Save an Email to a .eml File

Demonstrates the Chilkat Email.SaveEml method, which converts the email object to EML and saves it to a file. An EML file contains the complete RFC822/MIME message — headers, bodies, related items, and attachments. This example builds a message and saves it.

Background: Saving as .eml writes the message in the universal MIME format that virtually every mail client can open, making it ideal for archiving, sharing, or handing a message to another program. It is the counterpart to LoadEml. A saved .eml also retains Chilkat's CKX- metadata headers (a way to store your own metadata with the email; they are always stripped before an email is sent), so .eml is the recommended way to persist a message even within Chilkat-based software. A separate Chilkat XML format (SaveXml) exists as an alternative, but offers no metadata advantage over .eml.
