What is a DMARC Record? How to Create DMARC Records and Improve Email Deliverability

A properly configured email authentication system is necessary for getting the best email deliverability rates and maximizing your email ROI. However, SPF and DKIM authentication may not be enough to protect your domain and IP address from spoofing, while still ensuring that all your emails hit the inbox.

Here’s why.

The Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) authentication protocols were developed nearly two decades ago. They’ve been effective in protecting email users from spam, phishing, and other email attacks.

To deliver your email reliably to receivers, you need to make sure that you are following best practices when it comes to email authentication. The use of two verification protocols, SPF and DKIM, are designed to ensure that the sender is authorized to send an email for a given domain. However, using two email authentication protocols complicates the already complex email environment. DMARC Record is an Email Authentication protocol standard released by DMARC Working Group. It aims to aggregate the authentication results from two popular email authentication protocols i.e SPF and DKIM. The DMARC Record notifies the ISPs about the email authentication process.

Every time you send an email, it includes a header that gives information about your email to the receiver. This header is what can be used to tell which emails are from real people and which are from automated systems. But, some spammer software doesn't include a valid sender address in this header, making it a red flag to a lot of email receivers.

Many email servers collect a variety of information to help determine whether a message should be delivered to the inbox. After collecting this information, servers take a few seconds to process all of the collected data and arrive at a decision. They use this delay as a chance to deliver the message immediately so that people don't have to wait too long for legitimate mail. Similarly, receiving domains resolve the listed IP addresses and check to see if any are blocked by their spam filters. In about an hour, you will know if your email was delivered or blocked from the sending domain's perspective.

It’s also tough to get feedback about email deliverability. So, deliverability issues can go undiscovered for weeks or months. This makes it even harder to sort legitimate emails from fraudulent emails.

All this makes receiving ISPs and ESPs hesitant to reject unauthenticated emails from senders that have very good reputations. A sender with a good reputation usually has their email authentication locked down.

Infosec Ventures cyber-security innovators that solve for inefficiencies in cyber security, solve big problems and deliver exceptionally high return on investment for customers. Infosec Ventures is on a mission to make the world cyber safe, by protecting systems and best practice that can be added to an email server's Domain Name System (DNS) records. It lets the owner of a domain inform other organizations on the Internet about how it wants to receive messages from them. If other organizations do not comply with the policy, the email message will bounce and/or get sent to a spam folder. This blog post will walk you through the process of creating and publishing your organization's DMARC policy.

DMARC is a protocol, which is designed to make it hard for malicious spammers and fraudsters and hackers and bots and fraudsters and people that want to intercept your email or impersonate you to do so. Above all, DMARC aims to improve the overall security of the Internet.

Working with your email provider to create a DMARC record is one of the top things you can do to ensure that you are handling your incoming mail properly, authenticating your domain, and setting expectations for how your domain should be treated. We’ll walk you through what a DMARC record is, why it’s important to have, and how to set one up on your domain

What is a DMARC Record?

There’s only one way to solve misunderstandings between sending and receiving mail servers. They must share information about their authentication infrastructures and what to do with unauthenticated emails. DMARC allows sending and receiving mail servers to share information about their authentication infrastructures and what to do with unauthenticated emails.

Your DMARC record represents the domain's policy on how it handles unauthenticated email. If your DMARC record is not properly set up, reports, important email reports, may never be received by you. If your domain is not properly protected by DMARC, spoofers can send email that looks like it is from you without the receiving server being aware of impersonation. Recognizing that email security is your chief concern, DMARC allows you to put in place a simple, effective and free method of reducing email-based fraud and spam. A DMARC (Domain-based Message Authentication, Reporting and Conformance) record specifies which authentication methods must be included in every message sent from your domain. When the receiving server receives the email, it then does a lookup for a DMARC record that will tell the receiving server what to do if a message fails DMARC.
