 * From and Reply-To, taken from the mailbox behind a purpose.

 * Reply-To is the whole reason sending alone is enough: a customer answering a
 * support reply lands in the support mailbox, read in an ordinary mail client,
 * so no IMAP is needed to close the loop.
 *
 * Except on a no-reply mailbox. A "no-reply" address you can reply to is a lie
 * in the sender, and the one place the promise is made is the address itself.
