iphone mail not showing mail that shows up in Apple Mail mailboxes on iMac
My imac get all my mail just fine. Both accounts I use for mail are IMAP. I have quite a few mailboxes for Friends, Family, Internet orders, etc. Mail that comes to my iMac that goes into those folders never shows up on my iPhone. It caused a real problem the other day when a friend couldn't make it to a meeting downtown and sent an email that I would normally respond to but I never got it on my iphone. Any thoughts on how to cure this? I don't see a way to sync them totally. I don't use iCloud.
iPhone 6 Plus, iOS 12
