Adding special headers
Once the headers are enabled, you add them to your message before sending it to SmartRelay. This is generally done within your normal programming environment, such as Java, which is used for most of the examples shown in this guide. The only exception is the HTML2 header feature, which automatically adds a range of special headers to email messages using <input> tags embedded in the text/html body.
See the relevant feature description for more about enabling the special headers.
