This function returns the Unique Identifier of the current email as provided by the mail server. Depending on the mail server, this Identifier could be unique on a global scale, a server scale, or an account scale. Sometimes, this value is the same as the Message-ID header in the email. Whatever the case, the value should be Unique for the Account you are connected to. If you later connect to the same Account again, you should never find an email with an Identifier of a previous email you downloaded from that Account. If you do not delete an email from the server, you can later get back to this same email by sending this Unique Identifier to the POP3it_Adv_GoToMessage function.
