That "somewhere" has been outdated for years. h_c_s is an exim 3
configuration option which has been migrated to exim4's ACLs.

I suspect that, yes.

It sometimes helps to read beyond what grep outputs, and it should be
clear that .ifdef CHECK_DATA_VERIFY_HEADER_SYNTAX enables some checks
which will deny with a message called "Message headers fail syntax
check" on some condition.
Unfortunately, one needs context information about your configuration
to tell you where to activate that macro, and since this question is
asked so often, it is explained quite verbosely in README.Debian.gz.

The book by Philip Hazel is a good tutorial, but you would need to buy
it. The spec.txt file is a good reference, but admittedly hard reading.
Maybe it's a good idea to start reading spec.txt chapters 1, 2, 3 and
6 to get a rough impression of how exim works, and then to work
yourself through our configuration file, looking up the meaning of the
options that we actually use.

The default configuration is rather verbosely commented, but the
comments expect some basic understanding of exim's concepts.
