Which remailers like to handle anon mail?

[johns@macadam.mpce.mq.edu.au (John Savage)]

I have been trying to form a picture of the anonymous remailer services 
available to subscribers to USENET newsgroups.

Here is the current list of mail-to-news gateways (obtained by executing
finger remailer.list@chaos.bsu.edu):

alt.test.usenet@decwrl.dec.com    / yes, works for me
alt.test@news.demon.co.uk         /  "     "
alt.test@news.cs.indiana.edu      /  "     "

alt-test@pws.bull.com             X host unknown
alt-test@ucbvax.berkeley.edu
alt-test@cs.utexas.edu            / works; discourages anon mail

also, soda.berkeley.edu           /works well


I would appreciate a few details, if anyone can assist, please:

Is pws.bull.com no longer in existence?, as I get "unknown host".

Is this a list of all the public gateways that exist in the whole world???

Which of these sites welcomes anon mail for anon posting?  Anyone know?
(apart from soda)

To cross-post to 2 newsgroups, I believe the standard method is:
mail alt-test@cs.utexas.edu
CC: misc-test@cs.utexas.edu

So, can I cross post to a 3rd group by using BCC: misc-misc@cs.utexas.edu?
And, does this mean that 3 groups is the upper limit for cross-posting?
(I know soda has no upper limit, but I'm asking about the others.)

There are plenty of Cypherpunks anonymous remailers available for the
net to use, but it seems to me that they satisfy only one-half of the
requirement -- we also need a number of obliging mail-to-news gateways if 
anonymous news is going to be a solid proposition.

Awaiting your answers with great interest!
