SENDMAIL - How to prevent telnet into my server on port 25
I have removed my telnet package and still people from the outside can telnet myhost.mydomain.com 25 and see my version/etc of sendmail. I thought removing my telnet package would fix this, it didnt. Does anyone know how I could prevent people from telneting in on port 25. I even have telnet disabled, but for some reason telnet on port 25 is still allowed.
Thanks in advance
