very handy. Footers are also more convenient that having to look in headers.
- Nazzareno 10y agoNot exactly, the DMARC policy is very flexible. Each server, after a period of monitoring when he receives a detailed report of what would happen if a policy is enforced, can define his own policies.
