Troubleshooting

    ASP allows you to send emails using a functionality called CDOSYS. By creating email content and sending emails using ASP directly, you don’t have to add any extra components to your code. We recommend that you use an SMTP relay that requires authentication. Because of stringent anti-spam filters, sending mail through unauthenticated SMTP servers (including the localhost relay on Cloud Sites) can result in delays or undelivered email. Before you start using CDOSYS to send email, it’s a best practice to test your code.
