You also have a Debian Exim configuration, which is so very different
from normal (with good reason!) that the folks on exim-users don't
normally help with it:
http://pkg-exim4.alioth.debian.org/
That has pointers to Debian-specific information, including a
Debian-specific Exim mailing-list.
A friend's Debian machine has: /usr/share/doc/exim4/README.Debian.gz
Note that everything in your configuration is Debian-specific. Not one
line of it looks like general Exim config. Sorry.

The relevant Exim rewrite rule needs the 'T' flag; see:
31.8 Flags specifying which headers and envelope addresses to rewrite
in The Exim Specification; Debian provide this as the file:
/usr/share/doc/exim4/spec.txt.gz

All of your config file is made up of Debian-specific hooks. Whilst
someone on the exim-users list might be able to help, you'll probably
get a faster and better response from the Debian-specific mailing-list:
http://lists.alioth.debian.org/mailman/listinfo/pkg-exim4-users
It looks as though the unclean quick hack to get it working would be to
edit /etc/exim4/conf.d/rewrite/31_exim4-config_rewriting to add the 'T'
flag to the 'Ffrs' set and do whatever it is Debian needs to rebuild the
config. That looks like the sort of change that will break with the
next update though.
You might be able to copy the relevant line into another config file in
that directory, replacing 'Ffrs' with 'T'. Pass.
Ask some Debian folk on pkg-exim4-users how to fix it properly.
