All messages live in a database on the Andrew File System.  The only program 
that actually accesses that database is called the \italic{messageserver}; all 
of the user interface programs, such as Messages, access messages by remote 
procedure calls to the messageserver program.  Animating the drawing below 
will show you how mail is sent through this path.
