That means the original recipient address (a@example.org) was not found 
(unknown or expanded to the root account) and Exim tried to deliver the 
message to the postmaster (root@example.org) which also failed. This 
usually comes from a bad configuration of the MTA (mixed/unconfigured 
local/remote setup).

Look at the dates, those are old entries.

The test message you sent yesterday was on "Tue, 12 Jun 2012 21:31:19" so 
you have to look for Exim4 logs matching that date/time.
