Natural disaster with a tornado near the house in the field.

In the contemporary digital era, email is one of the primary methods of communication employed to achieve personal and professional goals. Email scams, phishing attempts, or other illegal activities have increased along with the usage of email. To protect your domain and guarantee secure email delivery, it is crucial to verify your email.

In this blog, we’ll go through the basics of email authentication. Also, provide you with the tools and knowledge you need to safeguard your domain.

Types of Email Authentication.

We are a part of technology, which is modifying our way of life in response, and it is continually on the verge of making the impossibly conceivable. We can now do financial tasks online with just one click, saving us the time and effort of going to the bank. Technology has revolutionized many important parts of our lives. Unfortunately, some people have attempted to impersonate others using this technology for evil. So, in addition to using technology to our advantage, it is our duty to safeguard ourselves from its abuse. Thankfully, these technical advancements allow us to develop security techniques that reduce the possibility of being faked.

Here are a few suggested solutions that can significantly alter your security procedures for verifying email communications.

  • SPF – A domain owner can select which mail servers are permitted to send emails on their behalf using SPF (Sender Policy Framework), a sort of email authentication. By issuing an SPF record in their domain’s DNS, domain owners can specify which servers are permitted to relay email for their domain to receiving mail servers. If a message originates from a server that isn’t included in the SPF record, it can be flagged as possibly fraudulent.
  • DKIM – Another email authentication method is DKIM (Domain-Keys Identified Mail), which enables domain owners to “sign”….. their emails using digital signatures. When a recipient mail server receives a signed message, it may verify the message’s signature and that the domain owner sent it through the use of the domain owner’s public key.
  • DMARC – It is a technique for email authentication that is based on SPF and DKIM. DMARC or Domain-based Message Authentication, Reporting & Conformance enables domain owners to define a procedure for handling messages that fail SPF or DKIM verification by receiving mail servers. Alternatives to this may include not delivering the communication, placing it in quarantine, or even outright dismissing it.

Consequences if you lack Email authentication.

Lack of email authentication might result in a variety of problems, including:

  • Without email authentication, it is simpler for criminals to send spam and phishing emails that appear to be from your domain, which can hurt your reputation and even your customers.
  • Email authentication ensures that your emails reach their intended recipients and prevents email delivery issues. Your emails can be rejected or labelled as spam more frequently without it.
  • Impersonation of your brand. Without email authentication, it’s simpler for someone to use your brand’s name to send false emails to your consumers, harming your reputation and creating confusion.
  • Email account hijacking. Email authentication offers some defence against account takeover. Without it, a hacker may access your email and use it to send phishing or spam emails.

A crucial security measure, email authentication protects your brand, clients, and email interactions.  If you haven’t already, it’s imperative that you take this action.

How does an email authentication work?

A mail server initially looks for a valid SPF record when it receives an email message. If the check fails, the server rejects the message or flags it as suspicious. The server looks for a valid DKIM signature if the check is successful. The server rejects the message or flags it as suspicious if the DKIM check fails. The server verifies the DMARC record to ascertain the domain owner’s policy on how to handle messages that pass or fail SPF and DKIM checks, once they have passed both SPF and DKIM tests.

The server handles the message as though it had failed the SPF or DKIM tests if the domain owner has so far not published a DMARC record or if the DMARC check is unsuccessful.

Domain owners may defend their domains against spam and phishing assaults by using SPF, DKIM, and DMARC. This can ensure that their valid email messages get into the inbox. By putting these principles into practice, email communication can be made more secure, and domain email may be shielded from malicious intent.

Keep your domain safe with these best practices:

  • Keep your DNS records and email server software up-to-date. This will ensure that they are not vulnerable to known security vulnerabilities.
  • Use an email authentication service provider such as EmailAuth, which implements advanced security measures to protect your domain from email-based threats.
  • Keep your domain registration information accurate and up-to-date.
  • Use strong passwords and two-factor authentication for all email accounts associated with your domain.
  • Regularly monitor your domain’s email traffic for any signs of abuse or unauthorized use.
  • Implement SPF, DKIM, and DMARC to authenticate your email and prevent phishing and spam.
  • Regularly back up your website and important data.
  • Have a disaster recovery plan in place in case of a security breach or other emergency.
  • Train your employees on security best practices and keep them informed about the latest threats and how to protect your domain.

By implementing these best practices, you can help protect your domain from various types of cyber threats and ensure that your website and email remain available and secure.

Want an extra layer of email authentication?

Introducing you to Brand Indicators for Message Identification (BIMI) – a standard that allows email domains to publish a logo. This logo may appear next to emails sent from the domain in the inbox from the email provider. As a result, receivers can immediately and simply recognize communications coming from reliable sources. Phishing and other forms of email fraud are also deterred.

In order for BIMI to function, a validated logo must be published in a domain’s DNS records. The logo is retrieved by email providers from participating websites in order to increase the sender’s visibility and authority. They then show it in the inbox next to the emails that were sent from that site. The logo has to be validated by an established third party in order to be BIMI-compliant. For instance, a certificate authority must adhere to strict size, format, and file type requirements.

BIMI offers an extra degree of protection in addition to giving receivers a visual signal. By enabling the BIMI record check and limiting the display of the logo to communications that successfully pass DMARC authentication by email providers,

Finally, the BIMI standard allows email domains to add their company logo to the inbox next to their messages. This seeks to give users an additional degree of protection and enhance brand awareness.

Given that we live in a virtual era where civilizations can be annihilated with a single click and individuals may be exploited with a mouse button, you should strengthen your defences.
