I have similar problem (or may be the same). I use ubuntu 9.10 with ispconfig3. Now anyone can use my server on port 25 to send emails to the email boxes on my server. I want to know how to stop this. If the email is not for mines mail boxes there is response '5.7.1 Relay access denied', which is good, but when it is for my boxes is not good.
