Sorry, but NEWSGROUP is a usenet keyword which would have NO meaning in a LISTSERV environment unless some conditions were met. One of these conditions would be that all peers of the same list had the same name. Another one would be that the list nodeid were NOT required to mail to the list: Newsgroup: LSTSRV-L With this indication, and even assuming that all peers were called LSTSRV-L (which is the case for this list but not for all of them), you would need an extra table to know where to reply to. All of this is a little pointless anyway. You might be able to change RICE mail if needed, but certainly not the existing stupid mailers, especially not the VAX mailers which send errors to the FROM field address. Eric
