Mailcow-dockerized: mailcow on Google Cloud Compute Engine

[starcraft0429]

I have installed this mailcow(dockerized) on google cloud compute engine.
Btw Google always block 25 port outbound. so can't send any email.

Any solution on Google cloud server?

Reach out to Google Cloud support and get the port unblocked. We can't help you with that, as it is not related to mailcow itself.

Google doesn't open it.

Note: Port 25 is always blocked and can't be used, even through an SMTP relay using G Suite.

Then you'll have to switch to a different provider.
