new-message-id
Generates and returns a new value for the Message-ID header field. You can use this value to populate the header of a MIME message. This function, unlike current-message-id, always returns a new Message-ID. The Message-ID has the following format:
'<' UTC timestamp '-' random hex value 32 characters long '@' host name related text '>' |
For example: <20180306154822808383-5933b654b26c4495bb0b619ab72b3bc6@myservername>.
