Is there any other way to restrict users/systems/domains/IPs to use sendmail server except listed in /etc/access(.db)?
I just want to secure sendmail server so that none of the other system can send mails/messages/spams from sendmail server except we have mentioned the IPs of LAN systems in /etc/access.db.

You can configure Sendmail to utilize authentication and not relay unless a user has been authenticated.  Check the relaying configuration portions of the docs and also AUTH.

Here is another, more advanced configutation how-to's:

Hope this helps!
