Count the Bcc Recipients of an Email

Demonstrates the read-only Chilkat Email.NumBcc property, which is the number of blind carbon-copy (Bcc) recipients. Bcc recipient indexes are zero-based and can be inspected with GetBcc, GetBccAddr, and GetBccName. This example adds two Bcc recipients and prints the count.

Background: Email has three recipient lists: To (primary), Cc (carbon copy), and Bcc (blind carbon copy). The key difference is visibility: To and Cc addresses appear in the delivered message's headers for everyone to see, but Bcc recipients are hidden — the Bcc header is stripped before delivery so no recipient can tell who else was blind-copied.
