Having serious SPAM email issues..server overrun with spam please HELP

[3rik7]

Good morning,
We've suddenly started experiencing a serious problem on our exchange server and I'm not really sure of the cause. We have over 11,000 outbound queues (internet mail smtp connector) created (some with message counts over 1,000) that are all trying to send out a bogus email message about "big mac sell out promo). The sender id is not an email address from our domain and the recipients are completely random. I'm not sure what's causing this our how to prevent it. At this point, I'm just trying to delete the mail from the queues but I'm concerned that they are queuing up as fast as I can delete them. Any help would be greatly appreciated!

First I would suggest testing to see if your server is an open relay. You can go to

and test it there. Check that first and if you are not an open relay then I assist further.
