rejected RCPT : Rejected relay attempt

We have a domain setup with a few email accounts created in G-Suite and have enabled split routing. We have changed the MX records of the domain to G-Suite and the email routing has been set to Local Mail Exchanger in cPanel. We have also set the email forwarding of the users which are not created in cPanel, but in G-Suite to forward to the user@domain_alias. However, the emails sent from the email accounts in cPanel to the email accounts in G-Suite bounce with the following error.
H=mail-pg0-f69.google.com [74.125.83.69]:38928 X=TLSv1.2:ECDHE-RSA-AES128-GCM-SHA256:128 CV=no F= rejected RCPT : Rejected relay attempt: '74.125.83.69' From: 'test@domain.in' To: 'test2@domain.in.test-google-a.com'
How to resolve this issue?

  Make sure you have setup SPF record and DKIM for the respective email Domain, this should solve the problem.

  The SPF and DKIM are fine. I get the following error in Google logs now.
  The error that the other server returned was: 550-Please turn on SMTP Authentication in your mail client. 550-mail-pf0-f197.google.com [209.85.xxx.xxx]:41226 is not permitted to relay 550 through this server without authentication.
