[GreenKeys] Sorry for the duplicate post

[bill at horne.net]

I apologize for yesterday's duplicate post. I had a problem with my
email setup, and I didn't realize that the first attempt had been
"queued" for delivery instead of being deleted by the email software.

The post shows an invalid address: bill at billhorne dot homelinux dot
org, which was the "envelope" sender for the email. My actual address
is bill at horne dot net, so I'm very puzzled by how Mailman accepted
the post based on the "From" address, but displayed the "Envelope"
address (at least in the Digest version).

Bill, W1AC
