unsubscribing

["Geri Purpur. Set lm_net digest" <purpurgm@CONRAD.APPSTATE.EDU>]

Can someone please help me.  My E-mail address has been changed since I
subscribed to LM_Net, so when I send the unsubscribe command,
the system does not recognize my address.  The only difference is that
one word has been removed from my address.  Does anyone know how to get
around this?
Thanks,
