I hope you mean you changed the line in /etc/mail/sendmail.mc to read

	DAEMON_OPTIONS(`Port=smtp, Name=MTA')dnl

Do:
	# netstat -lpn | grep sendmail

If you see a line that contains "127.0.0.1:25", then you didn't stop
and restart sendmail after rebuilding /etc/mail/sendmail.cf from the .mc
file.  You have to do that.  sendmail only reads that when it starts.
Try "service sendmail restart" and repeat the netstat command.  It
should now have a line that contains "xxx.xxx.xxx.xxx:25" in it, where
the "xxx.xxx.xxx.xxx" is your machine's public IP address.
