Setting up your business email and domain on platforms like Microsoft 365 (M365) is essential for a professional digital presence. However, without the right security configurations, you’re leaving your business open to risks like phishing, spam, and domain spoofing. For small and medium-sized enterprises (SMEs), the stakes are especially high, as any breach can harm customer trust and the business’s reputation.
Implementing security protocols like DKIM (DomainKeys Identified Mail) and DMARC (Domain-based Message Authentication, Reporting, and Conformance) is one of the most effective ways to protect your business’s domain and email security.
Why Email Security Matters
For any organisation, email is a primary communication channel—and that makes it a top target for cyber threats. By failing to set up essential email security protocols, businesses risk their emails being intercepted, misused, or sent without verification. For SMEs, the potential consequences are significant, ranging from financial loss to a damaged reputation. Here’s how DKIM and DMARC work together to protect your domain and email setup:
1. DKIM: Adding a Layer of Authenticity
DKIM uses encrypted digital signatures to verify that emails coming from your domain are genuinely yours. This helps prevent attackers from sending emails on your behalf, a common tactic in phishing schemes. With DKIM in place, recipients can trust that an email from your domain hasn’t been tampered with or spoofed.
2. DMARC: Gain Visibility and Control
DMARC adds an extra layer by providing visibility into how your emails are being sent and received. Through DMARC reports, you can monitor email activity, identify potential issues, and set policies on how to handle unauthenticated emails. Implementing DMARC gives you more control over your domain’s email reputation, reducing the risk of your emails being flagged as spam or, worse, impersonated by malicious actors.
Benefits of DKIM and DMARC for SMEs
For smaller organisations, these protocols offer tangible benefits that go beyond security:
- Protect Customer Trust: By securing your email communications, you build and maintain customer confidence in your brand.
- Improve Deliverability: Authentic emails are more likely to reach their intended recipients, reducing the risk of ending up in spam folders.
- Reinforce Brand Protection: Unauthorised use of your domain is minimised, preserving your brand reputation.
Best Practices for Setting Up DKIM and DMARC
When configuring DKIM and DMARC for M365 or any other email service, follow these best practices:
- Use a Secure DNS Provider: Set up both protocols through a reliable DNS provider to ensure accurate configuration and reliable performance.
- Set Up Regular Monitoring: Review DMARC reports regularly to spot suspicious activity and address potential threats quickly.
- Start with a Test Phase: Implement these protocols in monitoring mode initially to understand the impact on email deliverability and fine-tune settings if needed.
