POST
Reply To Message
Replies to one message, threading the response correctly, and returns message_id and thread_id. 🔴 This sends real email and it cannot be recalled. It answers the sender only — post_agentmail_inbox_message_reply_all answers every recipient, which is a materially different blast radius, so pick deliberately. Every AIsa caller shares one AgentMail account, so this reaches inboxes other callers created. To send to a fresh set of recipients use post_agentmail_inbox_message_send.
