Hi
It’s been mentioned that the Sender’s DMARC Policy help receivers (recipient domain) take a decision whether or not to quarantine/reject an email sent by them.
Am a bit confused, I thought it is the receiver’s DMARC settings configured on the receiver’s domain DNS DMARC TXT record, which enforces what to do with an email that is received from the sender that does not match SPF and DKIM records of the sender.
I believe the sender’s DMARC policy has nothing to do with recommendations for an email that’s sent by them and it’s totally up to the receiver to take a decision by comparing the SPF & DKIM records received in the email and what does the receiver end DMMARC policy enforce.
However I understand that DKIM and SPF are public DNS records that are hosted by the respective domain providers, not sure if the receiving domain also checks the DMARC record of the sender and how the decision is taken based on senders DMARC policy for receiving domains to accept or reject an email. Can receiving domains access the dmarc policy of the sender?
Are there two DMARC policies configured per domain, one where the receiver domain can check what needs to be done when an email fails from a particular sender and where is this policy configured or the receiving domain goes with its configured DMARC settings to accept and reject any email from any sender?
