Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Mail-in-a-Box, so you can see the experience inside your AI.

It does not authenticate your account with Mail-in-a-Box. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ

Questions Mail-in-a-Box owners ask.

  • 01

    What format is required for the instance host?

    Provide the full hostname without the 'https://' prefix, for example: box.yourdomain.com.

  • 02

    Can I add multiple forwarding targets to an alias?

    Yes, when using the create_or_update_alias capability, provide a comma-separated list of emails in the forwards_to field.

  • 03

    Does this work with 2FA enabled accounts?

    The current API implementation uses Basic Auth. If 2FA is enabled on your admin account, you may need to use an API key or a dedicated admin user without 2FA for the integration.
