jumex's Anti-Spam (UCE) filter mail scripts

NOTE: This is designed for UNIX-like systems.

For advanced UNIX users:

If you are using either pine, elm, mutt, or any other email client in UNIX that allows you to pipe (|) messages to UNIX commands, then these three Korn Shell scripts might come in handy for taking care of false negatives and false positives without having to edit your .whitelist, .blacklist, and .legitlists files directly.

Make sure to put these files in a directory that is in your PATH, or you won't be able to execute them from within you email program.


This is another simple script I wrote that displays mail headers in a mail file from the command line. I use it when I get a "you have mail" message, but I don't want to load up my mail client to see what it is. I hope you find it useful too.
