Frequently asked questions about the Mail-in-a-Box MCP Server

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 tool, 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.
