You might have heard that you do not necessarily need all three email authentication protocols— SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) to create a foolproof defence strategy for your email ecosystem. But here’s a truth that these custodians of security do not tell you: achieving a 100% foolproof email security strategy is very challenging, if not impossible, and you need a multi-layered approach that covers all the bases and helps you stay ahead of these attacks.
Here’s a question for you: how much security is too much security for your emails? Before you try to answer this question, we would like to remind you that email security threats like phishing, spam, ransomware, malware, and spoofing are not only becoming more frequent but also more grave. The kind of impact these attacks have on the target is often devastating, including financial loss, data breach, and legal consequences. With these threats looming over your email ecosystem, you need a mechanism that is robust and hardy.
Emails were and still are a crucial tool for business communication and marketing.
A report by Statista revealed that in 2023, about 347 billion emails were sent and received globally daily. That figure is projected to increase to about 392 billion daily emails by 2026.

SPF=fail, but the recipient’s mailbox has not quarantined or rejected the email- why?
by Duocircle
When an email shows ‘SPF=fail’ but is not blocked by an antispam filter, it can be due to several reasons. Knowing and fixing the issue is important; otherwise, threat actors can exploit the security gap by sending fraudulent emails in your business’ name.
Enabling Microsoft’s Exchange Online Protection (EOP) phishing policies using the Microsoft Defender portal
by Duocircle
There is a default anti-phishing policy that is applied to all recipients, but it’s better to create custom policies for better protection. To configure the anti-phishing policies, you need to be assigned permissions in the Microsoft Defender portal. If you have the required permissions, you are good to go ahead and make modifications.

The wave of DMARC adoption was such that over 800,000 new DMARC records were created by March 2024. And just like the rest of the world, organizations in Ireland also jumped on this bandwagon.
Why does RFC impose the character limit on SPF records?
