I am looking for some arguments for or against a given solution.
A public facing webserver hosts an aspx form and, based on user input, places the content of the form in XML within an email body. It then sends the message to an email address only used for this solution.
An internal system behind the company firewall reads the XML after retrieving the email and continues the process from there.
I have doubts this will be a robust solution and I am concerned about maintaining it, but I am open to here about pros, cons and alternatives which might be better suited for this case.
