I will echo Good Ol' Pete and Dan Wheeler in that the central question is "why?" here. What is the result desired? Reminds me of occaisions in the past when people have suggested that Eric change the code in a specific way to do this or that which generally won't work. The best responses, other than Eric's describing the flaws, have been those saying "describe the result you want, not how you think it should be done." Same sort of thing. As to Dan's daily SET listname MAIL FOR *@* , what if you have digest and index subscribers? And if you have RENEW the resetting of everyone's sub every day will make hash of the renew process. I've already expressed my views on keeping a list perpetually locked. Again, the question is WHY? Douglas Douglas Winship Hays County, Texas [log in to unmask] Secondary AUTOCAT Listowner MEDLAB-L
