Why am I still getting junk?

Still a good deal of junk seems to accumulate, but you think once I upgrade to the newer iOS system this will go away too?

Adjusting settings will not reduce the amount of junk you receive. It will just make sure it stays in the junk folder until the time you’ve set to delete it. Everyone gets tons of junk once their email address has been exposed. If the amount of junk you get concerns you, you can always set it to erase when quitting mail or once a day. Right now you have it set to one week I believe. Junk mail is harmless as long as it’s moving into the junk folder and out of the way. If it doesn’t get filtered and lands in the inbox, that’s when you have to use the junk button at the top your email application on the Mac to tell the computer, this is in fact junk and don’t let that sender land in my inbox again.

You can do this on your phone as well but takes a few extra steps. Swiping an email to the left should reveal the “more” then “move to junk” command. I find it easier to just use a computer.
