[Mailman-Users] Making "set delivery off" default for new users

[Tom Wolfe]

Hello -- I imagine this is a strange request, but I'm wondering if it is
possible to set the options of a new member with default of "set delivery
off"?

E.g., if they are subscribing by email, would something like the following
be possible:

To: list-request at domain.com
From: myemail at address.com
Subject:
subscribe
set delivery off


.... I tried it, and naturally it didn't work. But is something like this
possible?

I'm making a list that will have an easy-to use web interface to access
list archives, with mailman as the backend--but don't want people to get
email from the list unless they abosultely want it; yet I want only
subscribers to be able to post...

Thanks,
Tom Wolfe
