Subject: [exim-dev] [PATCH] dynamically loadable lookup modules
This patch, originally written by Tim Jackson, adopted/fixed by me
and recently forward-ported/updated by David Woodhouse, makes exim
able to (optionally) dynamically load lookup modules rather than
requiring them to all be built in.

This can be used by distributors to avoid shipping O(N^2) packages
for N different database libs or linking one exim binary against
all possible database libraries by providing a package for each
lookup module that isn't built-in or similar packaging.
