The command to free a held list is
FREE listname pw=xxxxxxxx
(you may, or may not, need to include your password)
However, before you do that you need to determine *why* your list is held,
if you didn't issue a HOLD command. If your list merely exceed its
daily threshold, no harm in freeing the list, but if it is something else,
well . . . If you don't know why the list has been held your really
should determine *why* it is held before you try to free it. Douglas
