I think it's more likely that someone on the list has a forwarder set up
that forwards to peter whalley uol com br  Unfortunately the dumb
challenge/response system (I guess the "dumb" is redundant there
actually) doesn't show the full headers of the mail it's responding to
so it's not possible to tell who the actual subscriber is.

Anyone wanting to do a real denial of service attack could do much
better than this.
