This have been an issue for a few months now. Our mailing list has grown to a few thousand recipients. We use a web based script to send the email. When sending a small group of email (200-300) we have no problems. When sending to the entire list the page times out and somehow refreshes and resends the email to the entire list again. This puts stress on the server in addition to sending multiple copies to our list. Any suggestions? Should a server based application be used instead of the web script? Is it a server timeout issue?
