You need the destination address to not run dkim spf or dmarc on the forwarded emails with rewritten destinations. I came across this when forwarding everything to gmail. Gmail is smart enough to accept this for mail originally destined for an address you enabled as "send from". However, mail sent to e.g. retailName@domain.com will fail the checks and never be delivered.
