This is a perl script that can build a mailing list by grabbing addresses from any kind of file. It will work from the command line on any Unix or NT server with perl 5. It will also weed-out duplicate addresses from your list. You can merge many lists together in multiple passes if you wish. The lists created by this application will have one address per line, with a linefeed as the return character. These lists will be usable by most bulk mailer programs.
