You're very welcome; glad it worked. To join the Eudora-Win discussion list:
NOTE: EVERY COMMAND SENT TO THE GAZELLE SERVER *MUST* HAVE THE WORD "GAZELLE" SOMEWHERE IN THE SUBJECT LINE! If you forget to do this, your message will be ignored by the server -- that is, you will not receive a bounce, an error, or any other form of reply. FYI, the word "Gazelle" is case independent -- it may appear as "Gazelle," "gazelle," "gaZEllE," etc. It does not matter where the word appears on the Subject line.
Hermes Aurora is not yet functional [in a useful sense], but it is getting closer, in an alpha-test stage for those who donated to the project. https://www.indiegogo.com/projects/hermes-mail-8-0-the-final-stretch/
Pandora is a working alternative. https://www.drivehq.com/web/brana/pandora.htm
