Authentication, reporting & conformance, or dmarc, is a protocol that uses sender policy framework ( spf) and mail identified by domainkeys ( dkim) to determine the authenticity of an email message. Dmarc records make it easier for internet service providers (isps) to prevent malicious email practices, such as domain spoofing to phish recipients' personal information. Essentially, it allows email senders to specify how to handle emails that have not been authenticated using spf or dkim. Senders can choose to send these emails to the spam folder or block them all together. By doing so, isps can better identify spammers and prevent malicious emails from invading consumer inboxes while minimizing false positives and company mailing list providing better authentication reports for greater market transparency. Your dmarc record is published with your dns records and includes: fps a record cname (dkim) it is important to note that not all receiving servers will perform a dmarc check before accepting a message, but all major isps do and the implementation is growing. What are the benefits of dmarc? There are a few main reasons why you would want to implement dmarc: reputation: publishing a dmarc record protects your brand by preventing unauthenticated parties from sending email from your domain. In some cases, simply publishing a dmarc record can result in a positive reputation boost. Visibility: dmarc reports increase the visibility of your email program by letting you know who is sending email from your domain. Security: dmarc helps the email community establish a consistent policy for handling messages that fail to authenticate. This helps the messaging ecosystem as a whole become more secure and reliable. What does a dmarc record look like? You can see what a dmarc record looks like by typing <dig txt _dmarc.Sendgrid.Net > in your terminal .
