I do not know you are using exim(3) or exim4, but both comes with ample

I am not in a mood to analyse your situation (late night...), but I
recommends you to reads "man 8 exim4" if you are using exim4.
Especially options starting with -b something such as -brw, -bf, -bF,
-bV, ... may be of your interest.

I know exim is too flexible ....

Good luck.
