This mail message contains a POINTER (reference) to data that is not
included in the message itself.  Rather, the data can be retrieved by
sending a special mail message to a mail server on the network.
However, doing this automatically is slightly dangerous, because
someone might be using this mechanism to cause YOU to send obnoxious
mail.  For that reason, the mail message that WOULD be sent is being
shown to you first for your approval.

This is the message that will be sent if you choose to go ahead and
retrieve the external data:

Subject: Automated Mail Server Request
