inanzzz | Sending emails with AWS SES within Symfony application using PHP AWS SDK

In this example we are going to sent "text" emails with Amazon Simple Email Service (AWS SES).

Installation

Run composer require aws/aws-sdk-php to install AWS SDK for PHP library.

AWS SES configuration

Go to "Identity and Access Management" dashboard and add a new user by assigning "AmazonSESFullAccess" policy to it. The secret can be seen only once at the time of creating a new user so make sure you note it somewhere safe. Also make sure that the user cannot login to AWS like normal person would do so the "Group" should be "None" instead of something like "AdministratorAccess" so on.
