I've looked for him before and didn't find him. It turns out that
his address was an old hummingbird.com address.
I don't believe those return messages are coming from the list--they
do not have the list footer on them. Many of these type of messages
(including out of office messages) are sent directly to the poster of
a message and I have no control over that.
His hummingbird.com address has been removed. Please feel free to
send any messages you get like this to me and I'll see what I can do.
