 Glad to hear you didn't mind, Daniel.

Actually, I've enjoyed it! :)
It was very crazy to see my name under something I've never said. The
lack of control just rushed my adrenaline even though I was expecting
something like that. Thanks!

 Yes, you traced me correctly. And as Rob already noticed, that could
 be circumvented by spoofing the header a little more.

True. It wouldn't be so hard to send the message from another place.

 Also you were correct to notice, that the receiving server has the
 last word - however many servers today do -not- perform reverse DNS
 lookups. You can basically put into the EHLO message whatever you
 want and the receiving server will buy it.
 
 So with some effort we could make it look as if the message was
 actually received from fg-out-1718.google.com. At least as long as
 pidgeon.gentoo.org doesn't do reverse DNS lookups, which frankly I
 didn't check. :)
 
 --Paul

Unfortunately many times one cannot control the reverse records,
because the IP address pool belongs to the ISP. Nevertheless the SMTP
server logs the IP address which the message came from. It doesn't
matter if the message would be bounced or accepted because of the
(in)correct reverse resolving. Additionally there's the SPF [1] and I
believe the email system at gentoo.org uses it. If that's so and my
poor abused address :) was at a domain with SPF record imposing fail
policy, that message shouldn't be accepted at all. At best you'd get
something like:

   Domain of [EMAIL PROTECTED] does not designate 192.0.2.25
   as permitted sender.

Anyways the right thing to do is to ban the IP address which the
offencive message came from, not the email address. So, signatures
don't come to play here.

Except that even that can be faked.

The header is part of the payload, so can be whatever the user decides

Yes, you can insert headers before you send the message, but the SMTP
server which receives the message for local delivery always has the
final word. In this case pigeon.gentoo.org has added its headers to the
proof of concept message and we can see that the mail from [EMAIL PROTECTED]
was actually sent from elsewhere.

 No fully agreed, because if someone is signing his messages, all other
 subscribers have the possibility to see whether it's the same person
 or not. Not in the sense of real live identity but at least same Nick
 or Name. In my case for example Wolf Canis. Would know a message
 reach the ML with my Name but no signature or a different signature,
 could one relatively be sure about the fact that this particular

It also might be the same person signing with different keys or

 Why not? Every public key is downloadable, except one created a key
 and forgot to upload the public key, in this case is his/her signature

  1. Trouble saving
  Will signatures help if a mailing list (ML) receives spam?
  No. The admins won't accept arguments like Those mails weren't

  that's it.
 
 Is that true of every list? Do you know every list's owner or policy?

No, not really but the whole time I had in mind only this list and
those alike (anonymous, public and tech-oriented at the same time).
I apologize if I didn't make it clear.

 It's not only about spam and banning anyway. Someone could try to
 discredit you by posting inflammatory, abusive, racist or otherwise
 unacceptable posts in your name.

Not my name, the name of the account. Those are not the same thing,
especially in The Internet where everyone is anonymous by default. Some
use other people's names, others use nick names etc. Our names in this
list mean nothing. For example my account is expendable and I've
registered it exactly with the idea to get rid of it if it gets flooded
with spam.

 If every post you send to the list is signed, those unsigned messages
 lose credibility. By signing all messages, you are effectively saying
 If I didn't sign it, I didn't send it.

Unsigned messages have no credibility anyways. There's no need to use
your signature to imply it and actually you can't do that by design.

 Of course, this all falls apart on lame listservs like Yahoo Groups
 that strip all attachments, including PGP signatures.

Not my problem. I don't use them. :)

This is a nice list with helpful people.  There are other lists however, when 
it is not that rare for malicious (or unhinged) individuals to impersonate 
someone else and hijack their email address to publish offensive content.  
After a while using a digital signature (GnuPG or x509) becomes a habit.

 No doubt about that. :-)

Yep! :)

 
  There are other lists however, when 
  it is not that rare for malicious (or unhinged) individuals to
  impersonate someone else and hijack their email address to publish
  offensive content. After a while using a digital signature (GnuPG
  or x509) becomes a habit.
 
 That's exactly the case. ;-)


Two questions.
How would signing your emails to this list help you:
  - in avoiding the above to happen to you?
  - help you in case that happens after all?


Explain, please.

[gentoo-user] Mailing list and PGP/MIME

2008-05-24 Thread Wolf Canis
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

Hello all,

it seems that sometimes mails of mine doesn't
go to the list. :-(

I had this problem just a couple of hours ago. I
send a reply to the thread Need help with a regex
but the mail doesn't reach the list. I looked in
the archive and it doesn't reach there too. These
mail was send with PGP/MIME. I send this message at
6:03 PM CET.
At 10:13 PM CET I send the mail again but this time
without PGP/MIME - and this time the mail reached the
list. =-0

Now I'm wondering whether it could be that the
list server has problems with those mails or perhaps
those mails are simply blocked.

Is there a problem with signed messages?

Thanks in advance.

W. Canis

PS: Send at 11:12 PM CET without PGP/MIME

Sending w/PGP/MIME, email me off list if you get this.  I'll also send 
one w/pgp not mime encoded

I don't think that there is.  I can see both of your messages in the Need 
help with a regex thread.

The headers from the first have this:

DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed;
d=googlemail.com; s=gamma;

h=domainkey-signature:received:received:message-id:disposition-notification-to:date:reply-to:user-agent:mime-version:to:subject:references:in-reply-to:x-enigmail-version:content-type:from;

and the headers from the second message have this in them:

Kmail shows this in its GnuPG header on the first message:

Message was signed by [EMAIL PROTECTED] (Key ID: 0x293F7304A174B705).
The signature is valid, but the key's validity is unknown.


and the second message:

Message was signed by Wolf Canis (Common) [EMAIL PROTECTED] (Key ID: 
0xA174B705).
The signature is valid, but the key is untrusted.


Notwithstanding delays with googlemail, Gmane also takes some time before it 
shows posted messages.

Somewhat strange is it. On archives.gentoo.org the mentioned mails
aren't, only the second, but on gmane they are. I just looked there.

That looks good. :-)

It seems that that is the case. But how know one that the mail
is actually arrived?
The list delivers not to sender of a post. This is normally
absolutely correct on the one hand, on the other hand, if it
would, one would know whether a mail has the list arrived or
not.
