During a package update, no information is ever lost. If you decide
to keep your configuration, the new configuration is unpacked and
saved with a .dpkg-dist extension. In this case, you'll probably have
a non-working exim because your old configuration may not fit the new

If you decide to take our new configuration, your old configuration
gets renamed to a .dpkg-old extension. In this case, you'll definetely
have your manual changes temporarily disabled.

In both cases, you'd probably go ahead with comparing new and old
configuration, and decide whether a change was yours or ours, and
apply your changes to our new configuration, which will most probably
yield a working configuration. This process is considerably easier if
you knew what you were doing instead of blindly following some HOWTO
document from the web.

Since the script with tries to identify old configuration snippets is
rather paranoid, you would probably have to manually move away the
.dpkg-old/.dpkg-dist files.
