No. I'm saying that every mail supplier will eventually enact DKIM, killing mail lists usage by their users.
I optimistically hope that my email provider, who is also my ISP, will be one of the last to succumb, and that before they do a solution will be found to allow email lists to continue.
Heh :-)
Yes, same here.
There are "solutions". One is to not change or add anything to emails that come from a DKIM domain. Which means, not adding [opensuse-support] to the subject line, or not adding a footer with important information to the emails, when they pass the server.
Obviously, that solution impacts the usability of the lists.
The other method is to change the "from" address - example:
From: On behalf of Dave Howorth <support@lists.opensuse.org>
This other method is not liked.
Another method would be for DKIM to acknowledge that email lists DO exist and modify their rules accordingly!
It is up to each mail supplier. For instance, on GMX, looking at mauro's posts (his ISP sets up DKIM), I see: X-Spam-Checker-Version: SpamAssassin 3.4.2 (2018-09-13) on mx1.infra.opensuse.org X-Spam-Level: X-Spam-Status: No, score=-0.1 required=5.0 tests=DKIM_SIGNED,DKIM_VALID, DKIM_VALID_AU,FREEMAIL_FROM,RCVD_IN_DNSWL_BLOCKED autolearn=disabled version=3.4.2 X-Spam-Virus: No That test is done by openSUSE servers. I can not see if GMX does anything; it may be here: X-GMX-Antispam: 0 (Mail was not recognized as spam); Detail=V3; X-Spam-Flag: NO X-UI-Filterresults: notjunk:1;V03:K0:TqZjgr84hzo=:WJIeY0gf6hWyN4mzPWRlffMZ8m UsjxAXTX9wdUoLwucKKOgNvYXQamMGjOB1aLvFDBkpUmOovoc/DYq6gYpSUevuimZxYBkMTKu ... But it is encoded in an unknown way. Telefonica.net does it differently: X-TnetIn-Information: AntiSPAM and AntiVIRUS on asavin03 X-TnetIn-MsgID: 4CxJvy4LWkzvQq6.A4FA7 X-TnetIn-SpamCheck: no es spam, community:mailing-list DKIM_NONE SPF_PASS X-TnetIn-From: support-bounces@opensuse.org X-Spam-Status: No My provider is aware that it is a mailing list and passes it. It even signals the "from" that did the resending. IMHO, my provider is acting correctly. I would need to see a direct email from mauro or somebody that has dkim to see how telefonica reacts to a non list email. Ah, I have one, a bugzilla email: DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=suse.com; s=susede1; ... X-TnetIn-Information: AntiSPAM and AntiVIRUS on asavin03 X-TnetIn-MsgID: 4CyHjP6jkszvXRp.A088D X-TnetIn-SpamCheck: no es spam, clean DKIM_NONE SPF_PASS X-TnetIn-From: srs0=w4l7=fw=suse.com=bugzilla_noreply@opensuse.org X-Spam-Status: No Claims "DKIM_NONE", which I don't understand. We know how libero reacts to a DKIM signed email: X-IOL-DMARC: fail_quarantine con il dominio libero.it X-IOL-DKIM: fail="signature verification failed" con il dominio d=libero.it Authentication-Results: smtp-25.iol.local; dkim=fail (signature verification failed) header.d=libero.it header.b=XT2PEt/i
But who knows :)
