Mimecast DMARC Analyzer is a user-friendly and expert guide to help organizations implement DMARC test procedures and reject policies.
Cyber criminals today are highly successful at using domain spoofing to impersonate a trusted email sender. In domain spoofing, attackers trick email recipients into revealing credentials, sharing sensitive information or transferring money by making the email appear as if it comes from a trusted source. Domain spoofing is commonly used in phishing campaigns and business email compromise attacks, both of which have seen rapid growth in recent years.
Fortunately, brands can combat this type of attack with a DMARC test. DMARC – or Domain-based Message Authentication, Reporting & Conformance – is an email validation protocol that helps to block delivery of unauthenticated email. DMARC builds on existing authentication techniques and enables receivers to distinguish between legitimate and fraudulent senders, specifying what to do with email that doesn't pass authentication.
While DMARC offers a powerful line of defense for preventing domain spoofing, it can be difficult and costly to implement. That's why more organizations today are turning to Mimecast DMARC Analyzer to help accelerate and simplify the task of deploying DMARC.

DMARC is an email authentication protocol that helps domain owners to protect against unauthorized use and email spoofing. DMARC – or Domain-based Message Authentication, Reporting & Conformance – uses the DomainKeys Identified Mail (DKIM) and the Sender Policy Framework (SPF) to validate incoming mail, allowing receiving mail servers to determine whether messages are legitimate and to know how to handle messages that aren't.
When an email server receives an incoming message, it can perform a DMARC test to determine whether the message passes SPF and/or DKIM authentication by evaluating whether the message aligns with what is known about the sender. If a message fails a DMARC test, receiving mail servers can check the sender's DMARC policy to see whether the message should be delivered to the inbox, spam folder or should be blocked.
To publish a DMARC policy, organizations need a valid DMARC record. A DMARC record check is a service that inspects the DMARC record to determine whether it's valid, parsing the record and displaying results. Mimecast provides a free DMARC record check tool along with tools for an SPF or a DKIM record check.
