This article gives you the steps to review your account settings to ensure that your account is functioning properly following a possible compromise.

First, if you suspect that your account has been compromised you should change your password immediately. After you have changed your password, we recommend you review your account settings to ensure that everything is configured correctly.

To review the forwarding address listed on your account:

1. Go to your Yahoo!7 Mail account.
2. Select Options | Mail Options.
3. Select the POP and Forwarding at the left.
4. Select Set up or edit POP & Forwarding.
5. Select Web & POP Access.
6. Select Save (or Save Changes in Mail Classic).

If you do not see a forwarding address set, then mail forwarding is not set up for your account. Mail forwarding may require a Mail Plus subscription in some countries.

To change the name in the "From" field and adjust the "Reply-to" address:

1. Sign in to Yahoo!7 Mail
2. Select the Options menu in the upper-left corner, and select Mail Options from the pull-down list.
3. From the list on the left, select Mail Accounts or Accounts (depending on the version of Yahoo!7 Mail you are using).
4. Select Yahoo!7 Mail under Accounts.
5. In the "Sending Name" or "Your 'From' name" field, provide your name exactly as you'd like it to appear within your outgoing messages. You will need to write something in the name field.
6. If you'd like a different return address to be included, you can change this information at this time too. Just enter it in the "Reply-To" field, you may need to select Change reply-to address to bring up the "Reply-to address" field depending on your version of Yahoo!7 Mail. If you leave this field blank, your Yahoo!7 Mail address is the return address in your outgoing messages.
7. Select Save in the upper right corner to save your changes. 

Note: You have to write something in the "Name" field. If it is left blank, whatever was written there before will be restored, and your changes won't be saved. The "From" name field can't contain special characters such as the "@" symbol. Also, it isn't possible to hide your email address when sending messages from a Yahoo!7 Mail account and the address in the "Reply-To" field can't exceed 40 characters.

Please also note that any contacts to whom you sent mail prior to changing the "From" field may still have your address saved with the old name, or with any name of their choosing. This means that their replies to you may display whatever name their address book contains for you.

To review your security questions and alternate email address:

The alternate email address and security questions can be used to reset the password listed on your account. We recommend that you review your security questions to make sure that you recognize them. You can review your questions by following these steps:

1. Sign into your Account Information page.
2. Under "Sign-In and Security," select Update password - reset info.

Your security questions will be displayed with the answers hidden for your protection. If you do not recognize the questions displayed, we recommend that you add new questions. To check your alternate email address:

1. Sign into your Account Information page.
2. Select Update your contact information.
3. Review the email addresses listed on your account to ensure that no suspicious addresses are listed.

You should make sure any alternate email address listed on the account belongs to you. If you have an alternate email address listed that is not verified, we strongly recommend that you verify your alternate email address so that you can easily recover your password in the future.
