Sure. We have many parts of the business (we are 40.000+ employees) need some 3rd party system to send e-mail. Some of these companies, even best of breed in their specific area, does not know anything about e-mail, RFC etc. So we tell the business unit to use a subdomain and a reply-to on our primary domain. Then we try to get the supplier to help with either SPF (if we are lucky, or tries hard enough) or DKIM (impossible).
We are not alone here. We have all sorts of systems like newsletters (they do DKIM etc), HR system, time registration system, other misc systems. Maybe it is 10 subdomains only, and maybe we should just create DMARC record for all of them with p=none - and not depend on sp=none. -----Oprindelig meddelelse----- Fra: dmarc-discuss [mailto:[email protected]] På vegne af Sim via dmarc-discuss Sendt: 12. december 2016 08:34 Til: [email protected] Emne: Re: [dmarc-discuss] gmail's DMARC check doesn't respect subdomain policy Am 12.12.2016 um 07:47 schrieb Roland Turner via dmarc-discuss: > ...
