You can connect to your e-mail server either by using a local area network (LAN), a dial-up networking connection by using a traditional (such as a 28.8 or 56K) modem, or your own dialing program by using a modem.
Through a LAN
With a modem
Using another dialing program
If you would rather prompt the server when you want your incoming and outgoing mail to be delivered, you can connect to the server manually. For example, you might want to connect manually if you have a slow connection to your e-mail server using a dial-up networking connection, and you don't want to wait for the server to connect automatically.
Note Wireless networks and DSL or cable modems are considered LAN connections because they generally maintain a constant connection and do not require a connection to be manually established.
