Hello, We've reviewed and approved your request for the removal of the EC2 e-mail sending limitations on your Amazon Web Services account. There are no longer limitations on your account for any IPs and instances under your account. If you requested removal of e-mail sending limits on Amazon Elastic IPs, they've also been removed. Because reverse DNS record entries are commonly considered in anti-SPAM filters, we recommend assigning a reverse DNS record to the Elastic IP address you use to send email to third parties. Please use the form located at this link to request a reverse DNS entry: https://aws.amazon.com/forms/ec2-email-limit-rdns-request Note that a corresponding forward DNS record mapping only one domain to one Elastic IP address must exist before we can create the reverse DNS record on our side. Thank you for your inquiry! Best Regards, http://aws.amazon.com ---- Original message: ---- AWS AccountId = xxxxxxxxxxxx UseCaseDescription = Please "remove" following reverse DNS lookup setting.
