Quite possible, though not via spoofing (forged email headers). The real
address seems to be 211.206.215.136. I'm trying to become a bit more
fluent in the means of verifying headers and tracing real sources of
forged headers. I know the 211.206.215.136 is correct, the origio.net
address is the return address, which apparently does not exist. I do
know that a series of these spams are advertising Korean sites and have
.kr domains, plus a few others in asia.
