Attach an Email to Another Email

See more Email Object Examples

Demonstrates the Chilkat Email.AttachEmail method, which attaches a copy of another email to this email object. The attached email is encapsulated in a message/rfc822 subpart. Because a copy is attached, later changes to the source email do not affect the embedded message. This example attaches one email to another.

Background: "Forward as attachment" produces exactly this structure: the original message is embedded whole as a message/rfc822 part rather than quoted into the body. This preserves the original's headers and formatting intact, which matters for forwarding to a mailbox that will re-parse it, or for reporting spam/phishing with the original evidence attached. Such parts are counted by NumAttachedMessages.
