However, there is a limit to the number of lists you can send an identical message without triggering the Spam Filter in LISTSERV® > We've tried it here and it > doesn't seem to like a space delimiter or at least I think thats the issue. Most mail clients use a comma delimiter. > Should the delimiter be a comma/semi colon or is it not possible to do > this in one shot? Comma, e.g.... To: [log in to unmask], [log in to unmask], [log in to unmask], [log in to unmask] Again, if you use too many lists, LISTSERV will reject them, even if you send them separately. If this happens, you will need to create a "Super list" and make all these lists "Sub lists" of the Super list. Now you just send 1 message to the Super list which in turn is distributed to all Sub lists.
