I know nothing about VMailserver, and it isn't likely many others here do either. After all, we're all using LISTSERV(R) instead of something else because we found the best product and know it is worth it. Will your product trap duplicate messages? If not, an answer is gone. Listserv will trap and not send out duplicate messages, which most vacation msgs are. LISTSERV also has other techniques for keeping mailloops from happening, including an adjustable level of messages per day and only accepting postings from list members. Many vacation programs don't show the return address on the "out of office" message to be the same as the subscriber, so they don't get posted. Of course the dream we ALL have is that people set up their rules for vacation messages to be sent to NOT include lists, and that they'll also set the lists to nomail, so there won't be any msgs to reply to. But....we know how our users/customers are.....and indeed, some mail programs can't handle NOT sending to lists. Good luck....and consider LISTSERV(R). No I don't work for them. I'm a happy customer since late 80s, though. dan
