I am running MS Exchange 2003 behind a firewall. Yesterday I went into ESM Server/Queues I found that there is a large volume of spam email coming from administrator@"mydomain".com being sent to domains all over the globe. I froze as many as I could but new ones keep popping up.
I have checked and found that my server is not a relay server.
I've tried to run RootkitRevealer in a console window but I keep getting the error message that it must be run from a console window.....
I am new to Exchange and am looking for some guidance as to my next step and or some reference material.
Thank you in advance for your help.
