Hi, I'm using oracle cloud free tire since early Jun 2021 before oracle blocked port 25. And as stated in there article that will apply new tenancy only. I was using website in the instance I created in oracle and my email was working fine. I had to redo my instance middle of September 2021 and the mail service was still working. Now when I try to do instance the port 25 is blocked. So my website notification also not working. Can anyone please advise me how to fix this issue? According to the documentation port 25 is blocked only for new tangency. Why my port 25 blocked suddenly. Please advise. Thanks
