There are two points here that don't scale to me: 1) I don't think putting a burden on the users to register every list to which they might want to subscribe, or become subscribed, is scalable. They will forget, or do it wrong, or lists will relocate to different domains, or a host of other scenarios, and then mail will start bouncing and complaints will fly. 2) I don't think that a large organization with security-focused operations people will think kindly of the idea of user-generated data making its way into the DNS, whether that's an automated process or not. That doesn't even touch on the issue that user-generated data is being used to publish some kind of authorization of the use of that domain by others. _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
