I use a service called POP3Now!, at
http://www.pop3now.com. It
basically gives me a webmail interface for my existing email
accounts. I haven't a clue about how it works, other than to say
that it can gather email from multiple accounts without actually
removing the email from those accounts, so I can fetch the same
messages with my mail client of choice when I'm able. It's not a
perfect solution but it does what I need it to do.
