Like Mark Drake <[log in to unmask]>, I use a (Mac) Eudora plug-in that allows the inclusion of arbitrary header fields. And like Mark's, the one I use also requires you to manually change the settings in order to switch between using a "Resent-From" header and not using it. The plug-in I use is named "Eudora RSVP Prefs". I got it from a mirror of the Info-Mac archive. Here is the brief description of the "Eudora RSVP Prefs" plug-in. Abstract of INFO-MAC archived encoded Mac binary file 'comm/inet/mail/eudora-rsvp-prefs-14.hqx' Uploaded 01/09/96 5500 bytes From: Andy Fragen <[log in to unmask]> Subject: Eudora RSVP prefs v1.4 This plug-in came out of the frustration of not being able to change the 'From:' header from the standard format user@host (Real name) to anything else Support for X-Headers Ability to edit the 'From:' field from the composition window.
