port 25 problem

Hello,

Please confirm that you requested the port 25 exception for Lightsail specifically as receiving the exception in EC2 does not carry over: https://aws.amazon.com/premiumsupport/knowledge-center/lightsail-port-25-throttle/

If you are still having trouble, please reach out to AWS Support: https://console.aws.amazon.com/support/home

Hello,

Assuming you followed these steps to apply for an exception, if your request was denied you may look to relay messages through a service such as SES. If you feel your request was denied incorrectly, you may want to open a support case and speak directly to the support team.
