Oh, right, the connection with Renewal is only the NORENEW subscriber setting. I've been keeping everyone else on NORENEW while I test various techniques on multiple subscriptions of my own, with ungodly short timing (2 days each for passive probing and for renewal cycles). I'm deleting the Renewal= keyword on my larger list, setting Auto-Delete= Probe(30), and setting all subscribers to RENEW. I have a smaller list I can use to continue experiments with Renewal= settings, with myself as guinea pig again. Hal Keen
