getting of the bloody list

I have tried the following:

>1)
>Send a message to FTGZG-L-REQUEST@BOLTON.AC.UK with the text
>SIGNOFF

>NOT Unsubscribe (dunno why)

>2)
>Send a message to MXSERV@BOLTON.AC.UK
>with the text
>SIGNOFF FTGZG-L

But no joy, can someone please get me off this list. I will be shutting
down this account,
