I would think so myself, but I'm old fashioned.. Ubuntu does not install
one by default, and the typical desktop environment works just fine without

Try removing exim and see what packages it complains will also have to

The package you installed that required local mail delivery probably had
exim4 as it's first choice.  Exim is the default in Debian, so that
