* Simson Garfinkel:
Actually, message-id's frequently have internal meaning, depending on where they are issued. If Apple just wanted a random 128-bit number, they wouldn't put the dashes in it. There is internal structure --- a 32-bit number, three 16-bit numbers, and a 48-bit number.
That's just the format used by UUIDs. Some ways for generating such IDs are described in RFC 4122.
