Perl

Remove a Single Attached Message from an Email

Demonstrates the Chilkat Email.RemoveAttachedMessage method, which removes the Nth message/rfc822 sub-part (an attached email) from the message. Indexing begins at 0. This example attaches an email, removes it, and prints the attached-message count before and after.

Background: Attached messages (forwarded emails carried as message/rfc822 parts) are counted and indexed separately from ordinary file attachments and related items. RemoveAttachedMessage targets just one nested email by index — useful, for example, when trimming a bundled digest or stripping a forwarded original before re-sending.
