In practice, if I look at mail with yahoo.com author addresses for example, I find that with DKIM yahoo.com signatures, they're about a million times less likely to be forged than without those signatures. That's not to say that yahoo.com forbid forgery, but they may find that their mail stream reputation improves if they take measures to prevent forgery. -- 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
