It maybe that your mta (mail service on linux) is being used as open-relay, you better check as that can cause you a lot of trouble.

check it here http://mxtoolbox.com/ and type this on the search box next to the orange button smtp:domain.com using your domain name. It will tell you if you have a open relay, in which case you need to fixed ASAP.
