CustomMailer tests your internet connection as the first step in the SMTP Setup Wizard and also before sending the first email for a given message template if you have “Verify Internet connection working before first Send” feature is selected in Preferences. The test is performed by trying to open an HTTP socket on any one of 5 popular web sites (Yahoo, IBM, MSN, Sun, and AOL), which is essentially the same test as running your browser and verifying that you have access to the World-Wide Web.
