Email MCP server for Gmail, Outlook and any IMAP mailbox, hardened against prompt injection

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.
const child = spawn(command, args, { stdio: 'ignore', detached: true })
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
EMAIL_USER (Account login.), EMAIL_PASSWORD (App password. Either this or EMAIL_PASSWORD_CMD is required, except with PROVIDER=outlook, which signs in through the browser.), PROVIDER (One of gmail, outlook, icloud, yahoo, gmx, fastmail, mailbox.org, posteo. Fills in IMAP, SMTP and Sieve hosts and ports.), IMAP_HOST (IMAP hostname for self-hosted or unlisted providers. Overrides the preset.), CAPABILITIES (Comma-separated list of tiers beyond read, which is always included. Defaults to drafts.), MS_CLIENT_ID (With PROVIDER=outlook only. Application ID of an app registered in your organization's tenant.), MS_TENANT (With PROVIDER=outlook only. Tenant ID or domain, for a single-tenant MS_CLIENT_ID.).
The author declared them in the registry entry; get the values from the project itself.
