We have a plesk 8.2 server. A few days ago the smtp was stoped. I have cheacked the queue and found out 8000 spam email in the queue. Since then I am deleting the spam in the queue every few hours. I now that we are not an open relay. I need you to:
1. find how is it happening
2. close it down (no sppamers in my system)
3. find out the spammer ip.
4. make sure the smtp is working fine and fast.
5. install midnight commander
I need this ASAP
