AWS Route53: Route53: clarify transfer authorization email senders and cancellation

Service: Route53 · 2026-09-27 · Documentation medium

File: Route53/latest/DeveloperGuide/domain-transfer-to-route-53.md

Summary

Reworded the ICANN authorization requirement from 'we must cancel the request' to 'we may cancel the change request', and expanded the list of legitimate authorization email sender addresses for .com.au/.net.au and other TLDs to include [email protected].

Security assessment

The change documents the legitimate sender addresses for domain-transfer authorization emails, which helps registrants recognize genuine authorization requests versus spoofed/phishing messages, and softens the stated cancellation consequence. It is security-adjacent guidance rather than a fix for a specific vulnerability.
