Set the Reply-To Address of an Email

Demonstrates the Chilkat Email.ReplyTo property, which sets the MIME Reply-To header. This header automatically defaults to the From address, so you only set it when replies should go to a different address. There is usually a single Reply-To address, but you can supply a comma-separated list for several. Setting this changes only the Reply-To header — it does not change the SMTP envelope sender or the visible From header.

Background: When you hit "Reply," most mail clients address the response to the message's Reply-To header if present, otherwise to From. This is useful when the sending address is not the right destination for responses — for example, a newsletter sent from noreply@ but with Reply-To pointing at a monitored support inbox, or a message sent on someone's behalf that should be answered to a different person.
