SMTP OAuth Authentication Support for Microsoft 365

I would like to request support for SMTP authentication via OAuth for Microsoft 365 accounts.

Microsoft is gradually deprecating basic SMTP authentication (username and password) to improve security and better protect accounts from misuse. As a result, many organizations are required to switch to OAuth-based authentication for sending emails.

Currently, I do not see an option to configure OAuth authentication for SMTP. Adding support for OAuth would allow users to continue sending emails from their custom domains through Microsoft 365 while complying with Microsoft's modern authentication requirements.

This feature would help ensure long-term compatibility with Microsoft 365 and provide a more secure authentication method for email delivery.
