We use the HttpWebRequest() class

We got this project from the Android team and they used Bounce Castle with built in support for creating S/MIME messages. Sadly, this support is not available in the C# port of the library.

As a last resort, we could try and build the mssage using stringbuilder, and use the cms-classes in Bounce Castle for the encrypt/decrypt of the message body.
