[Mailman-Users] unsubunscription without confirmation

[Ako Ito]

hello mailman gurus,
recently upgraded our mailman 2.0.6 to mailman 2.1.3.. is there a way of unsubscribing to mailman 2.1.3 without confirmation.. we are using the weblist-leave option.. also is there an option on mailman where i can create a name based content filter on the subject and body of the message to automatically discard emails that has foul words..

thanks,
allan
