Well, having just tried to find out which user of a list was "bouncing" (since I had received several), I realized that the user had been automagically unsubscribed, but I hadn't gotten to that. Thus, I spent all sorts of time looking for that user both on the list, as well as analyzing mailer tables and re-direction via auto-forward. The reason for multiple bounces was that the list's high-volume mail was in-distribute before the first bounce was able to be processed by the auto-delete logic of LISTSERV. I'm sure there is a moral to this story ;-) /Pete
