Does anyone know what "Delete and report junk" actually does on iOS? Is it a placebo button like "Close elevator door" and "Push button to cross street," or does Apple actually do something useful with those reports?
I have my suspicions that "Delete and report junk" is about as effective as marking email as "junk" in the Apple mail client. That is, the Apple mail client will happily drop junk mail into your inbox no matter how many times you mark mail from foo@bar.com as junk. And yet I have to go dig in the Junk folder to find the shipping confirmation from orders@company_you've_heard_of.com
