The author writes "The Email client was an extension of a Web CGI interface for the POP3Client.pm. First I migrated to the CLI interface, which was real ugly, but it gave me a basis for the application. Then I moved over to the Tk interface, and started building features. Presently the ability to check and send mail, as well as configure a pop3, smtp, account name, password, and reply to address are included. The interface for reading/deleting mail is clunky, but under development."
