I don't see the > "normal" stuff that breaks DKIM (i.e. a trailing mailing list footer, etc) It's our usual friend "c=simple/simple" -- vger just doesn't work with that. See here for reasons: https://lore.kernel.org/lkml/20211214150032.nioelgvmase7yyus@meerkat.local/ You should try to convince wdc.com mail admins to set it to c=relaxed/simple, or you can cc all your patches to patches@lists.linux.dev (which does work with c=simple/simple), and then b4 will give those priority treatment. -K
