Not necessarily; that depends on how thorough the list server is. A substantial fraction
of this sort of criminal email has forged sender addresses. I occasionally get bounce
messages sent to me in response to forgeries that clearly (from their forwarding headers)
did not originate on my system, or even in my country.
I just looked at the headers of the offending message: it certainly looks like a forged
source address. It is not entirely clear which of the forwarding headers are real, but
possibly an ISP in Sweden is part of the path. Open relay somewhere?
