One of the most recent advances in email technology, Domain-based Message Authentication, Reporting, and Conformance (DMARC), is also one of the most misunderstood. It plays a role in authenticating the emails you receive, and ensuring that they are not blocked from your inbox.
DMARC ensures that the email you receive or send is legitimate, and authenticates it well against established SPF and DKIM standards. If an email appears to originate from domains that are known to have fraudulent track records, it is blocked.
The two main features of DMARC are reporting and domain alignment. The latter prevents spoofing of the ‘header from’ address by matching the ‘header from’ domain name to the ‘envelope from’ domain name.
DMARC is perhaps the first and only widely used technology that relies on the ‘header from’ address to authenticate emails. This helps protect both customers and brands, and discourages cybercriminals who are less likely to target organizations with DMARC records. DMARC records can be created in as little as 15 minutes if you have the right resources available.
