I think SPF is happy if the bounce address (envelope from) is replaced but the From: header is intact.

- toast0 13y agoTo pass DMARC, you need to have either DKIM pass, or SPF pass when the envelope sender and the From: header are aligned (whatever aligned means... generally within the same domain). Because the envelope from headers are very likely changed to the mailing list, the SPF pass doesn't help with DMARC. And since the mailing lists very likely alter the messages (to put footers), the messages probably don't pass DKIM either.
