After it was revealed that Yahoo secretly scanned customer emails for U.S. intelligence agencies, now's as good of time as any to leave Yahoo Mail. However, the company has made it more difficult to leave by disabling the automatic email forwarding feature. Reuters reports: While those who have set up forwarding in the past are unaffected, users who would want to leave following recent hacking and surveillance revelations are struggling to shift to rival services, the AP reported on Monday. The company has been under scrutiny from investors after disclosing last month that at least 500 million user accounts were stolen from its network in 2014. The AP said that several users were leaving or had already left the service because of the negative headlines. The company's website says that the "automatic email forwarding" feature is under development and has been temporarily disabled.
