Receive mail messages in IRIS Interoperability Production

IRIS Interoperability formerly known as Ensemble comes with many built in adapters. It does not have a service or adapter to receive mail. I have written email service to receive mail messages via SMTP which can be passed to email operation.

Now I want to load-test a production which sends messages to an external mail server using email operation. The mail server team does not want me to send them thousands of messages.

I created iris-mail app to have a substitute mail server. I updated the server and port settings in the email operation. The outbound mail messages are sent to the substitute mail server, and I am able to count the number of messages received in iris-mail and compare it to the number of messages sent by the email operation.
