        // The AddHeaderField can be called to add any header field.
        // If the header field already exists, AddHeaderField replaces it.
        Email email = new Email();
        email.addHeaderField("X-Priority", "3 (Normal)");

        email.addHeaderField("X-Priority", "1 (High)");

        email.addHeaderField("X-Priority", "5 (Low)");

        // The X-Priority value ranges from 1 to 5, with 1 being
        // high priority, 3 is normal, and 5 is low.
        // You may set X-Priority to the number alone:

        email.addHeaderField("X-Priority", "1");

        // Including extra text, such as (High), should not
        // affect how the header is interpreted.
        email.addHeaderField("X-Priority", "1 (High)");
    }
