But one of the most underadvertised benefits of subscribing to mail plus is probably the most useful email feature I've ever seen/used. If you sign up for their premium service, sure you get 2 gigs of storage, you get no graphical ads on the mail interface, you get no ads in your email, you get pop access and forwarding, but you also get what they call AddressGuard.

AddressGuard lets you create hundreds of email aliases that still go to your yahoo account, but that you can create and delete on a whim. I never give out my real email address anywhere online because whenever a site asks me for my email address, I create an alias specifically for that site and give that to them. I still get whatever email they need to send me, but the second they sell my email address to spammers, I just hit delete and any spam they send to me just gets bounced back.

This feature alone is why I signed up for $29.99/annually for Mail Plus, and now that they've upped the storage and lowered the price, I think it's a steal.
