Configuring SMTP Authentication in Windows Mail


Simple Mail Transfer Protocol (SMTP) is the internet standard language used to send email. SMTP authentication requires that a user provide a valid username and password to authenticate before the user is allowed to send email.

SMTP authentication helps improve security and reduce spam originating from the Cox network. Authentication also helps ensure that email sent from the Cox network is from legitimate customers. This is critical in maintaining the integrity of the Cox network and our reputation with other large internet and email service providers.
