NODE 4d9a2196Starting a remailer
I need info on what's needed to operate a secure remailer out of an edu
address.  I'd appreciate anything about software, installation, maintenance,
problems, etc... 

Thanks,
	Mo

If you are thinking of setting up a remailer on a general usage type
unix shell account, then first find out if the usage policy allows you
to run one (for example, remailer are forbidden here at Rice).
Actually, I would recommend asking first, to head off future
headaches, as I can think at least two other (former) remailers run at
.edu sites that were forced to close.

Other than that, try to find out if sendmail logs are kept, especially
if they are world readable (this will reduce the security of the
remailer, but you won't be able to anything about it anyway).

The software is easily available, installation isn't hard (you have to
install PGP as well).  Maintenance isn't much unless you expirement
around.  I would recommend blocking anonymous mail to whitehouse.gov
and other similar addresses.

I don't know about problems; I never had any, but these days it seems
more and more people are finding out about remailer, and with that
comes abusers.  John Perry had to shut down because of abuse, after
withstanding the RC4 posting crisis.  Be prepared for some hassles.

Actually, I would recommend finding a remailer-friendly site like
c2.org and setting up there.

Ah but if you *really* want to run out of an .edu address,
contact me about getting an alias in leri.edu.

NODE bb2655a2Re: Starting a remailer
I'm going to be along to set up a remailer shortly.

Two questions:

Since I've only limited bucks but have certain needs, can I get a
package deal on a remailer shell account and the MX service? What
I'd like is to have all mail to xxxx@myname.com to be forwarded to
my shell account no matter what xxxx is.  Preserving the xxxx, though.

Given the goal of limiting remailer liability, what about having
them be anonymous?  Instead of send you a check, send an unidentified
money order.  This would even allow ownership to change on a frequent
basis without the system owner knowing who the current operator is.

Thoughts?  Comments?  Offers to send cute girls?

Absolutely -- anonymity of the remailer _account holder_ is a central part of 
the "guerrilla remailer" concept AFA I'm concerned. Tim keeps reminding us 
that the distinction between the machine owner/ISP admin and the remailer
operator can be crucial, for legal reasons (i.e. the ECPA). I think it may
also be useful to push this distinction down a level, separating the _account
owner_ from the _remailer operator_. I get the feeling that in many cases the
folks willing/able to fund remailers aren't the same folks who are willing/
able to operate remailers. Hence it seems natural to have a collaboration 
between a remailer sponsor (person or group providing money to pay for an 
account or dedicated hardware) and a remailer operator (person or group 
providing time & technical skill to install, maintain, and upgrade the 
remailer). Of course the sponsor and operator could be anonymous from each
other, and I suppose even the members of each group need not know each 
others' identities.

c2.org allows anonymous account creation over the net, which is handy.
If you're feeling lucky, you could send cash in the mail instead of a money
order....

IMHO the tricky part is maintaining anonymity of the _operator_ over time. In
a reasonably general model, an operator will need to access a remailer
account across the net repeatedly, to recover from system crashes, install
new versions of remailer software, etc. The nature of a telnet session 
doesn't lend itself to reordering, latency, or cover traffic AFAI can see.
Perhaps the technique of sending encrypted shell scripts to an account for
execution (inquired about here recently) could do the work. Anon-HTTP
combined with WWW forms and some not-so-safe-TCL might offer more palatable
real-time responsiveness. I've experimented a little with a protocol for 
handling complaint mail, in which a cron job (or equivalent) running on the
remailer account greps the received non-remailing mail for complaint keywords,
then encrypts the result and chain-remails it to the operator (or posts it to
some well-propagated newsgroup).

Please cc: me on the latter.  Thanks. ;}

	If you are getting MX service forwarded to a local account
that will cost you only $5/month. So everything you want would cost
$15/month plus $40 startup for the domain.

	Yes, Community ConneXion accepts unidentified payment for
accounts.
