If you set ALLOW_OPEN_SUBSCRIBE = Yes in mm_cfg.py, you will be given
the option to allow unconfirmed subscribes on a list on Privacy
options...->Subscription rules->subscribe_policy. Alternatively, you
can set subscribe_policy = 0 for a list with bin/withlist.
This is not really recommended. See
a few of the reasons why.

This requires the subscribee's address be written to a file to be read
by the command.
See the thread with subject "[Mailman-Users] Admin (un)subscribe via
wget or email w/out confirms" beginning at
for a way to use wget.
You could set up your web forms to post to the admin mass subscribe
URI, but you may not be able to do this without revealing the list
admin password to anyone who looks at the HTML source of your form.
Again, see the above thread.

OK, I won't say that list managers "shouldn't have" the ability to
allow unconfirmed subscribes. I've told you a few ways you can do it,
But if one list manager's ill considered subscription policy has the
potential to get your entire domain blacklisted by AOL and other large
ISP's, you might want to let other list managers in the domain weigh
in on the decision.
