-LMDB Lookup support
--------------------
-LMDB is an ultra-fast, ultra-compact, crash-proof key-value embedded data store.
-It is modeled loosely on the BerkeleyDB API. You should read about the feature
-set as well as operation modes at https://symas.com/products/lightning-memory-mapped-database/
-
-LMDB single key lookup support is provided by linking to the LMDB C library.
-The current implementation does not support writing to the LMDB database.
-
-Visit https://github.com/LMDB/lmdb to download the library or find it in your
-operating systems package repository.
-
-If building from source, this description assumes that headers will be in
-/usr/local/include, and that the libraries are in /usr/local/lib.
-
-1. In order to build exim with LMDB lookup support add or uncomment
-
-EXPERIMENTAL_LMDB=yes
-
-to your Local/Makefile. (Re-)build/install exim. exim -d should show
-Experimental_LMDB in the line "Support for:".
-
-EXPERIMENTAL_LMDB=yes
-LDFLAGS += -llmdb
-# CFLAGS += -I/usr/local/include
-# LDFLAGS += -L/usr/local/lib
-
-The first line sets the feature to include the correct code, and
-the second line says to link the LMDB libraries into the
-exim binary. The commented out lines should be uncommented if you
-built LMDB from source and installed in the default location.
-Adjust the paths if you installed them elsewhere, but you do not
-need to uncomment them if an rpm (or you) installed them in the
-package controlled locations (/usr/include and /usr/lib).
-
-2. Create your LMDB files, you can use the mdb_load utility which is
-part of the LMDB distribution our your favourite language bindings.
-
-3. Add the single key lookups to your exim.conf file, example lookups
-are below.
-
-${lookup{$sender_address_domain}lmdb{/var/lib/baruwa/data/db/relaydomains.mdb}{$value}}
-${lookup{$sender_address_domain}lmdb{/var/lib/baruwa/data/db/relaydomains.mdb}{$value}fail}
-${lookup{$sender_address_domain}lmdb{/var/lib/baruwa/data/db/relaydomains.mdb}}
