Boxbe

Boxbe is a service that lets you easily create an email guest list that makes sure you receive email messages from people who matter to you. Boxbes guest list contains only those youve added or invited, just like your IM buddy list or your social network friends page. Anyone who isnt on your Guest List will receive a request to verify his message before it is delivered to your inbox. Legitimate businesses who want to reach you have the option of paying a small fee (that you set and share with Boxbe) to get their message through to you. Boxbe works with Yahoo Mail, Microsoft Outlook or as a public forwarding address.
