How to configure mail on auto commit

[Ramesh Chander]

Dear all,
  I want to configure auto mail commit message to the development team in CVS.
My CVS repository is on SUN sparc m/c and my mail server is a linux  m/c named
Lancer. can any body guide me the steps to do so. I will be thankful if you tell
me the entires to be put in all files for this.
Taking an example.
Repository is  /users/local/projects/cvsroot
users to be mailed  address@hidden, address@hidden

Also Is it possible that I can chnage the permission for commit/remove etc for
different users. For example some user can only do checkout not Commit and some
can do it.

Thanks
Ramesh Rohilla
