sendmail authentication

hi,
  I am using sendmail 8.12.10 with sasl authentications for the user.
We have to restrict some of the users to send mails outside and receiving from outside while the others should have no restrictions.
  Could anybody suggest me how to accomplish this.

  Thanks.

hi SandyKalugdan,
    Thanks for your reply. This is ok. But there is a loop hole if the user uses other machine and then sends mails to outside. Our sendmail is configured to use user authentication. So restriction should be user based not ip based.
Well, I did not get any proper solutions. Now we made a serparate mail server  for those people.
