Get the Number of IMAP Attachments

Demonstrates the Chilkat Imap.GetMailNumAttach method, which returns the number of ordinary attachments on a message. The only argument is the Email. This example fetches only the headers and reports the attachment count.

Background: A header-only fetch downloads no attachment bodies, so the Email object's own downloaded-attachment count can be 0. GetMailNumAttach instead reads the ckx-imap-numAttach metadata, giving the true count — which is what you want when building a message list that shows whether each message has attachments.
