Count the Attached Messages in an Email

See more Email Object Examples

Demonstrates the read-only Chilkat Email.NumAttachedMessages property, which is the number of embedded emails represented by message/rfc822 MIME parts. These are counted separately from ordinary attachments and related items, and their indexes are zero-based. This example builds an inner email, attaches it to an outer email as a nested message, and prints the count.

Background: When you "forward as attachment," many mail clients embed the original message as a complete nested email rather than quoting its text. In MIME this appears as a message/rfc822 part — an entire email (its own headers and body) tucked inside the carrier message. Chilkat distinguishes three kinds of enclosed content: ordinary attachments (NumAttachments), inline related items (NumRelatedItems), and these nested messages (NumAttachedMessages). Use GetAttachedEmail to pull an embedded message into its own Email object.
