Hi Folks,
Thanks all of you for your quick response. I got the solution.

My Sincere thanks to
(1)Otto, Doug <otto@alldata.com>
(2)Mark.Neill@fanb.com
(3)Larry Chin <larry@sprint.ca

Original Question:
How do I trace back and find out who is the actual sender in the
following command.
/usr/lib/sendmail -f <sender's address> -d <destination address>

Solution:

you should be able to expose the full headers of the mail message
 unless
something along the path the mail took stripped them off ) and see the
entire path used from source to destination

for instance I sent this using sendmail -f god@larry.com -d
larry@sprint.ca.
you'll notice the Received: line actually shows larry@localhost

>From god@larry.com Wed Apr 14 10:24:29 1999
Received: from smtpserver (server [192.9.200.1])
From: god@larry.com
Received: (from larry@localhost)

Date: Wed, 14 Apr 1999 10:22:43 -0400 (EDT)
Message-Id: <199904141422.KAA17200@server.sprint.ca>
X-Authentication-Warning: server.sprint.ca: larry set sender to
    god@larry.com using -f

Thanks,
