From: "Alexey I. Froloff" <ra...@raorn.name> Add support for indexing and searching the message's List-Id header. This is useful when matching all the messages belonging to a particular mailing list.
Rework of the patch by Pablo Oliveira <pablo at sifflez.org> Differences from original patch: The whole list ID indexed as boolean term, not split by words. List description is not indexed at all.
