I'm stumped. And I'm not a guru.

I think I have a network setup problem on my Linux box, but I'm not
sure what to look for.

Problem:
Trying to get sendmail working. On linux box, cannot telnet to my
ISP's smtp server.

What I've tried:
>From linux box: telnet my-isp-smtp-server 25
I get: telnet: Unable to connect to remote host: Connection refused
I can ping it fine though.

>From my windows box, when I try the same telnet, it works fine and I
can do a manual email out, and it gets delivered fine.

Any help would be greatly appreciated. I've been working on it for a
few evenings now, and I'm out of ideas.

Here's my network setup, just in case:
RoadRunner cable modem --> wireless router --> linux box & windows
boxes
Now, my linux box does NOT use dhcp, it has a fixed 192.168.x.x
address.
My windows box DOES use dhcp. The wireless router is the dhcp server
too.
