I need help adapting Mailgun’s Django email receiver example into a C# MVC controller. Can someone provide a sample in C#?

[HttpPost]
public ActionResult HandleMail()
{
    string fromAddr = Request.Form["fromKey"];
    string toAddr = Request.Form["toKey"];
    string mailSubject = Request.Form["subjectKey"] ?? "";
    string messageBody = Request.Form["bodyKey"] ?? "";

    foreach (string fileName in Request.Files.AllKeys)
    {
        var uploadedItem = Request.Files[fileName]; // Process file as required
    }
    
    return new HttpStatusCodeResult(200);
}

The provided sample is a good starting point. In my experience, working with inbound email controllers requires careful validation and error handling. It is often beneficial to check if each parameter exists and log any missing data. When adapting a Django example to C#, consider how MVC model binding can also help reduce boilerplate code if you decide to use view models for form data. Additionally, ensure proper exception handling especially when processing file uploads to manage any potential issues such as large file sizes or invalid file types.

i had similar probs adapting mailgun example to mvc. check all keys carefully since mailgun can send diff names sometimes and dont forget wrap file processes in error handling, so you catch any random device messups

While I was adapting Mailgun’s Django email receiver example to a C# MVC environment, I discovered the importance of verifying the request’s content type and encoding to ensure proper data extraction. I experienced situations when malformed input required additional error handling, which made logging indispensable. In my case, validating and normalizing the keys from Mailgun helped streamline the process. Also, I found experimenting with test requests in a local environment using mock objects can save a lot of debugging time down the road.
