Hi! We're running listserv v1.8d on WNT4 A person is using a mail client like Outlook Express, Netscape Messenger to read their mail. They choose to view their mail sorted by conversation. To take advantage of this, they modify on the account management page on listserv to receive their listserv mail with the Mail Header style: LISTSERV-style, with list name in the subject. If someone were to send a message to the list and cc someone, then you will not be able to see who the message was cc'ed to without looking at the full headers of the message. It inexplicably changes the CC header of the email so they can't see that others were cc'ed on the message I do not think this is supposed to happen and I was unable to find documentation on a fix for this. Any help would be appreciated. Cele Bruce -- *************************************************************** Cele Bruce Fermi National Accelerator Lab [log in to unmask] P.O.
