It is supposed[1] to reprompt (because the questions are unseen) but with
the correct answers preselected, as debconf-db is preseeded with the
values in /etc/:
if [ -e /etc/exim4/update-exim4.conf.conf ] ; then
        . /etc/exim4/update-exim4.conf.conf || true
        # set defaults using these values
... and the postinst-script saves the debconf data to /etc/e/u-e.c.c

This is basically copied from the debconf-devel manpage.

[1] I am using "supposed" because I have not actually tried what
happens if /var/cache/debconf/config.dat is deleted.
