DKIM fails on many mailing lists. This list, for example, modifies your subject to add "[gentoo user]" but leaves the DKIM signature intact. If the sender has a p=reject DMARC policy, that can make his messages "disappear" for recipients who check and enforce DMARC. Stefan was putting forth another much more plausible explanation for Joost's "missing" messages: he rejected them. Blaming lists.gentoo.org (or any other MTA) for not retrying after a 4xx without evidence is seeing hoof prints and thinking zebras. Ockham's razor: you fucked up.
