Yes -- at least, it should.

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. :)
