What email to be tracked?
What about the details...
What do they mean by 'subscriber'?
Does the email retention apply to Oz-based services only?
Or accessed through an Australian ISP?
Web-based email?
What if I'm in Oz but using an overseas-hosted mail service (encrypted or not).
What if I'm outside Oz accessing an Australian-based email service.
Are Facebook messages outside of the scope of this? Why?
etc..
