Get a To Recipient's Address Only

Demonstrates the Chilkat Email.GetToAddr method, which returns only the address part (not the friendly-name part) of the Nth To recipient. The index is zero-based. This example adds two To recipients and prints each one's address.

Background: When you need the machine-usable part of a recipient — the actual user@domain — GetToAddr returns it without the surrounding display name. This is what you want for validating addresses, removing duplicates, or checking against an allow/deny list, since the display name is free-form text and unreliable for identity.
