I wanted to ask, how does it do that? But then I googled around: https://serverfault.com/questions/611575/will-mailing-lists-break-if-spf-is-too-restrictive/611631#611631 https://serverfault.com/questions/611575/will-mailing-lists-... It seems that SPF, DKIM and DMARC can all cause failure wrt. mailing lists depending on how messages are rewritten.

SPF will always fail. OTOH, when the mailing list doesn't do dumb stuff like mutating the subject or the body, DKIM will succeed.

  SPF really shouldn't fail. SPF checks use the envelope address, not the From header. See also https://en.wikipedia.org/wiki/Sender_Rewriting_Scheme https://en.wikipedia.org/wiki/Sender_Rewriting_Scheme
