Outlook Express Setup
To setup Outlook Express to send and receive mail through RRCNET, double-click on the Outlook Express icon on your computer. When Outlook Express starts up, go to the "Tools" menu and select "Accounts". From the list that appears, click on the "Mail" tab. Click on the "Add" button and select "Mail". That should walk you through a setup wizard.
Other than entering your username & password, you will need to type in mail.rrcnet.org when the setup program requests the POP3 and SMTP mail server names.
