I am assuming that passive probing works the I believe the percentage is just for one message - it rotates through the list and gets around to everybody eventually. (I can't say for sure because we haven't gotten around to install the Sendmail fix that would let us do probes here yet, but that's how I interpreted the documentation.) Of course the percentage would determine how many messages it would need in order to get the whole list probed. Margaret King ([log in to unmask]) Michigan State University
