It was to <[email protected]>. The resubmitted message eventually made it through last Tue, Oct 20th, after a week of being held: Received: from ohno.mrbill.net ([184.94.207.190]:57765 "EHLO ohno.mrbill.net" rhost-flags-OK-FAIL-OK-FAIL) by eddie.linux-mips.org with ESMTP id S23991030AbgJTMxVN8USJ (ORCPT <rfc822;[email protected]>); Tue, 20 Oct 2020 14:53:21 +0200 Received: from ohno.mrbill.net (localhost [127.0.0.1]) by ohno.mrbill.net (Postfix) with ESMTP id E173B1E0DF9; Tue, 13 Oct 2020 22:55:12 -0500 (CDT) X-Original-To: [email protected] Delivered-To: [email protected] Received: from cvs.linux-mips.org (eddie.linux-mips.org [148.251.95.138]) (using TLSv1 with cipher AES256-SHA (256/256 bits)) (No client certificate requested) by ohno.mrbill.net (Postfix) with ESMTPS id 84C0D1E0915 for <[email protected]>; Tue, 13 Oct 2020 22:55:10 -0500 (CDT) which I think does coincide with the revival of mrbill.net services: Domain Name: MRBILL.NET Registry Domain ID: 1373333_DOMAIN_NET-VRSN Registrar WHOIS Server: whois.namecheap.com Registrar URL: http://www.namecheap.com Updated Date: 2020-10-19T15:39:08Z and makes me conclude my suspicion was right. > > So local hot wiring of name resolution (which I suppose could be as easy as > > adding a /etc/hosts entry rather than going through the hoops of setting up > > a manipulated name server) might be good enough to get at the web pages, but > > not to get the list going. > > Ya ... email tends to be more reliant on DNS.

The admin of linux-mips.org, a friend of mine, has vanished since the outbreak of the COVID-19 pandemic in Europe last March -- I do hope nothing wrong has happened to him and he does surface sometime. Anyway, he's the only one who can remove a stale /etc/hosts entry here for vger.kernel.org, which prevents me from posting to any Linux kernel mailing lists hosted there unless I resort to some horrible hacks, which in turn tend to randomly break sending e-mail elsewhere. Sigh... Maciej
