Google told you the reason right there in the log:
You might want to check out the provided link for details.
But I did not even receive the the email even in SPAM folder. What is the possible way to fix this?
Howdy,
Yeah it looks like Google bounced the email, so it wouldn't be delivered to the recipient. However, since it bounced, the sender should have a notification that it didn't go through properly.
Google's error message is indicating that it looks like spam.
My suggestion would be to review the documentation at the link they provided, including the "Bulk Sender Guidelines" and "mail forwarding best practices" in that guide, that would help explain how to resolve that.
Also, you may want to check and see if your IP address is listed on any RBL lists, this site here can help with that:
