OpenMail plugin for Hermes Agent gives a Hermes bot an email address: incoming mail is a wake-up call, and the agent's reply goes back down the same thread as the outgoing message. Installation goes through the Hermes plugin catalog (hermes plugins install openmail --enable), a one-command setup wizard (hermes openmail setup) that requests an OpenMail API key and picks or creates an inbox, and the existing hermes gateway run gateway process; a doctor subcommand checks the result at any time. Access control runs in two layers. OpenMail's own allow/block rules apply first on the server side, then Hermes checks its own sender list: either an explicit OPENMAIL_ALLOWED_USERS allowlist or a flag that defers entirely to OpenMail's console-configured sender rules. Unknown senders are dropped without any pairing flow reaching them by mail. Three modes control how inbound mail is handled, set globally or per inbox in config.yaml: channel mode starts a normal agent turn and mails the reply back; notify mode summarizes without acting and forwards the summary to the operator's own chat platform instead of the sender; tool mode ignores inbound mail entirely and exposes the mailbox only as tools the agent can call on request. OpenMail's own message classifier filters marketing, automated and bounce mail into notifications and drops spam and malicious mail outright before it reaches the agent. The plugin registers an openmail toolset so the agent can act on its own: listing usable inboxes, sending new threads, replying within an existing thread, listing and reading messages, and extracting text from attachments. The API key is scoped to the chosen inbox or pod rather than the full account and never enters the model's context window, limiting what a compromised agent session could expose.
