In today’s digital world, email security is more crucial than ever. One key player in the fight against email fraud is the DMARC (Domain-based Message Authentication, Reporting, and Conformance) record. A DMARC record is a DNS record that helps email receivers determine whether an email claiming to come from a specific domain is legitimate and what to do if it isn’t. This verification process is vital for protecting your brand from being used in phishing scams and ensuring that your emails reach your customers’ inboxes.

Why DMARC Is Important

DMARC safeguards your domain from unauthorized use, such as email spoofing, where attackers send messages with a forged sender address. By implementing a DMARC policy, you not only protect your brand’s integrity but also increase the deliverability of your emails. A DMARC policy tells receiving email servers how to deal with messages that fail DMARC checks, thereby minimizing the chances of your legitimate emails being marked as spam.

The Three Policy “p=” Options in DMARC

DMARC policies are defined by the “p=” tag in the DMARC DNS record, which instructs email receivers how to handle emails that fail DMARC checks. There are three options:

  • p=none: This is the monitoring mode, where no action is taken against emails that fail the DMARC check. Instead, reports are sent back to the sender, providing visibility into who is sending emails on behalf of the domain.
  • p=quarantine: Emails that fail the DMARC check are moved to the spam folder or otherwise quarantined. This option is more protective than p=none, helping to prevent malicious emails from reaching recipients’ inboxes.
  • p=reject: This is the most secure setting, where emails that fail the DMARC check are outright rejected. This prevents phishing emails from being delivered entirely.

Caution Before Moving Beyond “p=none”

Several major email platforms, including Google and Yahoo, now require DMARC records for domains sending more than 5,000 emails a day to their users. This measure is to ensure that large volumes of email are authenticated, reducing the risk of spam and phishing attacks.

However, it’s crucial to proceed with caution before setting your DMARC policy to anything beyond “p=none”. Incorrectly configuring your DMARC policy to “p=quarantine” or “p=reject” without proper validation can lead to legitimate emails being blocked or failing to be delivered.

At myshophosting, we understand the intricacies involved in DMARC implementation. We offer a specialised DMARC implementation service designed to test all your email sources for compliance before moving to a more restrictive DMARC policy like “p=reject”. This ensures that your legitimate emails continue to reach their intended recipients without interruption, while effectively blocking fraudulent activity.
