Yahoo has started allowing creation of Mail Alias. This allows an existing Yahoo Mail user to create a new Yahoo Mail ID and then use it from their existing mail account.
Here are some text extracts from Yahoo about the service:
mail sent to or from this new address will appear in your mailbox with the rest of your mail. You can send from this new address by selecting it from the pull-down menu when you compose.
Well, first of all — because it’s free. Considering how hard it is to find free stuff anymore, you might want to jump on the offer for that reason alone. But more importantly, with your hectic and complicated life, it’s highly-possible that one email address simply isn’t enough. You may find yourself in dire need of an extra one just for work? Or maybe one for the family? Perhaps one for school? When you do need it, Yahoo! Mail lets you create one extra email address free. Use it exactly as you would your primary address. You can even have messages to both addresses delivered to one Inbox. Remember though, to keep greedy people from taking advantage of our hospitality, only one extra email address per account.
You can also sign in to your Yahoo! Mail using this address.
Unlike GMail which allows adding any existing mail ID irrespective of being GMail ID based on verification, this service of yahoo allows only newly created Yahoo Mail ID and previously created Yahoo Mail ID’s cant be used.
This feature called Extra Mail Address can be used opted by going to Mail options page>Mail Accounts. There below you will find the option with all the details. Alternately use this link ( http://edit.yahoo.com/config/list_alias?.src=ym ) and paste it once you login to your mail account.
Is the service really worth with the restrictions?
