Load an Email from MIME in a StringBuilder

Demonstrates the Chilkat Email.SetFromMimeSb method, which loads an email from the MIME text stored in a StringBuilder object. On success, it replaces the entire current email. This example serializes one email into a StringBuilder with GetMimeSb, then reconstructs it in a second object.

Background: This is the StringBuilder counterpart to SetFromMimeText. When the MIME already lives in a StringBuilder — perhaps assembled or edited there — passing it directly avoids converting to an intermediate string, which is more efficient for large messages.
