Proofpoint will never bounce or reject mail based on a domain’s DMARC policy Depending on the DMARC policy of the From Header domain, Proofpoint will take one of two actions. If the DMARC policy is p=reject or p=quarantine and the email fails DMARC authentication, then the email is quarantined and categorized as Fraud.
Proofpoint has SPF and DMARC published, I would hazard a guess they have DKIM, which means if you are using their services, you wont need to do anything if they are your primary MX record for your domain. If you are pumping mail out to them after it hits your primary MX (Office365, I assume), then you should implement all three.
– Record, Verification & More | Proofpoint US DMARC is an open email authentication protocol that provides domain-level protection of the email channel. DMARC authentication detects and prevents email spoofing techniques used in phishing, business email compromise (BEC) and other email-based attacks.
An accurate DMARC record is an important step in securing your email traffic. Use this tool to check your domain’s record and validate that it is up to date with your current policy.
