In the non-beta  version of 1.5n, "UNSUB listname  (NETWIDE" is perfectly
valid. Just because your server doesn't  have a list called FOO-LIST does
not mean that  such a list does  not exist, and the  request is correctly
forwarded.  I have,  since then,  changed the  code to  make the  NETWIDE
option valid only when listname = '*'.
