Most likely SPF is broken and Google is complaining.  The only way around
this is to use SRS (Sender Rewriting Scheme) on your end; Google (!) it.
SRS is a bit of a bear to set up.

Frwarding mail to a machine outside of your control is essentially
broken due to relatively widespread adoption of SPF and DMARC, despite
the fact that those protocols have done nothing to reduce spam or
effectively improve email security. :(  Welcome to 2019.
