What’s a Top-Level Domain?
The top-level domain of an email address is the part after the last period. In the United States we
are used to seeing top-level domains such as .com, .org, and .edu that indicate the type or
organization. In the rest of the world, however, the top-level domain usually identifies the country of
origin — for example, .ca for Canada, .cn for China, and .fr for France. For the United States, .us is used
although you rarely see it.
Spam, or junk email, is a serious problem for most email users. Outlook provides you with some
powerful tools to detect and filter spam. By understanding these tools and using them efficiently,
you can greatly reduce the negative impact spam has on your productivity.
