I've used Listserv for years and had little problem with Out of Office messages. But yesterday I set up a small list with the header info as below for a team of Groupwise users. Within minutes the system was bombarded with dozens of Out of Office replies actually going back to the list and being redistributed again (near meltdown !!!). Does anyone know if I can I set Listserv to avoid this problem.
