Promail is the PenTeleData email server which supports SMTP Authentication, SSL connections, and uses Sender Verification to allow users to send email. SMTP Authentication requires that a login name and password be used whenever a user sends a piece of mail. This will dramatically reduce the amount of SPAM which moves through our system, as well as completely eliminate relaying on our servers. Using SMTP Authentication, PenTeleData customers who travel can now send email, using their existing accounts, regular email software, from anywhere in the world! SSL (Secured Sockets Layer) gives our customers the option of digitally encrypting their incoming and outgoing email for added security.
