IME Exim's code is architecturally straight-forward. Philip doesn't go in
for multiple layers of abstraction, and most of Exim's abstractions
(lookups, expansions, etc.) are exposed to the user. Another example is
the fact that configuration options have a very simple correspondence to
variables in the code, usually one-to-one. Most of the complexity comes
from all the details of configuration options and built-in know-how, which
leads to bredth rather than depth.
