 SPF and DKIM both passes with forwarder.com DNS records. The end receiver chooses the domain inside the "< >" i.e forwarder.com  to verify the DMARC record, which always pass as SPF and DKIM both passes with the same domain.

 Here SPF passes with forwarder.com ip address but DKIM passes with gmail's signature and since DMARC looks at the domain from From field in the message header , the attacker can only spoof email on behalf of any gmail's email address .
