Message-ID
From Wikipedia, the free encyclopedia
Message-ID is a unique identifier for a digital message, most commonly a globally unique identifier used in email and Usenet newsgroups.[1]
Message-IDs are required to have a specific format which is a subset of an email address[2] (though Microsoft Outlook is known to generate invalid IDs with three parts[3]) and to be globally unique. That is, no two different messages must ever have the same Message-ID. A common technique used by many message systems is to use a time and date stamp along with the local host's domain name, e.g., 950124.162336@example.com.[4]
