Load an Email from MIME Text in a String

Demonstrates the Chilkat Email.SetFromMimeText method, which loads the email from MIME text (such as the contents of a .eml file) held in a string. On success, it replaces the entire current email. This example serializes one email to MIME with GetMime, then reconstructs it in a second object.

Background: This is the in-memory (string) counterpart to LoadEml, which reads MIME from a file. It is handy when the raw message text arrives from somewhere other than the filesystem — a database column, an HTTP response, or a message queue — letting you parse it straight into a fully populated Email object.
