Using Cloudmailin

Cloudmailin is a great way to let your AppHarbor application receive emails with very little effort.

To use Cloudmailin, do the following:

  1. Provision the add-on from the catalog
  2. Follow the link to you Cloudmailin dashboard and configure the url that you want Cloudmailin to POST to when an email is received.
  3. Make sure that your application can receive POST from Cloudmailin at the target url

To accomplish item 3, you can use the controller action below:

public ActionResult Create(Email email)
    return new EmptyResult();

With the Email class looking like this:

public class Email
    public string From { get; set; }
    public string Plain { get; set; }
    public string Subject { get; set; }

You can add additional fields as required. All the fields posted by Cloudmailin are in their documentation.

Cloudmailin provides a great debugger for debugging your controller locally.

If you find that ASP.NET complains about dangerous requests, you can add this to your web.config:

    <httpRuntime requestValidationMode="2.0" />
