Setting up an email listserver or an email-on-demand system on the Macintosh is easy with ListSTAR from StarNine Technologies. The ListSTAR software can manage both email lists and email-on-demand services, and can be extended and integrated with other programs using AppleScript. There are POP and SMTP versions of ListSTAR; the POP version requires a separate mail server, while the SMTP version requires a consistent Internet connection and receives mail directly. A fully functional 30-day trial is available; upon payment, the user enters a serial number and the software remains installed and running. StarNine offers substantial educational discounts--prices are available from their Web site. ListSTAR is a relatively inexpensive and easy to use program for managing email lists and email-on-demand systems.
