Connect your Spacemail mailbox in Aquila

Choose Spacemail in the host grid. Aquila fills the provider settings automatically.

Open the dashboard and choose Add inbox.
Select the provider card when it is available, or use Other IMAP for custom settings.
Enter an inbox name, email address, and mailbox password or app password.

Test and save the mailbox

Aquila tests the incoming IMAP connection and, when SMTP is enabled, the outgoing SMTP connection before saving credentials.

Use the credential Spacemail expects for IMAP and SMTP access.
A successful test confirms that the agent can reach the mailbox through Aquila.
Mailbox credentials are encrypted at rest and decrypted only for request-time access.

Create an API key for ChatGPT

Create a dedicated API key for each agent or workspace so access can be audited, scoped, and revoked independently.

Name the key after the agent or environment that will use it.
Select only the mailboxes this key should expose.
Optionally set an expiration date for temporary projects or contractor access.

Add Aquila as an MCP server in ChatGPT

Use the Aquila MCP endpoint and the API key you created. The endpoint is http://localhost:8080/mcp.

Use an Authorization bearer token header with the API key.
Keep the API key secret. Aquila only shows it once after creation.
After connecting, ask the agent to list connected email addresses to verify access.

Reusable MCP configuration block

Use this block in every guide and replace the API key placeholder with the one-time key copied from Aquila.

{
  "mcpServers": {
    "aquila-email": {
      "url": "http://localhost:8080/mcp",
      "headers": {
        "Authorization": "Bearer <your aqla_ API key>"
      }
    }
  }
}
