External Domain Verification in DMARC means confirming the legitimacy of outside domains sending emails on behalf of yours. It helps prevent email spoofing and phishing by making sure emails claiming to be from your domain are truly authorized.

Sender Policy Framework (SPF) traces its roots back to the early 2000s when email authentication became crucial to combat spam and phishing. SPF was created as an open standard to verify email senders and prevent domain spoofing. Over time, SPF evolved to tackle emerging email security challenges, gaining widespread adoption as an essential tool to validate the origin of emails and enhance the trustworthiness of email communication. The framework underwent refinements and expansions to accommodate advancements in email technology and combat increasingly sophisticated email-based threats, solidifying its position as a fundamental component of email security protocols.
