Email System in Google Cloud

[designd7gos]

I have installed DirectAdmin on AlmaLinux OS - Google Cloud. Everything works smoothly except for the email service, which cannot send emails, though I can still receive them.

Currently, Google Cloud has blocked port 25, and it cannot be modified. I do not want to use third-party SMTP Relay because I have many domains on the system, and configuring SMTP Relay for each domain would take a lot of time.

Is there any other solution available at the moment? Thank you.

you can config global relay without touching your website script.

Is this approach feasible when I have multiple domains on the system, and each domain has several different email accounts?

yep, but you need to make sure 3rd party will accept from your server without domain validate.

Example: create your own mail server from other datacenter that's can open outgoing port 25 for you and then put credential into directadmin smartroute.

Thank you, I was able to resolve the issue by configuring Exim according to the instructions from SMTP2GO.
