Spam in Australia:
Under the Spam Act, it is illegal for unsolicited commercial electronic messages that have an Australian link to be sent, or cause to be sent. A message has an Australian link if it originates or was commissioned in Australia, or originates overseas but has been sent to an address accessed in Australia.

Spent the day dealing with an exchange server that had been compromised. As a result, heaps of spam emails were in the exchange mail queue. Manually removing them is a major pain in the rear. Fortunately, others have shared how to clear the Microsoft Exchange mail queue of thousands for spam mails.
- Stop the SMTP service.
- Create a new spam folder for example in
C:\Program Files\Exchsrvr\Mailroot\vsi 1\Spam
- With the SMTP service still stopped, move all the messages from the
C:\Program Files\Exchsrvr\Mailroot\vsi 1\Queue
to the spam folder (in case you need to retrieve a message)
- Restart the SMTP service.
Of course prior to doing that, the instructions at this Microsoft KB How to block open SMTP relaying and clean up Exchange Server SMTP queues in Windows Small Business Server is quite helpful in showing how to make sure your exchange server is not an open relay. It also shows how to test if it is an authenticated relay attack that is the problem.
