You need to explain what you are doing a bit more clearly. I can't figure
out what "i telnet to my isp port 25" means, especially since it seems to be
something you want to do "before i can activate my sendmail". And what does
"Using the IP and name of my isp" mean, and how does it differ from "i
telnet to my isp port 25"?
If you run sendmail (either directly or through inetd), it will listen for
incoming connections on whatever host it is running on. So if, for example,
your machine is IP address 12.34.56.78, doing a "telnet 12.34.56.78 25"
should return the sendmail banner.
If you are not yet running sendmail on the host, you will (correctly) get
this message: "telnet: Unable to connect to remote host: Connection
refused". This means simply that sendmail (or an equivalent MTA) isn't
running yet on the host.
If you are trying to connect to port 25 on some other host (I'm still
stumped about what "my isp port 25" is), it will answer if it is running
sendmail, refuse if it is not. (Actually it is a bit more complicated, as
firewalling rules come into play too ... but let's not get too complicated
yet.) Whether that other host is running sendmail has nothing to do with
your ability to run sendmail on your host.
It is also possible that you are trying to do this through a
firewall/router. That adds additional difficulties, and I won't even begin
trying to explain them until I know more about your actual setup (but you
can read the Firewall HowTo at www.linuxdoc.org to get an idea).
So ... try again. Explain in more detail what you are doing, quoting exact
commands, exact responses, and explaining what hosts are involved.
