[PyKDE] Unsubscribing from a different e-mail address

[Calvin Spealman]

I am no longer able to send mail from the address I am subscribed to
this list on, but I can receive mail on it. This means I still get all
of the PyKDE (and some other lists) messages, when I am currently
unable to spend the time reading it. I tried to unsubscribe, but as I
can't send the request from the proper address, how should I do this?
