I've just received a SUBSCRIBE request from an address that says
[log in to unmask]  I've written back to ask where the list
messages will go, but I wonder if others have received these and
know whether I am being unduly cautious.
the mail i sent originally came back to me due to a typo in addressing
          i was merely lazy and resent it as is without removing or
          retyping another subscription
                                       sorry if i made you paranoid
