Valigator email validation service

This project provides email address validation, disposable address detection and typo suggestions.

It was developed for Eventsense and is designed to execute via an AWS Lambda exposed through Amazon API Gateway.

Configuring for Application Load Balancer

To configure this project to handle requests from an Application Load Balancer instead of API Gateway change the base class of LambdaEntryPoint from Amazon.Lambda.AspNetCoreServer.APIGatewayProxyFunction to Amazon.Lambda.AspNetCoreServer.ApplicationLoadBalancerFunction.
