The easy/dirty way to start fresh, without needing to temprarily
install postfix:
apt-get --purge install exim4
/etc/init.d/exim4 stop
dpkg --force-depends --purge exim4-config
dpkg -i /var/cache/apt/archives/exim4-config_4.69-9_all.deb

This is probably not what you want. The main thing you'll need to is 
take (a copy of) /etc/exim4/exim4.conf.template.dpkg-dist, re-apply the
local modifications present in /etc/exim4/exim4.conf.template and
install this modified file in /etc/exim4/exim4.conf.template. If this
is not enough repat for tghe other files with .dpkg-new files.
