Dear all,
A feature request.
In this day and age, wouldn’t it be good if the SMTP Server were updated to include additional support for ex. Microsoft Graph, API, or something modern? Soon, outdated protocols will no longer be allowed, and we won’t be prepared for tomorrow?

I think you are confusing issues. SMTP is a universal standard required for different networks to talk to each other. Replacing it with an API like Microsoft Graph would break email, making it impossible to send messages outside of that specific ecosystem.
The concern about outdated protocols actually confuses the email protocol itself with how systems log into it. Providers like Microsoft and Google are not phasing out SMTP; they are simply turning off insecure, basic authentication that relies on plain usernames and passwords.
SMTP has already been updated for the modern era through OAuth 2.0, which secures connections using modern tokens. As long as sending applications use this modern authentication to connect to SMTP, the setup is secure and fully prepared for the future.
@eko I think we’re talking about two different things. I fully agree that SMTP itself is not obsolete and that Microsoft is not replacing SMTP with Microsoft Graph.
My point is that Manager.io currently appears to support only SMTP authentication using a hostname, port, username and password. Unless I’m mistaken, there is currently no support for SMTP with OAuth 2.0 authentication.
Since Microsoft and Google are moving away from Basic Authentication, my feature request is actually for support of modern authentication (OAuth 2.0) for SMTP, or alternatively support for APIs such as Microsoft Graph where appropriate.
If Manager.io already supports SMTP with OAuth 2.0, then my understanding is incorrect and I’d appreciate clarification.
You are entirely correct. Manager.io currently only supports traditional SMTP input fields (host, port, username, password) and lacks native support for OAuth 2.0 interactive authentication or specific integration APIs like Microsoft Graph. Your feature request for modern authentication is completely valid.
To clarify how users are currently connecting to Microsoft 365 and Google Mail without native OAuth 2.0 support: they rely on App Passwords (or app-specific passwords).
When Google and Microsoft deprecate basic authentication, they block your regular account password from being used in standard fields. However, they explicitly permit third-party applications to connect via SMTP if the user generates a dedicated, isolated 16-character App Password through their account’s security console. This bridges the security gap because generating the App Password requires multi-factor authentication, satisfying modern security compliance without requiring the application itself to support an interactive OAuth web prompt.
While App Passwords keep standard SMTP active and functional in Manager.io today, adding native OAuth 2.0 or modern API support would certainly be a great forward-looking improvement for the software.
So i put it in the ideas category.
