All CUBE messages will conform to certain standards with respect to message headers and format; thus, recipients will be able to identify, and, if they wish, filter CUBE messages.
The "Subject:" header will start with the string "[CUBE]".
Each message body will start with a "fronter", that is, boilerplate text identifying the approving authority for the message. The text will look roughly like this:
The following message has been approved for distribution by
Person Name <email@example.com>, Title of Office/Dept.
An extra header "X-URL:" will be used, and will point to the CUBE web pages.
