When I try to release my Elastic IP address through the AWS Management Console, I get an error similar to the following:

​"Error [IP address]: The address with allocation id [allocation id] cannot be released because it is locked to your account."

What does this mean, and how can I fix it?

This error message is generated when a reverse DNS (rDNS) record has been created for your Elastic IP address.

An rDNS record can prevent the Elastic IP address from being flagged as spam by some anti-spam entities. Because the record is meant to identify your account or organization to these entities, the Elastic IP address is locked to your account for as long as the rDNS record exists.

To remove the rDNS record so you can release the Elastic IP address, use the Request To Remove Email Sending Limitations form to contact AWS Support. Add your Elastic IP address in the Elastic IP Address 1 field, and in the Use Case Description field, request for the rDNS record to be removed.
