Google Workspace Changes

TLS and certificate validation are now enabled by default for new mail routes, with a new testing tool for admins.

Google has enabled Transport Layer Security (TLS) and certificate validation by default for all new SMTP mail routes in Gmail to enhance email security. To support this change, a new 'Test TLS Connection' feature has been added to the Admin console, allowing administrators to verify that a mail route can successfully establish a secure connection with a destination server before enforcing TLS, eliminating the need to wait for messages to bounce to confirm configuration.
