All Yahoo China email users got a notice last month that they are forced to choose either to move their Yahoo email address from (abc@yahoo.com.cn) to Aliyun email service (abc@aliyun.com) or lose all information after this August.
To choose Aliyun email service, Yahoo China email users will lose all the setting and also cannot receive future email after 2014. I hereby strong suggest Yahoo Inc. could let Yahoo China email users to choose change their email address to the Yahoo US domain (abc@yahoo.com).
