With all the anti-spam laws starting to either show up or be discussed
by various government bodies, it would seem that a law needs to be added
that says commercial advertisement is deemed spam if such tricks are
used. I keep seeing more in the headers that starts at
dns2.kokushikan.ac.jp, and appears to attempt being hidden this way. The
reply-to addresses are always to some free email account at excite.com,
or yahoo, or hotmail, etc, such that all they need to do is get a new
reply address for free the moment one gets banned for spam (and I report
all of them; yahoo and others usually reply to tell me the account has
indeed been banned). The free email places need a way to block spam
domains like dns2.kokushikan.ac.jp, but I doubt they have sufficient
interest, and too many objections to doing so.
