Input Queue:  Needs to exist, end with \ and not be used for anything else.  
              This is where incoming SMTP traffic is cached as it is received.
Ouput Queue:  Needs to exist, end with \ 
              This is where we move the e-mail after we have completely received it.
Listen Port:  This should always be 25.  Only change this if you are trying to get
              around issues where port 25 is blocked -- no other SMTP server will
              be able to access your SMTP server if this is not port 25.
PC Name:      What do we call ourself when others connect to us?  If not specified
              we use the PC NET (Found under Windows Network settings.)
Extension:    Input Queue names files with a .txt extension by default.  When the
              file is moved to Output Queue, the extension changes to this.  
              THIS FEATURE IS NOT YET ACTIVE.
