A customer asks a question. The email, either a direct message or a re-routed message from an online support page, is sent to iMail.
iMail processes the message. If it understands the message, and can provide a suitable answer, it responds immediately to the customer.
If iMail cannot provide an answer, the message is forwarded to a support representative.
The support representative sends a response back through iMail to the customer. iMail processes, and learns from, the message, so that during the processing of a subsequent message of similar meaning, it can provide an immediate response.
