I extended build_message (the pure function) with cc, bcc, in_reply_to, and references, wired the matching --cc/--bcc (repeatable), --in-reply-to, and --references flags through cmd_send, and wrote the tests first. send_message derives recipients from the To/Cc/Bcc headers and strips Bcc, so no manual recipient list is needed. 2026-05-15T21:56:39+00:00 Craig Jennings c@cjennings.net 2026-05-15T21:56:39+00:00 urn:sha1:c1d4e3c4a42abd01bc7ef83b1d6ae036ee32ef1d
