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
