A permerror in SPF indicates that there is a permanent error with the Sender Policy Framework (SPF) records, preventing proper interpretation of your domain’s email authorization. To resolve this issue, you should ensure that there are no multiple SPF records for your domain, check for syntax errors in the existing record, and limit the number of DNS lookups to comply with the SPF specification, which means using efficient mechanisms and avoiding unnecessary complexity.
DMARC TempErrors refer to temporary authentication issues related to email standards such as DKIM and SPF, which can lead to failures in DMARC validation. These errors can result in sporadic email delivery problems, particularly when using Microsoft servers, and addressing them may involve utilizing monitoring services like dmarcian.com for insights into performance metrics and error diagnostics.
Your wait is over as we’re back with cybersecurity’s latest this week!

Let’s not wait further and dive in!
A DKIM selector is a string included in the DKIM signature of an email, which helps the recipient’s mail server locate the corresponding public key stored in DNS records for verification purposes. It is essential for ensuring that emails sent from your domain can be properly authenticated, thereby enhancing your email security and integrity.

Threat actors are exploiting Google Calendars for phishing and spoofing attempts

Threat actors are becoming more sophisticated, and the safety of the digital space is taking a toll because of it. Over the past few months, cybersecurity experts have noticed a new phishing scam tactic in which bad actors send fake meeting invitations that redirect the invitees to phishing websites. These invites look exactly like the original Google invites, and even the phishing website is cloned so well that it’s difficult to catch its fakeness. Since the counterfeit platforms are flawless, the success rate of these attacks is extremely high; users are entering sensitive details and downloading malicious links without batting their eyes.
In today’s fast-paced tech world, many businesses are seeking ways to streamline their IT services and improve customer satisfaction, but how do they do that effectively? Enter the MSP Partner Program—a game-changing initiative specifically designed for Managed Service Providers (MSPs).
The ‘fo’ tag in DMARC stands for ‘failure options.’ It’s an optional tag that helps domain owners specify the types of authentication and alignment issues that must be reported. This tag supports four specific types of failure reports: fo=0, fo=1, fo=d, and fo=s. The ‘fo’ tag can combine multiple reporting options, enabling you to create a customized reporting strategy that aligns best with your preferences and risk tolerance.
In a digital world where email is still a primary mode of communication, protecting your domain from malicious attacks has never been more critical. You may think email security only pertains to big corporations, but every organization, large or small, should be on alert against threats like phishing and spoofing.
