This domain was set up for the purpose of providing a spam defense for a single family. There exist many emails at this domain all going to a small number of accounts
Occasionally one of the email addresses gets into the hands of an evil spammer. In this case, we abandon that particular address, and people sending email to it get a reply which hopefully gives contact information to legitimate people without making it easy for spam robots to detect the new email address. Sorry if you get one of these messages.
If you are getting email that you do not expect from this email address, or suspect that this computer has been hacked, please phone Australia (61) 3 9024 5505 as soon as possible.
