Newsletters and mailing lists

I was just wondering what is the best free mailing list/newsletter cgi/perl script that can be found on the web and also where i can find it?

You can find plenty here:

http://cgi.resourceindex.com/Progra.../Mailing_Lists/

I can't recommend one in particular. I wrote one of my own some time ago because the scripts I found didn't do exactly what I wanted. However, it's not tidy enough to be released to an unsuspecting world.

Of course, you can always use http://www.listbot.com or http://www.egroups.com if you aren't inclined to set up a script yourself.
