Sender field
RFC 5322 differentiates between the author and the sender of a message. The person who writes the message is usually also the one who sends it. If the author and the sender are different, though, the sender should be provided in the Sender field. The standard also allows several addresses in the From field. If this is the case, the email must include a Sender field with a single address. However, I’m not aware of any mail clients which support this. In practice, the addresses of the co-authors are simply added to the Cc field. Their contribution is made clear to the primary recipients by mentioning the names of all the authors at the end of the message. Remember that a sender can lie about their co-authors: The fact that a person’s address is listed in the Cc field doesn’t imply that the email has been delivered to them and that they agree with the content of the message.
