With a new feature added to Thexyz email security strategy, you can now enable DomainKeys Identified Mail (DKIM) signing for your domain’s email.
What is spoofing?
When email was developed in the 1970s, security was not such a major concern as such a few people used it and most of the people actually knew the sender of the email. Today email is a widely used and necessary business communication tool for both internal and external messaging.
Email is also widely used to mislead, steal, and extract money from businesses and individuals. This is known as “spoofing” and is easy to do as many email providers and clients By default, email clients only show a few lines, such as the envelope-from address. The header-from address could be a completely different envelope-from address which is why so many people get caught out by spoofing, as it appears to come from a trusted sender. Such malicious behavior can affect the trust people place in the safety of email
It’s also created the need for you, as a domain owner, to protect against impersonation and provide a level of assurance about the authenticity of
email you send to your clients.
What is DKIM?
DomainKeys Identified Mail (DKIM) uses cryptographic keys to add signatures on emails, which can be verified with a cryptographic public key in DNS by receiving mail servers.
DKIM is an important step towards securing your email as a proven feature that’s been fully embraced by the email industry. As it is now a common and standardized method for providing a public/private key mechanism among email providers.
DKIM authentication is based on the premise that only authorized senders have the information necessary to create a valid signature for your domain. Email providers that receive email can then validate the DKIM signature from your domain’s DNS.

DKIM at Thexyz
Here at Thexyz, we recommend utilizing DKIM as part of a larger email security strategy which includes other features, such as adding Sender Policy Framework (SPF) and Domain Message Authentication Reporting and Conformance (DMARC).
By enabling DKIM on your domain, it will add a secure signature to all outgoing messages sent from your domain. Utilizing a public/private key
mechanism, this signature allows recipients to authenticate that the message was sent from a trusted and approved service.
See this guide for adding DKIM to your domain. If you would like more information or assistance in enabling DKIM authentication for your domain’s email, please contact Thexyz Support Team.
