With Yahoo! AddressGuard, you can easily create a large number of disposable addresses using a simple template:
Basename-keyword@yahoo.com

What's a "base name"? Anything. "ruslINpson," for example. "QEbnut41." All it has to be is a series of letters and/or numbers that no one else is using.

So choose a base name. Then create up to 500 disposable addresses by choosing different keywords. Keywords are a good place to identify what you're using the address for.

For example, if you chose "dairyman88" as your base name, you could create dairyman88-auction@yahoo.com or dairyman88-bank@yahoo.com, etc.

Messages sent to these addresses go to either your Inbox, or to one of your personal folders—your choice, each time you create an address.

If you start getting spam through any of your disposable addresses, just delete the address. Done! See ya, spam.

If I send Yahoo! Mail from my mail client (Outlook, etc.), can I use AddressGuard?
