This article describes aliases and whether Ymail and Rocketmail addresses may be used as for an alias.

Aliases are an extention of a Yahoo!7 Account which are intended to mask the account's primary Yahoo!7 ID. Generally, an account's primary Yahoo!7 ID serves as the main prefix for the Yahoo!7 Mail account it is associated with. If a primary Yahoo!7 ID is used to communicate via a product, it can expose the Yahoo!7 Mail address associated with it.

Please note that an alias is not an email address. Therefore, it is not possible to send and receive emails using your alias. By setting up and using an alias on your Yahoo!7 Account, you will keep your Yahoo!7 Mail address private and reduce the odds of being targeted by spammers. For this reason, previously existing and new email addresses (including email addresses under a Y!Mail and Rocketmail domain) cannot be used as an alias for a Yahoo!7 Account.

In order to set up an alias for your account:

1. Go to your Yahoo!7 Account Information page.
2. Click Manage your Yahoo!7 aliases under Account Settings.
3. Click Add an alias.
4. Create your new alias and click Save to the right.
5. Click Close to return to the Account Information page.

Note: While you are able to add/set up to 6 aliases for each Yahoo!7 Account, you may still need to sign in with your primary Yahoo!7 ID when accessing some parts of Yahoo!7. Note, also, that you do not have a separate password for your alias.
