The main reason we have chosen to implement SMTP Authentication is to reduce spam. Since all users of our Promail Server must now log in to send email, SMTP Authentication will greatly reduce the number of messages which are sent through our servers from fake email addresses. When you send an email with SMTP Authentication, the email server will attempt to verify that you are a PenTeleData customer and will not allow you to send email otherwise.

In addition, PenTeleData users who travel will now be able to send email through the PenTeleData outgoing email server from anywhere in the world, as long as SMTP Authentication is set up properly in their email software.
