subscribe users by email from list admin?

Is there any way, in mailman, to subscribe a user (or users) via an email from an email address other than the one being signed up?
E.g., I imagine a simple online form, including an email entry field, that fires off an email upon successful submission, that subscribes that user to a list. But I can't set the from: address of this email to the subscriber's address. I can set it to a list-admin address, if that helps.
By the way, I realize there are commands in /bin that do the equivalent. As far as I know, I can't easily get the place I have the online form (Wufoo.com) to kick off those commands.
Thanks, Matt

If you send a 'help' command (Subject: or first body line) to LIST-request@... the response will include

I think it would be worth putting it in the admin guide--some kind of section devoted to programatically subscribing & unsubscribing people.
