Scott,
You are right to suggest that receivers don't know how to segregate MLM mail from the rest of the Internet. But with the TPA-Label approach, the mailing-list does not need to change the Author Domain. Using a single transaction, the TPA-Label scheme provides targeted domains a means to indicate whether their message might be carried by a third-party service, whether the service has been authorized, and how this service can be authenticated. In this way, only the code checking ADSP compliance needs to change, and not all the various mailing-lists and MUAs designed to inter-operate with their existing practices. -Doug _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
