Set the X-Mailer Header of an Email

Demonstrates the Chilkat Email.Mailer property, which identifies the email software that sent the email. It corresponds to the MIME X-Mailer header. This example sets the mailer string and shows it in the generated MIME.

Background: X-Mailer is an optional, informational header — the X- prefix marks it as non-standard — that names the program used to compose or send the message. Mail servers do not require it and it has no effect on delivery; it is mainly useful for diagnostics and analytics. Because it is self-reported, it is trivially spoofable and should never be relied on for security decisions.
