Re: Spam from the list?

[Hans <hans.ullrich@loop.de>]

Hi all,
I believe, I found the reason, why mails are marked as spam and others not.

All spam mails shjow this entry in the header:

--- sninp ---

Authentication-Results: mail35c50.megamailservers.eu; spf=none 
smtp.mailfrom=lists.debian.org
Authentication-Results: mail35c50.megamailservers.eu;
	dkim=fail reason="signature verification failed" (2048-bit key) 
header.d=debian.org header.i=@debian.org header.b="pDp/TPD5"
Return-Path: <bounce-debian-devel=hans.ullrich=loop.de@lists.debian.org>
Received: from bendel.debian.org (bendel.debian.org [82.195.75.100])
	by mail35c50.megamailservers.eu (8.14.9/8.13.1) with ESMTP id 
425I9ZEK112497
	for <hans.ullrich@loop.de>; Tue, 5 Mar 2024 18:09:37 +0000

White mails get the dkim=pass and spam mails got dkim=fail (as you see above).

However, I am not much experienced with DKIM, but as far as I read, it has 
soemthing to do with key exchanges. 

But who must exchange keys? I see also bendel.debian.org and a bounce message.

Can that be the reason, that bendel.debian.org and megameilservers.eu has some 
problems with the keys?

On both I can not take a look and have no influence to it, but mayme the admins 
of bendel.debian.org do know more.

Thanks for reading this,

Best regards

Hans
