Tip: Yahoo! AddressGuard Disposable Address
I have been a big fan of Yahoo! Mail for long time for its Ajax sleek, intuitive interface, the unlimited storage capacity and the mobile friendly format . (I choose the affordable Mail Plus option to get rid of the ads in the bottom body email).
(Yahoo! does not offer yet the option send from a different email address than your . and the new disposable email address we show you later. For people who think using @yahoo.com is not as cool as @gmail.com, they could create another gmail address and use mail forwarding to manage their all emails from Yahoo!) .
But one of the slickest things I want to share with you today is the available Yahoo! disposable addresses.
Almost all the great Web services we’ve shown you, require registration with an email address and password. Unfortunately, some of them might exploit it to serve different marketing purposes. After the jump, we show you how…
Yahoo! mail addresses that situation by giving its email users the option to create a pseudo email address with the format:
anybasename-anykeyword@yahoo.com
User can use that address to register on the Internet. Emails received to that disposable address can be redirected to different email folder within your normal Yahoo email account. As soon as you see exploit for Spam, you can just simply delete that email address and create another one.

To set up, select:

You also have the option to send out email with the disposable address if you choose. After the setup, in the send email you will see the drop down menu for Send from.

















It’s not widely known, but Google Mail (gmail) offers a similar ability, but using a ‘+’ instead of a ‘-’. No need to set anything up in advance, it just works automagically, but you can set up filters on particular addresses if you want. Don’t think you can send from that address though.
Unfortunately, there are too many lazy programmers and web developers out there who don’t appreciate that ‘+’ is a perfectly valid character within an email address according to the relevant RFC, and reject entry of any such email address as “having invalid characters”.
Aaargh.
Gmail has the same thing. It’s accessed with a + symbol.
Mails sent to:
fred+anythingyoulike@gmail.com
Will be delivered to: fred@gmail.com
Better yet, in Gmail you don’t need to set them up in advance. You can make one up on the spot when filling in a webform and (optionally) later set up a filter in your Gmail acount.
You are right about the + with Gmail, however, I think you can not delete that email+abc@gmail address. You keep receiving the spam.
With Yahoo! as soon as you determine the spam got hold of it, you can delete that disposable email address.
And lots of sites will not accept the sign + in the email field.
