How to remove AWS EC2 Port 25 Throttling

You can request Amazon Web Services to remove the throttling on port 25 

using the Request to Remove Email Sending Limitations form. 

Note: you must sign in with your root account credentials. Amazon Web Services will request that you provide a use case description with your request to remove the throttle. Once your request is approved, they will alert you via email that the block has been removed.
