[Mailman-Users] unsubscribe from all mailing lists

[Dimitrios Karapiperis]

Hello

is there any way to unsubsctibe a user from all the mailing lists on a host?

I am utilizing Mialman's web scripts through my php files and I make any 
subscriptions and deletions
( I don't like the idea to execute shell scripts through php)

version
mailman-2.1.9-4.el5



Thanks in advance
