If you want sendmail to listen on both local loopback interface and the public IP, you should use:

-- Sendmail.mc

define(`SMART_HOST', `10.3.9.161')dnl
DAEMON_OPTIONS(`Port=smtp,Addr=10.3.9.161, Name=MTA') dnl
DAEMON_OPTIONS(`Port=smtp, Name=MTA') dnl

Looks like sendmail is having trouble binding to port 25. You might want to check with netstat and make sure that nothing else is bound to that port.

nmap -sS -O 127.0.0.1

Fixed.

from : define(`SMART_HOST', `10.3.9.161')dnl
to : define(`SMART_HOST', `hostname')dnl

Working Fine now.
