how can I filter junk mail on my iphone?
Apple Mail on my MacBook Pro filters my junk mail so it doesn't appear in my inbox. But on my iPhone, all my junk mail appears in my inbox, even stuff that doesn't show up in Apple Mail on my laptop. Is there any way to prevent junk mail from appearing on my iPhone? And I can't use iCloud since I can't use an icloud.com email address.
Thanks!
iPhone 6, iOS 9.1
