This being a few months ago now, I presume that you actually went ahead 
with the change.  Indeed, log messages from Exim4 seem to indicate that 
it tries to open DB files as in either DB3 or DB4 format.

However, it still does not read the DB4 files that were written by 
"DRAC".  An example:

     # exim4 -bhc 192.168.11.3
     ...
     LOG: Berkeley DB error: /var/lib/drac/dracd.db: unsupported btree 
version: 9
     LOG: failed to open /var/lib/drac/dracd.db as a db (v3/4) file: 
Success

     # exim4 -bV
     Exim version 4.34 #1 built 11-Sep-2004 12:28:23
     ...


Looking at the contents of the DB itself:

     # db4.2_dump -p /var/lib/drac/dracd.db
     VERSION=3
     format=print
     type=btree
     db_pagesize=512
     HEADER=END
       192.168.11.2
       1098919386
       192.168.11.3
       1098920536
     DATA=END


That said, on a side note, I am also a little confused by the 
"VERSION=3" header in the DB itself, because the "db3_dump" command 
does not work on this file.  It prints the same message:

     # db3_dump -p /var/lib/drac/dracd.db
     db_dump: /var/lib/drac/dracd.db: unsupported btree version: 9
     db_dump: open: /var/lib/drac/dracd.db: Invalid argument
