   In the case of the article ID it has to be more than that, since the article ID   
   needs to be able to consistantly resolve to a message.  A date written and name   
   would be too vague.  Sometimes when messages are processed in batch it'll be   
   possible for two messages to have the same datestamp from the same person.   
      
   Mystic uses a unique identifier and some hash values along with the primary key   
   of the message base to generate the article ID.  This way it can figure out the   
   base and then more quickly perform a lookup using the hash first to limit the   
   result set (before loading the full message to check the MSGID for a match).   
      
   The NNTP server can create MSGID on the fly if they are missing so it will   
   always generate an article ID (which I have enabled now).  My concern with   
   doing that was there will be added risk of message base corruption if the NNTP   
   server needs to do massive updates to generate unique IDs at the same time   
   something like message tossing is happening.   
      
   In order to reduce the amount of times the NNTP server needs to generate MSGIDs   
   I went back and changed things (in the next build) so that Mystic will always   
   generate MSGID even if its a local, newsgroup, or QWK networked base...   
      
   The only remaining thing would be to add MSGID on the fly when tossing messages   
   from QWK and Fido networks.  I've added it into QWK tossing now too but for   
   Fido I am a little hesistant to do so.  Technically adding a missing MSGID   
   would be changing message content and anytime Mystic's tosser has the option to   
   do that there is a subset of Fido people who have huge meltdowns over it.
