Dont have an office or server in Brazil? Open those RFEs folks!)? As a less than ideal workaround for this problem, Proofpoint customers can create a Policy Route that matches on message From headers that end with their domains, and then create a DMARC policy in Proofpoint that applies to that route, and configure the policy to copy any messages that fail DMARC to a separate quarantine folder for later review. Sender Policy Framework (SPF) is an email validation protocol that allows an organization to specify who can send email from their domains. By design, SPF only authenticates the Envelope Senderaddress, leaving the From Header address unchecked. Domain-based Message Authentication, Reporting, and Conformance (DMARC) is an essential tool for solving both of these problems. Care should be taken to configure explicit subdomain DMARC records where you don't want the subdomains to inherit the top-level domain's DMARC record. DKIM lets you add a digital signature to email messages in the message header. For example, a message might fail DMARC if it's sent to a mailing list that then relays the message to all list participants. ARC preserves the email authentication results from all participating intermediaries, or hops, when an email is routed from the originating server to the recipient mailbox. Microsoft 365 currently utilizes ARC to verify authentication results when Microsoft is the ARC Sealer, but plan to add support for third-party ARC sealers in the future. Also, you can add a wildcard-type policy for DMARC when subdomains shouldn't be sending email, by adding the sp=reject value. All rights reserved.
