I've mentioned before about forwarding e-mail to Google GMail.  Here's a summary of the benefits and features.

• Backup of all e-mail
• Online, accessible from any computer with an Internet connection
• Simple, easy-to-use interface
• Searching for old e-mail is a snap
• Spam filtering
• POP3 access, so you can use any e-mail client (Outlook, Thunderbird, Eudora, etc.)
• You can customize the Reply-To address so that other people never have to know you're using GMail.  Replies will still be sent to your regular address instead of GMail.
• Over 2,600 MB of storage (as of today) and growing

I know there are many of my customers who could benefit from using GMail just for the spam filtering alone.  I used to provide spam filtering with my hosting, but it became too much of a hassle.  It only takes about 5 seconds for me to modify an account to start forwarding all e-mail to another address.

If you're one of the few people on the planet who doesn't already have a GMail account, let me know and I'll send you an invitation.
