The MailEntityProcessor is an "extra" and does not come normally with the DataImportHandler. The wiki page should mention this.
In the Solr distribution it should be in the dist/ directory as dist/apache-solr-dataimporthandler-extras-1.4.jar. The class it wants is in this jar . (Do 'unzip -l jar' to find the classes inside a jar.) You have to make a lib/ directory in the Solr core you are using, and copy this jar into there.
