Hi, what should one set in order to have VERP but not always? If I set VERP_DELIVERY_INTERVAL=3 it never verps. If I set VERP_DELIVERY_INTERVAL=1 it always verps. Does it apply only to lists not yet created? Did I forget to set one variable? (I'm using today's CVS version. I had the same trouble a while ago. Personalization and other verp features work correctly.) -- Fil
