We have a couple domains hosted rackservers.com.au. Recently our account go suspended without any notice. I then filed a ticket and soon got the answer:'There are some one forging email accounts from your domain, and they have been sending out spam emails. So we do not want you here anymore, take your backup and go.' I am quite shocked by such attitude and more confused by the actions we should take under such situation. Should I take my back up and go?Should I ask them for more details?How can I prevent this from happening again in the future? 
Evil Spam Emails caused hosting account suspension!
