Deploying and configuring DKIM, along with implementing DMARC, is critical for Salesforce users to protect their domain’s reputation, improve email deliverability, and maintain the integrity and authenticity of their email communication. DKIM and DMARC work together by integrating cryptography and policy-based authentication to verify if a cybercriminal changed an email’s content or spoofed the sender…
DKIM is a cryptography-based email authentication protocol that allows the receiving server to check whether an email coming from a specific domain is officially authorized to send emails. If your domain has DKIM, then whenever you send an email, your server will attach a digital signature to the header. This signature is produced using a…
As you know, DKIM catches alterations made to emails during their time in transit. It performs authentication checks by attaching a digital signature to the header of each email that goes from your domain. Upon reception, the receiving server verifies the sender’s legitimacy using the public key published in the sending domain’s DNS. However, when…
To configure DKIM for Amazon SES, you have to modify the DNS settings of your domain. For Route 53 users, Amazon SES will take care of the process, but if you use another DNS provider, you need to follow some processes. Here are rules that you need to abide by: Configuring DKIM for a Domain…
If you thought that authentication standards like Domain-based Message Authentication, Reporting, and Conformance (DMARC) and Brand Indicators for Message Identification (BIMI) were enough to maintain the integrity of your email communication, you are probably mistaken! According to a recent report published by Estonian security researchers, there exists a significant flaw in the DomainKeys Identified Mail…
There is a multi-step journey between your outbox and the recipient’s inbox. Since the process is very quick, we don’t realize that when an email is in transit, it’s prone to tampering and modifications by malicious actors. You can deploy DKIM (DomainKeys Identified Mail) to ensure nobody tampers with your emails in transit and prevent…
Deploying and configuring DKIM on Google Workspace is a two-step process, and administrators often skip the second step. In such cases, DKIM and DMARC function properly, and email delivery is not impacted either. However, DKIM doesn’t authenticate emails using your custom domain. Let’s see what these two steps are and how you can avoid breaking…
In 2023, as many as 45.6% of total emails were identified as spam. While CISOs and technology enthusiasts are trying their best to ward off these attacks, cybercriminals are not behind in exercising their brain muscles to come up with newer ways of exploitation. One such relatively recent technique is a DKIM replay attack, where…
When it comes to email authentication, SPF offers different result qualifiers to indicate how the receiving mail server should handle emails that are outside of the list mentioned in the SPF record of the sending domain. These result qualifiers are SoftFail and HardFail. There is no hard-and-fast rule as to which one’s the better choice…
Now that DMARC implementation has become a norm in 2024, it is important that you understand its nuances to make informed decisions and fortify your organization’s defenses. One of the integral aspects that determine the efficacy of DMARC authentication is choosing the right DMARC alignment mode. When it comes to DMARC alignment, choosing between relaxed…
