Simple Mail Transfer Protocol, or SMTP, is the server that sends mail with email programs. When you set up an email account, you must define the SMTP address to ensure your email gets to your recipients. You need to know the exact name of this address if you are configuring or troubleshooting an email program. Knowing how to find out your SMTP address quickly and accurately saves you time and frustration.

Locate the name of your SMTP address in the response, which displays immediately after the word "Pinging," and write it down for future reference.
Using Outlook Express
Open up Outlook Express and click "Tools," "Account Settings" and then the E-Mail tab.
Double-click the email account for which you need the SMTP information.
