Although they are not anonymous remailers, mail-to-news (mail2news or
M2N) gateways are an important part of the remailer network.  They
forward email messages to Usenet, permitting posting of messages or
(in some cases) binaries to certain newsgroups.  (See FAQ 4.8 for
instructions on determining which newsgroups are available.)

Be warned that these gateways by themselves do not make messages
anonymous.  Their administrators *will* keep logs.  It is the
remailers that strip off the identifying information from your
message, *not* the M2N gateway.  The gateway only delivers to a
newsgroup.  See the official help file M2N gateways by sending a blank
email to <mail2news@anon.lcs.mit.edu> with the subject "help" (no
quotes).  It is when you use an anonymous remailer in combination with
a mail-to-news gateway that anonymous newsgroup posts are possible.

There are actually two methods of posting anonymously to Usenet: via
an "Anon-Post-To:" directive or via an "Anon-To:" directive.  Note
that in most cases remailers with "post" in their cap strings actually
forward to a M2N gateway rather than posting via NNTP, so these
methods are often equivalent.

Method #1
Below is a template for the first method.  Send the following email
message to a remailer that supports anonymous newsgroup posting
("post" in the cap string).

::
Anon-Post-To: misc.test

##
Subject: This is a boring test 

Start your message here.

Method #2
Below is a template for the second method.  Send the following email
message to a Cypherpunk remailer ("cpunk" in the cap string).

::
Anon-To: mail2news@dizum.com (or any other mail2news gateway)

##
Subject: Is Gretchen Down?
Newsgroups: alt.privacy.anon-server
X-No-Archive: yes (this line is optional) 

Start your message here.

Both of these methods will work.  Pay attention to the cap strings.
Many remailers are PGP-only ('pgponly" in the cap strings). So before
sending to those remailers you will have to encrypt the above with the
remailer's pgp key.

Here are some other mail2news gateways you can use: 

	<mail2news@anon.lcs.mit.edu> *
	<mail2news_nospam@anon.lcs.mit.edu>
	<mail2news@dizum.com>
	<mail2news_nospam@dizum.com>
	<mail2news@freedom.gmsociety.org>
	<mail2news_nospam@freedom.gmsociety.org>

See FAQ 4.8 for an explanation of the significance of the "nospam"
gateways.
*Note that <mail2news@nym.alias.net> is an alias for
<mail2news@anon.lcs.mit.edu>.  The preferred address is
<mail2news@anon.lcs.mit.edu>.

See this Web-Based Mail2News Interface <http://forward.to/mail2news>
for a quick-and-dirty way to post anon to Usenet. See also

mail2news gateway (formerly known as <mail2news@zedz.net>).
