Get the Full MIME of an Email

Demonstrates the Chilkat Email.GetMime method, which returns the email as RFC822/MIME text containing the headers, body representations, related items, and attachments. The result is suitable for saving as a .eml file. This example builds a message and prints its MIME.

Background: MIME is the on-the-wire text format of an email — the exact bytes a mail server sends and receives. GetMime serializes the in-memory Email object into that format, assembling headers, encoding attachments as Base64, and adding the multipart boundaries that separate the parts. It is the natural way to persist a message (as .eml), inspect exactly what will be transmitted, or hand the message to another system.
