my emails goes to gmail spam from centos server

Hi, i am using latest centos version + cpanel.

I am trying to send mail from my email account but it goes to spam in gmail.

I am new to server setup, i don’t know how to setup mail server?

I am sharing header of the email which had gone to my spam box.

Thank you for your help!
