I have turned off the relay at the exchange 5.5 server. I have updated the latest security patches for Internet Explorer and Outlook. And my boss still constantly gets "Undeliverable" or "System Administrator" messages that she knows she never sent. Is it that Klez virus? Is someone still using us as a relay? I'm at my wits end. Help.
My boss uses WindowsXP and OfficeXP, by the way.
