Can you not use gmail?
Sign up for a gmail account, then in settings look for the "Forwarding/pop/imap" option -
http://mail.google.com/mail/#settings/fwdandpop - for me.
You can use IMAP or POP3 for incoming messages, and their SMTP for outgoing.
Outlook 2003 - Help Center (this is for setting up IMAP, SMTP, in Outlook 2003, there are other help pages for other combinations).
It has funny port numbers compared to "normal" email accounts, so follow the instructions, but it works like a treat.
