Rex, thank you. I've just successfully implemented your suggestion for Eudora. I have a number of list moderators for my lists and not all are using Eudora, unfortunately. They use Outlook, AOL, Netscape, and Explorer. Have you worked out similar modifications to cause any of these email clients to generate the "Resent-" fields? (I suspect the answer is "no," but it doesn't hurt to ask, right?) Steve
