No problem. In ye olde days, people ran X-windows on 386s with 8MB.
Without a GUI, this box will be plenty fast enough.
Squid can use whatever memory you give it, but the hard disk is still a
lot faster than the dialup.

  With a dialup connection, I suggest you look at wwwoffle . Its a web
proxy designed for dialup connections, and caches for off-line browsing.
It can do blocking, monitor specified pages etc. Users can request pages
to be downloaded on next connection. Its probably a lot lighter than squid
too.

Check the 'shorewall' frontend.

 /etc/ppp/ip-up.local  :   /usr/sbin/sendmail -q

Of course, 'sendmail' is really a link to postfix :-)
And put a line to start fetchmail in the same file.

Its standard feature of sendmail and postfix.  sendmail -q
