Question : TELNET PORT 25

I am trying to telnet to my UBUNTU box and i think i configured sendmail correctly. when i try to telnet port 25 I get (C:\Users\santosd72>telnet 192.168.1.2 25
Connecting To 192.168.1.2...Could not open connection to the host, on port 25: Connect failed) but on my linux i can telnet to local host port 25, with no problem.  and it appears that my Linux is listening on port 25

$ netstat -a
Active Internet connections (servers and established)
