I received a bounced message in my inbox today from a recipient that I never sent mail to in the first place.. Could somebody be using my Exchange server to send mail using my e-mail address? I have locked our server down from being a relay server, and I double checked the settings and everything still looks good. Could this be a virus? Or just somebody that used my e-mail address as the return address on a e-mail they sent out?
Thank you for your thoughts.
