Tmail web interface won't load

[Turab]

I newly deployed v0.23.1 and set the server URL correctly. But after the Twake logo is shown, the Twake web UI never loads. It shows the loading animation forever. Different browsers won't help.

There are some CORS issues in the console (like webfinger etc.); but they are not vital. There are no issues on docker logs.

I also tried latest tag to no avail. So what can I do now? How do I diagnose the problem?

You can build a debug build, which has more verbose log output. Also, which server are you using? Does it set the ENV url correclty for the mailserver?

Also my build already has many of the issues fixed that Tmail has in compability wise with stalwart.

TMAIL current version is pretty much built on the James server, and therefore expect quite different parameters for auth etc from Stalwart, which stalwart does not provide

  SERVER_URL=https://mail.example.com/
  DOMAIN_REDIRECT_URL=https://mail.example.com
  WEB_OIDC_CLIENT_ID=tmail-web
  OIDC_SCOPES=openid,profile,email,offline_access

TMAIL docker 'env.file' config that works for me

• SERVER_URL - JMAP backend at
• WEB_OIDC_CLIENT_ID - OIDC client tmail-web for Stalwart authentication
• OIDC_SCOPES - Includes offline_access for persistent sessions
• FCM_AVAILABLE/IOS_FCM - Push notifications enabled

How do you then maintain the updates from the original branch?

[Tsopic]

When I reach a stable solution for myself, I would not care more about what they add, honestly.

If they add something useful that I need, i'll merge it. Feel free to do whatever you like, hope you get it running. You may also create PR-s from my code to linagora repo, if you are willing to spend that time on creating videos and demos. Either way i'll just add features that I need for compatibility with Stalwart and workflows and move forward with my life.

It was a configuration issue.

stalwartlabs/stalwart#513 (comment)

This setup needs CORS policy to be permissive, which should be enabled in Stalwart. Also an OIDC client must be registered with the same client ID defined in the Tmail env.file.

Not only these but also the domain redirect URL must be set to the webmail URL not the Stalwart URL and it MUST have an SSL certificate (even if a self-signed one), otherwise Stalwart will refuse to authorize.
