There is a person who keep sending anonymous messages to
soc.culture.china. He/she sometimes uses a fake name and
sometimes uses someone else's real name which causes
great confusion. Once there were two messages and each of
them claimed that the other were forged.

Now I guess this person could use sendmail to forge a
message.

Is there any methods to prevent messages from being forged?
