As a subscriber to some number of Debian mailing lists via my current primary email address, [email protected] (yes, I understand, it's GMail, no one else cares), I wonder if this will resolve a recurring and persistent issue: receiving bounce messages from the Debian listmasters for mail resent through various mailing lists hosted at lists.debian.org to my GMail.com address. The bounces seem related to the resent messages failing DKIM and SPF validation; I do NOT believe they are generally related to the messages being actual spam. To date, I've received around 180 such bounce messages (at least, that's the number of email threads I have labelled "tech/deb/debianlistmaster"), dating back to April 2013. Looking at the last several (75 or so) threads, I seem to be getting bounce messages every week or two. The last 29 bounce messages were exclusively for the debian-qa-packages list. Prior to that (working backward to the beginning of 2025) I see occasional mentions of other lists (debian-mentors, debian-cloud, debian-toolchain) as well, tho the vast bulk of the bounces are still for the d-qa-p list. I reported the first bounce or two I got to listmaster@, but nothing seemed to happen. I'll admit that I was not as forceful about following up on my reports as I could have been. If it is useful or interesting, the most recent bounce message (reported to me on April 20) can currently be found at https://lists.debian.org/bounces/m4TYYw74H+CBKSXmLk+M3w . The headers from that message are also included below for convenience (slightly edited to wordwrap some things more usefully and prevent the "<newline>FROM" issue, and replace tab characters by 8 spaces as GMail apparently ate them): Thanks for your (and everyone else's) efforts on behalf of Debian and its users (and even me!) ----- ***** Beginning of Included Headers From Bounce Message ***** ----- >From MAILER-DAEMON Mon Apr 20 05:03:17 2026 Return-Path: <> X-Original-To: [email protected] Delivered-To: lists-bounce-debian-qa-packages=jayarejay=gmail....@bendel.debian.org Received: by bendel.debian.org (Postfix) id 42E5D205B5; Mon, 20 Apr 2026 05:03:17 +0000 (UTC) Date: Mon, 20 Apr 2026 05:03:17 +0000 (UTC) From: [email protected] (Mail Delivery System) Subject: Undelivered Mail Returned to Sender To: [email protected] Auto-Submitted: auto-replied MIME-Version: 1.0 Content-Type: multipart/report; report-type=delivery-status; boundary="55F0D205E4.1776661397/bendel.debian.org" Content-Transfer-Encoding: 8bit Message-Id: <[email protected]> This is a MIME-encapsulated message. --55F0D205E4.1776661397/bendel.debian.org Content-Description: Notification Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 8bit This is the mail system at host bendel.debian.org.
