This is very interesting. For our antispam system I'd like to be able to distinguish between mailing list traffic and person to person traffic, since they largely have very different characteristics. In this sense, to me, 'do the right thing' would be to re-sign the message -- we've been able to use Yahoo! Groups (re)signing as a feature. I'm sure that others could easily argue that doing the right thing is to leave the message in a way that encourage the final receiving system to check the initial signature, so they could apply rules based on the original author. miles _______________________________________________ ietf-dkim mailing list http://dkim.org
