Bug#990344: exim 4.94.2 update default configuration option breaks MTA

Hello:

Please excuse me, it happens that english is not my native language 
so it is quite probable that I may not have expressed myself 
correctly.

> Overwriting local customizations is not an option.

I was referring to whatever files are installed by *default* by the 
exim-config package.

As I understand it, these files are *not* local customizations.

Of these files, the one probably used my most desktop installations 
is the /etc/exim4/exim4.conf.template file used for the basic 
non-split configuration.

Using an exim4.conf.template file from any version prior to exim 
4.94.2 *will* break exim 4.94.2. 

Now, when I upgraded to exim 4.94.2 the installer asked me to make a 
choice with respect to the configuration.

I chose the *default* (recommended) option. ie: to keep the existing 
configuration.

But this *existing configuration* included the default 
exim4.conf.template file from the previous version of exim4.

Making that choice (recommended) resulted in the installer keeping 
back the updated exim-config 4.94.2 package and leaving the installed 
version in place.

Leaving the installed version in place broke the exim 4.94.2. 

Thanks in advance,
