IMHO, there is a very good way to complain about spams. Although many
return addresses are faked, examining the headers of the spam usually
points to the correct location to complain to. Also, the spam should be
primarily directed to the postmaster rather than the spammer. For more
information, one can check out the alt.spam FAQ on the WWW and the group
news.admin.net-abuse.misc, where spam is discussed.
