sendmail does not accept relayed mail

[ttest]

my sendmail program does not seem to response to connection from another mail server. I use telnet to connect to it, it does not show welcome message. I have restarted it a few times still does not work. can anyone help?

I want to change my question.
Right now, my problem is when I connect to port 25 using telnet from the same server machine, I can see the SMTP welcome message. But, when I connect from another machine, I can't see the welcome message. what could be wrong with sendmail?

Edit file /etc/mail/sendmail.mc and find line:
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')
Put dnl on the begining of that line, save changes (login as su) and then run:
m4 sendmail.mc > sendmail.cf
Restart sendmail.
