Guides DMARC External Destinations verification The aggregate (rua) and failure (ruf) report destinations can be specified within the domain's DMARC policy. And while it is possible to specify a destination on a different organizational domain, the receiving domain must expressly indicate that reports for other domains are welcome. The absence of this record
Tech Why use URIports for your DMARC monitoring? DMARC, SPF, and DKIM have been around for more than eight years now. Every day, more domains adopt this mechanism to increase email deliverability and protect against email spoofing and phishing attacks. The "R" in DMARC stands for Reporting, and it is one of the great features of
