I need help converting Mailgun’s Django email receiver into a C# MVC action. Below is a custom C# example:

using System.Web.Mvc;

public class EmailHandlerController : Controller
{
    [HttpPost]
    public ActionResult HandleEmail()
    {
        string fromAddress = Request.Form["email_from"];
        string toAddress = Request.Form["email_to"];
        string mailSubject = Request.Form["mail_subject"];

        // Process email content and handle attachments via Request.Files

        return new HttpStatusCodeResult(200);
    }
}

hey, i had similar issue once, so make sure reqest.form keys exist before processing. if you expect files, check reqest.files carefully, coz sometimes mailgun might send data diff. don’t assume fields are always there.

The controller action should include robust error-handling routines to account for possible variations in the expected form parameters. In my experience, it helps to validate the incoming keys before processing the request, and this can prevent issues if Mailgun sends unexpected data formats. Additionally, implementing logging of the entire request can make your debugging process easier when dealing with problems in production. Ensuring correct retrieval of both the text body and attachments is vital for reliable email processing.
