Note the change between this message's header and that of the
previous message you sent. Instead of the hub machine adding
Message-ID: header, the local machine added that
header. You can tell because the local machine's name
appears there instead of the hub's name.
Date: header was also added locally, but
there is nothing to indicate that fact.
Date: header should be added locally
to accurately reflect the posting date of the message. If
you didn't supply a
Date: header, instead allowing the
hub to supply it, and the hub were down for
a while, that header would be inaccurate by the
amount of time the hub was down.
