With some ISPs it is important to use the primary account name and not necessarily the account name for the individual e-mail address you are using. That is the name to the left of the in your primary e-mail address. The account name is usually just the primary account name from your ISP. You will need to get this information from your hosting company or ISP. The Server Name and the User Name are the two important areas to focus on. The Description is not important, but if you configure multiple SMTP accounts it would be a good idea to enter a description. Highlight an SMTP account and click the Edit button, or if you want to add a new account click the Add button. The section that you want is at the top of the right-hand side.
