Count the Messages in a multipart/digest Email

See more Email Object Examples

Demonstrates the read-only Chilkat Email.NumDigests property, which is the number of message/rfc822 parts contained within a multipart/digest enclosure. If no such enclosure exists, the value is 0. Digest indexes are zero-based; use GetDigestEmail to retrieve an individual bundled message as its own Email object. This example loads a digest email and lists each message's subject.
