[ILUG] newbie: email server Q

[Dermot Gorman]

Hi,
I installed donncha's sendmail/fetchmail configuration utility and
proceeded to dial up and everything went fine, all email was downloaded
and could be read using pine.
My Q is what how can I configure netscape to download the mail from my
local linux box into the netscape app.? This is probably incredible
simple but i can't figure out what the mail servers name should be in
the preferences box. 
My /etc/hosts file is:
127.0.0.1       p133.redhat        localhost

I've tried using all variations for of these hostnames for mailservers
but it gives the error when i click 'get mail'  of   "network connection
was refused by the server p133.redhat. The server may be not be
accepting connections or may be busy"

thanks
dg
