I am trying to configure sendmail so that I am able to send e-mail to individuals on the internet. My SCO 5.0.6 box is not on the internet and is only addressable on my local LAN. All of the local PC's on the network use POP3 servers provided by my ISP for sending and retrieving mail. Will I have to use my local ISP Servers in configuring sendmail or can I go without? Any help is greatly appreciated.
