SPF (Sender Policy Framework) and DMARC (Domain-based Message Authentication, Reporting & Conformance) are protocols used to authenticate email messages and protect against email spoofing, a standard method used in phishing and spam.
Both SPF and DMARC are set up in your DNS as TXT records. They are crucial components of email security and help protect against malicious activities like phishing and spoofing. They also aid in improving the deliverability of your emails, as many email providers check for these records to determine if an email is legitimate.
Risks of Misconfigured SPF & DMARC Records
Email Deliverability Issues: If SPF and DMARC records are not correctly configured, your legitimate emails may be marked as spam or even rejected by the recipient's mail servers. This can lead to critical communications not reaching your customers or partners, which can have profound business implications.
Spoofing and Phishing Vulnerabilities: SPF and DMARC are essential tools to prevent others from sending emails that appear to come from your domain (spoofing). If these records are misconfigured, it can leave your domain vulnerable to being used in phishing attacks. This can harm your organization's reputation and potentially lead to your customers or partners falling victim to scams.
Loss of Visibility: Part of the value of DMARC is its reporting function, which provides visibility into how your domain is being used (or misused) in email. If DMARC is misconfigured, you may not receive these reports, losing valuable insights into potential security issues.
Potential for Blacklisting: If your domain is used to send spam (whether by you or a malicious actor exploiting a misconfiguration), it can end up on email blacklists. This can make it much harder for legitimate emails to reach their recipients, even after resolving the issue.
Violation of Compliance Requirements: Depending on your industry, you may be subject to regulations requiring specific steps to secure your email. A misconfiguration in your SPF or DMARC records could put you in violation of these regulations, leading to penalties.
