MeltMail 3

Melt Mail is a service that allows you to create a temporary email address that can be used for one-time registrations, or to avoid giving away your personal address. You can even specify how long your temporary inbox will last. Free to use and with no registration needed, Melt Mail allows you to check the expiration of your mailbox in a handy auto-updating pop-up window.

Maximum email storage on the server - 24 hours.
