What is SMTP authentication?
SMTP stands for simple mail transfer protocol and is an Internet standard for email transmission. SMTP Authentication ensures that only authorized users have access to Email servers.
SMTP authentication is required any time you are away from your home and want to access your email via an email client or a smartphone. If SMTP authentication is enabled, you can access your email from any Internet connection.
- If SMTP authentication is not working or is not set up properly, your email client requests your Email user name and password. Or you might receive an error, such as, "Your server has unexpectedly terminated the connection.'' In many email clients, there is a Test Account Settings button you can click that checks whether you have configured the settings correctly.
You can access your Email without setting up SMTP authentication.
