Get an Attached Message as an Email Object

Demonstrates the Chilkat Email.GetAttachedEmail method, which copies the Nth embedded message/rfc822 MIME part into another Email object. The index is zero-based (valid values run from 0 through NumAttachedMessages - 1). This example attaches an email and then extracts it back into its own object.

Background: When a message forwards another email as an attachment, that nested message is a complete email in its own right. GetAttachedEmail turns it back into a fully navigable Email object so you can read its subject, sender, body, and even its own attachments — essential for processing forwarded mail, or for tools that unpack reported spam/phishing to examine the original.
