    Stopping email spoofing with a DMARC record

    As the use of email spoofing continues to rise, more organizations are turning to DMARC protocols and publishing DMARC records to help combat this dangerous threat.

    Email spoofing is a form of cybercrime where attackers send an email that appears to come from your organization. Spoofed emails may target your employees, customers, partners or suppliers. By impersonating a trusted source, attackers try to get the email recipient to reveal login credentials, share sensitive data, or transfer funds to a fraudulent account.

    Email spoofing takes advantage of the fact that it's very easy to make an email appear to come from any address. DMARC, or Domain-based Message Authentication, Reporting & Conformance, is an email validation system that can help receiving organizations stop the delivery of spoofed emails and help sending organizations discover scammers who are using their domain without authorization.

    When using the DMARC, an organization publishes a DMARC record that lets a receiving email server know what to do with messages that fail a DMARC test.

    Though DMARC is a powerful tool for stopping email spoofing, it's also a challenge to deploy and manage. Without the right tools, it can be costly and time-consuming to establish DMARC policy enable email servers to perform a DMARC check. To simplify DMARC implementation, Mimecast provides an industry-leading solution in Mimecast DMARC Analyzer.

    FAQs: What is a DMARC record?

    What is DMARC?

    DMARC is the Domain-based Message Authentication, Reporting & Conformance protocol, a system for validating the authenticity of emails. DMARC builds on two widely used email authentication protocols – Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) – to help a receiving mail server judge whether an inbound message is legitimate.

    What is a DMARC record?

    DMARC record is a DNS text record that is published in a domain's DNS database. A DMARC record lets ISPs know if a domain is set up to use DMARC and lets receiving email servers know what the organization's DMARC policy is concerning messages that fail SPF or DKIM authentication. A DMARC record may specify that messages which fail to authenticate can be delivered in the inbox, sent to the spam folder or needs to be blocked.

    What is a DMARC record check?

    A valid DMARC record is required when deploying DMARC. A DMARC record check is a diagnostic tool that parses a DMARC record and determines whether it is valid. Mimecast offers a free DMARC record check along with free SPF and DKIM checks.
