i have created a list with the following command in the command line

then i got a mail in my mail box saying

The mailing list `mtech-cs-2010' has just been created for you.  The
following is some basic information about your mailing list.

Your mailing list password is:

    *****

You need this password to configure your mailing list.  You also need
it to handle administrative requests, such as approving mail if you
choose to run a moderated list.

You can configure your mailing list at the following web page:

    http://dcis.uohyd.ernet.in/mailman/admin/mtech-cs-2010

The web page for users of your mailing list is: 

    http://dcis.uohyd.ernet.in/mailman/listinfo/mtech-cs-2010

You can even customize these web pages from the list configuration
page.  However, you do need to know HTML to be able to do this.

There is also an email-based interface for users (not administrators)
of your list; you can get info about using it by sending a message
with just the word `help' as subject or in the body, to:

    mtech-cs-2010-request at dcis.uohyd.ernet.in

To unsubscribe a user: from the mailing list 'listinfo' web page,
click on or enter the user's email address as if you were that user.
Where that user would put in their password to unsubscribe, put in
your admin password.  You can also use your password to change
member's options, including digestification, delivery disabling, etc.

Please address all questions to mailman-admin at dcis.uohyd.ernet.in.
