Email Security update for our clients

As part of our ongoing commitment to ensuring the highest level of security for your communications, I have recently implemented SPF, DKIM, and DMARC anti-spoofing protection for our Microsoft 365 & Google Workspace email accounts.

In today's digital landscape, protecting your business from email spoofing, phishing attacks, and unauthorized use of your domain is of utmost importance. These three protocols—Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC)—work in tandem to significantly enhance the security of your email communications.

Here's a brief overview of each protocol and the benefits they provide:

SPF (Sender Policy Framework):

SPF is an email validation protocol that helps detect and prevent email spoofing. By configuring SPF records for your domain, we ensure that only authorized email servers are allowed to send emails on your behalf. This prevents malicious actors from impersonating your domain and helps maintain the integrity of your email communications.

DKIM (DomainKeys Identified Mail):

DKIM adds an extra layer of security to your email messages by digitally signing them using cryptographic signatures. These signatures can be verified by receiving mail servers, ensuring that the emails you send are genuine and haven't been tampered with during transit. DKIM helps establish trust with your recipients and reduces the likelihood of your emails being flagged as spam.

DMARC (Domain-based Message Authentication, Reporting, and Conformance):

DMARC builds upon SPF and DKIM by providing a policy framework for email authentication and reporting. It allows you to specify how your domain handles emails that fail SPF or DKIM checks, giving you greater control over the handling of potential phishing attempts. DMARC also provides detailed reports on email authentication results, enabling you to monitor and analyze email activity related to your domain.


By implementing these robust anti-spoofing measures, we are taking proactive steps to safeguard your email communications. With SPF, DKIM, and DMARC in place, you can have increased confidence that the emails you send and receive through your email accounts are authentic, secure, and less susceptible to phishing attacks.


We understand the importance of maintaining uninterrupted service during this implementation. Rest assured that these security enhancements have been seamlessly integrated into our systems without causing any disruption to your email services. However, if you encounter any issues or have any questions regarding these changes, please don't hesitate to reach out to us directly.


We highly recommend that you also take some additional measures to protect your own email security. Educating your employees about email best practice and being vigilant about suspicious emails or links are all essential steps in maintaining a secure digital environment. There are a number of online materials available for Cyber Security and Essentials training which we encourage you all to look into.
