Routing Mail Through Amazon Web Services

  • Last updated on
In order to preserve the quality of the Amazon Web Services environment for sending email, Amazon Web Services enforces default limits on the amount of email that can be sent from EC2 accounts. Before you put your Barracuda Email Security Gateway into production, you need to request Amazon Web Services to remove the default email sending limits.

To do so, visit https://portal.aws.amazon.com/gp/aws/html-forms-controller/contactus/ec2-email-limit-rdns-request, sign into your Amazon Web Services account and fill in the three required fields on the form, as shown in Figure 1 below. While you await a response to the request, you can send small amounts of test email through the Barracuda Email Security Gateway.

If you do not take this step, you may experience large queues of mail and/or deferred mail that will eventually be delivered, but may be delayed.

Here is a recommended, generic Use Case Description that you might use in the form:

We are putting the Barracuda Email Security Gateway into a production environment and, as such, require consistent mail delivery.
