from the doc: 'Using bigE Pro is easy - just install bigE Pro on your home, or target PC - the computer you wish to e-mail. The an e-mail client is used to send e-mails to bigE Pro. Any e-mail program, such as Outlook, Netscape Messager, etc, can be used as a client. You can also use the bigE Client to construct messages (freeing you from having to remember all of the commands), but use your own client to send them. bigE Pro must be installed on a computer that is connected to the internet (dial-up works just fine!), and you must have access to a POP3 e-mail account (no free-mail accounts supported).'
