This is a beta of XOAUTH2 authentication for SMTP email sending.
I have tested it works with Office365 email address, using Azure AD. Other service providers (Google, Yahoo) can be added in future as needed, I've provided a comment where in the mailHelpers.php file this should go.
This implementation shouldn't not affect existing plain/login authentications of SMTP (I tested this).
