Found a good method for tracking down this type of issue with someone else, run
Exim with debug option you will find a wealth of info. As shown in section
4.15 of Exim 4.10 spec document, basically doing test delivery with debuggin on

Try this :
* from terminal window go to Exim bin directory of box in question, type

# ./exim -v -d postmaster@???

you will get a lot of output on the screen, just wait till it stops then type

From: postmaster@???      (or any valid working mail account)
Subject: Test


then type [Enter] key, you will get another bunch of output, then type short
text like...

This is a test

then [Enter] key again then

^D

then

[Enter]

the email will then be processed by Exim and you will have a very detailed
output for analysis which hopefully will put you on track to finding cause of
problem.
