Set the fourth pref to the SAME THING as the second pref, unless you have access to *any* list server on which you can create mailing lists to handle the outgoing mail load for Conversant. This is an EXCELLENT way to reduce the server load, but not necessary until you get into a busy production environment with lots of messages.

Unless I'm in the wrong place, I think you mean that it should be left blank unless you say YES to the second pref.
