Lift Port 25 Outbound restrictions on our EC2's

Hi User

AWS imposes restrictions on outbound port 25 traffic from EC2 instances to prevent spam. To lift these restrictions, you need to submit a request to AWS, detailing your use case. You've mentioned submitting a request 48 hours ago.

Unfortunately, there's no direct public way to check the status of your request. The typical process involves waiting for an email response from AWS.

While waiting for the request to be processed, it's worth checking for potential issues on your end:

• Security Groups: Ensure your EC2 security group allows outbound traffic on port 25.

• Network ACLs (NACLs): Verify that your NACLs permit outbound traffic on port 25.

• Route Tables: Confirm that your route table correctly directs traffic to the internet gateway.

• Instance Configuration: Check if your EC2 instance's OS firewall (e.g., iptables, Windows Firewall) is blocking port 25

• AWS Documentation: While there's no specific documentation on checking request status, you can find general information about port 25 restrictions and the request process here: https://aws.amazon.com/premiumsupport/knowledge-center/ec2-port-25-throttle/  

• AWS Support: If you haven't already, open a support ticket with AWS for expedited assistance.
