Those "message opened" acknowledgements are being generated because the *SENDER* - the person who posted the message to the list - requested an acknowledgement. There is nothing that the recipient (the sender of the acknowledgement) can do about it, and I doubt if there is anything that the sysadmin at the recipient's site can do about it, either. The culprit here is the *SENDER*. He/she may not even be using GroupWise - there are other email packages that provide the sender the ability to request an acknowledgement. pdr (former GroupWiseGuy) * -------------------------------------------------------------------- * * Paul Russell * Senior Systems Programmer * University of Notre Dame * * Email: [log in to unmask] * Web: http://www.nd.edu/~prussell * * -------------------------------------------------------------------- *
