the big advantage of the fetchmail approach that the initial poster was asking 
about is that it does not require special configuration of the upstream mail 
server.

I definantly agree that it is not the best possible approach. but as far as I 
can tell, every approach that's better requires cooperation from a mail server 
that does have full-time Internet connectivity. unfortunantly that's not always 
available (at least, not available at an affordable price in time and money)
