Yahoo Email Accounts
Yahoo has made a decision that anyone who sends out a large volume of email is automatically considered a source of spam, and apparently there is no recourse. If you are trying to register using a Yahoo account you can try adding us to your white list by following this procedure:

• Open your Yahoo mailbox.
• Click Options | Mail Options.
• Click Filters.
• Next, click Add Filter.
• In the top row, labeled From header:, make sure contains is selected in the pull-down menu.
• Click in the text box next to that pull-down menu, and enter game-ex.com
• At the bottom, where it says Move the message to:, select Inbox from the pull-down menu.
• Click the Add Filter button again.
