need 587 TLS incoming and outgoing mail setup on server - 25 and 446 port are close our server by DC

I need my Linux server’s Goolgle SMTP to relay outbound incoming mail through Google Workspace over port 587. The basic ports are open but the SMTP handshake still fails, so I’m looking for someone to:

• adjust the Exim configuration to authenticate against my Google Workspace account (STARTTLS, AUTH PLAIN/LOGIN)
• add any required certificates, CA bundles, or OAuth-related settings so that Google accepts the connection
• send a couple of live test messages to prove delivery, making sure the headers show they passed through Google’s servers

*need 587 TLS mail on server - 25 and 446 port are close our server by DC, can you setup

*Google TLS for server - incoming and outgoing mail setup

*currentlly our server are not sending mail any notification to our admin mail

*also cron we run autometices we run manayly beause port 25-446 close by DC

We provide SSH access with the Google Workspace login on my Destop Laptop remotelly Google Meet and Team. Once the tests arrive successfully in Gmail and an external mailbox, Cron jobs the job is done.
