Most mailing list management software allows a list owner to configure
a list to use unconfirmed subscriptions, however, it is A Bad Idea to
choose this configuration, because it makes the list vulnerable to
forged subscription requests, and places the list server at risk to be
blacklisted. If your list is hosted on your personal workstation, your
decision to use unconfirmed subscriptions will probably affect only you
and your list subscribers. On the other hand, if your list is hosted on
your service provider's list server, your decision may affect a very
large number of people, and could put you in violation of your service
provider's acceptable use policy. Our list service policy explicitly
prohibits the use of unconfirmed open subscriptions.

Everywhere that I've run into Majordomo in use,
Majordomo is set to confirm each subscription
request by requiring the would-be subscriber to
respond to an automated subscription-confirmation
email.

Can this feature be turned off by the Majordomo
administrator, thereby allowing people to be added
directly to a list, without having to respond
to a confirmation request?
