If I strip down your update-exim4.conf.conf file to the non-comment
lines
-------------
dc_eximconfig_configtype='smarthost'
dc_other_hostnames='corinnis.guefz.de'
dc_local_interfaces='127.0.0.1;192.168.1.3'
dc_readhost=''
dc_relay_domains=''
dc_minimaldns='false'
dc_relay_nets='192.168.1.0/24'
dc_smarthost='smtp.netcologne.de'
CFILEMODE='644'
dc_use_split_config='true'
dc_hide_mailname='false'
dc_mailname_in_oh='true'
dc_localdelivery='mail_spool'
-------------
and install it locally then "dpkg-reconfigure -plow exim4-config" works
as expected. :-(
