We have G Suite account with our domain name. And our server is Google cloud platform. we are using PHP for our development, we trying different code for sending mails, but cant receive any mails using mail functions, and we contact G suite account they said all the settings are working perfectly...this issue is regarding the google cloud platform, cloud reject the mails.
Is any additional settings needed to implement the google cloud platform to establish a connection with G suite account?
Should we have an AppEngine account for sending emails via code?
Any ideas on what might be happening here or what to test next?
Thanks in Advance...
