That line does not exist in Exim 4's default configuration. You must
have an Exim 3 configuration file.

Yes.

I do seem not to have listed it explicitly in doc/Exim4.upgrade, but I
do say in there that the concept of local domains is entirely abolished.

The Exim 4 book describes Exim 4. It does not describe changes from Exim
3. That would just confuse new users. The changes are described in
doc/Exim4.upgrade in the distribution.

It had to be removed. Exim 4 has no built-in concept of local domains.
Therefore, it was meaningless.

Why not look at the Exim 4 default configuration file?

Why not look at the Exim 4 default configuration file? A grep for
"literal" will get you to the right place.
