          Message-ID is usually generated by mail the client which composed the message. If it didn't, the mail server may do this then (although some servers do not do this and thus it's possible Message-ID will be missing). You should not rely on Message-IDs to identify messages. Also, if the same message was sent twice, both copies may have the same Message-IDs.

 To uniquely identify a message in the mailbox, it's better to use Unique-IDs. They are always generated by the mail server and always unique (as their name states).
