 [ ]  New incoming mail packets will be backed up      
      immediately after being processed. Mail packet   
      backups will be stored in a sub-directory of the 
      SPOOL directory for each respective Server.      
                                                       
      Here's a typical example:

      NOTE:                                            
      Backups will be deleted at the next Netcall to   
      each respective Server, providing new mail       
      arrives. If no new mail arrives, existing        
      backups for each respective Server will be       
      retained.                                        
                                                       
      If, for some reason, a sub-directory doesn't     
      exist for a respective Server, mail packets will 
      be backed up with an extension of .BAK directly  
      in the SPOOL directory. This does not apply to   
      Fido mail packets(*.pkt), which will remain      
      directly in the SPOOL directory. However, this   
      scenario should never arise :-)
