We are in the process of establishing a private discussion list for family
members of Tax employees loss or missing at WTC disaster.  Until now, we
have only had announcement lists and we now need some help.

We do not have the loop-checking in the configuration, yet one testing
member did receive the following:

Your message is being returned to  you unprocessed because it  appears to
have
already been  distributed to the  ListName-L list.  That is, a  message
with
identical text  (but possibly with different  mail headers) has been
posted to
the list recently, either by you or by  someone else. If you have a good
reason
to resend this message to the list (for instance because you have been
notified
of a hardware failure with loss of  data), please alter the text of the
message
in some way and  resend it to the list. Note that  altering the "Subject:"
line
or adding blank  lines at the top  or bottom of the message  is not
sufficient;
you should  instead add a  sentence or  two at the  top explaining why  you
are
resending the  message, so that the  other subscribers understand why  they
are
getting two copies of the same message.

Will someone please help us identify a resolution to this? Thank you very
much.  Marilyn
