the easiest way to config fetchmail is with a python script called fetchmailconf
you might already have it or 'm sure there is a package for your distribution
home page
here
type:
fetchmailconf
and just fill in the blanks
this will put your mail in the mail spool
my favorite linux program for reading and sending mail is
Pine
it's not included in some linux distributions anymore for some unknown reason ???
it's a little different to compile and install so take your time
if you can't understand read instructions from a Beyond Linux from Scratch mirror
also some people use web based interface through appache to read send mail
squirlmail or whatever -- i use wemail cause i'm runing a pop3 server not imap
also full gui programs like ximian evolution will also interface quite well with your local mail spool
(i think i never tried it but i can't imagine you can't do it)
