Sends a reply to a specific message in a conversation, from the mailbox's own address. Recipients are derived from the message being replied to — its Reply-To address when present, otherwise its From address; set reply_all to also include the original To and Cc recipients. The subject and the threading headers that keep the reply in this conversation are set automatically, and the reply is recorded in the conversation. To reply to a conversation as a whole, target its newest received message.
