Hello Asif:

You have to do the following:

1. Setup DNS MX record entries for each of the servers to point to the same machine - if you are not running the DNS on the linux box/ get your DNS admin to put entries the MX records for the other two domains
2. Now edit the file /etc/sendmail.cw and add the entries for the other domains eg.

modelfincorp.com
modelchit.com

that is basically it. NOTE that user1@modelfincorp.com will be the same as user1@modelchit.com unless you set up your /etc/aliases files or use some mail processor like procmail .
