Remove All Attachments from an Email

See more Email Object Examples

Demonstrates the Chilkat Email.DropAttachments method, which removes all ordinary attachments from the in-memory message. Related items (inline images, style sheets) and attached message/rfc822 emails are not affected. This example adds two attachments, drops them, and prints the count before and after.

Background: Chilkat distinguishes three kinds of enclosed content: ordinary attachments (files meant to be saved), related items (resources that support the HTML display), and nested attached messages. DropAttachments targets only the first category — useful, for example, when forwarding or re-sending a message body without carrying its original file attachments along.
