I have started Sky broadband today the broadband or web works fine but I cannot send emails, this problem is the same one I had with Vodaphone so I think it may be a problem with the green box down the road, the router works fine if I want to look something up on the net but Whats App will not work nor will email

Check your Sky Broadband Shield settings, which by default may be blocking them: https://www.sky.com/help/articles/sky-broadband-shield-using
