Welcome to LQ.

Have you confirmed that your ISP is not blocking incomming port 25?

I asked them and they tell me they don't block port 25. I tried sendmail also. I get the same problem.????

Thanks for any help you could give.

Can you post the output from:
netstat -nlp

I have been testing this ??? I not sure but maybe they are blocking incomming on port 25. Any suggestions on how to confirm this ???
Thanks,

1) Ask your ISP.
2) When you know that your smtp server is working ask a friend to try connecting to port 35 on your system.
