[ I'm copying this to some of the possibly-relevant people because it's not at all clear that just sending it to the mailing list will reach anyone. My apologies if I've included some of the wrong people. ---rsk ]
One of my users is on this mailing list and forwarded this to me. (I run the mailing lists for several LUGs as a free service to the Linux community, and my user base has a bunch of Linux, Unix, open-source, etc. people.) As far as I can tell, this instance of the mailing list is very badly broken. So far I've noted: 1. The host it's coming from fails FCrDNS checks. That means that a lot of operations won't allow mail from it. FCrDNS compliance has been a baseline requirement for legitimate mail systems for ~20 years. 2. The List-ID header is completely wrong. 3. The other RFC 2369 headers are missing. 4. The Sender field is missing, thus the originators of messages aren't identified. 5. I need to double-check this against the RFC, but it looks to me like the Message-ID fields are malformed. There's probably more, this is from a quick glance. I don't know who's changed what or why, but I would suggest reverting that change ASAP. If you need help doing that or setting this up or whatever, I'm willing to assist: I've been running mailing lists for something like 40 years (manually, then with Majordomo, then with Mailman) and currently run about 30 of them across 6 different domains. ---rsk/Rich Kulawiec/[email protected]
