We are currently testing a new option that may help people send mail without using a third party service. If you are interested in testing this product, please fill out the interest request form here1. Product Management for the feature may reach out to you.
We are also continuing to make improvements to our system to allow for some customers that have an established relationship with us to apply for an exception to be able to send directly on port 25. There are a number of IP reputation issues that have to be worked through for such a use case, so it should not be considered a common solution that will meet everyone’s needs.
We will have more updates on both of these items over time.

Finally, I got here, after almost two week of troubleshooting non-existence trouble on my GCP VM with sending email issues. Thinking I can use other port like 2525 (when I know port 25 is blocked by almighty Google) by twerking postfix to do my bidding yet without success.
As one of candidate that partake in Africa Google Scholarship on Google Cloud, I think Google product are far from what weare been told in the classroom after all, I can confirm that, yes all Cloud provider blocked port 25 by default as I had read lots of other people experience on port 25, but it is always open eventually by the provider. Google will do well if it can follow this practice.
I intending moving moving over 100 client on my hosting platform to GCP, but with this impasse, I will put it on hold until the sky is clear.
