How can email forwarders be used for parental control?
Give your child an email address (child-name@mybusiness.com) that redirects all email to sent his address (child-name@mybusiness.com) to another existing email address (parent@mybusiness.com). Even if your childs email address is a POP3 email address with user name and password this is still possible to do. This makes it possible to follow what your child does on the internet and how others communicate with your child.
