This has reminded me of a question that was the original trigger for my joining this list back in February and then the problem resolved itself and I never asked. The question is, if the list header contains "Auto-Delete= Yes", with no further parameters, what is the default for the second parameter? The manual doesn't give a clue. I had assumed it would be semi-auto, but events back in February indicate otherwise. A subscriber of mine (who it turned out had ISP problems for more than a week) started bouncing in spades, with every invididual bounce being returned to me. Since the list is a personal support list, and I hadn't heard from her in a while, I posted the info and asked whether anyone else had. Another subscriber who is the owner of another list to which the first person is also subscribed, wrote me privately to say that she wasn't getting any bounces at all. As I was being buried, and my private messages to the subscriber in question were bouncing as well, I found this a little unnerving. My list was set to "Auto-Delete=Yes,Semi-Auto,Delay(4),Max(100),Probe(30). The other list was set to "Auto-Delete=Yes" (with no following parameters). The fact that the other listowner wasn't seeing a single bounce was consistent with what would be expected with "full-auto". It unnerved me because that wasn't what I thought the default would be. Then after several days the other listowner reported that Listserv was probing the address, and the probes were failing, and the subscriber now had the clock set for deletion on her list. She still hadn't seen a single bounce, while I had been seeing dozens. There is a happy ending; the subscriber's ISP problems came to an end; and the subscriber wrote my fellow owner-of-the-other-list about what had happened. We had both already manually deleted the subscriber, but both of us quickly resubbed her. This experience quickly came back to memory when I saw the reports of some listowners seeing Yahoo bounces and others not seeing them. It appears that in this situation, some addressses are bouncing and others aren't. But that wasn't the case with my situation back in February, and I still wonder, what is the default for the "auto-delete" parameter? Dennis
