Configuring SMTP Authentication in Windows Live Mail

Last Updated: Fri, 22 Apr 2011 > Related Articles


Follow these steps to establish SMTP authentication for Windows Live Mail.



About SMTP Authentication

SMTP stands for Simple Mail Transfer Protocol. It 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 will help to improve security and reduce SPAM originating from the Cox network. It will also help to ensure that mail sent from the Cox network is from legitimate customers. This is critical to maintaining the integrity of the Cox network and our reputation with other large Internet and Email service providers.




In Windows Live Mail, right-click the account and select Properties.




From the Servers tab, under Outgoing Mail Server, select My server requires authentication.

Click Settings.




Select the Log on using radio button, and enter the email address and password. 

Click OK.




From the Advanced tab, under Server Port Numbers, change the Outgoing mail (SMTP) port to 465 and select This server requires a secure connection (SSL).

Note Port 465 is preferred and supports SSL; Port 587 is clear text.




Click OK.
