my own in return

X-Spam-Status: No, score=-6.2 required=5.0 
tests=AWL,DKIM_SIGNED,DKIM_VALID,
	DKIM_VALID_AU,HEADER_FROM_DIFFERENT_DOMAINS,LOCAL_HASHWL_ALL,
	MAILING_LIST_MULTI,RCVD_IN_DNSWL_MED,RCVD_IN_HOSTKARMA_W,
	RCVD_IN_MSPIKE_H5,RCVD_IN_MSPIKE_WL,SPF_HELO_PASS,SPF_PASS,
	T_SCC_BODY_TEXT_LINE autolearn=ham autolearn_force=no

so it seems fuglu works

hope maillist users turn there dkim signers into sign only, not verify 
aswell, verify must only happen in dmarc
