Douglas, If you manage to do this, would you be willing to share the technical details on this list? That's something I've been wanting to do for some time, for all the reasons you mention. Thanks.

This will allow us to create public announcements (and send more sensitive information to private lists) through automated systems without having to worry about forgery, a wait for moderation, or interception of passwords or SMTP traffic on the network. Is anything like this on the drawing board for LISTSERV? It seems like a no-brainer "good thing" to be able to accept messages and distribute them without worrying about authenticity or exposing passwords, etc, accidentally. -- DCP
