DMARC problem, what triggers it & solution

Indication is an error message from yahoo, hotmail, gmail:

Message not accepted for policy reasons.

There is something very weird in my opinion regarding use of DMARC. If your domain has DMARC record, like in our example – to reject emails, that do not pass SPF test – and your recipient is using email forwarding or you are sending email on behalf of other domain (e.g. sending from GMail using own domain) – then DMARC checks will fail. Yes, that is true. DMARC check will say – hey, this domain is not authorized! You can add whatever you want to your SPF record – it will fail, as DMARC does not treat different domain names in email headers correctly.

The only solution is to use DMARC without any restrictions / rejections.

v=DMARC1; p=none;

Please correct me, if I am wrong.. It is August 2023 now.
