I'm guessing you are saying sendmail just isn't binding your external 
interface.. If you telnet to it from a remote box on port 25, you are getting 
connection refused?

Look in your sendmail.cf for:
# SMTP daemon options

You may have a line that looks like:
O DaemonPortOptions=Name=MTA, Addr=127.0.0.1

Add another line that looks like:
O DaemonPortOptions=Name=MTA, Addr=192.168.1.1

where 192.168.1.1 is YOUR external IP.
