Install
Install chainmail with Homebrew, from a release archive, with Nix, or from source.
Quick start
Run a development daemon as your own user, add an account and try the first commands.
Accounts and providers
Configure Google Workspace, Gmail, iCloud, Hostinger and other IMAP and SMTP accounts, and store their secrets in the vault.
Connect an agent
Register chainmail mcp with an AI agent's MCP client so the agent can read, send and organize mail through the daemon.
