[Mailman-Users] Subscribe without Confirmation - Please HELP!

[Miretsky, Anya]

How do I subscribe a user through the email interface with approval? 

I don't want subscribers  to receive confirmations or as an administrator
have to get emails that I have to approve each subscriber.

I am looking for something like this in the subject line:
Approve subscribe password address = subscribersemail

The above doesn't work, does anyone know if something like this can be done
in mailman?
