12. How do I send fakemail? 

Telnet to port 25 of the machine you want the
mail to appear to originate from. Enter your message as in this example:

 HELO bellcore.com
 MAIL FROM:Voyager@bellcore.com
 RCPT TO:president@whitehouse.gov
 DATA

        Please discontinue your silly Clipper initiative.
 .
 QUIT

On systems that have RFC 931 implemented, spoofing your "MAIL FROM:" line
will not work. Test by sending yourself fakemail first.
For more information read RFC 822 "Standard for the format of ARPA Internet
text messages."

13. How do I fake posts to UseNet?

Use inews to post. Give inews the following lines:

 From:
 Newsgroups:
 Subject:
 Message-ID:
 Date:
 Organization:

For a moderated newsgroup, inews will also require this line:

 Approved:

Then add your post and terminate with .
Example:

 From: Eric S. Real
 Newsgroups: alt.hackers
 Subject: Pathetic bunch of wannabe losers
 Message-ID:
 Date: Fri, 13 Aug 1994 12:15:03
 Organization: Moral Majority

 A pathetic bunch of wannabe losers is what most of you are, with no
 right to steal the honorable title of `hacker' to puff up your silly
 adolescent egos. Get stuffed, get lost, and go to jail.

                                                                Eric S. Real

 ^D

Note that many systems will append an Originator: line to your message
header, effectively revealing the account from which the message was
posted.
