hi guys, is there a way to disable the telnet on port 25 without affecting
the smtp server?

You mean disabling telnet connections to your mail server's TCP/25? Not by Sendmail alone. The firewall made by Stonesoft disables TCP/25 connections after a specified time of non-activity --a simple way of guessing that connections to the mail server are made manually, because the required SMTP activity per unit of time, is not there. And if I remember correctly, a Lotus Notes server also got me one time 'coz it detected the escape characters in a telnet connection. I got "through" later using the Solaris mconnect tool... though the simpler and more common netcat utility will work too.

or how can i hide the sendmail version when telneting on port 25?

Lawrence beat me to this question already :)
