Block by IP address of the sending server or by domain until you can get a handle on it. What are you using for anti-spam?

Block those spam IP's straight away if you have them. Aren't you using AS agents/Edge or a service provider? Not subscribed to any IP Connection filtering/Reputation etc..etc..Sukh

If the messages are already in the queues, then there isn't much you can do. Tell users not to send email and then delete the queue. Exchange is simply processing the messages that have already been delivered and the queue viewer will struggle to keep up. Unusual for Exchange 2007 to get attacked in that way, so you need to establish what method was used. Unfortunately the usual cause is admin misconfiguration, open relay, or authenticated relaying enabled on port 25. Simon. Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.
