Hello, I am in need of help, as I installed the CLEAN CPANEL to my instance which is on google cloud. I configured everything successfully and all the domains are propagating to my IP as well. the problem I am facing right now is the MAIL SERVER, as I am able to receive the emails but cannot send the emails to any address as google cloud block the port 25. I have no idea what to do to resolve this problem, I tried to change the EXIM PORT to 26 and others but all in vain. Amy help would be appreciated. Thanks

  Hi, Google Compute Engine does not allow outbound connections on ports 25, 465, and 587. By default, these outbound SMTP ports are blocked because of the large amount of abuse these ports are susceptible. You cam use SendGrid, Mailgun, and Mailjet are Compute Engine's third-party partners that offer a free tier for Compute Engine customers to set up and send email through their servers

  Configure Mailgun on cPanel/WHM (Exim) Note: have used mailgun in the past a lot of their IP's are blacklisted & some providers block them outright
