How to protect your company email from hacking

In today’s digital age, ensuring the security of your company’s email communications is paramount. Whether you’re looking to protect your company email or simply increase email deliverability, implementing DMARC (Domain-based Message Authentication, Reporting, and Conformance) protections for your domain is a crucial step. In this comprehensive guide, we’ll walk you through the process of adding DMARC protections to your domain, step by step.

Introduction to DMARC

DMARC is an email authentication protocol designed to protect your domain from email spoofing, phishing, and other unauthorized uses of your domain name. By implementing DMARC, you can prevent cybercriminals from impersonating your domain and help ensure the integrity of your email communications.

Step 1: Access Your Domain’s DNS Settings

To begin adding DMARC protections to your domain, you’ll need access to your domain’s DNS (Domain Name System) settings. These settings allow you to configure the DNS records that control how your domain is identified and accessed on the internet.

Step 2: Setting Up SPF (Sender Policy Framework)

What is SPF?

SPF, or Sender Policy Framework, is an email authentication method that allows you to specify which mail servers are authorized to send emails on behalf of your domain.

SPF (Sender Policy Framework)

How to Set Up SPF

  1. Log in to your DNS provider’s website.
  2. Navigate to the DNS management section.
  3. Locate the SPF record settings for your domain.
  4. Add a new TXT record with the following information:
   Name: @
   Type: TXT
   Value: v=spf1 include:_spf.google.com ~all

Replace _spf.google.com with the appropriate SPF record for your email service provider.

Step 3: Setting Up DKIM (DomainKeys Identified Mail)

What is DKIM?

DKIM, or DomainKeys Identified Mail, is an email authentication method that allows you to sign outgoing emails with a digital signature. This signature verifies that the email was sent from an authorized mail server.

How to Set Up DKIM

  1. Log in to your email service provider’s admin panel.
  2. Navigate to the DKIM authentication settings.
  3. Generate a new DKIM key for your domain.
  4. Add a new TXT record to your DNS settings with the DKIM key.

Step 4: Setting Up DMARC (Domain-based Message Authentication, Reporting, and Conformance)

What is DMARC?

DMARC, or Domain-based Message Authentication, Reporting, and Conformance, is an email authentication protocol that builds on SPF and DKIM to provide further protection against email spoofing and phishing attacks.

What is DMARC?

How to Set Up DMARC

  1. Log in to your DNS provider’s website.
  2. Navigate to the DNS management section.
  3. Add a new TXT record with the following information:
   Name: _dmarc
   Type: TXT
   Value: v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com; ruf=mailto:dmarc@yourdomain.com; fo=1

Replace yourdomain.com with your actual domain name.

Step 5: Monitoring and Analyzing DMARC Reports

Once you’ve set up DMARC for your domain, it’s essential to monitor and analyze the DMARC reports to ensure that your email communications are secure.

It’s recommended to monitor your DMARC reports regularly, ideally on a daily basis. By monitoring your DMARC reports regularly, you can quickly identify and respond to any issues or security threats.

Can I use EasyDMARC to monitor multiple domains?

Yes, EasyDMARC allows you to monitor multiple domains from a single dashboard. Whether you have one domain or multiple domains, EasyDMARC makes it easy to monitor and analyze your DMARC reports.

What is the difference between SPF, DKIM, and DMARC?

  • SPF (Sender Policy Framework) specifies which mail servers are authorized to send emails on behalf of your domain.
  • DKIM (DomainKeys Identified Mail) adds a digital signature to outgoing emails, verifying that they were sent from an authorized mail server.
  • DMARC (Domain-based Message Authentication, Reporting, and Conformance) builds on SPF and DKIM to provide further protection against email spoofing and phishing attacks.
