ADAM can take advantage of a feature of any e-mail server* which allows all mail that is sent through the server to be duplicated into a mailbox. ADAM can then scan this mailbox and match the mails that have been set to parents’ email addresses. If an e-mail matches, it is copied and made available to staff with the appropriate privileges within ADAM.
This means that ADAM will automatically keep track of all e-mail correspondence sent from your parents to the school, or from your school to your parents!
* This is known to work with Microsoft Exchange Server and may well work with other types of e-mail servers.
