They posted in a previous thread about this, saying they couldn't
unsubscribe under their address, ie. somebody is relaying mail to
them. They were told they need to provide headers so postmaster can
determine what address is subscribed. They never replied (at least on
list). I'm not an expert about such things but I think without their
cooperation there's no real way to tell who the relay is.
