Icloud doesn't receive all email
I'm trying to access emails from the website version of my icloud account, but it only recieves email specifically from my email app's inbox, and not its junk folder.
Understand that I am not referring to spam; pretty much any email sent to me by anyone other than those in my contacts list gets sent to the junk folder, and I never have to deal with the usual spam that comes with gmail and the like. As a result, Icloud.com pretty much only recieves emails from my relatives and dentist.
Does anyone know how to properly sync the two so I can actually continue to use my @me email? If not, I have to switch everything to an email that actually works.
Thanks.
