It seems to me that the best application of DKIM here would be to ensure that posters to closed lists are (likely to be) who they say they are. For example, a user could assert that all their posts will be signed, or a list manager could assert that only signed emails will be accepted from certain domains. I manage a list server that is frequently spammed. Not much of the spam gets through, but occasionally a spammer gets lucky and picks a sender address that gets through. -- Ian Eiloart IT Services, University of Sussex 01273-873148 x3148 For new support requests, see http://www.sussex.ac.uk/its/help/ _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
