Lightbulb port 25 anonymous mail through telnet

I have setup an email server by following howtoforge guide "". Mail server is working perfectly. But the problem is that when someone telnet through port 25 he can send email to internal users without authentication.

I have setup mail server on domain anyone can connect to that domain via telnet on port 25 and send mails to email id's on same domain like from to I want to stop this anonymous mail sent through telnet. if i close port 25 i don't receive any mail.

Any way to solve this problem.
