I have no D or H files in my /var/spool/mail/exim/db directory.  The is 
a file (20kb) called retry.  It is a Berkeley DB (Hash, version 5, native 
byte-order) file, which I don't know how to 'view'.

Ahhh.   I just found the D and H files under /var/spool/mail/exim/input.
I suppose before I go too far into this I'm gonna do some reading to see
what these different directories are for.  Thanks for the Clues, Tim.
