Please not now...:-)

Exim4 debconf screens are translated to 36 languages and are involved
in Debian Installer process. Changing the wording of the templates
would fuzzy all these translation, and getting them back up-to-date
would be a real huge task.

This may sound minor but would be a real frustration to all
translators who work hard for keeping their translation ratio to 100%
for d-i involved packages.
