It's only required if there is no DKIM signature on the original message (see my musings on this subject here: https://people.kernel.org/monsieuricon/subspace-mailing-list-server#appeasing-dmarc ) If there is no DKIM signature on the original mail, then yes, the DMARC verification server is supposed to perform an "alignment check" to make sure that the envelope-from domain matches the in-header From: domain. Rewriting the From: header is a terrible fix for this, though, as it breaks the patch flow (unless tools have specific kludges to fix this, like Patchwork). A much better solution is to have everyone properly DKIM-sign their outgoing mail. :) -K _______________________________________________ Patchwork mailing list Patchwork@lists.ozlabs.org https://lists.ozlabs.org/listinfo/patchwork
