Slight wrinkle in my diabolical plan:
Yahoo only marks bulk mail when it is forwarding it. BIS checks it as a POP address, before the [bulk] prefix is placed.
But I can simply have my mail autoforwarded to my BlackBerry as I was, vibrating whenever something comes to
And also gather Yahoo mail as POP with no notification, so that the unfiltered mail is there for review if needed.
Thanks again.
