Google does authorize all addresses with their ~all SPF policy. However, there are freemailer conditions in some spam checks which penalize failure to use Googles servers.

@chaoskreator I've updated with notes on the header fields. You may want to review the RFCs particularly tools.ietf.org/html/rfc5322#section-3.6.2

comment the name of name server
@MadHatter The resolver will contain IP addresses of the local name servers which may or may not be published as nameservers for the local domain. In NS records they are always specified by name, although they may be specified by a short name such as NS1 if they belong to the domain.

comment DMARC is blocking email that seems like it should be allowed
adkim=r is the default and allows subdomains in the from address. I don't see any mechanism for disabling either SPF or DKIM validation of the from address. Enabling reporting provides detail on why things failed. I have found major carriers email reports daily.
