Not that somebody is *deliberately* forwarding it to him.
My subscription is to "sentience@pobox.com" which automatically forwards to
"eliezer@tezcat.com". If tezcat started having problems, you'd get errors
from an address that bears no relation whatsoever to that subscribed. Pobox's
forwarding does *not* change it into a private email.
I hypothesize that something similar is occurring with Adrian.
The returned email will contain the address that is automatically forwarding.
We can then send an "unsubscribe whoever" command.
I'll try to be more clear, next time.
