E-mail indexing doesn't work in Intrepid because the old indexer module doesn't work with the version of Evolution in Intrepid. There is a new push-module to replace the old indexer module which should work with the newer versions of Evolution, however, that is not working properly yet and has been disabled too. There is already a bug report tracking that, so I'm marking this a duplicate of that one.
