That's certainly been mentioned a lot of times and is certainly consistent with what p=reject says it means. The problem is pragmatic: there are a lot of people who use Yahoo's mail, very few of them understand the technology very well, and they'd see this as just another baffling thing that happens on their computers. I would like to encourage all of the Yahoo users on my lists to find a better provider, but that will take years. In the meantime, the church has a lot of meetings to organize. It's a market power problem, not a technical problem. R's, John
