No, but if the mailing list server rewrites when the sender has a
reject policy then the email gmail receives will no longer violate
the policy so they won't put it in the spam folder.
Based on some reports, I don't think this is how the Gmail
implementation works. It will discard mailing list mail for senders
with a DMARC policy that does not set p=reject, too.
