[REBOL] Re: Selma Source

From: cybarite:sympatico:ca at: 14-Aug-2002 21:16

David, I used Carl's base with some minor mods so called it SELMATE (the new "te" is for Toronto Edition ... it made me smile .... at the time) And created my own %notices.r file .... I couldn't find the one that went with the original Selma.r but this seemed to work. It allows me to add more asynch messages being supported - then send email and do the thing. This version runs in a loop 10 times. It would not run reliably on my machine so I was looking to have a CGI from my webserver to restart it remotely. Let me know if any problems .. I ran it a few weeks ago to demo but the project that I was preping for has not kicked off yet. I still want to use it for my project when it is funded. Good luck with it. ============================= Selmate ================== REBOL [ Title: "SELMA (Open Group)" Author: "Carl Sassenrath" Email: [carl--rebol--com] Date: 12-May-1999 File: %selmate.r Purpose: { SELMA - Simple Email List-Managing Application.(Toronto Edition) Implements an email list server that can run on any server or client.
