Google and Yahoo’s New DMARC Policy<\/h2>\n
Google and Yahoo, two of the world’s leading email providers, have introduced a new DMARC policy<\/strong> effective from February 2024. This policy requires email authentication, particularly affecting businesses that send emails via Gmail and Yahoo Mail.<\/p>\nUnderstanding DMARC<\/h3>\n

The Email Spoofing Issue<\/h4>\n
Imagine receiving an email that appears to be from your bank, requesting urgent action. You click a link, enter your details, and suddenly your information is compromised. This is a classic example of email spoofing<\/strong>, where scammers disguise their email addresses to seem legitimate, mimicking trusted individuals or organisations.<\/p>\nConsequences of Email Spoofing:<\/strong><\/p>\n\n- Financial losses<\/li>\n
- Reputational damage<\/li>\n
- Data breaches<\/li>\n
- Loss of future business<\/li>\n<\/ul>\n
As email spoofing becomes more common, email authentication emerges as a vital defence mechanism for businesses.<\/p>\n
What is Email Authentication?<\/h3>\n
Email authentication verifies the legitimacy of your emails by checking the server sending them and reporting any unauthorized use of your domain. It involves three key protocols:<\/p>\n
\n- SPF (Sender Policy Framework):<\/strong> Lists the IP addresses authorized to send emails for your domain.<\/li>\n
- DKIM (DomainKeys Identified Mail):<\/strong> Allows domain owners to digitally sign emails, verifying their legitimacy.<\/li>\n
- DMARC (Domain-based Message Authentication, Reporting, and Conformance):<\/strong> Provides instructions to receiving email servers on handling emails based on SPF and DKIM checks and alerts domain owners of any spoofing attempts.<\/li>\n<\/ol>\n
