   VERSION 3.99/SR40 - DECEMBER 6 2018   
   -----------------------------------   
      
   NOTE: The structure of the Echomail database file DBRIDGE.ADF has changed.   
         If you are a developer or advanced user, refer to TECHSPEC.TXT.   
      
   This minor release adds two new options; Circular Path Detection (CPD)   
   and bad AREA kludge checking. It also upgrades the Windows version of BinkD   
   to 1.1a/99.   
      
   In CONFIG-ECHO AREAS, there is now a new question if you wish to have CPD   
   functionality enabled for the Echomail area. This is an advanced feature   
   that will likely only be used by mail-Hub systems.   
      
   If you answer YES to this question, during the Unpack/Toss cycle, D'Bridge   
   will examine every message received in this area for duplication in the   
   PATH kludge-line. The PATH (and SEEN-BY) kludges are very important when it   
   comes to Echomail. Without them, it would be difficult to trace or   
   troubleshoot problems when a message "echoes" its way across the network.   
      
   The PATH kludge is simular in concept to the VIA kludge for Netmail; in   
   that as a message "travels" through the network, the system(s) that process   
   the message add themselves to the PATH. The PATH kludge is "two dimensional"   
   meaning that only the NET and NODE of the address is added. When a system   
   adds itself; the NET portion changes only if necessary. Duplication occurs   
   when either a Sysop or software strips the SEEN-BY's or manipulates the   
   PATH in a way that a system is added twice.   
      
   NOTE: It is impossible for a properly configured D'Bridge system to ever be   
         the cause of a circular PATH; no matter the version or edition.   
      
   An Echomail message received with a circular path will be tossed to the   
   BADECHO area for your inspection. Note that only the applicable address is   
   checked during CPD; not all of your addresses. For example, if you have an   
   alias-address defined for the area, then CPD will only check based on that   
   address. If no alias address is defined, then the CPD applies to your   
   primary address. CPD cannot be used for Point-addresses.   
      
   By default, CPD is disabled. Do not enable CPD unless you are specifically   
   receiving duplicate messages in the area that are not being caught by   
   the built-in duplicate message checking.   
      
   The "Bad AREA kludge" option in CONFIG-PACKET/MAIL CONTROL forces D'Bridge   
   to examine every received message for the correct "placement" of the AREA   
   kludge. The AREA kludge defines a message as Echomail. Sometimes, for   
   whatever the reasons, a "grunged" message will have this in other places.   
   When D'Bridge encounters a grunged message, it will be moved to the   
   BADECHO area for your inspeection. Answer YES for this checking or NO if   
   not. The default setting is NO.
