The message "implicit destination" is issued if the list name to which
the mail is addressed does not appear in an RFC5322 "From:" or "To:"
line.  This implies that the list name was in a "Bcc:" line.  If you
want to send to a list via "Bcc:", you have to change the list
configuration to allow implicit destination.  The mailman-supplied
default is to not allow the list name in a "Bcc:"
