| I have downloaded your remailer-conf file and I have a few questions
for you.
Under the heading GENERAL it says "From Header Allowed: On all messages
and posts; name and address" yet in the commented section under the
heading ANON-POST-TO - BLOCKED NEWSGROUPS you state "if anybody wants
to post to a group that is blocked, or has a disclaimer, or is one in
which full 'from' headers are not allowed, then do the following:"
How can there be groups that you will not allow a full from header when
"From Headers are allowed on all messages and posts; name and address"?
Other Reliable remailers have under the heading GENERAL "Messages
Received Last Week" but you don't. Is there a reason for this omission?
Also under the heading GENERAL you have "Maximum Message Size: 80000
bytes" yet others have "Maximum Message Size: 1024000 bytes". Why such
a small Maximum Message Size?
Why don't you show "Admin Contact" under the heading of GENERAL as do
the others?
Under the heading FEATURES it says "Random CPunk Latency Maximum:
01:01". What is the reason for the extra minute? Why not just 01:00?
You have "Dummy Traffic Generation: False". From what I have read,
Dummy Traffic Generation is one of the features of Reliable and
Mixmaster that assists in thwarting traffic analysis. In light of your
suggestions in a.p.a-s recently, regarding "Normalising" and
Partitioning Prevention", I would have thought you would have Dummy
Traffic Generation set to "True". Why don't you?
Thanks in advance for addressing my questions.

More or les the same message was in both sections, and the bit about
'from' headers was badly phrased. Both sections now have the same
message. Custom 'from' headers are not allowed on newsgroups that
have a disclaimer; otherwise, they are allowed.

No. I'll turn it on.

The remailer discourages binaries. For text messages 80k is plenty,
don't you think?

Added.

I think it's a bug in Reliable. the latency goes from 1 minute to 10
minutes.

Agreed! 80kB is not small at all! Besides, it only matters for the exit
hop (with Mixmaster traffic anyways).

Just because someone alows 1MB, doesn't mean everyone else has
to. There are other remailers that allow a similar amount to
Parsifal.

Makes no difference in reality. Don't worry about it.

He should. I hope he corrects this.

80k is pretty small when taking into account size increase due to multiple
encryption layers... that means that system would not make a good candidate
for first hop or early in the chain. and of course, NEVER use it for an
exit.. you'll get read or edited.

Just to prove you wrong, I wrote a little batchfile that would encrypt
to my own PGP key using ascii-armor as needed by CPunk traffic and here
are the resulting sizes of the message I am replying to here (including
all headers like the Path one):
2.174
1.937
2.349
2.777
3.223
3.697
4.193
4.709
5.249
5.813
6.399
7.013
7.653
8.321
9.023
9.803
10.615
11.453
12.331
13.231
14.171
15.145
16.147
17.215
18.317
19.509
20.755
22.053
23.395
24.805
26.265
27.829
29.449
31.133
32.899
That would be 36 hops, just how many hops where you planning to use for
your message? Note that it is still nowhere near the 80kb limit here.
And know that JBN2 will probably warn you for messages bigger than the
klen of a cypherpunk remailer! And know that your argument doesn't apply
to the preferred mix traffic (except for the last hop). Also know that
PGP does in fact compress text messages greatly, still reducing your size.
If you want to verify these results yourself, here is the (crude) batch
file I used to generate these stats:
/////
@echo off
del result.txt
del x.asc
:loop
dir x.>>result.txt
pgp -eat x thomas
del x.
ren x.asc x
goto loop
/////
Note that it will never finish and you can use 'sort' on the file
'result.txt' that you will get.
Sorry to proof you wrong,
Thomas
