Then I read further and found "To participate in the program, senders must sign their outbound emails with DomainKeys (DKIM is not currently supported)."
This is the second time in recent weeks that some large mail service has used it's 600 lb. gorilla status to try to coerce me into something, and I don't like it.
C'mon, Mark, you know that the only problem here is that there's no accepted standard; they have to authenticate "you" somehow (do you really want me to be able to spoof you and get information about your mail to Yahoo customers?), and the right "you" to authenticate is the apparent source of allegedly objectionable mail. So it's going to be SPF or DomainKeys or something like that.
But you've identified the problem correctly (in more ways than one). 600lb gorillas don't move very fast most of the time, but once they do get in motion they're terrifying.
Sorry to say, I don't think there's much chance the gorillas are going to slim down, either. There are too many advantages to being big in this industry.
