exim always uses a monolithic configuration file (with the exception of
includes). But Debian (and hence ubuntu) packaging is somewhat different
and their configuration scheme is very specific, so you should ask this
on debian/ubuntu exim lists. Perhaps you should have a look at
http://wiki.debian.org/PkgExim4
However, the posts you read about putting a transport_filter are
correct, so really, debian lists will help you better in placing your
snippet at the appropriate place.
All those things apart, a MTA should not modify the contents of a
message in transit, ever...
